Analysis of the impact of lumbar lordosis on selected balance parameters in women

Introduction
Scientific research in the literature confirms a direct influence and relationship between increased parameters of lumbar lordosis of the spine, and changes and deviations from the norm within equivalent reactions.

Aim of the research
The aim of the study was to analyse selected parameters in a group of women based on their depth of lumbar lordosis.

Material and methods
The research was carried out from January until October 2023. The study group totalling 75 women consisted of female students of the Collegium Medicum, aged 18–26 years. The tests were carried out in a static form using the DIERS Posture Lab system. The following parameters were fed into the calculation sources: “lordosis angle”, “pelvic inclination”, “CoP lateral movement”, “COP area”, “CoP total anterior/posterior movement”. In addition, the following Harzmann parameters were considered: “lateral deviation”, “surface rotation”, “pelvic obliquity”, “pelvic torsion”, “vertical deviation” and foot load parameters: “rear force distribution”, “front force distribution”, “left side force distribution”, “right side force distribution”, “maximum pressure on the left side”, “maximum pressure of the right side”, “contact area of left feet”, “contact area of right feet”.

Results and conclusions
There was no statistical significance of correlation between lordosis and equivalent reactions and pelvic tilt in the group of young adult women. The impact of lumbar lordosis on young adult women does not directly affect the tested parameters. The parameter of the lordosis angle and pelvic inclination were higher than usual; therefore, the distribution of forces in the foot was also characterised by a different load distribution.
