Effectiveness of Eccentric Training With Blood Flow Restriction Therapy Versus Resistance Training in Patients With Lateral Epicondylitis
This randomized controlled trial aims to compare the effectiveness of eccentric training combined with blood flow restriction (ECC+BFR) versus heavy slow resistance (HSR) training in patients with chronic lateral epicondylitis. The study will recruit 40 participants (accounting for 10% attrition), aged 25-45 years, from Sakina Memorial Hospital Sheikhupura and University of Lahore Teaching Hospital using convenience sampling. Participants will be randomly allocated into two groups: an interventional group receiving ECC+BFR and a control group undergoing HSR training. Both interventions will be administered three times per week for 8 weeks under professional supervision. Outcome measures including pain intensity (NPRS), patient-specific functional performance (PSFS), muscle strength, and hypertrophy will be assessed at baseline, 4 weeks, and 8 weeks. Data will be analyzed using SPSS, with appropriate parametric or non-parametric tests applied after checking data normality. Ethical approval will be obtained, informed consent will be secured, and participant confidentiality will be strictly maintained.
• Patient aged between 25 and 45 years. Both male and female participants with unilateral symptoms only. Clinically diagnosed unilateral lateral epicondylitis (LE), confirmed by positive Cozen's and Mills' tests. Symptom duration exceeding 12 months, indicating chronic LE.
