Trial Outcomes & Findings for Use of Dynamic Arm Supports to Promote Activities of Daily Living in Individuals With DMD (NCT NCT03531788)

NCT ID: NCT03531788

Last Updated: 2022-02-18

Results Overview

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.

Baseline Characteristics

Data were collected using wrist worn Actigraph GT9x during baseline assessment of upper extremity function without the dynamic arm support device. Data were collected over a 2-week time period and means and standard deviation activity counts were used. Actigraph GT9x provides activity counts which measure movement in all directions. The Actigraph was not worn during baseline testing for some participants, resulting in missing activity count data. Higher activity counts represents more movement.

PRIMARY outcome

Timeframe: Collection of activity counts through the ActiGraph GT9x occurred during testing phase with and without the upper extremity arm device.

Population: All participants who had completed the testing period while wearing the Actigraph GT9x are reported. All participants were tested, but data are missing due to technology failure or not wearing the ActiGraph during testing. Participants who were not wearing the ActiGraph during testing are not reported. Comparisons between groups (Kinova and WREX) were not analyzed due to small sample sizes in both groups.

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.

PRIMARY outcome

Timeframe: Collection of activity counts through the ActiGraph GT9x occurs from baseline through the end of the 4-week device trial.

Population: All participants who completed the testing period while wearing the Actigraph are reported. Comparisons between groups (Kinova and WREX) were not analyzed due to small sample sizes in both groups.

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.

SECONDARY outcome

Timeframe: The GAS is completed and scored at baseline and at the end of the 4 week trial with and without the device.

Population: Participants were included in this analysis if they completed the Goal Attainment Scale (GAS) with and without the use of the arm device (Kinova or WREX). Sample sizes were too small to use statistical analyses for comparisons between groups.

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).
