Evaluating Low-Load Blood Flow Restriction Exercise for Pain Relief in Military Personnel with Lower Limb Injuries During Rehabilitation

What this Trial Is About

Pain following musculoskeletal injury can limit recovery and reduce the number of military personnel fit for operations. This research aims to evaluate low load blood flow restriction BFR exercise as a method to reduce pain and improve rehabilitation outcomes in UK military patients with lower limb injuries. The study seeks to find the most effective BFR exercise protocol and understand the physiological reasons behind any pain relief it may provide. Participants will receive one of two BFR exercise protocols using a pneumatic tourniquet system placed on the thigh during lower limb strengthening exercises such as leg press and knee extensor exercises. One group will have the cuff inflated to 80% of limb occlusion pressure, and the other to 40%. Both protocols involve four sets of specific repetitions at 20% of one repetition maximum. These interventions are combined with standard residential rehabilitation including group and individual exercise therapy, education sessions, and one-on-one support from various healthcare professionals. During the study, participants will be assessed using various pain and function measurements before, during, and after the intervention, including the Brief Pain Inventory and Pressure Pain Threshold Testing. Other evaluations include strength tests, disability scores, wellbeing questionnaires, and pain ratings tracked daily. This detailed monitoring will help researchers measure pain changes, physical improvements, and the safety of BFR exercise. Participation lasts through the intervention and follow-up assessments over several days.
