We have developed a novel terminal device for a prosthetic arm that eliminates the functional tradeoffs seen in body-powered voluntary open devices. The primary goal of this study is to validate the performance of the device against the commercial state-of-the-art in upper limb terminal devices.

The Novel Prosthetic Hook is the investigational device that is being studied for its performance as an upper limb terminal device.
The Control Hook is a standard, commercially available prosthetic hook used as a comparison. In this intervention, it is configured with a light return spring.

Modified SHAP Average Completion Time
This is the average task completion time across all tasks performed in a modified version of the Southampton Hand Assessment Protocol (SHAP). The SHAP has been modified in this study to include only the relevant assessments to the prosthetic hooks being tested. A lower average score indicates better performance.
Time frame: through study completion, an average of 1 day
Clothespin Relocation Task Average Time
This is a functional hand assessment that measures the time it takes to reposition clothespins of differing stiffnesses. Lower completion times indicate better performance.
Time frame: through study completion, an average of 1 day
Borg Rating of Perceived Exertion (RPE)
This is a scale of 0 to 10 with 0 indicated by the participate as a measure of how difficult a task is.
Time frame: through study completion, an average of 1 day
NASA Task Load Index
The NASA Task Load Index method assesses work load. The aggregate score reported scales from 0 to 100, where 100 indicates the maximum (hardest) workload.
Time frame: through study completion, an average of 1 day
