The Effectiveness of Lumbar Regression Technique on Disc Bulge: A Randomized Controlled Trial

Background: Lumbar disc bulge is a prevalent cause of low back pain (LBP), contributing significantly to disability and healthcare costs. Innovative non-surgical treatments are required to address the limitations of traditional physical therapies.Objective: This study aimed to evaluate the effectiveness of lumbar regression techniques compared to standard physiotherapy in improving flexibility, reducing disability, and managing pain in patients with lumbar disc bulges.Methods: A randomized controlled trial was conducted with 24 participants diagnosed with lumbar disc bulge. Participants were divided into two groups: the experimental group (Group A) received lumbar regression techniques, and the control group (Group B) received standard physiotherapy. The interventions lasted for 8 weeks, with outcomes measured using the Straight Leg Raise (SLR), Roland-Morris Disability Questionnaire (RMD), and Visual Analogue Scale (VAS) at baseline and post-intervention.Results: Group A demonstrated a significant improvement in SLR (baseline: 70.0 ± 8.0, 8th week: 85.0 ± 7.0; p=0.004), RMD (baseline: 15.0 ± 4.5, 8th week: 10.0 ± 3.0; p=0.032), and VAS scores (baseline: 7.0 ± 1.5, 8th week: 3.0 ± 0.6; p=0.026) compared to Group B.Conclusion: Lumbar regression techniques significantly improved flexibility, reduced disability, and alleviated pain in patients with lumbar disc bulge more effectively than standard physiotherapy.
