Purpose

The CMS measures overall function using subjective and objective measurements of the patient’s shoulder based on their pain, ROM, strength, ability to perform ADLs, and upper extremity function.

Key Descriptions

  • The test is divided into 4 subscales for a total of 100 points
    ○ Pain = 15 points
    ○ ADLs= 20 points
    ○ ROM (shoulder flexion, internal rotation, external rotation, and abduction) = 40 points
    ○ Strength = 25 points
  • Subjective findings account for 35 points and objective findings account for 65 points

Professional Association Recommendation

The European Society for Shoulder and Elbow Surgery (Vrotsou, et al., 2018)

Considerations

  • Not appropriate for patients with shoulder instability
  • A single pain scale is difficult to capture a patient’s actual pain
  • The function report is not specific to any activity
  • There is no standardized strength measurement method
