Disc Hydration Response to Simulated Stooped and Erect Postures

Abstract

Evidence suggests that prolonged exposure to stooped work is associated with the development of low back disorders, particularly those that affect the spinal intervertebral discs. While several studies have been done to analyze the biomechanical aspects of stooped work, very little research has focused on the effect of prolonged stooped work on disc hydration- a critical component of disc health. This study explores the connection between stooped work and low back pain through controlled mechanical loading and quantitative analysis of disc hydration during in vitro simulated stooped and erect loading conditions of porcine discs. The results showed that stooped postures exhibit significantly decreased overall water content relative to erect postures. These results have implications for the injury mechanisms associated with stooped work, as disc hydration forms the foundation for overall disc health and proper function.
