The impact of blood flow restriction training on lateral epicondylitis grip strength and disability

Abstract

Background: Tennis elbow, also known as lateral epicondylitis, is a common ailment marked by pain and diminished grip strength. Because traditional rehabilitation techniques can produce variable outcomes, other treatments such as Blood Flow Restriction (BFR) training are being investigated. BFR aims to improve muscle strength and function by limiting blood flow during low-load activities.Objective: This case study assesses the impact of BFR training in improving grip strength and reducing disability in a patient with lateral epicondylitis.Methods: Low-load resistance exercises that targeted the forearm muscles were part of a 6-week BFR training program for a patient with lateral epicondylitis. A dynamometer was used to test grip strength, and the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire was used to assess disability both before and after the intervention.Results: Significant functional improvement and pain reduction were demonstrated by the patient, who demonstrated a 25% gain in grip strength and a 40% decrease in impairment based on DASH ratings.Conclusion: In order to improve grip strength and lessen handicap in lateral epicondylitis, BFR training might be a useful supplement to traditional therapy. To validate these findings in broader populations, more research is required.
