Elastic resistance exercises for prevention of trunk deformities - a case study

Subjects and methods The present pilot study is a case report on a single proband. Surface EMG (Noraxon) was recorded on one healthy subject during 3 resistive exercises using TheraBand (blue color). EMG activity during the agistic-excentric-exercises was analyzed on m. obliquus abdominis int., m. rectus abdominis, m. latissimus dorsi, m.erector spinae TH-L on the right and left side. The EMG activity was analyzed and compared with MVC. Results were examined by exercise for improvement of the function of trunk lateroflexion, rotation, and frontal shift of thorax, and this was documented with EMG-activity in m. latissimus dorsi 4% MVC 24% MVC, in m. obliqus abd. int. 6% MVC 73% MVC, in m. erector spinae Th-L 1% MVC 52% MVC and in m. rectus abdominis 2% MVC 3% MVC. During the exercises, increases and decreases in EMG activity were seen in analyzed muscles. Detailed results will be described in the presentation.
