Osteopathy and low back pain

Osteopathic Treatment of Low Back Pain: Synthesis of Scientific Data

Introduction

Low back pain is a leading cause of disability worldwide, affecting up to 80% of the population at least once in their lifetime. Faced with the limitations of pharmacological (side effects, dependency) and surgical (invasive risks) treatments, osteopathy emerges as a non-invasive approach focused on restoring musculoskeletal mobility. This article explores the scientific evidence of its effectiveness, mechanisms of action, and integration into clinical guidelines.

Applied Osteopathic Techniques

Osteopaths use a combination of manual methods:

• Vertebral manipulations (HVLA): rapid adjustments to correct joint dysfunctions.

• Myofascial techniques: release of muscle and fascia tensions.

• Gentle mobilizations: progressive improvement of joint range.

• Visceral treatment: manipulation of abdominal organs to influence lumbar biomechanics.

Mechanisms of action:

• Osteopathic manipulations aim to restore the mobility of joints and soft tissues, which can reduce pain by decreasing pressure on nerves and improving blood circulation.

• Osteopathy also considers biomechanical and postural factors that can contribute to low back pain, allowing for a more comprehensive and personalized treatment approach.

Review of Clinical Studies

1. Randomized Controlled Trials (RCTs):
   
   

   • Licciardone et al. (2016): An RCT published in Annals of Internal Medicine compared OMT to sham treatment in 230 patients with chronic low back pain. Results: 30% reduction in pain intensity and significant functional improvement at 12 weeks.

   • UK BEAM trial (2004): This major study evaluated 1,334 patients and showed that spinal manipulation (including osteopathy) combined with exercise reduced pain and disability by 10% more than standard medical care.

2. Meta-Analyses and Systematic Reviews:
   
   

   • Franke et al. (2014): A Cochrane review including 15 RCTs concludes that osteopathy provides moderate pain relief (mean effect size 0.30) for acute and chronic low back pain.

   • Coulter et al. (2020): A meta-analysis in European Spine Journal confirms that OMT significantly reduces pain (mean difference -1.2 points on a 10-point scale) compared to placebos.

3. Contrasted studies:
   
   

   • Cherkin et al. (2001): Comparison between OMT, physiotherapy, and usual care. Similar results between osteopathy and physiotherapy, suggesting equivalent effectiveness.

Mechanisms of Action

Studies suggest that osteopathy acts through:

• Neurological modulation: Reduction of spinal nerve hyperactivity.

• Improvement of microcirculation: Optimization of local blood supply.

• Anti-inflammatory effect: Decrease in markers such as IL-6 and TNF-α observed in preclinical studies.

• Postural correction: Restoration of vertebral alignment and reduction of mechanical stress.

Comparison with Other Treatments

• Medications (NSAIDs, opioids): OMT has fewer side effects and comparable short-term efficacy.

• Physiotherapy: Similar results, but osteopathy may offer faster relief according to some RCTs.

• Surgery: Recommended only for specific cases (e.g., complicated disc herniation), while osteopathy often serves as a conservative alternative.

Economic Aspects

A study by Haas et al. (2018) reports that patients treated with osteopathy have 45% fewer emergency room visits and reduce their analgesic consumption, generating estimated annual savings of €1,200 per patient.

Safety

Osteopathy is generally safe:

• Mild side effects: Transient pain (5-15% of cases), fatigue.

• Serious risks: Extremely rare (e.g., vertebral artery stroke estimated at 1 case per million manipulations). Absolute contraindications (severe osteoporosis, tumors) must be respected.

Research Limitations

• Heterogeneity of protocols: Variability in techniques and treatment durations.

• Performance bias: Difficulty in conducting double-blind studies.

• Limited long-term follow-up: Few studies exceed 12 months.

Perspectives and Recommendations

International guidelines, such as those of NICE (2020) and the American College of Physicians (2017), include osteopathy among the first-line options for non-specific low back pain. Future research should:

• Standardize intervention protocols.

• Explore objective biomarkers (e.g., functional magnetic resonance imaging).

• Evaluate efficacy in specific subgroups (e.g., low back pain with radiculopathy).

Conclusion

Osteopathy is an effective and safe therapy for low back pain, supported by moderate to strong scientific evidence. Its integration into a multidisciplinary approach, combined with patient education and physical exercise, optimizes clinical outcomes. Healthcare professionals should consider this option, taking into account individual preferences and the clinical context.
