Multisystem Balance Training Reduces Injurious Fall Risk in Parkinson Disease: A Randomized Trial

Previous studies have shown that balance training could reduce falls in people with Parkinson disease. However, it remains unclear whether exercise can reduce injurious falls. The objective of present study was to determine whether multisystem balance training could reduce injurious falls and modify targeted fall risk factors in Parkinson disease nonfallers and single fallers. Participants were randomly assigned to an 8-wk balance group (experimental, n = 41) or an upper limbs group (control, n = 43). Outcomes examined at posttraining and 12-mo follow-up were: (1) injurious fall risk (ratio of noninjurious fallers to injurious fallers); (2) two potential fall risk factors based on Balance Evaluation Systems Test scores and dual-task timed-up-and-go times. At posttraining, results indicated that there were no injurious falls, and fewer experimental participants were found in high fall risk cohorts based on Balance Evaluation Systems Test scores and dual-task timed-up-and-go times (P
