IMPACT OF STRENGTHENING OF THE ERECTOR SPINAE MUSCLE ON THE VALUES OF LOADS OF THE MUSKULOSKELETAL SYSTEM IN THE LUMBAR SPINE SECTION

pages 718 - 721, full text

This work aimed to determine resultant changes of reactions in the lumbar spine section (L5Sacrum) influenced by strengthening of the erector spinae (spinal erectors) muscle. Identification of the loads of the musculoskeletal system was conducted by means of a mathematical model of the human body created in the Anybody Modeling System environment. The results of the measurements of kinematics were used as input data. Strengthening of the muscle was simulated by increasing a maximum isometric force which could be generated by a single muscle by means of increasing its physiological cross section. On the basis of the performed calculations, it was observed that the increase in the cross section of the transverse erector spinae muscle causes the increase of reactions in the L5-Sacrum joint, simultaneously lowering the strength of the transverse abdominal muscle and the value of the intra-abdominal pressure. Conclusions resulting from this research may be used in physiotherapeutic practice for the selection of exercises which aim to reduce pain ailments in the lumbar spine section.
