Motor Assessment Scale (MAS) Evaluation Summary
|What does the tool measure?||Everyday motor functioning|
|What types of clients can the tool be used for?||Patients with stroke|
|Is this a screening or assessment tool?||Assessment|
|Time to administer||Studies have reported administration times ranging from 15 to 60 minutes.|
|Versions||Upper Limb/Extremity Motor Assessment Scale (UL-MAS or UE-MAS); Modified Motor Assessment Scale (MMAS)|
|Other Languages||English and Norwegian|
|Reliability||– No studies have examined the internal consistency of the MAS.
– Only 1 study has examined the test-rest reliability of the MAS, reporting excellent test-retest.
– No studies have examined the intra-rater reliability of the MAS.
– Out of 2 studies that examined the inter-rater reliability of the MAS, both reported excellent inter-rater (with the exception of the general tonus item, which demonstrated poor inter-rater reliability).
|Does the tool detect change in patients?||
One study found minimal floor and ceiling effects for the UL-MAS in acute/subacute post-stroke patients. In another study, large floor and ceiling effects for Upper Arm Function and Hand Movements items and substantial floor effects for Advanced Hand Activities were found; however, the study has been criticized for inclusion of participants that were as long as 6 years post-stroke.
|Acceptability||The MAS is a fairly simple and short measure to administer. A proxy respondent is not appropriate for this performance-based measure. For severely affected patients or patients with aphasia, we recommend administering the Fugl-Meyer Assessment of Sensorimotor Recovery After Stroke (FMA) rather than the MAS.|
|Feasibility||A short instruction and practice period is recommended prior to administering the test in a formal setting. A number of items are required as equipment for the MAS, however all items are readily available.|
|How to obtain the tool?||The MAS is available for free and can be found in Carr et al. (1985). Click here to view a copy of the MAS.|
