Application of hot medicated fomentation for pain alleviation in non-specific low back pain - A randomized controlled clinical trial

Abstract

BackgroundNon-specific low back pain is a leading contributor to disease burden and works absenteeism worldwide with a lifetime prevalence of 60–70% in industrialized countries. This clinical study aimed to assess the efficacy of hot fomentation with half-baked medicated bread (khubz) compared to hot water bag fomentation to alleviate pain and disability in non-specific low back pain. MethodsIn this randomized-controlled study, fifty-four patients with low back pain were randomly assigned into two groups to receive either hot fomentation (Takmīd-e-haar) with half-baked medicated bread in the test group or hot water bag fomentation in the control group, on the lumbosacral region daily for 30 min for 15 consecutive days. Patients were assessed statistically using the visual analogue scale (VAS) and Oswestry disability index (ODI) at baseline, 7th and after treatment (15th day). ResultsAfter the intervention, statistically significant improvements (p < 0.001) were observed in VAS and ODI scores in both the groups on the intragroup comparison. The test treatment showed better efficacy in comparison to the control treatment with a mean difference of 1.75 in VAS (p < 0.0001) and 8.20 in ODI (p = 0.001). ConclusionThe tested intervention showed significantly better efficacy in comparison to the hot water bag fomentation probably due to the analgesic (musakkin-i-alam), anti-inflammatory (muḥallil-i-awrām), and demulcent (mulaṭṭif) properties of the ingredients of tested Unani formulation in addition to the effects of heat. It may therefore be concluded that medicated fomentation is an effective, safer, feasible, and less expensive regimen for patients with non-specific low back pain.
