Table 2: Function test scores with and without dynamic arm support at baseline (T2). The immediate effectiveness of the DAS is described separately for each participant (ID 1-8). Efficacy parameters are the ARAT, MFM D3, 9HPT and the Jebsen test. Differences are individual results of the non-dominant (trained) arm with DAS minus those of the same arm without DAS at baseline (T2). For the ARAT and MFM D3, a positive difference indicates an improved motor function by using the DAS. A negative difference on the 9HPT and Jebsen tests indicates a decreased time necessary to perform the task by using the DAS. DAS: Dynamic arm support; ARAT: Action Research Arm Test; MFM: Motor Function Measure; 9HPT: Nine-Hole Peg Test; Jebsen: Jebsen Taylor Hand Function Test; J1: Turning cards; J2: Small objects; J3: Feeding; J4: Stacking; J5: Light objects; J6: Heavy objects; ND: Not determined; U: Unable to perform; NA: Not applicable.
