Objectives: To evaluate the construct validity, inter- and intra-rater reliabilities, best scoring method and testing methods (direct vs video observations), and to determine the smallest real difference (SRD) and standard error of the measurement (SEM) of the lower Extremity Motor Coordination Test (LEMOCOT).
Design: Methodological study.
Subjects: Thirty-six stroke subjects.
Methods: Outcomes include measures of motor recovery, muscular tone, strength, motor coordination, foot tactile sensation, and gait speed.
Results: The LEMOCOT scores were able to discriminate between stroke individuals from those predicted for healthy subjects, between the paretic and non-paretic limbs for both the sub-acute and chronic groups and differentiated between individuals with different functional levels and degrees of motor recovery. For the intra- and inter-rater reliabilities, very high and significant coefficients were found for both the paretic and non-paretic lower limbs for both groups (intra-class correlation coefficients (ICC) > 0.97, p < 0.0001). Significant differences were found regarding all scoring methods (18.91 < F < 27.49, p < 0.0001), but they were not clinically important and all showed adequate test-retest reliability and acceptable SRD and SEM (< 15%) values. There was also agreement between the scores from the direct and video observations.
Conclusion: The LEMOCOT demonstrated adequate measurement properties in stroke subjects and, therefore, could be an appropriate measure for research and clinical purposes.
