Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Restoration of Movement | The primary outcome of restoring movement will be evaluated through Graded Redefined Assessment of Strength, Sensibility & Prehension. The performance will be graded on a numeric scale from 0-92, where a higher number indicates a better outcome.
Participants will complete 10 distinct arm, wrist, and finger movements. The movements will be evaluated on a 5-point scale ranging from no movement to normal movement for a total of 0-50. Participants will be asked to perform a cylindrical grasp, key pinch, and a thumb-index pinch. The movements will be evaluated on a 4-point scale ranging from an inability to position wrist and fingers to able to perform movement with normal force for a total of 0-12. Participants will be asked to pour water, unscrew lids, place pegs on a board, open a lock, drop coins in a slot, and screw nuts. The movements will be evaluated on a 5-point scale ranging from 0% completed to 100% completed with expected grasp and no difficulties for a total of 0-30. |
The primary outcome will be assessed over the course of 12 months during the study's restoration sessions. | |
Primary | Restoration of Sensation | The primary outcome of restoring the perception of tactile sensation of the hand will be evaluated through the 5-Point Likert Scale. Participants will be asked whether they perceive sensation in response to objects being placed against the hand and fingertips. Participants will indicate whether they feel the object by selecting either strongly disagree (1), disagree (2), neutral (3), agree (4), or strongly agree (5). A higher total response score indicates an improvement in outcome. | The primary outcome will be assessed over the course of 12 months during the study's restoration sessions. |
