Abstract EN
Objectives.
(1) To develop two independent measurement scales for use as items assessing hand movements and hand activities within the Motor Assessment Scale (MAS), an existing instrument used for clinical assessment of motor performance in stroke survivors; (2) To examine the psychometric properties of these new measurement scales.
Design.
Scale development, followed by a multicenter observational study.
Setting.
Inpatient and outpatient occupational therapy programs in eight hospital and rehabilitation facilities in the United States and Canada.
Participants.
Patients (N=332) receiving stroke rehabilitation following left (52%) or right (48%) cerebrovascular accident; mean age 64.2 years (sd 15); median 1 month since stroke onset.
Intervention.
Not applicable.
Main Outcome Measures.
Data were tested for unidimensionality and reliability, and behavioral criteria were ordered according to difficulty level with Rasch analysis.
Results.
The new scales assessing hand movements and hand activities met Rasch expectations of unidimensionality and reliability.
Conclusion.
Following a multistep process of test development, analysis, and refinement, we have redesigned the two scales that comprise the hand function items on the MAS.
The hand movement scale contains an empirically validated 10-behavior hierarchy and the hand activities item contains an empirically validated 8-behavior hierarchy.
