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

## TL;DR

This study shows that functional training improves movement patterns and reduces pain in young women with chronic low back pain.

## Contribution

The study introduces a functional training program that effectively modifies lumbopelvic-hip movement during forward bending.

## Key findings

- Functional training significantly reduced perceived pain levels in participants.
- Women who underwent training showed improved forward trunk bending movement quality.
- Training led to significant changes in angular relationships within the lumbopelvic-hip complex.

## Abstract

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.
