ABSTRACT

Objectives :The purpose of this study was to investigate the effect of EST(electrical stimulation therapy) on trunk flexors and extensors. Methods :33 normal participants participated in this study. The muscle power of trunk flexors and extensors of each participant was tested before and after applying 15 minutes of EST on low back, using Cybex HUMAC NORM. Results :1. The average power of trunk extensors increased by 19.47±30.69, from 255.11±85.80 to 274.58±95.72(p<0.05) after applying EST on low back(Table Ⅳ), which was statistically significant. 2. The average ratio of trunk flexors and extensors decreased by 5.82±13.95, from 68.61±20.48 to 62.79±16.25(p<0.05) after applying EST on low back(Table Ⅵ), which was statistically significant. 3. The average power of trunk flexors insignificantly decreased by 1.83±30.39, from 168.47±57.27 to 166.64±55.441(p>0.05) after applying EST on low back(Table Ⅴ), which was not statistically significant. Conclusions :These results suggest that EST strengthens the muscle power when applied on trunk extensors.
