Purpose : We aimed to investigate the effect of cranio-cervical flexion exercises(CCFE) with visual feedback(VF) on the muscle activity of the upper trapezius in forward head posture (FHP) and whether deficits in proprioception affect the changes in muscle activity. Methods : Twenty subjects with FHP were assigned to one of 2 groups according to deficits in proprioception. The muscle activity of the upper trapezius during arm movement under three exercise conditions (resting, CCFE, and VF + CCFE). Repeated-measures analysis of variance was used to compare differences in muscle activity according to the exercise conditions between the groups and to analyze the interactions between groups and conditions. Results : Significant differences were observed in muscle activity according to the exercise condition (p<.05), with no significant differences between the groups. The muscle activity of the upper trapezius was significantly different between the resting and VF +CCFE conditions (p<.05), with no significant difference between the resting and CCFE conditions (p>.05). Conclusion : The results of this study showed that the CCFE combined with VF are an effective intervention for FHP to train deep muscles selectively. In addition, the loss of proprioceptive sensation is not related to changes in muscle activity during exercises.
