Mézières Method as a practice of embodiment in patients with low back pain: a mixed study

INTRODUCTION: The objectives of this study were to determine the effects of the Mézières Method (MM) on pain and disability related to low back pain (LBP), compared to a program of heat, massage and exercise, and to understand the meaning of the bodily experience with the MM. PATIENTS AND METHODS: Mixed methods convergent parallel design, combining an equivalent randomized clinical trial with a qualitative phenomenological approach. Sixty-one participants aged 18–65 years with chronic non-specific LBP lasting more than 3 months. Patients were randomized into two groups: the MM group (n = 29) and the comparison group (CG) who received heat, massage plus flexibility and strengthening exercises (n = 31). MM and CG participants underwent 10 one-hour physical therapy sessions over a 5-week period and were evaluated three times: pre-intervention, post-intervention and follow-up at 6 weeks after the end of treatment. RESULTS: Both groups reported positive effects on LBP . MM group showed superior effects in pain relief in the short term (Cohen’s D 0.80; p = 0.004). Participants interpreted the interaction with the MM as a teaching–learning process that allowed body awareness. CONCLUSION: Both treatment were similarly beneficial but MM had superior effects on pain in the short term. MM is perceived by the participants as a teaching–learning process focused on body awareness that facilitate effective management of LBP.
