Purpose : The purpose of this study was to investigate the difference in motor cortical excitability during mental practice and action observation in subjects with forward head posture. Methods : This study was performed in two groups, a forward head posture group (n=17) and a normal posture group (n=17). Electroencephalography (EEG) was conducted to investigate cerebral cortex activity, and six electrodes were attached to Fp1, Fp2, C1, C2, C3, and C4 to measure the relative alpha power, relative beta power, relative gamma power, and mu rhythms. The subjects were requested to perform the four different conditions, which were eye opening, eye closing, mental practice, and action observation for 300 seconds. Results : The results showed that the relative alpha waves showed a significant difference between the normal and forward head posture groups in the C1, C2, C3, and C4 regions with the eyes open (p<.05). The relative beta waves also showed a significant difference between the two groups in the Fp1 and Fp2 regions during action observation (p<.05). The relative gamma waves were significantly different between the normal and forward head posture groups in the Fp1 and Fp2 regions during action observation (p<.05) in C1, C2, and C3 with eyes closed (p<.05) and in C1, C2, C3, and C4 with eyes open (p<.05). Conclusion : The results of this study showed that EEG change in the forward head posture group was different from that in the normal control group in action observation rather than in mental practice. Therefore, we are expected to provide a neurophysiological basis for applying action observation to motor skill learning during exercise for correcting forward head posture. Purpose : The purpose of this study was to investigate the difference of motor cortical excitability during mental practice and motion observation in subjects with forward head posture. Method : This study was performed on the two groups; forward head posture(n=17) and normal(n=17). Electrocephalography was conducted for the investigation of the cerebral cortex activity and the sixth electrodes were attached to Fp1, Fp2, C1, C2, C3, C4 in order to measure the relative alpha power, the relative beta power, the relative gamma power, and mu rhythms. The subjects were requested to perform the four different conditions, which were eye-opening, eye-closing, mental practice, and action observation for 300 seconds. Result : The results showed that of the relative alpha waves were a significant difference between the normal group and the forward head posture group in the C1, C2, C3, and C4 regions in the eye open(p<0.05). The relative beta waves were a significant difference between the normal group and the forward head posture group in the Fp1 and Fp2 regions during motion observation(p<0.05). Relative gamma waves were significantly different between the normal group and the forward head posture group in the Fp1 and Fp2 regions during motion observation(p<0.05), in C1, C2, and C3 in the eye closed(p<0.05), C1, C2, C3, and C4 regions in the eye open(p<0.05). Conclusion : The results of this study showed that EEG change in the forward head posture group was different from that in the normal control group when motion observation than mental practice. Therefore, we are expected to provide neurophysiological basis for applying motion observation to motor skills learning when exercising for correcting forward head posture.

Purpose: The purpose of this study was to investigate the effects of three exercise programs on forward head posture. Methods: Ninety-five individuals were recruited to assess the of the pectoralis minor muscle. Of these, 36 individuals with pectoralis minor muscles were selected and randomly divided into three groups: a functional massage group, a stretching group, and a stretching and muscle strengthening group. The exercise program consisted of sessions four times per week for two weeks. The length of pectoralis minor and the activity of the trapezius muscles were measured using electromyography. Forward head posture was assessed using the craniovertebral angle (CVA) and the cranial rotation angle (CRA) pre-, during and post-treatment. Result: Significant improvements were observed in pectoralis minor length, CRA, and CVA post-treatment in all groups (p<0.05, p<0.01, p<0.001). However, only the activity of the lower trapezius demonstrated a statistically significant difference post-treatment. There were no significant differences between the groups. Conclusion: The findings of this study suggest that all three exercise programs were effective in improving forward head posture and the length of pectoralis minor post-treatment.
