简要总结
Ankle injuries, especially lateral ankle sprains, are prevalent in physically active individuals. Blood Flow Restriction Training (BFRT) has emerged as a promising method, employing partial arterial occlusion and full venous occlusion with low resistance to induce metabolic stress and achieve outcomes akin to heavy resistance training. This Randomized Controlled study explores the application of BFRT in addressing Chronic Ankle Instability (CAI), focusing on its efficacy in strength gains of extrinsic foot muscles, and potential benefits in functional performance.

Ankle injuries, especially lateral ankle sprains, are prevalent in physically active individuals. Blood Flow Restriction Training (BFRT) has emerged as a promising method, employing partial arterial occlusion and full venous occlusion with low resistance to induce metabolic stress and achieve outcomes akin to heavy resistance training.
This Randomized Controlled study explores the application of BFRT in addressing Chronic Ankle Instability (CAI), focusing on its efficacy in strength gains of extrinsic foot muscles, and potential benefits in functional performance.
At the Sharjah University Medical Campus, 45 athletes from Shabab Al Ahli Club, aged 18-40, participated in this randomized control study. The investigators randomly allocated the participants into three equal groups, with 15 individuals in each group. The investigators recruited the first group to an auto-regulated blood flow restriction training plus traditional treatment program (ARBFRT+TT), the second group to a non-regulated blood flow restriction training plus traditional treatment program (NRBFRT+TT), and the third group to a traditional treatment program only without BFRT (TT group). The investigators assessed extrinsic foot muscle strength using an isokinetic device and functional performance using Functional Ankle Disability Index (FADI) and Rate of perceived exertion scale (RPES), both pre- and post 6-week treatment.

结局指标
主要结局
Muscle Strength
时间窗: 6 weeks
An isokinetic dynamometer (Physiomed Elektromedizin AG \[TP Module, CON-TREX MJ\], Schnaittach, Germany) was used for strength testing. Using the previously identified ankle evertors/invertors and plantarflexors/dorsiflexors muscles, the investigators assessed the average peak torque to body weight ratio (concentric/concentric) at an angular velocity of 60°/s. Calibration of the dynamometer was performed prior to evaluation. Submaximal three and maximal three exercise sessions were given to participants to acclimate them to the testing methodology. Each subject rested for two minutes before cycling through the active range of motion three times in a row at maximum concentric contraction. To provide sufficient recovery between contractions, a 5-minute rest interval was included in each test condition. It was expected that participants would give it their all when taking the exam. For every test, the appropriate ankle isokinetic device was used for strength testing.
