Abstract
[Objective] This study established guidelines for treatment and proposed more specific treatment methods for low back pain(LBP). [Method] Participants suspected LBP due to piriformis contracture were 8 athletes of Passive Therapy (PT) group who received only PT once a week for six consecutive times and 8 athletes of PT+Active Exercise Therapy(AET) group who performed daily active exercise(DAE) in addition to PT. The elasticity of piriformis muscle was measured before and after treatment using ultrasound-elastography. The examinations of SLR, FABER, and NRS were developed to enable comparison between participants’ scores before and after each PT, same as in comparison to PT+AET and PT group’s scores, in order to examine efficacy of PT and DAE. [Results] There were significant differences in the elasticity, SLR, FABER, and NRS values between values before the first treatment and values before treatment 3 weeks later in PT+AET group. In PT group, values 1 week later returned to values before the first treatment. [Discussion Conclusion] This study clarified that the measurements’ values 1 week later of athletes who received only PT returned to values before the first treatment. However, it is expected to make a significant progress toward cure of LBP in 2 weeks by adding DAE.
