Overview
The main signs of Parkinson’s disease include balance disorders, which are associated with a high risk of fall and injuries. The order and muscle activation patterns in these patients in postural-demanding conditions have not been sufficiently clarified yet. We therefore investigated the muscle activation patterns during the transition from bipedal to unipedal stance in a group of patients with Parkinson’s disease and in a control group using surface electromyography (sEMG). Our objective was to determine, whether the activation order differs between the two groups and whether the findings depend on the degree of elevation of the lifted extremity. The secondary objective was to determine, whether sEMG findings on the preferred (dominant) and non-preferred extremity differ. The observed differences between the two groups included muscle activation patterns as well as changes related to the extent of elevation of the lifted leg and differences between the muscle activation order on the preferred (dominant) and non-preferred leg.
