Intrapersonal and interpersonal evaluation of upper extremity kinematics.

Background: The quality of upper extremity (UE) function can be evaluated by measuring the kinematic parameters of patient movements.

Objective: This investigation focused on finding the angles and angular velocity amplitudes of UE motions in healthy participants to compare with the experimental results of patients with a UE disability who are trying to recover previous movement conditions.

Methods: The UE motions of 23 healthy adult volunteers were tested using a three-dimensional motion capture system and measuring hand segment motions.
