About this trial
The goal of this randomized controlled clinical trial is to investigate the effects of blood flow restriction training on the parameters surrounding tennis elbow afflicted patients including pain, disability, and grip strength.
The main question this study aims to answer is:
1- Does blood flow restriction training offer significantly better effects on pain, disability, and grip strength when compared to conventional strength training without blood flow restriction in patients afflicted with tennis elbow? Research will compare two groups with tennis elbow where both will perform the same rehabilitation program consisting of conventional physical therapy for tennis elbow as well as a strength training program with the only difference being that one group will undergo blood flow restriction training while the other will not.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Patients that were included in this study were diagnosed with lateral epicondylitis by a medical doctor for less than 3 months.
Dominant hand was diagnosed with lateral epicondylitis.
They were aged between 20 and 40 years old.
With decreased grip strength and wrist range of motion.
Disqualifiers
Patients with chronic diabetes.
Any type of trauma or fracture in the upper extremities in the last 3 months.
Patients with any vestibular problems.
Patients with deep vein thrombosis (DVT).

Factorial
Treatments tested in this trial
Blood Flow Restriction Training
Other interventionThe affected limb will have a cuff placed proximally and inflated to occlude the blood flow by 40% attested using a golden standard vascular doppler after which the individuals will perform the strengthening program set forth by the physical therapist. This is preceded by other tennis elbow interventions such as ultrasound, stretching, and deep friction massage at the extensor origin.
Conventional Strength Training
Other interventionThe individuals in this group will undergo the same conventional physical therapy program as the other group including ultrasound, stretching, and deep friction massage. In addition, they will undergo the same strengthening program set forth by the physical therapist however with no blood flow restriction of any kind.
Treatment groups
25 Participants

Trial outcomes
Primary outcomes
1
Hand Grip Strength
The hand grip strength was tested using a Camry Dynamometer, which is a smedly spring type dynamomter, whose reliability and validity in measuring handgrip strength has been reported by available literature.
Time frame
Taken initially before intervention process and after the conclusion of the intervention period (6 weeks, 12 sessions).Secondary outcomes
1
Patient Related Tennis Elbow Evaluation Scale (PRTEES)
A scale specifically developed for Lateral Epicondylitis and it was used to determine forearm pain and disability, this scale consists of two parts, namely pain (5 items) and functional activities (10 items), each item has a score from 0 (no pain at all when performing a task) to 10 (the worst pain or unable to perform the task). The total score is the combined score of the 2 parts (OZMEN, KOPARAL, KARATAS... et al 2021), and it is proven that it is a reliable and valid tool for measuring pain and disability in LE patients (Jafarian, Barati, Sadeghi-Demneh 2021)
Time frame
Taken initially before intervention process and after the conclusion of the intervention period (6 weeks, 12 sessions).2
Numerical Pain Rating Scale (NPRS)
A widely used 11-point scale (0-no pain, 10- sever pain) which has been proven to have good test reliability in individuals with chronic pain (Cheatham, Stull, Kobler 2018)
Time frame
Taken initially before intervention process and after the conclusion of the intervention period (6 weeks, 12 sessions).Sponsors and contacts
