Objectives To investigate the relationship of forward head posture to heart rate variability and standing posture (pelvic tilt, knee flexion, calcaneal eversion). Methods In the present study, thirty two subjects were recruited by convenience sampling. The forward head posture was measured via the craniovertebral (CV) angle. The pelvic tilt angle, the knee flexion angle, the calcaneal eversion angle, and the heart rate variability were measured. The correlations of forward head posture to heart rate variability and standing posture (pelvic tilt, knee flexion, calcaneal eversion) were analyzed. Results In the present results, there was a significant negative correlation between X-ray CV angle and other regions except the headache. There was a weak positive correlation between Posture CV angle and SDNN. Significant positive correlation was found between KFA and difference between Lt. & Rt. CEA. Significant weak negative correlation was found between SDNN and difference between Lt. & Rt. CEA. Conclusions Biomechanical associated with physical pain and heart rate variability, and it is related to the forward head posture changes and also suggest that clinical care is needed for this.
