Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This pilot study aims at styding the correlations between body mass index, waist circumference and the potential for positional adaptation of the pelvis to support overweight or obesity

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Record cards of patients presenting with non specific low back pain between January 1st 2020 and December 23rd 2022 were analysed.

All included patients had undergone a full spine X-ray allowing to calculate the pelvic index (PI). Weight status was described in 4 categories, in-line with the WHO definitions; Underweight (boddy mass index (BMI)) \< 18.5 kg/m²; normal weight BMI 18.5 - 24.9 kg/m² , overweight BMI 25 - 29.9 kg/m², and obesity BMI ≥ 30 kg/m². To identify people with increased BMI-values and central (abdominal) fat distribution, we used the waist circumference (WC). The cut-off points of waist measurement that are used are 102 cm and 88 cm for men and women respectively. A high sacral slope (SS) means a greater the lumbar curvature, which results in a dynamic back. Due to the correlation between SS and PI, people with high PI values generally have higher values of SS. Therefore types 1 and 2 have a low-grade PI and types 3 and 4 have a high-grade PI Analysis of 272 patient records, shows that the mean PI is significantly different in the group with a low WC compared with the group with a high WC. BMI and WC show a significant correlation with PI
