Effect of Sling Neck Flexion Exercise on Concentration and Brain Activity of Subjects with Forward Head Posture

Background/Objectives: The purpose of this study was to investigate the effect of sling neck flexion exercise on attention and brain activity in subjects with forward head posture (FHP). Method/statistical Analysis: The study group comprised 30 students who were randomly divided into two groups. One group(15 students) took part in sling neck flexion exercise for 6 wk, and the other group(15 students) served as the control. FHP was determined using a global postural system (GPS 400) device. An electroencephalogram (EEG) was performed using EEG 3000 to assess left and right brain activity. Findings: A homogeneity test revealed that the general characteristics of the subjects in the two groups did not significantly differ. A paired t-test and independent t-test were performed to analyze differences between and within two groups. The change in concentration according to the experiment duration showed a significant difference in the experimental group (p<.05). By contrast, the control group showed no significant difference (p>.05). While the change in the left brain activity showed a significant difference in the experimental group (p<.05), the control group did not show a significant difference (p>.05). The mean at each time period showed no significant difference between the two groups (p>.05). While the experimental group showed a significant difference in the change in the right brain activity according to the experiment duration (p<.05), no significant difference was observed in the control group (p>.05). The between-group difference of the mean at each time period showed no significance (p>.05). Improvements/Applications: In conclusion, sling neck flexion exercise can improve brain function. Regular postural correction exercise is required. We expect the results to be used in clinical trials.
