The Practical Work of Ensuring the Effective Use of Serious Games in a Rehabilitation Clinic: Qualitative Study

BACKGROUND: Many rehabilitation clinics adopted serious games to support their physiotherapy sessions. Serious games can monitor and provide feedback on exercises and are expected to improve therapy and help professionals deal with more patients. However, there is little understanding of the impacts of serious games on the actual work of physiotherapists. OBJECTIVE: This study aimed to understand the impact of an electromyography-based serious game on the practical work of physiotherapists. METHODS: This study used observation sessions in an outpatient rehabilitation clinic that recently started using a serious game based on electromyography sensors. In total, 44 observation sessions were performed, involving 3 physiotherapists and 22 patients. Observation sessions were documented by audio recordings or fieldnotes and were analyzed for themes using thematic analysis. RESULTS: The findings of this study showed that physiotherapists played an important role in enabling the serious game to work. Physiotherapists briefed patients, calibrated the system, prescribed exercises, and supported patients while they played the serious game, all of which amounted to relevant labor. CONCLUSIONS: The results of this work challenge the idea that serious games reduce the work of physiotherapists and call for an overall analysis of the different impacts a serious game can have. Adopting a serious game that creates more work can be entirely acceptable, provided the clinical outcomes or other advantages enabled by the serious game are strong; however, those impacts will have to be assessed on a case-by-case basis. Moreover, this work motivates the technology development community to better investigate physiotherapists and their context, offering implications for technology design.
