摘要：Introduction and objectives. The vertical orientation of the body in the upright standing position is maintained by keepingthe body’s centre of gravity (COG) upright, above the base of support, by a dynamic interplay of visual, vestibular, andsomatosensory control systems. The objectives of this study were: to compare the postural control strategy between peoplewith and without low back pain (LBP), to estimate the influence of the stretching therapy on the postural control strategy,and to discover the relationship between the restriction of spine mobility and occurrence of some ergonomic factors.Materials and methods. The study consisted of 32 patients with LBP and 25 healthy controls. Postural characteristics ofthe subjects were measured with the use of a computerized force platform. The software programme filters and measuresCOG sway velocity in different conditions. Additional measurements and tests were conducted in patients after stretchingtherapy. Based on survey research, all individuals were selected and evaluated from the aspect of ergonomics.Results. The results of the COG sway velocity vary under the testing conditions. From the aspect of ergonomic attitudeand influence of the rehabilitation, results varied in the groups.Conclusions. Ergonomic factors are often accompanied by the appearance of LBP. The restrictions within the musculoskeletalsystem cause disorders in muscle synergies, which is expressed by an increase in the angular velocity of the COG. In patientswith chronic back pain syndrome, selected stretching therapy techniques improves the range of motion of the spine andreduces pain.
