Impact of forward head posture correction on craniovertebral angle,neck disability,and spinal electromyography: A randomized controlled trial

Abstract

Background

Forward head posture (FHP) is a common malalignment affecting the cervicothoracic spine. This deviation is associated with neck disability and muscle imbalance.

Objective

This study aimed to investigate the efficacy of FHP correction using regional versus comprehensive spinal programs on the craniovertebral (CV) angle, neck disability, and spinal muscle activity.

Methods

Sixty participants with FHP were randomly assigned to receive either a cervicothoracic correction program (control group) or a cervicothoracic plus lumbopelvic program (experimental group). The CV angle, neck disability index (NDI), and normalized electromyography as a percentage of maximum voluntary isometric contraction (%MVIC) from spinal muscles were measured before and after the intervention.

Results

Post-intervention, both groups showed significant improvement across time in CV angle and NDI (p < 0.001, p = 0.002). However, the between-group comparison was not statistically significant. The NDI showed significant improvement only in the experimental group (p = 0.005). The minimal clinical important difference (MCID) obtained was 6.44 for the NDI. A reduction in %MVIC over time was observed in both groups for cervical erector spinae (Right, p = 0.006, Left, p = 0.001). The between-group comparison of spinal muscle activation was not significantly different.

Conclusion

The study suggested that FHP management using a cervicothoracic or cervicothoracic plus lumbopelvic protocol could improve cervical posture and lower cervical muscle demand. Incorporating a lumbopelvic into the cervicothoracic protocol was more effective in reducing short-term neck pain and disability than a cervicothoracic protocol alone. A comprehensive spine program may be a clinically beneficial rehabilitation protocol for FHP to improve neck pain and disability.
