Abstract

This study reports the usability and performance evaluation of a mobile, detachable counterbalance arm sling (CBAS) designed to support upper-limb rehabilitation for people with hemiparesis. The device targets key clinical goals of shoulder stabilization, range-of-motion (ROM) support, and reduced therapist burden while remaining low-cost and locally manufacturable. A structured evaluation at a rehabilitation center engaged physiotherapists and a stroke survivor, using a three-part instrument including product rating, performance scale, and recommendation or comments. Respondents rated the CBAS from good to very good across eight usability criteria contains the ease of use, comfort, style, lightweight, functionality, ROM improvement, safety, ergonomics. 25% of the respondents rated performance superior and the remainder acceptable, with 100% recommending continued use. Findings align with contemporary evidence that weight-supporting/mobile arm support can foster arm activity and functional training in hemiparesis, and that usability-first design is crucial for adoption and adherence in real-world rehab. The CBAS demonstrates clinical promise and a path to scalable local production.
