Clinical feasibility and interpretability of the Dynamic weight-bearing assessment of pain (DAP) in knee osteoarthritis

We developed the Dynamic weight-bearing Assessment of Pain (DAP), a performance measure with integrated pain evaluation. The DAP is based on input from both patients and health professionals, ensuring the content validity and clinical relevance of the performance in the test (weight-bearing knee bends). Acceptable reproducibility of the DAP has been established in a population of people with mild knee OA, but other psychometric properties remain to be tested, including feasibility and interpretability in a clinical setting. The objectives to this study are to evaluate the feasibility of the DAP for patients with knee OA in clinical physiotherapy practice, and to investigate the interpretability of the DAP for patients with knee OA in clinical physiotherapy practice by estimating a cut-off score for a minimum clinically important change.
