Performance Evaluation of a Gamified Physical Rehabilitation Balance Platform through System Usability and Intrinsic Motivation Metrics
Abstract
Article history: Received: 09 December, 2020 Accepted: 16 February, 2021 Online: 25 February, 2021 Motivation significantly influences the outcome in the rehabilitation of patients. Several developments have been made to assess and increase patient motivation by addressing factors linked to motivation such as the personality of the patient, professional administering rehabilitation, and the rehabilitation environment. The main objective of the study is to evaluate the reliability of a gamified environment for the rehabilitation of stroke patients by testing its functionalities within standard physical therapy time and intervals. To achieve this, calibration was characterized. Also, user feedback was taken in the form of questionnaires based on the System usability scale (SUS) and Intrinsic Motivation Inventory (IMI). Based on the SUS scale, results show that the game manipulability is good, the game concept and design is satisfactory, and the game comprehensibility is also good based on the qualitative conclusion per SUS score. For the IMI ratings, it was found out that the highest rating was the perceived choice which indicates their voluntary participation in the game. Some improvements can still be added to the game itself to increase the motivation of patients. The balance board manipulability and the recalibration time interval can be further improved for comfort and ease of use by the patients.
