Psoas Muscle Index And Psoas Muscle Density Are Associated With Functional Status In Patients With Degenerative Lumbar Spinal Stenosis London Spine Lumbar Stenosis

This article discusses the factors affecting lumbar spinal function in patients with degenerative lumbar spinal stenosis (DLSS) and the association of psoas major muscle morphology with their functional status. The study conducted a retrospective analysis on 288 patients with DLSS and 260 control subjects. The evaluation of psoas major muscle included three morphometric parameters, and the association with functional status was assessed using the Oswestry disability index (ODI). The results showed that both female and male patients with DLSS had higher psoas major index (PMI) and lower muscle attenuation. PMI and muscle attenuation were also found to be positively correlated with functional status in patients with DLSS. These findings have important implications for physiotherapy programs and conservative management strategies for DLSS

Abstract

Background: The factors affecting lumbar spinal function in patients with degenerative lumbar spinal stenosis (DLSS) are still unclear.

Objective: This study explored psoas major muscle morphology in patients with DLSS and its association with their functional status.

Methods: A retrospective study was conducted on 288 patients with DLSS and 260 control subjects. Psoas major muscle evaluation included three morphometric parameters at the L3/4 disc level: psoas major index (PMI), muscle attenuation, and psoas major morphological changes (MPM). The association between psoas major morphology and functional status was assessed using the Oswestry disability index (ODI).

Results: Both female and male patients with DLSS had a higher PMI and lower muscle attenuation. PMI and muscle attenuation were inversely correlated with age in the DLSS group. After multivariable analyses, the PMI and psoas major muscle attenuation were positively correlated with patients’ functional status.

The PMI and muscle attenuation were positively correlated with functional status in patients with DLSS. These findings have important implications for physiotherapy programs of postoperative rehabilitation and conservative management of DLSS.

Keywords: Degenerative lumbar spinal stenosis; functional status; morphology; oswestry disability index; psoas major muscle.
