Abstract
Recurrent falls are common in persons with Parkinson disease (PD), and a decrease in lower extremity (LE) power is predictive of falls in the general population of older adults. To date, we are unaware of a synthesis of the literature pertaining to power training, postural stability, and falls in persons with PD. This narrative review synthesizes current literature related to the effect of LE power training on postural stability and falls in older adults with PD. There is limited yet compelling evidence to support an association between LE power and the performance of balance and mobility tasks in persons with PD. A need for further research is indicated to determine the strength of the relationship between improved power output, LE power symmetry, and falls reduction in individuals with PD.
