Abstract

OBJECTIVE: To develop a quantitative, inexpensive and easy to use tool, for assessing proprioception of the lower extremity of individuals post-stroke, and examine its test-retest reliability and known-groups validity. METHODS: The Lower Extremity Position Test was developed. Testing procedure: seated subjects were asked to reproduce 12 cm or 22 cm distances on a plastic surface, by verbally stopping passive movement of the foot produced by the tester. The deviation from the target point was measured as the mismatch score. Fifty one subjects post-stroke (n = 51) participated in prospective test-retest assessment. The tests were performed one week apart by a single assessor, in physical therapy out-patient clinics. The t-Test, ICC and Bland-Altman tests were used to determine known-groups validity by determining leg differences and test-retest reliability. RESULTS: Post-stroke involved foot demonstrated significantly higher mismatch scores then the uninvolved foot did (p < 0.0001). Good test-retest reliability was demonstrated for the involved leg for both 12 cm and 22 cm distances (ICC = 0.79 and 0.85, respectively). The 95% repeatability ranges were leg related. CONCLUSIONS: The Lower Extremity Position Test (LEPT) is a newly-developed testing tool with good clinical utility, reliable in post-stroke population and has known-group validity (involved versus uninvolved foot).
