Objective: To present a practical and useful approach to the most used scales in the musculoskeletal area with its own "Minimal Clinically Important Difference" (MCID) for those interested in using and interpreting the findings of clinical studies. Methods: A Narrative review, in which, by consensus with rheumatology and orthopedic specialists, a selection was made of the scales that evaluate function or pain in shoulder, elbow, hip and knee, and had a methodological score ≥ 5/6. , A PubMed search was also conducted to find the number of citations of each of the measurement scales evaluated. Results: A total of 23 scales of function and pain were analyzed: shoulder 6, elbow 4, hip 3, 4 knee, 4 hip/knee, and 2 general, in which the respective minimum clinically important difference was reported. Conclusions: The minimum clinically important differences is a useful tool for clinicians in the area of skeletal use and interpretation of measurement scales, and the effects of intervention measures in clinical studies on muscle diseases.
