Analysis of Forward Trunk Bending in Women with Chronic Low Back Pain Undergoing Functional Training

Background/Objectives: This paper analyzes the movement and relationships within the lumbopelvic-hip complex during forward trunk bending in young women with chronic low back pain. Methods: This study involved 24 women aged 20-24 with chronic low back pain. They were randomly divided into two equal-sized groups: Group 1 participated in a 12-week functional training program, and Group 2 was a control without any intervention. The level of perceived pain was assessed using the Visual Analog Scale (VAS). Qualitative motion analysis was performed using the BTS SMART-D system. Custom indicators were developed to evaluate the angular relationships and ranges of motion in the lumbar spine and the lumbopelvic-hip complex. The functional training program consisted of three sections: motor control and stabilization, muscle strengthening, and stretching exercises. Statistical analysis was performed using Statistica 13.3. Results: The therapy resulted in a reduction in perceived pain levels reported by the participants. There was a significant improvement in the quality of the forward trunk bending pattern in women who underwent functional training. Conclusions: Significant modifications in the quality, technique, and angular relationships within the lumbopelvic-hip complex were observed during the forward trunk bending pattern in women undergoing functional training. It has proven to be an effective form of therapy for chronic low back pain.
