Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The two primary endpoints are the comparison of baseline-adjusted follow-up scores between intervention group and control group regarding osteoarthritis-specific pain (Knee Osteoarthritis Outcome Score, Subscale Pain) and physical function (Knee Osteoarthritis Outcome Score, Subscale Activities of daily living) directly after the 12-week intervention phase. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary endpoints include self-reporting on further health outcomes (e.g., health-related quality of life (VR12), fear of movement, other knee-related complaints (Knee Osteoarthritis Outcome Score, other subscales), Patient's Global Assessment). Objective measures consider leg strength and strength endurance testing (30-Second Chair Test). During the intervention, the perceived exertion during exercising, the exercise adherence as well as safety aspects during the intervention (pain, unexpected events or side effects) will be recorded. In addition, usability and patient satisfaction will be evaluated. | — |
