About this trial

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.

Treatments tested in this trial

  • interventional group A

    Behavioral

    The interventional group will receive eccentric wrist extensor exercises combined with blood flow restriction therapy, using a pneumatic cuff inflated to 50-60% limb occlusion pressure. Exercises will be performed at 20-30% 1-RM using a 30-15-15-15 repetition protocol, emphasizing slow controlled eccentric contractions. Sessions will be conducted three times weekly for 8 weeks, totaling 24 supervised sessions.

  • control group b

    Behavioral

    The control group will undergo a heavy slow resistance training protocol, involving wrist extensor exercises performed at 70-85% of 1-RM, with slow concentric and eccentric phases (3 seconds each). Participants will complete 3-4 sets of 6-8 repetitions, with adequate rest intervals, following the same session frequency and duration as the intervention group.

Trial outcomes

Primary outcomes

1

Pain Intensity (Numeric Pain Rating Scale)

Pain intensity will be assessed using the Numeric Pain Rating Scale (NPRS), a validated 11-point scale ranging from 0 (no pain) to 10 (worst imaginable pain). Participants will rate their average elbow pain during daily activities involving the affected upper limb.

Time frame
Baseline, 4 weeks, and 8 weeks

Secondary outcomes

1

Patient-Specific Functional Performance (PSFS)

Functional performance will be assessed using the Patient-Specific Functional Scale (PSFS). Participants will identify activities affected by lateral epicondylitis and rate their ability to perform each activity on an 11-point scale ranging from 0 (unable to perform) to 10 (able to perform at pre-injury level). Higher scores indicate improved functional ability.

Time frame
Baseline, 4 weeks, and 8 weeks
