Passive mechanical arm support (elastic bands to balance arm) |
- Change in Upper Extremity Activity Counts (Movement) Through Actigraphy [ Time Frame: Collection of activity counts through the ActiGraph GT9x occurred during testing phase with and without the upper extremity arm device. ]Measured through the ActiGraph GT9X wrist worn activity monitoring device: The multi-axis activity monitor measures activity counts that represent movement of the upper extremity. We calculated the average activity counts during testing items with the arm device and testing items without the arm device. We then calculated change scores (average activity counts without the device minus average activity counts with the device). Higher activity counts indicate more effort and more movement during item testing without the device compared to using the device.
- Change in Upper Extremity Position Through Actigraphy [ Time Frame: Collection of activity counts through the ActiGraph GT9x occurs from baseline through the end of the 4-week device trial. ]Measured through the ActiGraph GT9X wrist worn activity monitoring device: The multi-axis activity monitor (gyroscope within the monitor) measures activity counts (movement) per second in the x, y, and z planes. Change in average activity counts (movement) in x, y, and z planes during the 4-week trial period compared to the 2-week baseline period are reported (higher activity counts means more movement during trial). X plane is horizontal movement, y plane is vertical movement, and z plane extends outward from the body.
- Goal Attainment Scale (GAS) [ Time Frame: The GAS is completed and scored at baseline and at the end of the 4 week trial with and without the device. ]The GAS is a personal interview which allows the individual to determine important and personally meaningful goals. Each participant chose three individualized goals to work on and assess at the end of the study. Goal scaling is standardized in order to calculate the extent to which a patient's goals are met.The GAS uses a 5-point rating scale to determine if the goal was not met (-2) up to a greater than expected meeting of the personal goal (+2). A score of 0 indicates the goal was met as anticipated. We report the average change in the score of each goal when the participant uses the trial device. Here we use change scores which range from 0 (performed the same with and without the device) to 4 (participant performed at a greater than expected level with the device).
