EVALUATION OF SPINE STABILITY IN LOW BACK PAIN USING SPINAL MOUSE

Abstract

Background: Chronic low back pain (CLBP) is frequently associated with impaired spinal mobility and segmental instability. Aim: This study aimed to assess lumbar spinal stability in patients with CLBP using the Idiag M360 device, a non-invasive tool for objective evaluation of spinal motion. Methods: Sixty-three patients (mean age 38.6 years) were evaluated through a standardized protocol involving three test positions: neutral posture, forward flexion, and the Matthiass test. Parameters analyzed included curvature angles, segmental mobility, sagittal asymmetry, and the lumbar spinal stability index (ISSi). Results: The mean ISSi was 56.06 ± 23.68, with 32 patients scoring below 60, suggesting potential functional instability. The high interindividual variability highlights the heterogeneity of neuromuscular control among patients with CLBP. Conclusion: The Idiag M360 is an effective tool for detecting subtle segmental dysfunctions and spinal instability. Its ability to provide quantitative data facilitates personalized therapeutic planning and progress monitoring in physical rehabilitation.
