简要总结
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.
详细描述
Lateral epicondylitis, commonly known as Tennis elbow, is a musculoskeletal condition characterized by pain at the lateral epicondyle due to repetitive forearm and hand movements. While it often improves over time, some cases may worsen. Diagnosis involves physical signs, including pain, decreased grip strength, tenderness, and pain during wrist flexion. Medical imaging such as MRI and clinical tests like Mills and Cozen's are used for confirmation.
According to Lenoir, Mares, Carlier (2019), physical therapy is the primary treatment, with exercises like eccentric muscle strengthening, deep friction massage, stretching, ultrasound, and laser therapy proving beneficial. Blood flow restriction training (BFR) has gained interest for enhancing strength and muscle mass. BFR involves partially restricting blood flow using a strap or cuff, inducing muscle hypoxia. Despite the unclear mechanism, BFR has shown positive effects on muscle tissue, possibly related to hypoxia and muscular acidosis.
The lack of studies on BFR's impact, especially on smaller muscle groups like fingers and wrists, creates a need for investigation. Given the commonality and impact of lateral epicondylitis symptoms, this study aims to compare the effectiveness between BFR training with standard PT exercises and standard PT alone in patients with lateral epicondylitis. Thus the purpose of this study is to prove that BFR training is more effective than standard physical training in improving the parameters surrounding tennis elbow.
The participants will be randomized into 2 groups. The standard physical therapy (group1) training consists of :1-ultrasound therapy, 2-laser, 3-deep friction massage followed by ice on the proximal attachment of the extensor tendon, 4-heat, 5-stretching of the wrist flexors and extensors, 6-strengthing of the wrist extensors combined with BFR.
(Group 2) will be treated with the same interventions excluding BFR training. Participants in both groups will be receiving treatment 2 times per week for 12 sessions.

研究组 & 干预措施
Blood Flow Restriction Training Group
The experimental group will undergo conventional physical therapy including ultrasound, stretching, icing, heat, and deep friction massage applied at the extensor origin. In addition, the experimental group will undergo blood flow restriction strength training including the following: the weight of the dumbbell should be between 20-40% of their 1 rep max. The exercises were targeting the extensor muscles, applied by extending the wrist while holding the dumbbel and exercises targeting the supinator's and pronators while the participants were holding the dumbbell with forearm in neutral position, and were asked to supinate or pronate their forearm.
The cuff will be placed proximally at the affected arm and inflated to achieve 40% limb occlusion depending on size attested using a a golden standard vascular dopler and all blood flow restriction activities were done with a licensed and experienced physical therapist.
干预措施: Blood Flow Restriction Training (Other)
Conventional Strength Training Group
The active comparator group will undergo the same interventions as the experimental group with the addition of conventional strength training including the same program as the experimental group but without blood flow restriction of any kind: the weight of the dumbbell should be between 20-40% of their 1 rep max. The exercises were targeting the extensor muscles, applied by extending the wrist while holding the dumbbell for 4 sets (35 repetitions, 15 repetitions,15 repetitions,15 repetitions) respectively, and exercises targeting the supinator's and pronators while the participants were holding the dumbbell with forearm in neutral position, and were asked to supinate or pronate their forearm.
