简要总结
This study compared three different treatment approaches for lateral epicondylitis (tennis elbow), a common condition that causes pain on the outside of the elbow.Twenty-seven patients diagnosed with lateral epicondylitis were randomly assigned to one of three treatment groups for 6 weeks:Group 1 - Blood Flow Restriction Exercise (BFRE): Patients performed wrist strengthening exercises using light weights (30% of their maximum capacity) while wearing a pressure cuff on the upper arm that partially restricted blood flow. Sessions were held twice per week under supervision, along with daily stretching exercises and a wrist orthosis.Group 2 - Eccentric Exercise: Patients performed slow lowering (eccentric) wrist exercises using heavier weights (70% of their maximum capacity) five times per week under supervision, along with daily stretching exercises and a wrist orthosis.Group 3 - Orthosis Only: Patients wore a wrist orthosis that held the wrist in a slightly extended position throughout the day and performed daily stretching exercises at home.The main goal was to determine whether blood flow restriction exercise could reduce pain and improve hand function more effectively than eccentric exercise or orthosis use alone. Pain levels, hand grip strength, finger pinch strength, and upper limb function were measured before and after the 6-week treatment period.The study was conducted at Dokuz Eylül University, Department of Orthopedics and Traumatology, İzmir, Turkey.
详细描述
Lateral epicondylitis (tennis elbow) is a musculoskeletal disorder affecting approximately 1-3% of the general population. It is characterized by pain and tenderness at the lateral epicondyle of the elbow due to degenerative changes in the extensor carpi radialis brevis (ECRB) tendon caused by repetitive microtrauma. Conservative treatment options include rest, orthotic devices, physical therapy, and exercise programs.
Eccentric exercise has been widely recommended as a first-line conservative treatment for lateral epicondylitis. However, these programs typically require loading at 70% or more of one-repetition maximum (1-RM), which may not be tolerated by patients experiencing significant pain.
Blood flow restriction exercise (BFRE) is a training method in which a pneumatic cuff is applied to the proximal portion of a limb to partially restrict arterial blood flow and completely restrict venous return during low-load resistance exercise. BFRE has been shown to produce muscle strength and hypertrophy gains at loads as low as 20-40% of 1-RM, making it a potential alternative for patients who cannot tolerate heavy loading. Recent studies have demonstrated the effectiveness of BFRE in various musculoskeletal conditions including osteoarthritis, anterior cruciate ligament reconstruction, and patellar tendinopathy. However, evidence for its use in lateral epicondylitis is limited.
STUDY DESIGN:
This was a prospective, randomized controlled trial with three parallel groups. Patients were allocated using block randomization with blocks of nine.
