The paper presents an analysis of the loads acting on lumbar spine during movement of sitting down and getting up from a chair. The study was conducted on a group of 30 people (parents of disabled children) complaining about chronic low back pain. Basing on kinematics, obtained during experiment from APAS system, simulations were performed in the Anybody Modeling System environment. The use of methods, mathematical modeling and static optimization, allowed to determine the magnitude of the loads acting on musculoskeletal system. The results of reactions in the L5-sacrum joint, the muscular forces of erector spinae and the transversus abdominis are significantly correlated with the kinematics of the movement.

The study was conducted within 3 Year Healthy Community Project conditioned upon Special Olympics Poland (Olimpiady Specjalne Polska). Grant was approved and financed by Special Olympics Inc. on 25th April 2016.
