  • Pain score
  • Functional assessment
  • Range of motion
  • Strength measures.

Scoring System

The score consists of four variables that are used to assess the function of the shoulder. The right and left shoulders are assessed separately.

Two variables are subjective [patient tells about the intensity of the variable and two are objective [Examiner examines the variable and notes the finding.

The subjective Variables [Maximum Score -35]

  • Pain  – Absence of pain gets maximum score 15
  • Limitation of Activities of daily living (sleep, work, recreation / sport). No limitations gets maximum score, 20

The subjective variables add to a maximum score of 35.

The objective Variables [Maximum Score - 65]

  • Range of motion – Maximum score 40
  • Strength – Maximum Score 25

Objective variables add to a total of 65.

Total Constant Score is calculated by adding the scores from subjective and objective variables.

Maximum possible total score is 100.
