Effectiveness of Low-Load Resistance Training With Blood Flow Restriction in Lateral Epicondylitis

Sponsor: Sisli Hamidiye Etfal Training and Research Hospital

Summary

Lateral epicondylitis, commonly known as tennis elbow, is a frequent musculoskeletal condition that causes pain, reduced grip strength, and functional limitations in daily activities. Exercise-based rehabilitation is a key component of treatment; however, the optimal exercise approach remains uncertain. Low-load resistance training combined with blood flow restriction (LLRT-BFR) has emerged as a promising method that may enhance training effects while using lower exercise loads, potentially reducing mechanical stress on the affected tissues while providing benefits comparable to high-load resistance training. The purpose of this study is to evaluate the clinical and ultrasonographic effects of LLRT-BFR in patients with lateral epicondylitis. Adults aged 18-65 years with a recent diagnosis of lateral epicondylitis who meet predefined inclusion and exclusion criteria will be enrolled and randomly assigned to one of two exercise-based treatment groups. Both groups will participate in the same supervised low-load resistance exercise program, while one group will perform the exercises with blood flow restriction and the other group will receive a sham application without meaningful blood flow restriction. Participants will undergo supervised exercise sessions twice weekly for six weeks. Outcomes will be assessed at baseline, on the first day after completion of treatment, and at 4 and 12 weeks during follow-up. The primary outcome will focus on functional status, while secondary outcomes will include pain intensity, pain sensitivity, grip strength, ultrasonographic measurements of tendon and muscle structure, and patient-reported treatment satisfaction. By comparing these two exercise approaches, this study aims to provide evidence regarding the effectiveness and safety of LLRT-BFR and to clarify its potential role in the rehabilitation of patients with lateral epicondylitis.
