The Disability Assessment Scale (DAS) evaluates upper-limb functional disability in patients with spasticity following stroke. The DAS was developed as a tool that objectively evaluates functional impairment resulting from spasticity.
- Hand hygiene
- Extent of palm maceration, ulceration or infection.
- Cleanliness of the palm, ease of cleaning, nail trimming.
- Effect of hygiene-related disability on other areas of functioning.
- Ability to dress.
- Effect of dressing-related disability on other areas of functioning.
- Limb position abnormality.
- Amount of abnormal limb position.
- Intensity of pain or discomfort related to upper-limb spasticity.
- Interference with activities of daily living.
Description of tasks:
Patients are interviewed to determine the extent of functional impairment for the following 4 areas:
- Hygiene: The rater assesses the extent of palm maceration, ulceration, or infection; cleanliness of the palm, ease of cleaning, and nail trimming; and the effect of hygiene-related disability on other areas of functioning.
- 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
- Pain: The rater assesses the intensity of pain or discomfort related to upper-limb spasticity and interference with activities of daily living.
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).
Not typically reported.
Can be used with:
Clients with stroke with spasticity.
Should not be used with:
Clients without spasticity.
