Effects of cervical stabilization with visual feedback on craniovertebral angle and proprioception for the subjects with forward head posture.

ABSTRACT

BACKGROUND: This study aimed to identify the effect of cervical stabilization exercise with visual feedback on the craniovertebral angle and proprioception in subjects with forward head posture. METHODS: Thirty healthy adults were recruited in the study. Participants were randomly assigned to the stabilization exercise with visual feedback (SE-VF) group (N = 15) or stabilization exercise group (N = 15). The SE-VF group performed cervical stabilization exercise while sitting on a chair without a backrest and checking their side profile in real-time via a monitor 3-m away. The stabilization exercise group performed the same cervical stabilization exercise as the SE-VF group but without visual feedback. Craniovertebral angle (CVA) was measured to quantify forward head posture, and the proprioception of the subjects was evaluated. RESULTS: There was a significant interaction between group and time in CVA and proprioception (P < .05). Additionally, there was no significant difference pre-intervention between the groups (P > .05); however, there was a significant difference post-intervention (P < .05) in CVA and proprioception. CONCLUSION: The findings of this study showed that the cervical stabilization exercise with visual feedback was effective for the proprioception of subjects. Moreover, the results suggest that visual feedback is effective in cervical stabilization exercise.
