Effects of Blood Flow Restriction Training on Muscle Strength and Recovery in Adolescents After ACL Reconstruction Surgery

What this Trial Is About

Researchers are evaluating blood flow restriction training BFRT in adolescents aged 12 to 18 following anterior cruciate ligament reconstruction surgery ACLR. This study aims to understand how BFRT affects quadriceps muscle strength, overall function, and quality of life in these patients. The research focuses on determining the tolerability and benefits of BFRT compared to standard post-surgery rehabilitation. It addresses a critical need as adolescents have higher risks of reinjury and persistent muscle weakness despite current therapy approaches. Participants are randomly assigned to one of two groups a control group receiving standard physical therapy and a test group receiving the same physical therapy supplemented with BFRT. Both groups attend two physical therapy visits weekly for 16 weeks, with the test group performing exercises using the Delfi Personalized Tourniquet System to partially restrict blood flow during training. After 16 weeks, both groups continue standard rehabilitation until 24 weeks post-surgery. Physical therapists trained in the protocol oversee all sessions, which last about 60 minutes each. Throughout the study, participants complete strength tests, functional hop and balance assessments, and four patient-reported outcome questionnaires at multiple time points up to 24 weeks. Researchers also monitor discomfort and exertion during BFRT sessions. Data collection includes demographic, physiological, and radiographic information stored securely. The studys total duration for each participant is six months, allowing comprehensive evaluation of muscle strength recovery and quality of life after ACLR surgery with or without BFRT.
