The paper presents a comparative study of the kinematic parameters of the upper limbs of one healthy subject and one patient with lateral distal humerus implant. This study aims to identify the movement patterns of the upper limb joints, having a particular interest in elbow joint, due to the patients pathology. Both subjects have been recorded in identical conditions, performing the same exercise what simulates one of the common daily activities. The kinematic parameters which have been analyzed were flexion-extension and abduction-adduction in shoulder joint and flexion-extension of the elbow joint. The joint angles have been averaged per each valid trial and exercise. The comparison of the joint angle variation was performed in terms of normalized time. Standard deviation was computed to evaluate the variability of joint angles. Movement symmetry between left and right arms was evaluated by computing the p-values of the averaged series.
