The Efficacy of Lumbar Traction versus Spinal Mobilization with Leg Movement in Patients with Lumbar Radiculopathy: A Randomized Controlled Trial

Résumé

Background and Purpose Spinal mobilization with leg movement and lumbar traction are individually recognized as evidence-based treatments for lumbar radiculopathy. However, previous studies have not compared these two modalities directly. This study aimed to compare the effects of lumbar traction versus spinal mobilization with leg movement on pain, range of motion, and disability in adults with lumbar radiculopathy. Materials and Methods In this randomized controlled trial, (n=60) patients diagnosed with lumbar radiculopathy by their orthopedist participated in this study. They were randomly divided into three groups: Experimental group (a) consisted of 20 patients who received LT and conventional treatment; Experimental group (b) consisted of 20 patients who received spinal mobilization with leg movement and conventional treatment; Control group (c) consisted of 20 patients who received only conventional treatment (ultrasound therapy, hot packs, and core stability exercises). Interventions were conducted over 12 sessions (3 sessions per week) across four weeks. Outcomes were assessed at the start and end of the fourth week using a visual analog scale (VAS) for pain intensity, the Oswestry Disability Index for functional disability, and a back range of motion (BROM) device to measure lumbar spine flexion and extension. Results All groups showed significant improvement post-treatment compared to pre-treatment (P<0.05) across all measured variables. Group analysis revealed significant differences among the three groups in visual analog scale and Oswestry Disability Index scores (P=0.001), with groups A and B showing greater improvement than group C. However, there were no significant differences between the groups in back range of motion measurements (P>0.05). Conclusion Both spinal mobilization with leg movement and lumbar traction were effective in managing patients with lumbar radiculopathy. However, there was no significant difference in effectiveness between the two treatments.
