AB - PURPOSE: This study examined the effects of stabilization exercises utilizing electromyography (EMG) light feedback on correcting the forward head posture and assessed the changes in cervical muscle characteristics.
METHODS: Thirty-one adults with a forward head posture were divided randomly into two groups. One group performed stabilization exercises with EMG light feedback, while the other group performed conventional stabilization exercises. The cervical angles and cervical muscle characteristics were measured before and after the intervention.
RESULTS: The results showed no significant differences or interactions between the groups and over time in CVA and CRA. The SCM muscle tone increased significantly over time in the experimental group, with notable differences compared to the control group at the mid and post measurements. The SCM stiffness showed significant time-dependent changes only in the experimental group. The upper trapezius muscle tone exhibited significant changes over time in both groups, with group differences observed at the mid and post-intervention points. The stiffness of the upper trapezius also changed significantly over time in both groups, but no significant differences between the groups were found at any time point.
CONCLUSION: The muscle characteristics showed significant improvement in the SCM only in the experimental group, while the upper trapezius improved in both groups, due likely to the effective activation of deep neck flexors through EMG light feedback exercises.Feedback-based stabilization exercises are effective for neck muscle function recovery and balance, and future studies should investigate the long-term effects of habitual posture correction.
