Minimal important changes in the Constant-Murley score in patients with subacromial pain.
OBJECTIVE The purpose of this study was to determine the minimal important change ( MIC ) of improvement in the Constant-Murley score in patients with long-st and ing subacromial pain and in subgroups of patients with subacromial pain with and without rotator cuff ruptures . METHOD The MIC was estimated by the anchor-based MIC distribution method , which integrates an anchor- and distribution-based approach : the optimal cutoff point of the receiver operating characteristic curve ( MICROC ) and the 95 % limit cutoff point ( MIC95 % limit ) . The study population consisted of 93 patients included in a r and omized clinical trial evaluating the effect of a specific exercise strategy .  RESULTS The MICROC was found at a mean change of 17 points in the Constant-Murley score , which corresponds to a sensitivity of 91 % and a specificity of 79 % . The MIC95 % limit was found at a mean change of 24 points . In the subgroup analysis , the MICROC was found at a mean change of 19 points and the MIC95 % limit at 18 points in patients with an intact rotator cuff . In patients with rotator cuff ruptures , the MICROC was found at a mean change of 15 points and the MIC95 % limit at 30 points . CONCLUSION The Constant-Murley score is able to detect the MIC in individual patients with long-st and ing subacromial pain when the rotator cuff is intact . The estimated MIC values could be used as an indication for relevant changes in the Constant-Murley score in clinical practice and guide the clinician in how to interpret the results of specific treatments
