Neurorehabilitation and Neural Repair

AIMExecutive functions (EF) are advanced cognitive processes that play an essential role in daily functioning and may be of increased importance in cerebral palsy (CP), given the complexity of primary and associated impairments. This study aims to synthesize existing evidence on the relation between EF and domains of the International Classification of Functioning, Disability and Health (ICF) in individuals with CP, and to quantify the magnitude of these associations through meta-analysis. METHODA systematic literature search was conducted in eight electronic databases up to 14 July 2025, examining associations between EF and ICF domains in CP. EF outcomes were classified into inhibitory control, working memory, cognitive flexibility, higher-order EF, and EF composite scores. Outcome measures were mapped onto ICF domains: Body Functions and Structures, Activity, Participation, and Contextual factors, using the CP Core Sets. Correlation coefficients were transformed to Fishers z and entered into three-level meta-analyses to estimate pooled effect sizes. Single moderator analyses examined CP subtype, EF domain, EF assessment type, and mean age. Risk of bias was assessed using the Quality in Prognosis Studies (QUIPS) tool. RESULTSFrom 4637 identified records, 38 studies were included, comprising a total sample of 1633 participants with CP. There was substantial heterogeneity in CP subtype, participant age, and EF conceptualization, while the ICF Contextual factors domain was underrepresented. A medium-to-large association was found between EF and functioning across all ICF domains combined (r=0.26, p<0.001). Domain-specific analyses showed a medium association of EF with Body Functions and Structures (r=0.21, p<0.01), a medium-to-large association with Activity (r=0.38, p<0.001) and Participation (r=0.26, p<0.01). CP subtype and mean age significantly moderated the overall EF-functioning association, with mixed CP and younger age associated with stronger effects. INTERPRETATIONEF are meaningfully associated with multiple domains of functioning in individuals with CP. These findings support the relevance of routine EF assessment and suggest that EF are an important cognitive correlate to consider when addressing broader aspects of daily functioning.

BACKGROUNDThe recovery from sport-related concussion (SRC) is highly heterogenous, with many individuals experiencing symptoms that persist beyond typical recovery timeframes. The early identification of individuals at risk of prolonged symptoms is therefore critical to inform timely interventions and set realistic recovery expectations. Although acute symptom burden is one predictor of future symptom burden, reliance on self-reported measures may limit objectivity and reduce clinical utility in settings where symptom evaluation may be unreliable. In this prospective cohort study, we evaluated the discriminatory accuracy of the CogState Brief Battery, alone and in combination with the Sport Concussion Assessment Tool (SCAT), to classify Australian football players with SRC from Australian footballers without SRC at 24-hours post-injury/match. Furthermore, we examined whether CogState performance and symptom severity at 24 hours were associated with symptom outcomes at one-week post-injury. Adult amateur Australian football players (n=181) were recruited following SRC (n=109 SRC, 86% male) or after a non-injured match (n=72, 90% male). Participants completed the CogState Brief Battery, SCAT and Rivermead Post Concussion Questionnaire (RPQ) at 24-hours and one-week post-injury or match. Area under the receiver operating characteristic (AUC) analyses quantified the ability of 24-hour CogState task performance and SCAT symptom severity to distinguish SRC from controls. Linear regression models examined associations between CogState performance and symptom severity (SCAT and RPQ), within and across the 24-hour and one-week time points. Additional models evaluated whether combining 24-hour symptom severity assessments with CogState performance improved prediction of one-week symptom burden and symptomatic status. SCAT symptom severity demonstrated excellent discriminatory classification accuracy for SRC versus controls at 24-hours post-injury (AUC [95% CI]: 0.949 [0.916 - 0.981]). CogState task performance showed lower discriminatory accuracy but demonstrated fair classification and prognostic utility (e.g., Identification task AUC [95% CI]: 0.666 [0.582 - 0.750]). CogState performance at 24-hours was significantly associated with overall symptom severity at both 24-hours and one-week, as well as with symptom severity across individual symptom domains. In combined models, 24-hour symptom severity and CogState performance independently contributed to the prediction of symptomatic from asymptomatic individuals at one-week post-SRC (e.g., Identification task AUC [95% CI]: 0.721 [0.606 - 0.835] for classification based on <4 versus [&ge;]4 symptoms). These findings indicate that CogState performance at 24-hours post-SRC may serve as an objective adjunct to subjective symptom-based reporting, supporting both diagnosis and early prognostication in the clinical evaluation of SRC.

BackgroundSedentary behavior is highly prevalent following traumatic brain injury (TBI) and compounds existing risks for cardiovascular, neurodegenerative, and affective disorders. The cognitive and behavioral sequelae of TBI, including impaired decision-making, blunted reward processing, and cognitive fatigue, create particular barriers to adopting and maintaining an active lifestyle. Despite this, effective behavior change interventions targeting physical activity in community-dwelling TBI survivors remain scarce. Here, we evaluated the feasibility, compliance, and preliminary efficacy of a 12-week remotely delivered walking intervention combining planning, behavioral reminders, and monetary micro-incentives. MethodsFifty-six adults aged 40-80 years with a mild-to-moderate TBI diagnosed between 3 months and 15 years prior were randomized to either a planning, reminders, and micro-incentives intervention (n=23) or a health advice control condition (n=25). Participants wore a Fitbit Inspire 3 continuously throughout the study. Intervention participants completed weekly phone calls to plan five 30-minute walks for the following week, received daily text message or email reminders on planned walk days, and earned small monetary incentives upon walk completion. Control participants received weekly health education calls. Feasibility was assessed through recruitment, retention, and adverse event rates. Compliance was assessed via phone call completion rates and Fitbit wear time. Efficacy outcomes included weekly walk counts, walking duration, and step counts, modeled using Poisson generalized linear mixed models and linear mixed-effects models over 12 weeks. ResultsForty-eight participants completed the study (retention rate: 84.2%), with high phone call compliance in both groups (intervention: 98.4%; control: 98.1%). Intervention participants completed significantly more walks than controls from week 1 onward (aIRR = 5.33, 95% CI: 2.27-12.5, p < 0.001), with the group difference growing over time (interaction aIRR = 1.09 per week, 95% CI: 1.01-1.17, p = 0.029). Estimated marginal means indicated that intervention participants completed 5.5 times more walks than controls at week 1, increasing to 15.5 times more by week 12. The intervention group also walked significantly longer at week 1 (b = 62.14 min, 95% CI: 1.05-123.23, p = .046), with the advantage growing over time; by week 12, intervention participants walked 5.3 times longer than controls. Similarly, the intervention group accumulated significantly more steps during walks at week 1 (b = 4,779 steps, 95% CI: 45.50-9,513.00, p = .048), accumulating 3.1 times more steps than controls by week 12. ConclusionsA remotely delivered, multicomponent walking intervention targeting planning, behavioral reminders, and micro-incentives was feasible, well-tolerated, and produced meaningful increases in walking activity in community-dwelling adults with TBI. With high retention and compliance, and consistent effects on walk counts, duration, and steps across the intervention period, these findings provide compelling support for a larger, fully powered trial.

Executive dysfunction affects nearly 50% of individuals with traumatic brain injuries (TBI), yet interventions targeting the underlying neural mechanisms remain limited. This study examined whether aerobic exercise modulates functional connectivity to improve executive function in individuals with mild TBI and identified the neural pathways mediating these improvements. In this secondary analysis of a 12-week pilot randomized controlled trial, participants with mild TBI (n=24) were randomized to aerobic exercise (n=12) or active balance control (n=12). Resting-state fMRI with multivariate pattern analysis revealed that aerobic exercise selectively altered functional connectivity patterns of the anterior cingulate cortex (ACC) compared to balance control. Post-hoc seed-to-voxel analyses identified widespread ACC connectivity differences between groups post-intervention while controlling for baseline, across 19 cortical regions spanning default mode, frontoparietal control, and salience networks. Critically, greater anticorrelation between the ACC and insula following aerobic exercise was associated with improved Trail Making Test B-A performance in the aerobic group ({beta}=46.92, p=0.04) but not the balance group, indicating that participants who developed stronger ACC-insula functional segregation showed greater reductions in executive function completion times. These findings establish the ACC-insula circuit as a critical neural substrate mediating exercise-induced executive function recovery after TBI and identify this pathway as a promising therapeutic target for exercise-based rehabilitation interventions.

BackgroundAdapted dance is a promising rehabilitation intervention for physical and psychosocial impairments in people with chronic stroke. However, in-person attendance is hindered by limited community ambulation, transportation, and schedule conflicts. At-home participation with a live-streamed dance program could address these issues, but psychosocial benefits may be diminished because of reduced social interactions. The primary objective of this study was to assess the feasibility and safety of a live-streamed dance program for chronic stroke. Secondary objectives were to characterize participants who choose live-stream vs in-person options and quantify pre-post changes in balance, gait and social connection. MethodPeople with chronic stroke were given the choice of attending a live-streamed adapted dance program either in-person or at home twice a week for 4 weeks. A priori feasibility criteria were tracked, and participants were characterized with self-report (Center for Epidemiologic Studies Depression Scale; CES-D) and performance-based measures (e.g., Montreal Cognitive Assessment, Chedoke McMaster Assessment) at baseline. Pre-post measures of secondary outcomes included gait speed, Mini Balance Evaluation Systems Test (Mini-BESTest), Activities of Balance Confidence Scale (ABC), and Inclusion of Community in Self scale (ICS). Unpaired median/mean differences in baseline clinical presentation were used to compare in-person and live-stream participants. Paired median/mean differences were used to examine change in secondary outcomes with dance. ResultsInterest and enrollment rates for both groups combined were 87% and 38% respectively. Of the 13 people who enrolled, 8 chose in-person and 5 chose live-stream. In-person and live-stream attendance rates were 83% and 89% respectively, and retention rates were 80% and 75% respectively. At baseline, the in-person group had greater depressive symptoms (CES-D score, median [IQR] difference: 11.5 [-21.5, -5]), and faster mean gait speed (-25.8cm/s [-50.98, 0.006]) than the live-stream group. There were no pre-post changes in secondary outcome measures. ConclusionsA live-streamed dance intervention featuring in-class and at-home participation is safe and feasible for people with chronic stroke. These results will inform a future randomized controlled trial to investigate the effects of a live-stream dance program with a longer duration while considering how factors such as gait function and mood may relate to the choice between in-person and at-home attendance.

BackgroundDespite recommendations in clinical guidelines, clinical experience indicates that engagement with splints and orthotics varies amongst people after stroke. ObjectivesThe aim of the study was to understand the factors that influence engagement with splints and orthotics in people after stroke. MethodsPeople after stroke who had been wearing a splint or orthotic (also known as devices) for at least 2 months under the care of one Community Neurosciences Team in the UKs National Health Service were included. Semi structured interviews based on the constructs of Banduras Social Cognitive Theory (SCT) were used to gather participants views, and a framework analysis applying the constructs of SCT was completed using NVIVO software. ResultsFour key themes were identified: 1. Self-Regulation; difficulties applying the device and aesthetic acceptability. 2. Self-Efficacy; increased confidence when wearing the device and reduced motivation to wear the device. 3. Outcomes Expectation; reduced falls risk, improved gait, improved balance, maintaining range of movement, and negative effects such as discomfort, pain, itching. 4. Social Support; support needed to apply the device and the burden on family members/carers to apply the device correctly. ConclusionsThe findings of this study highlight key factors that influence engagement with orthotics and splints. These include difficulty applying the device after stroke, device aesthetics, comfort, and the importance of continued support from carers. Manufacturers should consider how people after stroke can independently don and doff devices. Education of carers and family members also appears key to support their engagement.

BackgroundPeople with hip or knee joint arthroplasties are commonly advised to avoid high-impact physical activities, despite increasing demand to return to sport and vigorous exercise. Current implant testing standards do not reflect real-world loading during high-impact tasks, and few studies have quantified implant loads in high-functioning individuals who have returned to such activities. MethodsHigh-functioning adults with a total hip arthroplasty (THA, n = 11), total knee arthroplasty (TKA, n = 4), or unicompartmental knee arthroplasty (UKA, n = 3) performed a range of low-to high-impact activities, including walking, running, hopping, countermovement jumps, landings, and change-of-direction tasks. Three-dimensional trunk and lower-limb kinematics and ground reaction forces were collected. Musculoskeletal modelling was used to quantify three-dimensional hip and knee joint contact forces. Linear mixed-effects models were used to rank implant loads across activities and to compare peak resultant joint loads with healthy controls from a prior study. ResultsFor people with THR, relative to walking, a 45{degrees} change of direction generated the highest predicted hip contact force (8.38 BW, 95% CI 7.70-9.06), followed by running and unilateral hopping (all >1.5x walking, p < 0.05). Unilateral hopping and running produced the highest predicted knee contact force in TKA and UKA participants (8.0-9.1 BW), and both significantly greater than walking (p < 0.05). Compared with healthy controls, THA participants exhibited a lower predicted HCF during walking (-1.58 BW, 95% CI -2.46 to -0.69), but no group differences were observed for running, hopping, or jumping. ConclusionHigh-impact activities vary widely in model-estimated hip and knee contact forces. Several tasks were not substantially higher than walking. These data provide a biomechanical basis for evidence-informed activity prescription, regulatory implant testing, and future computational simulation of implant performance under realistic loading conditions.

Background: Quadriceps weakness may reduce sagittal plane shock absorption during landing, shifting load toward the frontal plane and increasing knee abduction moment (KAM), a biomechanical risk factor for anterior cruciate ligament (ACL) injuries. Purpose: The purpose of this study was to evaluate the association between isokinetic quadriceps strength and peak KAM during drop vertical jump landing in adolescent athletes. Study Design: Secondary analysis of previously collected data. Methods: Healthy adolescent athletes completed quadriceps strength testing using an isokinetic dynamometer and a biomechanical assessment during a drop vertical jump task. Quadriceps strength was quantified as peak concentric torque and the peak external KAM was calculated during the landing phase on the dominant limb. Both strength and KAM were normalized to body mass. Linear regression was used to examine the association between normalized quadriceps strength and peak external KAM on the dominant limb. Results: The association between quadriceps strength and peak normalized KAM on the dominant limb was not statistically significant ({beta} = -0.053 (95% CI [-0.137 to 0.030]), F(1,119) = 1.62, R2 = 0.013, p = 0.206). Quadriceps strength explained only 1.3% of the variance in peak KAM, indicating a negligible association between these variables in this cohort. Discussion: Quadriceps strength was not associated with peak normalized KAM during landing, suggesting that frontal-plane knee loading during a drop vertical jump is not meaningfully explained by maximal concentric quadriceps strength alone. KAM appears to be driven more by multi-joint movement strategy and neuromuscular coordination than by the capacity of a single muscle group.

Centre of mass (COM) is a key measurement used to assess balance and mobility. Marker-based motion capture systems have traditionally been used to measure COM, but they are time-consuming and prone to marker error. Markerless motion capture systems offer a potential alternative, reducing setup time while maintaining accuracy. The ease of collecting markerless data may be particularly beneficial when study participants have limited mobility, such as those with stroke. This study aimed to determine the differences in COM measurements between marker-based and markerless motion capture systems during balance and mobility tasks in individuals with sub-acute stroke. Seventeen participants completed the following tasks: walking, quiet standing, sit-to-stand, rise on toes, and backward reactive stepping. COM data were analyzed using two markerless models, a default with 17 segments and a fit model with 11 segments to match the marker-based model to be compared as the reference. The results showed high correlations (R2 = 0.75 to 0.999) and low root-mean-square differences (< 2 cm) in the anterior-posterior and medial-lateral directions. Larger differences (> 4 cm) were observed in the superior-inferior direction, particularly with the default model. These findings suggest that markerless motion capture can be used to measure COM in people with stroke, and that model selection plays an important role in COM estimates.

ContextClinical assessments of landing mechanics often require complex scoring systems or laboratory-based motion analysis, which can limit feasibility in routine practice. A visually based landing-mechanics score centered on a standardized optimal joint-alignment configuration ("Zero Position") may offer a simple, clinically deployable alternative. ObjectiveTo determine the intra- and inter-rater reliability of a landing mechanics score based on standardized optimal joint alignment at the moment of maximal center-of-mass (COM) descent. DesignCross-sectional reliability study. SettingUniversity athletic training facility. Patients or Other ParticipantsNinety healthy male collegiate athletes. Main Outcome MeasuresLanding mechanics were evaluated using frontal- and sagittal-plane video recordings, with scoring performed on the frame corresponding to maximal COM descent. Five criteria reflecting the standardized joint configuration ("Zero Position") were assessed. Intra- and inter-rater reliability were calculated using Cohens kappa coefficients and Kendalls W. ResultsAll five criteria demonstrated moderate to substantial intra-rater reliability and moderate to almost perfect inter-rater reliability. The total landing-mechanics score showed excellent agreement across all comparisons. The scoring system required minimal training and was feasible to implement using standard video recordings. ConclusionsThe landing-mechanics score centered on the Zero Position demonstrated high reliability and strong clinical feasibility. This simple, visually grounded assessment may support routine clinical screening, injury-risk evaluation, and return-to-sport decision-making. Future research should examine its applicability to single-leg landings and sport-specific high-risk movements.

BACKGROUNDFall injuries in older adults are devastating and often caused by impaired reactive balance to unexpected trips and slips, which conventional exercise programs do not target. This study examined whether a low-dose perturbation balance training (PBT) program among older adults can improve balance recovery following trips and slips and reduce falls and fall injuries. METHODS111 older adults (65+ years) were randomised into an intervention or control group. The intervention group undertook one weekly PBT session for three weeks on the Trip and Slip Walkway, followed by three-monthly PBT booster sessions over one year, for a total of six sessions. The control group received an educational booklet. Blinded staff assessed laboratory-falls induced by a trip and slip with a safety harness at baseline and one year. Number of falls and fall injuries in daily life were collected weekly for one year. RESULTSCompared to the control group, the intervention group experienced a 26% reduction in laboratory falls at 12 months (RR = 0.74; 95% CI: 0.54, 0.99; P = .040) but not different in number of falls, trip-and slip-encounters in daily life. However, fall-related injuries were reduced by 57% (rate ratio = 0.43; 95% CI: 0.19, 0.94, P = .024) over one year. A reduction in falls occurred within the first three months, with greater benefit among participants who completed at least three training sessions. CONCLUSIONSA low-dose PBT program can improve reactive balance over 12 months and reduced injurious falls by 57%, with benefits likely due to enhanced reactive balance rather than proactive gait strategies. Older adults may require at least three sessions to achieve meaningful fall reduction, with periodic booster sessions to sustain benefits. Incorporating PBT into exercise programs may enhance their efficacy in preventing falls and fall injuries in daily life. Key PointsA low-dose perturbation-based training program (six sessions over 12 months) improved reactive balance at 12 months and reduced injurious falls by 57%. Benefits are likely due to task-specific improvements in reactive balance against trips and slips rather than proactive gait strategies or other risk factors. Incorporating PBT into exercise programs may improve their efficacy in preventing falls and fall injuries in daily life. Why does this paper matter?Falls are the leading cause of injury-related hospitalization and loss of independence in older adults. By targeting reactive balance--an ability neglected by conventional exercise programs--it offers a novel, evidence-based approach to enhance fall prevention and reduce injuries.

Repetitive head impacts (RHI) from contact and collision sports have been associated with later-life cognitive and neurobehavioral impairments, as well as neurodegenerative conditions such as chronic traumatic encephalopathy (CTE). RHI-associated clinical sequelae among female former soccer players, specifically, are not well understood. This cross-sectional study aimed to examine the relationship of RHI exposure proxies (e.g., total years of soccer play, highest level of play, and estimated cumulative heading frequency) with clinical measures (e.g., subjective cognitive complaints, objective cognitive performance, behavioral dysregulations, and depressive symptoms) among 3,174 women, aged 40 years or above, enrolled in the Head Impact and Trauma Surveillance Study (HITSS), all of whom played organized soccer. HITSS participants completed an online battery that elicited self-reported cognitive and behavioral complaints and depressive symptoms, and that assessed cognitive performing via computerized tests. Multivariable linear and logistic regression models estimated associations between soccer-related RHI proxies and outcome measures, adjusting for age and education. Among the former soccer players, longer duration of soccer play, higher level of play, and greater estimated cumulative heading frequency were significantly associated with worse self-reported cognitive functioning, greater behavioral dysregulation, and elevated depressive symptom severity (range of significant unstandardized B coefficients: 0.02 to 0.52). Higher estimated cumulative heading exposure was associated with higher odds of clinically meaningful elevations on subjective measures (OR range: 1.05 to 1.13) There were no associations between any of the RHI proxies and performance on the objective computerized cognitive assessments. Among middle-aged women who played organized soccer, cumulative RHI exposure was associated with small but statistically significant effects for measures of subjective cognitive complaints, behavioral functioning, and depressive symptoms. We found no associations for objective outcomes of cognitive function. Continued monitoring of this large cohort of female former soccer players will improve understanding of long-term consequences of soccer play.

BackgroundIn critically ill patients admitted to the intensive care unit (ICU), rapid skeletal muscle atrophy frequently develops in the acute phase. This ICU-acquired weakness can significantly impair long-term physical function. Although the biceps brachii cross-sectional area (CSA) is commonly used to assess muscle atrophy, its ultrasound imaging can be technically challenging, and the flexor carpi ulnaris may offer a more accessible alternative. Therefore, this study aimed to investigate whether CSA changes of the flexor carpi ulnaris correlate with those of the biceps brachii in critically ill patients admitted to the ICU, as well as whether the flexor carpi ulnaris CSA reflects systemic muscle atrophy in the acute phase of the ICU stay. MethodsTwenty critically ill patients admitted to the ICU underwent serial ultrasound assessment of the biceps brachii and flexor carpi ulnaris CSAs on days 0, 5, 7, and 14 after admission. Longitudinal changes in CSA were analyzed using the Friedman and Wilcoxon signed-rank tests. Correlations between the biceps brachii and flexor carpi ulnaris were examined using Spearmans rank correlation, and structural equation modeling was applied to explore causal relationships between clinical variables and CSA changes. ResultsSignificant CSA reductions were observed in both the flexor carpi ulnaris (-20.6%) and biceps brachii (-16.3%) by day 14, and the relative CSA changes of the biceps brachii and flexor carpi ulnaris showed a moderate positive correlation ({rho} = 0.5489, p = 0.0122). Structural equation modeling analysis revealed that the biceps brachii CSA change had positive effect on that of the flexor carpi ulnaris ({beta} = 0.249, p = 0.0011). Moreover, body mass index was positively associated with the baseline flexor carpi ulnaris CSA ({beta} = 0.042, p = 0.0004). However, the baseline flexor carpi ulnaris CSA was not a significant predictor of subsequent CSA changes. ConclusionUltrasound measurement of the flexor carpi ulnaris CSA offers a practical alternative to that of the biceps brachii for early detection of muscle wasting in ICU patients. Given its anatomical accessibility and high sensitivity to early atrophic changes, it may serve as a feasible screening tool for ICU-acquired weakness and inform timely interventions.

PurposeRobotic walkers are a new and novel technology with growing evidence of benefits for children living with mobility impairments. However, little is known about how using these devices at home impacts families. This study aims to explore parents perceptions of home-based robotic walking and the impacts on their family and their child living with a mobility impairment. Materials and MethodsQualitative interviews were conducted with seven parents who have a child who used a robotic walker in their home for at least six months. Thematic analysis was used to analyze all interviews. Themes were then mapped to the F-words for child development. ResultsUsing a robotic walker at home led to family bonding and created new ways for parents and siblings to interact with the child living with a mobility impairment. Many children enjoyed using the robotic walker. This, combined with being able to direct its use in their own environments, contributed to less parental stress than was associated with other rehabilitation interventions. However, some parents discussed an increase in parental stress due to certain logistical aspects, getting their child in and out and transporting the robotic walker. Finally, parents discussed that obtaining the device was a financial burden for them. ConclusionRobotic walking in the home environment impacts family relationships and parental stress. Understanding families experiences can inform decision-making by families and practitioners around the appropriateness of robotic walker use for a child living with a disability.

Background: Psychological readiness to return to sport and subjective knee function are critical outcomes following ACL reconstruction (ACLR), yet they do not always progress in parallel. An athlete may demonstrate high subjective knee function but low psychological readiness, suggesting a mental barrier to return, or conversely, report high readiness despite persistent functional limitations, raising concerns of overconfidence and reinjury risk. Understanding how these domains change together during recovery is essential for identifying mismatches that may require targeted intervention. Purpose: The purpose of this study is to examine the relationship between changes in psychological readiness (ACL-RSI) and subjective knee function (IKDC) from early to late recovery following ACLR. Study Design: Secondary analysis of prospectively collected data. Methods: Athletes (N = 48, Age at ACLR = 17.7 {+/-} 1.8 y) aged 15-25 years who underwent ACLR with an ipsilateral autograft, had a pre-injury MARX score > 8, and completed the ACL-RSI and IKDC questionnaires at 3.5 {+/-} 1 and 7 {+/-} 1 months post-ACLR were included. Percent changes in ACL-RSI and IKDC scores between early and late recovery were calculated. Spearman's rank correlation was used to examine the association between changes in psychological readiness and subjective knee function. Significance was set to p < .05. Results: The mean percent change in ACL-RSI was 40.7 {+/-} 57.1% and the mean percent change in IKDC was 24.8 {+/-} 18.1% from 3.5 {+/-} 1 months to 7 {+/-} 1 months post-ACLR. The percent changes in ACL-RSI and IKDC scores from 3.5 {+/-} 1 months to 7 {+/-} 1 months post-ACLR were moderately correlated ({rho} = 0.350 (95% CI [0.089, 0.584]), p = 0.012). Discussion: The main finding of this study was that subjective knee function and psychological readiness to return to sport changed in parallel from 3.5 to 7 months following ACLR. Clinicians can use this information regarding the concordant progression of psychological readiness to return to sport and subjective knee function to personalize ACL rehabilitation for future patients. Overall, clinicians can understand that if psychological readiness improves, subjective knee function will likely improve over the 3.5- to 7-month post-ACLR time frame, and vice versa. Therefore, focusing on both of these components at multiple time points during the recovery process may be influential to ensure the greatest likelihood of returning to sport in athletes following ACLR.

Purpose: Human anatomy remains foundational to clinical practice, yet reduced instructional hours raise concerns about graduate competence and preparedness for patient care. Although trainees often report confidence, supervisors may perceive deficiencies, creating a gap between self-assessment and external evaluation. This study examined stakeholder perspectives on anatomical competence within physical therapy education to identify areas of discordance in perceived capability. Methods: A cross-sectional web-based survey collected responses from 165 stakeholders associated with an entry-level Doctor of Physical Therapy program featuring a 16-week dissection curriculum. Participants rated four domains of anatomical competence using a 5-point ordinal scale. Group differences were analyzed with the Kruskal-Wallis test appropriate for ordinal data. This methodology ensured robust assessment of stakeholder perceptions and comparative analysis. Results: Median ratings of preparedness and capability were 4 of 5 (quite prepared). Significant discordance emerged in three domains: recent graduates rated their foundational knowledge and ability to explain complex concepts to lay audiences higher than faculty or clinical instructors, whereas faculty expressed lower confidence in graduates' ability to explain patient symptoms using anatomical principles. No significant differences were observed in the ability to describe structures by location, suggesting shared perceptions of basic anatomical understanding despite variation in applied reasoning. Conclusions: Stakeholders generally viewed graduates as well prepared, yet disagreement persisted regarding clinical application of anatomical knowledge. Faculty skepticism about symptom explanation indicates that mastery of anatomy alone does not guarantee clinical reasoning. Curricular strategies emphasizing vertical integration and explicit connections between anatomical science and patient-centered reasoning may help bridge perception gaps and enhance professional competence.

BackgroundReactive balance training using repeated perturbations may reduce falls, however, training methods are not easily replicated or translatable to clinical settings. This study aimed to examine the effects of a novel reactive balance training program on balance recovery from laboratory induced trips and slips and fall risk factors in older people using simple and low-cost equipment. MethodsWe conducted a randomised controlled trial involving 88 older people. An intervention group (n = 43) received the ReacStep program which involved tether-release reactive stepping and intentional slips once a week for 6 weeks. Both the intervention and control (n = 45) groups received home-based strength training for 8 weeks. Blinded staff assessed reactive balance (laboratory induced falls), physical functions at baseline (week 1) and post intervention (week 8). Weekly SMS surveys ascertained falls in daily life over 12 months. ResultsBoth groups were comparable in demographics, with a mean age of 72 years (SD = 5.6). Adherence to ReacStep sessions was high (90%). There were no significant differences between groups in laboratory-assessed reactive balance falls at post-test or daily-life falls over one year (P =.19). However, at post-test, the intervention group demonstrated significant improvements in usual gait speed, maximum step length, and choice stepping reaction time compared to controls (P <.05). ConclusionsThe ReacStep program demonstrated excellent adherence, was well tolerated, and improved gait parameters required for balance recovery following postural perturbations in older people. Nevertheless, it appears this program is not sufficient to improve reactive balance against unexpected trips and slips. Key pointsO_LIThe ReacStep program is acceptable, demonstrates excellent adherence and improves gait measures in older people, potentially reducing fall risk. C_LIO_LIThe generalisability against unexpected trips, and slips, and falls in daily life may be limited. C_LIO_LIFuture research should explore more ecological perturbations while maintaining its accessibility and acceptability. C_LI

Objectives: Compare Anterior Cruciate Ligament (ACL) Return to Sport after Injury (ACL-RSI) scores over time following ACL reconstruction (ACLR) between male and female patients aged 15 to 25 years with primary ACL injuries and ACL reinjuries. Design: Retrospective cohort design. Setting: Sports physical therapy clinics. Participants: 332 patients aged 15-25 years who underwent ACLR following either primary ACL injury or ACL reinjury, either contralateral or ipsilateral graft reinjury, and had at least one observation of the ACL-RSI. Main Outcome Measures: ACL-RSI score. Results: ACL-RSI scores significantly increased over time post- ACLR (p < .001), males reported significantly higher scores compared to females (p < .001), and patients with contralateral ACL reinjury demonstrated higher scores than those with ipsilateral ACL graft reinjury (p = .006), though there was no difference in scores between patients with primary ACL injury and ACL reinjury. A significant interaction effect of sex and injury status was also observed (p = .009), generally demonstrating that females had lower psychological readiness compared to males across injury statuses. Conclusions: ACL-RSI following ACLR varies based on biological sex and time post-ACLR, though ACL reinjury, independent of the reinjured leg, does not appear to effect scores compared to primary ACL injury.

BackgroundThoracic spine mobilization (TSM) has been proposed to influence autonomic nervous system (ANS) activity, yet evidence remains inconsistent and feasibility of standardised protocols is unclear. This study aimed to evaluate whether a randomized TSM protocol can be implemented successfully in healthy participants and to provide preliminary estimates of its effects on heart rate variability (HRV) and heart rate (HR). MethodsA randomized feasibility trial was conducted with healthy young adults receiving six manual therapy sessions consisting of rotational mobilizations above Th5 over 14 days. Feasibility outcomes included adherence, absence of unexpected adverse events (UAE), and practicality of autonomic data acquisition. Physiological outcomes comprised HRV parameters, high-frequency (HF), low-frequency/high-frequency ratio (LF/HF) and HR, analyzed using autoregressive (AR) and fast Fourier transform (FFT) methods. ResultsProcedural safety and methodological integrity were confirmed (no UAE; complete datasets), but feasibility was only partially achieved due to adherence shortfalls, higher attrition, and device-related delays. Physiologically, large effect sizes were observed in the intervention group: at evening assessment, HF_AR showed ES = 0.80 (p = .008); at morning assessment, HF_FFT ES = 0.72 (p = .016), HF_AR ES = 0.78 (p = .010), and LF/HF_AR ES = 0.70 (p = .021). HR remained unchanged. These findings suggest repeated TSM may modulate HRV, primarily through HF-related changes associated with vagal activity, while LF/HF interpretation remains controversial. ConclusionA randomized TSM protocol is safe and methodologically viable with logistical refinements. Preliminary evidence indicates potential vagal modulation, warranting larger trials with respiratory control, ECG-based HRV, multimodal ANS measures, and clinical populations to confirm efficacy and translational relevance.

ImportancePrognosticating functional independence after an acute stroke is critical for anticipatory guidance and rehabilitation planning. Here we demonstrate that poor brain health at the time of incident stroke is linked to worse functional outcomes for women compared to men. ObjectiveTo determine if brain health at time of stroke presentation has a differential effect on functional outcomes between men and women. DesignRetrospective cross-sectional study. SettingAnalysis conducted in 2025 with multi-center patient data that included participants from two large acute ischemic stroke cohorts; local (GASROS) and multinational (MRI-GENIE) between the years 2003 and 2011. ParticipantsClinical data collected for enrolled study participants included demographic data, medical history of hypertension, diabetes mellitus, hyperlipidemia, smoking status, acute stroke severity as measured by National Institutes of Health Stroke Scale (NIHSS), stroke etiology, and modified Rankin Scale (mRS) score at 90 days post-stroke. Brain health was quantified as effective reserve derived from acute neuroimaging data. Exposure(s)designated sex, retrieved from registration records. Main OutcomeFunctional outcome was measured by mRS scores at 90 days post-stroke, in men and women with poor, moderate, or good brain health at time of stroke injury. ResultsA total of 1039 patients were included in the analysis, 37.8 % women, median age 67 [interquartile range 56-77]. Women with poor brain health (i.e. lowest quartile of effective reserve) had worse functional outcomes at 90 days (55.6% with mRS>2) compared to men with poor brain health (31.2% with mRS>2: p < 0.001). This difference between men and women was not observed in categories of moderate or good brain health. There was no observed significant difference in stroke severity, volume of acute lesion, burden of white matter hyperintensities, or stroke etiology between men and women with poor brain health. Conclusions and RelevanceBrain health at the time of incident stroke has a differential effect on functional outcomes at 90 days between men and women. Women with poor brain health endure disproportionately worse outcomes compared to men. This highlights an important step in understanding sex-specific vulnerability in early recovery post-stroke, and can inform disposition, rehabilitation services, and resource allocation planning.
