An accurate, simple, and relatively inexpensive method for measuring hip-joint motion during walking with an electrogoniometer has been described. Average motion at the hip joint during walking for thirty-three normal subjects was 52 degrees in the sagittal plane, 12 degrees in the coronal plane, and 13 degrees in the transverse plane. Test-retest measurements for this method resulted in high coefficients of correlation. A typical normal pattern of motion was presented. We believe this method of measurement is practical and valuable for use in the study of hip disease.
