Also, to determine the minimal clinically importance difference (MCID), responsiveness, and<br>optimal cut-off point specific to adhesive capsulitis for conditions of high and low disability, using the Thai version<br>of QuickDASH.<br><strong>Methods</strong>: A cohort study was conducted in two hospitals over six weeks of physical therapy. Eighty-seven adhesive<br>capsulitis patients participated in this study. Clinical outcomes provided by participant self-assessment using Thai<br>QuickDASH and Global Rating of Change (GRoC) scales were compared with irritability outcomes provided by a<br>physical therapist. Thai QuickDASH is the validated outcomes measurement tool for adhesive capsulitis and GRoC<br>is recommended as a standard external anchor. This anchor-based method and receiver-operating characteristics<br>(ROC) were analysed to clarify MCID and responsiveness.<br><strong>Results</strong>: The highest correlation was between the Thai QuickDASH and pain during passive shoulder elevation<br>(rho = 0.638). MCID scores ranged from 9.1 to 20.4. The optimal cut-off point between high and low disability was<br>31.8, attained by a combination of two references; one was a score of at least GRoC+1 and the other was irritability<br>outcome defined by pain during passive shoulder elevation.<br><strong>Conclusion</strong>: Responsiveness and MCID measured by the Thai QuickDASH is specific to adhesive capsulitis.<br>A combination of GRoC as a standard external anchor and irritability outcome gave a precise cut-off point for<br>improvement. Overall management of adhesive capsulitis, including continuing evaluation, treatment justification,<br>and decision planning, should be based on qualified confirmation of MCID and responsiveness.</p> ER -
