Comparison of the efficiency of peloidotherapy and extracorporeal shock wave therapies in patients diagnosed with lateral epicondylitis: a prospective, randomized, controlled study.

Abstract

Various treatment methods are used in the management of lateral epicondylitis (LE); however, there is no universally accepted standard treatment approach. The aim of this study is to compare the effects of peloidotherapy and extracorporeal shock wave therapy (ESWT) on pain, functional status, and quality of life in the treatment of LE. The study was designed as a hospital-based, prospective randomized controlled trial. Ninety patients, with a mean age of 47.30±7.95 (range, 18 to 65 years), diagnosed with chronic (3 months) unilateral LE were included in the study. The patients were randomly divided into two groups. The peloidotherapy group received 15 sessions of peloid therapy for 3 weeks, 5 days a week, while the ESWT group received three sessions of ESWT (1.8 bar, 10.0 Hz, 2000 impulses) for 3 weeks, once a week. The patients were evaluated before treatment, at the end of the treatment, and one month after the treatment. The groups were compared in terms of pain, quality of life, functional status, and handgrip strength. At the end of the treatment and one-month follow-up, statistically significant improvements were observed in all parameters. This study is the first randomized trial comparing peloidotherapy to ESWT as an adjunct to exercise therapy in LE. Both ESWT and peloidotherapy, when added to exercise therapy, showed positive short-term effects on pain, quality of life, functional status, and handgrip strength in primary conservative treatment of chronic LE (p<0.001), and no superiority was found between them in terms of efficacy. Peloidotherapy or ESWT may be preferred in the treatment of lateral epicondylitis, depending on the patient's condition. Peloidotherapy appears to be more advantageous due to its lower side effects and painless nature. ClinicalTrials.gov ID: NCT04748406.
