Gym-Based Modified Powerlifting Exercises for People with Early Onset Parkinsons Disease: Study Protocol

BackgroundAlthough powerlifting has been shown to increase strength and function in some adults, the safety and feasibility of powerlifting exercises modified for people with early onset Parkinsons disease is not known. MethodsPeople with early onset Parkinsons disease (age <50 years) will be invited to engage in eight consecutive weeks of twice-weekly modified powerlifting exercises in a community gymnasium. The primary outcome is the feasibility of powerlifting exercises modified for people with early onset Parkinsons disease, quantified by measures of safety, adverse events, adherence, access, and cost. Secondary outcomes include motor disability, quality of life, psychosocial status, and strength. Semi-structured interviews with participants and exercise trainers will capture experiences, beliefs, and attitudes towards this type of community-based strength training. DiscussionPowerlifting may be beneficial for those with early onset Parkinsons disease as it can improve muscle strength, coordination, and balance, and may have neuroprotective effects, potentially slowing down the progression of the disease. However, there is a need to first measure feasibility and safety of modified powerlifting in a small number of individuals before the efficacy can be tested in larger randomised controlled trials. Ethics and disseminationWe will publish the findings in peer-reviewed journals and presentations at conferences. The consumer engagement council will guide communication of findings to individuals with early onset Parkinsons disease, ensuring information is accessible and actionable for the target audience.
