The effect of gym training on multiple outcomes in Parkinson's disease: a pilot randomised waiting-list controlled trial.

There is accumulating evidence for the benefits of exercise in Parkinson's disease (PD), but less is known about group exercise interventions. We evaluated the effect of gym-training programme on people with PD. Thirty-two adults with mild to moderate PD, not currently exercising formally, were randomised to an immediate 20-week biweekly gym training programme at a local leisure complex, or a 10-week programme starting 10 weeks later. Assessments at baseline (T1), 10 weeks (T2) and 20 weeks (T3) included reaction time, motor performance (UPDRS), quality of life and illness perceptions. Experiences of the programme were assessed via questionnaire and a focus group. Overall UPDRS motor function score did not change over time. However, gym training was associated with significant improvements in reaction times and some timed tests in the immediate training group (T1-T2). The delayed group showed similar improvements following gym training (T2-T3). Participants reported enjoyment, obtaining social benefits, and increased confidence. However, the questionnaire measures did not show improvements in subjective health ratings or illness perceptions. Although benefits were not apparent in the questionnaire measures or overall UPDRS scores, our findings suggest that a 10-week gym training programme in a community setting can provide some benefits for people with PD.
