Effect of real-time feedback-based core stabilization training using a sling on balance and gait in patients with stroke: Randomized Controlled Trial

BackgroundBalance impairments commonly occur in patients after stroke. Research is warranted to improve the efficiency of rehabilitation by combining core stabilization training, such as trunk exercises, and real-time feedback. This study aimed to evaluate the effect of real-time feedback-based core stabilization training (RFCST) using a sling on the dynamic balance and gait of patients with stroke. MethodsThirty-eight patients with stroke were randomly assigned to either RFCST using a sling group (n= 19) or a control group (n= 19). Each group was trained for 30 min daily, 3 times a week for 4 weeks. The Trunk Impairment Scale (TIS), Functional Reach Test (FRT), Postural Assessment Scale for Stroke (PASS), Timed Up and Go (TUG) test, and gait parameters were assessed using the GAITRite system before and after the intervention. ResultsThe results showed a significant interaction between Group*Time effect F(1, 36)= 36.068, p<0.001, {eta}{superscript 2}p= 0.5 in TIS; F(1, 36)= 63.890, p<0.001, {eta}{superscript 2}p= 0.640 in FRT; F(1, 36)= 89.283, p<0.001, {eta}{superscript 2}p= 0.713 in PASS, F(1, 36)= 150.893, p<0.001, {eta}{superscript 2}p= 0.807 in TUG; F(1, 36)= 27.275, p<0.001, {eta}{superscript 2}p= 0.431 in gait velocity; F(1, 36)= 54.401, p<0.001, {eta}{superscript 2}p= 0.447 in cadence; F(1, 36)= 5.601, p=0.023, {eta}{superscript 2}p= 0.135 in step length; F(1, 36)= 22.559, p<0.001, {eta}{superscript 2}p = 0.385 in stride length; F(1, 36)= 15.516, p<0.001, {eta}{superscript 2}p = 0.301 in swing phase rate; and F(1, 36)= 28.451, p<0.001, {eta}{superscript 2}p = 0.441 in stance phase rate. ConclusionBased on these results, it can be concluded that RFCST using a sling can improve dynamic balance and gait parameters in patients with stroke.
