Constant Murley Score (CMS) Flow

Constant Murley Score flow

Introduction

The Constant–Murley Score (CMS) was introduced as an instrument to evaluate overall shoulder function, irrespective of diagnosis [1]. After the approval and recommendation of the European Society for Surgery of the Shoulder and the Elbow, the CMS became a widely used tool. In 2008, modifications to the score have been suggested by Constant et al. [2]

The CMS asses two subjective aspects answered by the patient: pain and activities of daily living (ADL) and two objective aspects answered by the orthopedic surgeon or the physiotherapist: range of motion (ROM) and strength. The subjective components can receive up to 35 points and the objective 65, resulting in a possible maximum total score of 100 points (best function) [1,3].

The Constant Murley Score flow contains the Constant Murley Score (CMS) questionnaire and associated calculation. After form submission, the Constant Murley Score calculation is executed automatically. It's easy to extend this flow with conditional logic based on the interpretation of the Constant Murley Score calculation.

Constant Murley Score (CMS) questionnaire

Questionnaire

The Constant-Murley score contains both physician-completed and patient-reported portions.

There are four scales:

  1. Pain (15 possible points)
  2. Activities of daily living (20 possible points)
  3. Mobility (40 possible points)
  4. Strength (25 possible points)

Interpretation

The total CMS scores ranges from 0 points (most disability) to 100 points (least disability).
