The Motor Assessment Scale (MAS) is a performance-based scale that was developed as a means of assessing everyday motor function in patients with stroke (Carr, Shepherd, Nordholm, & Lynne, 1985).
Features of the measure
The MAS is comprised of 8 items corresponding to 8 areas of motor function.
- Supine to side lying
- Supine to sitting over the edge of a bed
- Balanced sitting
- Sitting to standing
- Upper-arm function
- Hand movements
- Advanced hand activities.
Patients perform each task 3 times and the best performance is recorded.
Also included is a single item, general tonus, intended to provide an estimate of muscle tone on the affected side (Carr et al., 1985).
Although a number of items are required to administer the MAS, the equipment is easy to acquire. The following equipment is needed:
- Eight Jellybeans
- Polystyrene cup
- Rubber ball
- Two Teacups
- Prepared sheet for drawing lines
- Cylindrical object like a jar
- All items are assessed using a 7-point scale from 0 – 6. A score of 6 indicates optimal motor behavior. Item scores can be summed to provide an overall score out of a possible 48 points.
- For MAS 1 to 5, completing a higher-level item suggests successful performance on lower-level items and thus lower-items can be skipped.
- The upper limb section (MAS 6-8) should be scored non-hierarchical, meaning that every item within the subsets should be scored regardless of its position within the hierarchy.
- Administration times ranging from 15 to 60 minutes.
