Abstract
Drop foot often happens during hemiplegics walk because the muscle groups are too weak to contract. Throughout analyzing the kinematic parameters on three anatomical planes with two walking speeds, this thesis aims at exploring the relationship between the upper and the lower limb in terms of displacement, velocity, acceleration, angle, angular velocity, and angular acceleration. The extreme-valued points chosen from the above mentioned kinematic parameters could be used as inputs and outputs. Inputs and outputs are assessed in different stages of one gait cycle. The result can be used for future FES feedback control by receiving signals from the upper limb and stimulating the drop foot.
The Kinematic data of the upper and lower limb are collected by Visualeyez™ System during one gait cycle divided into nine stages. The kinematic parameters of the upper limb are used as inputs, and the angular variation in ankles of the normal and the paraplegic is regarded as the output. Subjects are five normals and three hemiplegics who move with normal and the fastest walking speeds. Kinematic parameters recorded by data VZ4000 cameras are analyzed with MATLAB software. The results show that extreme-valued points and zero-valued points appear regularly and shift about 7% for different subjects.
