Abstract

Purpose: The purpose of the present study was to investigate the effects of the contact-relax (CR) intervention on pelvic alignment in subjects with habitual poor posture. Methods: Fifteen subjects who have habitual poor posture participated in this study. The subjects received an intervention inducing pelvic posterior depression with the elevated pelvic side. Pre- and post-intervention, and two weeks after intervention, the pelvic alignment was measured with a palpation meter (PALM) and a three-dimensional diagnostic imaging system. Results: Measuring with PALM, the pelvic height and anterior tilt angle were significantly decreased immediately after and were still decreased two weeks after intervention, compared to the pre-measurement (p<0.05). Three-dimensional pelvic alignment was also significantly different between measurement points, while the pelvic position (pelvic lateral tilt) was significantly decreased after intervention (p<0.05). Conclusion: By applying the intervention generating CR on an elevated pelvis, frontal pelvic alignment can be improved.
