After more than a decade of war, the military medical complex has seen a significant decrease in high-energy combat casualties. Nonetheless, injuries to the tactical athlete persist in the form of more common low-energy Orthopaedics Sectionpedic injuries. Loss of muscle size and strength is experienced by many patients and high-level athletes after an injury. Reduction of protein synthesis and reduced myogenic stem cell content seem resistant to rehabilitation interventions. Personalized blood flow restriction (BFR) rehabilitation is a new technique that uses a specialized tourniquet system to reduce vascular flow in and out of an exercising limb to induce strength and hypertrophy responses at very low loads. BFR shows promising ability to activate muscle protein synthesis, and may be a powerful tool to mitigate the atrophic effects of anabolic resistance and increase up-regulation of myogenic stem cells. Ischemic preconditioning, applied to the extremities before or after strenuous exercise bouts, has demonstrated a protective effect on muscle tissue and a more rapid return of physical performance and strength measures. In this session, the speakers will review the basic science and evidence behind BFR and ischemic preconditioning, discuss their potential clinical application within military and civilian rehabilitation settings, and provide detailed case examples of the application of these treatment interventions.
Learning Objectives: Upon completion of this course, you will be able to:
1. Define the role and influence of anabolic resistance after musculoskeletal injury.
2. Discuss the challenges of current rehabilitation methods to reverse anabolic resistance.
3. Explain the scientific rationale behind blood flow restriction and ischemic preconditioning based on available clinical evidence.
4. Provide practical examples of the clinical application of blood flow restriction and ischemic preconditioning for patients undergoing both conservative management and postoperative rehabilitation and performance recovery.
