Description of tasks
Patients are interviewed to determine the extent of functional impairment for the following 4 areas:

  • Dressing: The rater assess the patient’s ability to dress and the effect of dressing-related disability on other areas of functioning
  • Limb position: The rater assesses the amount of abnormal position of the limb; and

Scoring and Score Interpretation
The DAS Scale uses a 4-point rating scale according to the following criteria:

  • 0 – no disability
  • 1 – mild disability (noticeable but does not interfere significantly with normal activities
  • 2 – moderate disability (normal activities require increased effort and/or assistance)
  • 3 – severe disability (normal activities limited)
