Use of Dynamic Arm Supports to Promote Activities of Daily Living in Individuals With DMD

This study is a longitudinal, randomized control trial evaluating the use of two commercially
available dynamic arm support devices (Armon Ayura-Kinova and JAECO WREX) to promote
participation in activities of daily living in non-ambulatory individuals with Duchenne
muscular dystrophy (DMD) with upper extremity weakness. Up to 30 individuals will be enrolled
to participate in this research study, which includes a two-week baseline data collection
period, a four-week device trial and a two-week post device data collection period.
Participants will be randomly assigned to trial one of the dynamic arm support devices during
the four week in-home trial. The ActiGraph, a wrist worn activity monitoring device, will be
worn during the baseline period, the device trial and the post device data collection period
to capture UE movement patterns. UE performance will be further quantified with use of a
physical motor assessment, the Performance of Upper Limb (PUL) assessment and patient
reported outcomes. Data gleaned will provide important knowledge and objective results
regarding the potential benefit of dynamic arm supports in individuals with DMD with limited
functional use of their upper extremities.

Inclusion Criteria:

1. 14 years of age or older

2. Self-report diagnosis of Duchenne muscular dystrophy (DMD)

3. Use a wheelchair for mobility

4. Score 3-5 on the Brooke UE Scale

5. Self-report of needs assistance/unable to achieve independently on at least 10 items
on the UL ADL self-report questionnaire

6. Able to follow instructions

7. Informed consent provided by self (18 and over) or by parent or legal guardian (if
under the age of 18)

Exclusion Criteria:

1. Does not have minimum level of UE function to operate the assigned dynamic arm support
(Score of 6 on the Brooke UE scale or any other impairment limiting use)

2. The assigned dynamic arm support is unable to be mounted to wheelchair (mounts will
vary based on manufacturer/model of wheelchair)
