Activation asymmetry of the lateral abdominal muscles in response to neurodevelopmental traction technique in children with pelvic asymmetry

Abstract Study aim : The of the study was to evaluate asymmetry activation lateral abdominal muscles (LAM) in response neurodevelopmental traction technique children with pelvic asymmetry. Material and methods Measurements LAM were performed during force 5% body weight two experimental conditions: 1) neutral position, 2) 20° posterior trunk inclination. Twenty-three healthy participated study. To ultrasound technology employed (two Mindray DP660 devices (Mindray, Shenzhen, China)). Activation indices for each individual calculated. Results magnitude indexes formed a gradient, most profound transversus abdominis (TrA) showing greatest asymmetry, superficial obliquus externus – smallest. inter-muscle differences pronounced between TrA more oblique muscles. There no correlation Conclusions During there is difference symmetry, deeper greater does not seem be associated are similar those recorded earlier studies samples where subjected analysis.
