reha buddy digitalizes the documentation of rehabilitation in clinics and rehabilitation centers to facilitate the work of therapists and provide objective data of the treatment success. The solution consists of a mobility monitor with the reha buddy+ app installed. This app can use the built-in sensors of the mobility monitor to collect information about patients in various standardized assessments such as the 6-minute walk test. In addition, other helpful functions for therapists are included, making the system a comprehensive therapy assistant. Clinics and rehabilitation centers can thus reduce administrative work, and increase the quality of rehabilitation.
