Low-cost virtual rehabilitation games: House of quality to meet patient expectations

Patients' willingness to play is essential for rehabilitation games. This study (1) identified patients' general expectations for rehabilitation games; and (2) evaluated two newly developed low-cost rehabilitation games through surveys. Patients were found to expect low-cost systems (<; $100), ease of use, interesting game contents, proven clinical efficiency, and access to rehabilitation games without prescription although welcoming therapists to follow their progress. House of quality analysis performed for the two developed rehabilitation games based on the patient expectations identified the need to improve reliability and precision of the low-cost hardware as well as to demonstrate clinical benefits.
