The gait kinematics for Parkinson's disease (PD) are usually examined in the time domain and limited to selected points on motion-time graphs. Wavelet analysis allows the examination of the whole waveform and demonstrates a high potential to assess the effects of PD treatment. The purpose of this study was to investigate whether differences existed in gait complexity and the frequency content of foot...
Patients with Parkinson's disease have symptom of walking disorders which can be alleviated by surgery. By evaluating gait kinematics, the effect of medical treatment can be quantitatively assessed. In this paper, a method using image markers based on rigid body was introduced to set markers on anatomy key points of human lower limbs, which efficiently reduced the measurement errors coming from the...
