OBJECTIVE: To develop a computerized adaptive testing system of the Fugl-Meyer
motor scale (CAT-FM) to efficiently and reliably assess motor function in
patients with stroke. DESIGN: First, a simulation study was used to develop and
examine the psychometric properties of the CAT-FM. Second, a field study was
employed to determine the administration efficiency of the CAT-FM. SETTING: One
medical center and 1 teaching hospital. PARTICIPANTS: Patients' responses (n=301)
were used for the simulation study; 49 patients participated in the field study.
INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The 2 CAT-FM item banks
(upper extremity and lower extremity) include 37 items from the original
Fugl-Meyer scale. The reliability, validity, and responsiveness of the CAT-FM
were determined by the simulation study. RESULTS:
Two stopping rules (reliability
>/=0.9 or an increase of reliability <.01 after testing an item) were used. The
simulation study showed that the CAT-FM had high reliability (>/=.93 for
upper-extremity and lower-extremity subscales) and concurrent validity (Pearson
r>/=.91 for the upper-extremity and lower-extremity subscales and motor scale).
The responsiveness was moderate (standardized response mean for the upper
extremity=.67, lower extremity=.79, and motor=.77) for the 226 patients who
completed both assessments at 14 and 90 days after stroke.
The field study found
that, on average, the time needed to administer the CAT-FM was 242 seconds with
4.7 items. CONCLUSIONS: The CAT-FM is an efficient, reliable, valid, and
responsive clinical tool for assessing motor function in patients with stroke.
