Objective: To determine the test-retest reliability and construct validity of a new lower-extremity motor coordination test, the Lower Extremity MOtor COordination Test (LEMOCOT). Design: To test reliability, subjects with impairments in at least 1 lower extremity were evaluated twice by the same evaluator. To test construct validity, the LEMOCOT scores obtained from subjects who had had a stroke were correlated with physical, functional, cognitive, and perceptual tests. Setting: Geriatric day hospital and functional intensive rehabilitation unit. Participants: In the reliability test, 29 people (mean age, 69.6y; range, 28-87y); in the construct validity, 144 people who recently had had a stroke. Intervention: Not applicable. Main Outcome Measures: In addition to the LEMOCOT, the following measures were used for construct validity: the Fugl-Meyer Assessment (motor function), Berg Balance Scale, 5-m walking test, 2-minute walking test, Functional Autonomy Measurement System, Modified Mini-Mental State Examination, and Motor-Free Visual Perceptual Test. Results: Intraclass correlation coefficients (ICCs) indicated that test-retest reliability is good (right-side ICC=.88; left-side ICC=.83). The construct validity of the LEMOCOT was demonstrated by obtaining high correlations with physical and functional tests (r range, .62-.79; P<.001) and no correlations with cognitive (r=.11, P=.20) or visual perceptual tests (r=.15, P=.08) and by discriminating between subjects discharged to long-term care versus other living environments (P<.001). Conclusions: The LEMOCOT is a simple lower-extremity motor coordination test that showed good test-retest reliability and construct validity. It can be used in clinical and research settings, specifically with people who have had a stroke. Other studies should be carried out to confirm its psychometric properties. © 2005 by American Congress of Rehabilitation Medicine and the American Academy of Physical Medicine and Rehabilitation.
