Go with the Flow? Considerations for Blood Flow Restriction Training in People with Neurologic Conditions.

Abstract

Blood flow restriction training (BFRT) with low intensity resistance or aerobic exercise can improve muscle strength and aerobic capacity, respectively. Furthermore, low intensity BFRT with resistance or aerobic exercise can be as effective as training at higher intensities without BFR in healthy adult populations. The clinical use of BFRT is therefore becoming increasingly common, particularly in otherwise healthy adults recovering from musculoskeletal injury or orthopedic surgery, for whom training at high intensities is not indicated. People with neurologic conditions may also benefit from training at lower intensities, as many individuals with neurologic conditions may not tolerate higher intensities for a variety of reasons, including advanced mobility restrictions, extreme weakness, severe fatigue, and/or pain. Indeed, more and more rehabilitation clinicians are beginning to use BFRT with their patients who have neurologic conditions even though there is very little evidence to support its safety, feasibility, or efficacy in those populations. In this perspective, we propose that BFRT can be an important alternative to conventional exercise training approaches for some individuals with neurologic conditions, and in the right circumstances can be delivered both safely and effectively. This perspective will also provide considerations and decision-making strategies that can help inform clinical decisions for rehabilitation practitioners considering the use of BFRT in their patients with neurologic conditions.
