This study determined the test-retest reliability of Patrick's test as a hip range of motion assessment method. Fifty healthy college-aged men (mean age = 20.0 years) were studied during 2 testing sessions separated by 24 hours. A single inexperienced tester performed all the measurements in this study. Before data collection, the tester participated in a 15-minute instructional session on how to perform Patrick's test. To determine the range of motion associated with Patrick's test, the tester passively flexed, abducted, and externally rotated the hip of the lower extremity that was to be tested while subjects were in a supine position, so that the lateral malleolus of the tested lower extremity rested just superior to their opposite extended knee. The vertical distance between a mark on the lateral border of the patella of the tested lower extremity and the treatment table was then measured. The results revealed that Patrick's test demonstrated high test-retest reliability (intraclass correlation coefficient = 0.93). The results of this study support the use of Patrick's test as being a reliable measure of general hip motion when used by an inexperienced tester who participated in a 15-minute instructional session on how to perform Patrick's test.
