Functional Patterns and Postural Balance in Young Women With Chronic Non-Specific Low Back Pain and Healthy Individuals

Introduction In the case of chronic low back pain, changes occur at the central nervous system level. It leads to functional limitations, muscle activity, and motor control impairments.Objectives The aim of the study was to analyze the impact of chronic low back pain on the quality of performance functional patterns and postural balance in young women.Material and methods The study involved 60 women with an average of 21.571.07. In Group 1 (n=30), participants reported chronic low back pain, Group 2 (n=30) was the control group. To assess functional efficiency, the Functional Movement Screen was used. Postural stability was evaluated using the FreeMED Posture Base pedobarographic platform. Pain level was determined using the VAS scale, and pelvic anterior tilt was measured using the BROM II.Results In the group of women with chronic low back pain, significantly lower levels of functional efficiency were observed. The length distance covered by the CoP, the area of an ellipse containing the trajectory of the CoP, and the average velocity of the CoP were greater compared to the group of women without pain. In Group 1, significantly greater asymmetry in foot pressure distribution was noted.Conclusions Individuals reported chronic low back pain demonstrate poorer quality of performance functional patterns and postural stability compared to healthy ones. Detecting movement disorders may contribute to a physiotherapist's planning of a therapeutic program that includes the specific movement deficits of patients. It can directly impact the reduction or delay of pain occurrence.
