Overview
SECONDARY
This study aimed to investigate the usability of the newly developed exergame-based COCARE system for telerehabilitation in OAs. Usability was assessed quantitatively and qualitatively, and valuable insights into the perspectives of OAs and HPs regarding the COCARE system was gained. Overall usability, enjoyment, acceptance, and safety ratings were acceptable. The analysis revealed that some parts of the system need improvement—especially regarding comprehensibility of assessments and game instructions and hardware features. Almost all secondary outcomes showed manifold correlations with the usability outcomes. Each of these outcomes will be discussed in the following sections.
