Comparing the efficacy of Agnikarma with therapeutic ultrasound in the management of tennis elbow - A randomised controlled preliminary study

Background

Tennis elbow is a common musculoskeletal disease of elbow and causes restricted movement of forearm. Various treatment modalities like NSAID, corticosteroid injection, counter bracing, physiotherapy, surgery etc are available but safety and efficacy of one treatment over another is under research. Ayurveda classifies this condition as Snayugata vata. According to Sushruta, Agnikarma (thermal cautery) is the one among the treatment modalities for Snayugata vata. Previously published randomised controlled trials have shown that therapeutic ultrasound is safe and effective for tennis elbow. However, the comparative efficacy of these two treatment modalities is unknown.

Objective

This study compares the effects of Agnikarma (AGK) with Therapeutic Ultrasound (TUS) in reducing pain, tenderness and restores the ability to do various tasks.

Materials and methods

A total of 30 patients were enrolled in the study as an open-label, double-armed, prospectively designed comparative clinical study, with 15 patients in each group. Group AGK received two sittings of Agnikarma and Group TUS received therapeutic ultrasound. To analyze the patients, three outcome measures were adopted: pain intensity, assessed with a Numerical Pain Rating Scale, tenderness – Grade 0 to Grade 4 (mentioned in Hutchinson's clinical methods) and pain and functional Disability assessed with the Patient Rated Tennis Elbow Evaluation (PRTEE) questionnaire. Assessment was done on 0^th, 8^th, 15^th, 30^th and 60^th day.

Result

Tennis elbow can be effectively treated with AGK and TUS. (p < 0.001 for pain, tenderness and PRTEE). While comparing between the groups, on 8^th day and 15^th day statistically significant difference in pain and PRTEE (p < 0.05) was noted between AGK and TUS groups. Agnikarma showed better results than therapeutic ultrasound in pain management and showed an improved quality of life from 8^th day onwards and for a period up to 2 months.

Conclusion

Both Agnikarma and therapeutic ultrasound have roles in the management of tennis elbow. However, starting on the 8^th day and continuing for up to 2 months, Agnikarma showed a significant benefit in pain management and improved status for quality of life.
