Project Tendura: The Impact of Blood Flow Restriction Resistance Training (BFR-RT) in Patients With Achilles Tendon Rupture (ATR) Repair

The goal of this clinical trial is to determine whether blood flow restriction resistance training (BFR-RT) improves postoperative muscle recovery and functional outcomes following primary surgical repair of acute Achilles tendon rupture (ATR) in adults undergoing standard rehabilitation. The main questions it aims to answer are: Does patient-specific BFR-RT improve ankle plantarflexion strength recovery compared with sham BFR-RT or standard rehabilitation alone? Does BFR-RT improve gastrocnemius-soleus muscle morphology and patient-reported functional outcomes following ATR repair? Researchers will compare (1) BFR-RT combined with standard physical therapy, (2) sham BFR-RT combined with standard physical therapy, and (3) standard physical therapy alone to determine whether BFR-RT enhances muscle recovery, functional outcomes, and return-to-activity timelines following surgical ATR repair. Participants will: Be randomized to BFR-RT + standard physical therapy, sham BFR-RT + standard physical therapy, or standard physical therapy alone Perform supervised rehabilitation exercises using a personalized tourniquet system calibrated to limb occlusion pressure (LOP) depending on group allocation Undergo isometric ankle plantarflexion strength testing using the Fysiometer platform Receive ultrasound imaging of the gastrocnemius-soleus complex to assess muscle cross-sectional area Complete patient-reported outcome measures assessing pain and physical function Attend follow-up evaluations at 6 weeks, 3 months, 4.5 months, 6 months, and 12 months postoperatively

Evaluating the Efficacy of Blood Flow Restriction Therapy in a Randomized Clinical Trial for Postoperative Rehabilitation Following Ankle Ligament Reconstruction

The goal of this single blinded clinical trial is to investigate blood flow restriction (BFR) for rehabilitation of patients after ankle ligament reconstruction surgery. Outcome measures will be compared between the standard of care (SoC) and BFR groups at the end of the study intervention. Following standard surgical procedures, both groups will undergo physical therapy by a certified physical therapist for a minimum of 6 weeks. The SOC group will receive standard physical therapy without use of BFR. The BFR group will receive physical therapy with BFR. Outcome measures of interest will be taken at the start of physical therapy (time 0) and at the end of physical therapy (minimum of 6 weeks of PT) for both groups. Outcome measures of interest include: * muscle atrophy; * ankle function; * fatigability/manual muscle testing; * pain scores; * cardiovascular effects (heart rate, blood pressure).

Optimizing Rehabilitation After Achilles Tendon Rupture Repair: The Role of Blood Flow Restriction Training in Tendon and Muscle Recovery

The goal of this clinical trial is to investigate whether rehabilitation with blood flow restriction (BFR) offers added value compared to conventional rehabilitation in patients undergoing surgical repair for Achilles tendon rupture. The study will include adult patients of all sexes who have undergone surgical treatment at two selected hospitals. The main questions it aims to answer are: Does BFR-enhanced rehabilitation improve functional recovery compared to conventional rehabilitation? What are the effects of BFR on muscle strength and tendon recovery? Researchers will compare blood flow restriction (BFR) therapy with conventional rehabilitation to determine whether BFR leads to improved clinical, muscular, and tendon-related outcomes. Participants will: 1. Undergo standard surgical repair of the Achilles tendon 2. Be randomly assigned to a 24-week exercise therapy program-either with or without blood flow restriction (BFR)-starting four weeks post-surgery 3. Take part in follow-up assessments at weeks 4, 8, 12, 18, 24, and 52, which will include: * Questionnaires on pain, quality of life, fear of movement, and return to sport * Medical imaging techniques such as ultrasound, MRI, shear wave elastography, and power Doppler * Muscle strength testing * Blood sample collection, along with a tendon tissue sample taken during surgery

Blood Flow Restriction Training For The Treatment Of Lateral Epicondylopathy

The study aims to evaluate the effectiveness of Blood Flow Restriction Training for the treatment of lateral elbow epicondylopathy.

Blood Flow Restriction Following ACLR w/Quad Autograft

This project is intended to acquire objective measurements of implementing BFR rehabilitation in ACL reconstructions to show any changes upon completion of the BFR protocol. The results in this study will hopefully represent valuable data in the support of using autografts for ACL reconstructions in high level athletes wanting a full recovery and return to high level of sport. It has been speculated that use of autografts in ACL reconstructions leads to more quad weakness and muscle atrophy due to tendon harvesting. (Slone et al., 2015) More recently, BFR has shown promise in expediting the recovery and rehabilitation process post-surgically. By implementing BFR following ACL reconstructions with autografts, we hope to mitigate the major deterrent for autograft use and giving patients a more cost-effective approach to surgery.

The Enhancement Effect of Low-Level Laser Therapy for Muscle Training with Combined NMES and BFR

Blood flow restriction training (BFR) with neuromuscular stimulation (NMES) is employed for individuals with limited mobility and joint issues. However, this approach is highly susceptible to muscle fatigue, despite its potential beneficial effects on muscle strength. Recently, there has been growing interest in using low-level laser therapy (LLLT) to address muscle fatigue. LLLT, known for improving microcirculation and mitochondrial function, shows promise in alleviating enhanced muscle fatigue associated with combined BFR and NMES training. Despite these positive effects, there is limited knowledge about the short-term training impact of combined BFR and NMES with LLLT preconditioning. This project aims to investigate whether the photobiomodulation effects of LLLT could further enhance the training benefits of combined BFR and NMES. The study will employ an integrated analysis of decomposition surface EMG, EEG, and mechanomyogram to explore the behavior and neuromuscular mechanisms underlying the training benefits. If additional benefits are identified, LLLT pre-conditioning is recommended to enhance the use of combined BFR and NMES.
