Methods: This was an open-label, prospective study involving 100 subjects with symptoms of back pain and muscle spasm.Eligible participants were randomly allocated to an experimental group (54 patients) and a control group (46 patients).The experimental group received eperisone Training Gloves 50 mg three times daily + ibuprofen 400 mg twice daily, and the control group received ibuprofen 400 mg twice daily over a 4-week duration.The primary outcomes were measured with the visual analog scale (VAS), and finger-to-floor (FTF) distance at baseline, week 2, and week 4.Results: After 4 weeks of follow-up, results from 59 subjects were collected.

In both groups, VAS and FTF were decreased compared to baseline.Clinically significant pain reduction (> 50% than baseline) was observed to be higher in the experimental group compared with the control group in the fourth week (72.4% vs 46.7%, P< 0.05).

At the end of SKIN LIGHTENING the study, pain reduction in the experimental group was more significant compared to the control group (28.13± 24.72 vs 34.42± 28.47) and participants mobility (FTF distance < 10 cm) improved in both groups, especially in the experimental group (75.

9% vs 70%).There was no difference in adverse events between groups (P> 0.05).Conclusion: The combination of eperisone hydrochloride and ibuprofen effectively reduces pain and improves functional outcomes over ibuprofen alone with a similar safety profile in these patients with acute non-specific back pain with muscle spasm.Keywords: low back pain, eperisone hydrochloride, pain reduction, comparison.
