Hip proprioception has been tested on various populations, but there is limited research on healthy young adults. Primary assessments of proprioception for hip have been on joint position sense (JPS), but fewer studies have accomplished this in an unconstraint testing apparatus with angular repositioning tasks. Purpose of this study was to examine effects of active and passive repositioning on hip JPS in healthy young adults. It was hypothesized that active JPS error scores would be lower compared to passive JPS error scores. There was a total of 15 subjects in the study. Digitization of anatomical landmarks were used to create a virtual coordinate system to estimate hip joint center. JPS protocol consisted of three different conditions, passive with hip trolley, active with hip trolley and active without hip trolley. All conditions tested three different target positions of 30°, 45° and 60° degrees of hip flexion. The results of absolute and constant JPS error scores revealed that there was a linear decrease in average absolute error score, which elicited a decrease in levels of muscular control during flexion and accuracy of reposition targets (p=.001). The reduction of error score in passive JPS tasks may have allowed for subjects to concentrate on target angles more, because of less demand for joint stabilization. Unfortunately, most research contradicts the study’s findings. Future research should focus on possible variables that further contribute to hip proprioception. Particularly studying the effects of lower back stiffening and fascial interactions with hip muscle activation.
