Age- and Parkinson-related differences in trunk and lower-limb muscle activation during four balance tasks: A case-control pilot study.

Background: Poor postural control has been reported in people with Parkinson's disease, which could be explained by the changes in muscular activation patterns related to antigravitational muscles. This study aims to measure the muscle activation of antigravitational muscles during balance tasks in individuals, with and without Parkinson's.

Methods: Sixteen (16) participants (9 with Parkinson's), aged ≥65 yrs.
