Parkinson's disease (PD) is a progressive neurodegenerative disease with common symptoms of gait disturbance and postural dysfunction
The cycle of repetitive motion in the gait is defined as the gait cycle
They have low gastrocnemius activity during the stance phase, their ability to regulate activation patterns is reduced, and their activity is unstable
The study recruited 72 participants: 24 early-stage PD patients, 24 healthy elderly (HOA) and 24 healthy young people (HYA)
PD and HOA subjects, PD and HYA subjects, HOA and HYA subjects in the gait cycle phased electromyogram
Two complete gait cycles were studied for each participant
During horizontal straight walking, the co-activation of PD patients increased significantly, and the TA activation decreased
For Parkinson's disease patients, the average postural instability and gait disorder (PIGD) score of the Gait Disorder Scale is lower = 5.
Scatter plot between MI-TA and clinical features
Consistent with the literature, it can be intuitively observed from the surface EMG that the age-matched control group showed greater TA activation in the intermediate stage, while the TA activation of Parkinson's disease patients decreased during the standing posture
The age-matched control group showed greater TA activation during the intermediate phase, while Parkinson's disease patients had decreased TA activation during the standing posture
