Background: Accurate measurements of knee and hip motion are required for management of musculoskeletal The purpose of this investigation was to compare three techniques for measuring motion at the hip and Methods: Using infrared motion capture analysis as the reference standard, hip flexion/abduction/internal rotation/ external rotation and knee flexion/extension were measured using visual estimation, goniometry, and photography Conclusions: There was no clinically significant difference in measurement accuracy between the three techniques Digital photography only showed higher precision for two joint motions (hip abduction Keywords: Hip, Knee, Range of motion, Digital photography, Goniometry, Visual estimation only significant differences identified were that hip abduction was more precisely measured with digital photography than visual estimation (93% vs. equivalent accuracy of digital photography and goniometry in measuring knee flexion and extension (Murphy	./cache/work_4oa7kezpvfalhjseax2eet65am.pdf	./txt/work_4oa7kezpvfalhjseax2eet65am.txt
