Amputees often choose not to wear prostheses due to marginal performance or may settle for a prosthesis that offers only cosmetic improvement, but lacks function. A simulation tool consisting of a robotics-based human body model (RHBM) to predict functional motions, and integrated modules for aid in prescription, training, comparative study, and determination of design parameters of upper extremity prostheses will be developed.
The main objective of collecting and analyzing human movement during several common tasks is to optimize and validate the robotics based human model. The range of motion data of subjects performing activities of daily living such as opening a door, turning a wheel, grooming, eating, bilateral lifting, as well as recreational and sport activities such as swinging a baseball bat, and golf club will be analyzed. This motion analysis data will also be used to compare data between four groups: a control group (n=10), a braced group simulating prosthesis use (n=10), a group wearing a transradial prosthesis (n=10) and a group wearing a transhumeral prosthesis (n =10).

- Shoulder angle [ Time Frame: During task completion ]The shoulder angle (rotation, flexion/extension and abduction/adduction) will be measured during several tasks during one 3-4 hour testing period.
- Elbow angle [ Time Frame: During task completion ]The elbow angle ( flexion/extension and forearm pronation/supination) will be measured during several tasks during one 3-4 hour testing period.
- Wrist angle [ Time Frame: During task completion ]The wrist angle (flexion/extension and abduction/adduction) will be measured during several tasks during one 3-4 hour testing period.
- Torso angle [ Time Frame: During task completion ]The torso angle (rotation, forward/backward bending and right/left sideways bending) will be measured during several tasks during one 3-4 hour testing period.
- Validation of robotics based human body model [ Time Frame: After motion data analysis ]The robotics based human body model will be validated by comparing the joints (shoulder, elbow, wrist, torso) angles collected from the motion analysis system while participants are completing activities of daily living with the joint angles predicted by the model. The two data sets will be compared using a root mean error calculation.
