Multicenter StudyReliability, validity, responsiveness, and minimal important change of the Disabilities of the Arm, Shoulder and Hand and Constant-Murley scores in patients with a humeral shaft fracture.
The Disabilities of the Arm, Shoulder and Hand (DASH) and Constant-Murley scores are commonly used instruments. The DASH is patient-reported, and the Constant-Murley combines a clinician-reported and a patient-reported part. For patients with a humeral shaft fracture, their validity, reliability, responsiveness, and minimal important change (MIC) have not been published. This study evaluated the measurement properties of these instruments in patients who sustained a humeral shaft fracture. ⋯ The DASH and Constant-Murley are valid instruments for evaluating outcome in patients with a humeral shaft fracture. Reliability was only shown for the DASH, making this the preferred instrument. The observed MIC and SDC values provide a basis for sample size calculations for future research.
