Study protocol and setup. Participants were recruited through the clinical partner. The orthosis was customized by fitting the scapular interface to each participant, see also Fig. 2. The range of motion task consisted of one study block without assistance, six study blocks with orthosis assistance set to different force levels, and one study block with therapist assistance. During each study block, participants performed two maximal arm elevations in both the flexion and abduction direction. The functional task consisted of one block without assistance and one block with orthosis assistance set to the force level rated most helpful by the participant. During each study block, participants performed two maximal arm elevations in flexion direction while holding a weighted bottle. Additionally, participants completed a qualitative questionnaire at the end of the study. Participants’ movements were recorded with a six-camera motion capture system and a ten-marker set
