초록

Purpose : The purpose of this study was to analyze the effects of proprioceptive neuromuscular facilitation (PNF) leg flexion patterns according to the hip joint angle on electromyographic activity of the trunk. Methods : Thirty healthy adults volunteered to participate in this study. Subjects were required to complete following the PNF leg flexion patterns on three different hip joint flexion $30^{\circ}$, $60^{\circ}$ and $90^{\circ}$. An surface electromyogram (SEMG) was used to record the electromyographic activities of the trunk muscle in rectus abdominis, internal oblique abdominal, external oblique abdominal, erector spinae. The data were analyzed using the a repeated measures of one-way ANOVA with post-hoc Bonferroni's correction. Result : The results of this study are summarized as follows: The EMG activities of internal abdominal oblique and elector spinae muscle showed a statistically significant difference (p<.05). Conclusion : The result show that electromyographic activity of the trunk muscles significantly changed on PNF leg flexion patterns with difference hip joint angle. Therefore, this study used to basis for the intervention of the trunk muscle strength and stabilization.
