Dimensionality and scalability of the Motor Assessment Scale (MAS)

Abstract

We conclude that the scalability of the different items is not optimal. For some items, the top and/or bottom levels are overrepresented and for other items the middle levels tend to cluster. There seems to be a single construct except for one of the items. The instrument also showed the same meaning for the different subgroups.

Assessment of the upper limb in acute stroke: The validity of hierarchal scoring for the Motor Assessment Scale

“…As reported by many researchers, the MAS has significant floor and ceiling effects (Lannin, 2004; Hsueh & Hsieh, 2002; Williams, Galea & Winter, 2001). As a result of previous research the general tonus item, designed to measure muscle tone, has been removed from the MAS due to low reliability (Aamodt, Kjendahl & Jahnsen, 2006; Loewen & Anderson, 1988).…”

Confiabilidade, compreensão e aceitação da versão em português da Motor Assessment Scale em pacientes com acidente vascular encefálico

“…It is one of the scales recommended for post-stroke patients 18 and it has great potential in clinical assessment and in post-stroke rehabilitation research 13,14,26,27 . In the present study, both intra-and interrater reliability of the Portuguese version of the MAS were evaluated, with the participation of 23 physical therapists and 15 post-stroke patients.…”

“…The MAS has been extensively used in research and clinical practice worldwide 12,15,26 , and it includes both qualitative and quantitative aspects of functional tasks 12,[14][15][16]26 . It is one of the scales recommended for post-stroke patients 18 and it has great potential in clinical assessment and in post-stroke rehabilitation research 13,14,26,27 .…”

“…Although item 8 had high reliability, it was the most mentioned in this aspect. It is likely that the scores were not organized in accordance with the increased difficulty in this item 14,26,27,29 . A possible explanation for its high reliability would be that many patients are unable to carry out all the components of the upper extremity (UE) assessment, resulting in a reduction in error probability 6 .…”

Older adults experience difficulty completing the lines and dots tasks of the Motor Assessment Scale

“…[13,15] Subsequent Rasch analysis confirmed that for item eight, the motor behaviours are not ordered hierarchically. [9][10][11]16] Consistently, the two most difficult behaviours for stroke survivors to achieve on the advanced hand activities item are motor behaviours three and four. These two motor behaviours involve drawing 10 horizontal lines and making 10 dots in a set timeframe respectively and will hereafter be referred to as the 'lines task' and 'dots task'.…”
