Abstract

Purpose: Forward head posture is one of the most prevalent poor postures that cause neck injuries. The objective of this study was to investigate the electrical activity of selected muscles during Running in an able-bodied control group and in boys with Forward head posture. Methods: Twenty eight boys were volunteered to participate in this study. The subjects divided into a healthy control group (n=16) and a group of boys with Forward head posture (n=12). A portable EMG system was used to record the electrical activity of the bilateral seratus anterior, erector spinae (cervical part), sternocleidomastoid, and upper and lower trapezius muscles during barefoot Running. For EMG analysis, the average root mean square (RMS) values of the three trials were calculated and then normalized based on the peak RMS obtained by the maximum isometric voluntary contraction. Independent sample t-test was used for between group comparisons. The significance level was set at p<0. 05 for all analyses. Results: The findings indicated that Running speed in boys with Forward head (2. 70± 0. 09 m/s) was smaller than that in control group (2. 91± 0. 14 m/s) (p<0. 001). The activity level of all selected muscles were not statistically different between both groups (p>0. 05). However, Asymmetry index of electrical activity of sternocleidomastoid muscle in control group was greater than that in Forward head posture group by 8. 3± 1. 5% (p=0. 045). Conclusion: In boys with Forward head posture the Running speed was reduced and the muscle activity was similar with respect to those in control group. This altered Running speed and muscle activity is suggestive of a lower mechanical efficiency of Running in boys with Forward head posture that is consistent with literature.
