Objective
[edit | edit source]
The Motor Assessment Scale (MAS) is used to assess everyday motor function in patients with stroke.
Intended Population
[edit | edit source]
Used widely in assessing functional ability for patients with stroke
Method of Use[edit | edit source]
Description:
- 8 items assess 8 areas of motor function
- Patients perform each task 3 times, only the best performance is recorded
- Items (with the exception of the general tonus item*) are assessed using a 7-point scale (0 to 6)
- A score of 6 indicates optimal motor behavior
- Item scores (with the exception of the general tonus item) are summed to provide an overall score (out of 48 points)
- Completing a higher-level item suggests successful performance on lower-level items and thus lower-items can be skipped.
- For the general tonus item, the score is based on continuous observations throughout the assessment. A score of 4 on this item indicates a consistently normal response, a score > 4 indicates persistent hypertonus, and a score < 4 indicates various degrees of hypotonus (Carr et al, 1985[1]).
Equipment Required:
Stopwatch
8 Jellybeans
Polystyrene cup
Rubber ball
Stool
Comb
Spoon
Pen
2 Tea cups
Water
Prepared sheet for drawing lines
Cylindrical shaped object like a jar

Evidence[edit | edit source]
Reliability[edit | edit source]
Test-retest Reliability:
Chronic Stroke:
(Carr et al, 1985; n = 15; mean age = 70 years, range = 42 to 85) [2]
- Excellent test-retest reliability: r ranged from 0.87 to 1.00 (mean r = 0.98)
Interrater/Intrarater Reliability:
Chronic & Acute Stroke:
(Carr et al, 1985; 20 clinical raters; n = 5; mean age = 65 years, range = 55 to 78; mean time since stroke onset = 14 (range = 6 to 40) weeks) [3]
- Excellent Interrater Reliability; 87% overall agreement between raters (mean correlation r = 0.95; most agreement = balanced sitting (r = 0.99); least agreement = sitting to standing (r = 0.89).
Validity[edit | edit source]
Criterion Validity:
Acute Stroke:
(Malouin et al, 1994, n = 32, mean age = 60 years, mean time since stroke = 64.5 days) [4]
- Excellent Concurrent Validity with Fugl-Meyer (FMA) total scores (r = 0.96, not including general tonus items)
- Adequate to Excellent item level Concurrent Validity between MAS items and similar FMA items (r = 0.65 to 0.93)
- Poor Concurrent Validity with MAS and FMA sitting balance (r = -0.10)
Construct Validity:
Acute Stroke:
(Tyson & DeSouza, 2004; n = 48; mean age = 66.7 (12.5) years; median time since stroke = 11 weeks) [5]
MAS and functional balance test:
- Adequate Convergent Validity: Sitting arm raise (no. of raises; r = 0.33*)
- Adequate Convergent Validity: Sitting forward reach (cm, r = 0.54**)
- p < 0.05
** p < 0.01
Content Validity:
The MAS was developed by Carr and Shepherd (1985) based on many years of experience with similar measures
Responsiveness[edit | edit source]
Chronic & Acute Stroke:
(English et al, 2006) [6]
MAS sensitivity:
Item | Dimension | Effect | Effect Size (d) | % Change |
1 | Rolling | Large | 1.03 | 31.1 |
2 | Lie to sit | Moderate | 0.74 | 44.3 |
3 | Balanced Sitting | Moderate | 0.61 | 60.7 |
4 | Sit to Stand | Large | 0.85 | 18 |
5 | Walking | Large | 1.02 | 19.7 |
6 | Upper arm function | Small | 0.36 | 44.3 |
7 | Hand movements | Small | 0.43 | 55.7 |
8 | Advanced hand activities | Moderate | 0.50 | 63.9 |
