Abstract
Parkinson’s disease is the three universal concomitants of human aging and major cause of morbidity among the elderly. It’s characterized by the predominant degeneration of dopaminergic neurons in the substantia nigra pars compacta, eventually leading to altered mechanics and control of the whole body during functional activities of daily living, such as quiet standing, level walking, obstacle crossing. Owing to the limitation of sensitivity of clinical functional activities assessment tools, it remains unclear as to how the progress of movement deviation of Parkinson’s disease affects the control and coordination of the joints on the performance of activities of daily living. Motion data including quiet standing, level walking and obstacle-crossing were measured using a three-dimensional computerized motion analysis system equipped with 6 ultra-high resolution infrared cameras and 2 force plates. In the 1st grade of patients, there were greater ankle eversion and knee flexion angle on affected side during the stance phase of gait cycle. There was lesser hip abduction angle on un-affected side during terminal stance phase. Greater hip abductor, hip flexor and knee flexor moment was compensated on un-affected side. These deviations of motor were maybe used to detect in early stage. There were significantly greater COM-COP inclination angle on affected side during crossing. After taking mediation, the 2nd-3rd stage of patients perform greater sway area and medial-lateral side displacement during quiet standing. There was greater motor deviation but lesser coordination deviation than before taking mediation. The motor deviation progression was similar with the 1st stage of patients. The muscle strengthening of hip abductor, hip flexor and knee flexor and balance training maybe was important in both groups.
