Interventions

  • BFR 80 — DEVICE
    The intervention involves placing a pneumatic tourniquet system over the proximal thigh. The cuff is inflated to 80% of limb occlusion pressure during lower limb strengthening exercises. These exercises include leg press and knee extensor exercises. Four sets (30,15,15,15 repetitions) performed at 20% of one repetition maximum.

Study Details

Pain can be one of the primary limiting factors to progress following musculoskeletal injury and may be caused by trauma or degenerative changes. There are few exercise rehabilitation interventions able to relieve pain, thereby reducing the number of military personnel fit for operations. Low load blood flow restriction (BFR) exercise has been shown to elicit an analgesic response and promote beneficial physiological changes in a variety of clinical populations. This two phase study, aims to: * Determine the most effective and feasible BFR resistance exercise protocol for reducing pain in UK military patients. * Determine the efficacy of an optimal BFR exercise protocol for reducing pain and improving rehabilitation outcomes in UK military patients. * Identify key physiological mechanisms underpinning any beneficial effect of BFR exercise on pain. Consequently, results from this study will have direct clinical application and will aid best practice guidelines for the management of pain across Defence Rehabilitation by influencing the future rehabilitation paradigm. The investigators believe the results and impact will be far reaching, providing invaluable insight and knowledge to the clinical and scientific community to not only those embedded within Defence Rehabilitation, but also those working in civilian sector organisations and professional sport also.

Arms

  • Experimental: BFR80
    Low load blood flow restriction training with high-pressure cuff (80% AOP) in addition to standard residential rehabilitation consisting of; (1) exercise-based therapy delivered in group settings and individually to address a variety of physical components relating to their pathology (e.g., balance and co-ordination, cardiovascular endurance, mobility and flexibility, motor control and dynamic stability, and muscular strength), (2) patient education sessions (e.g., activity modification, behavioural change, and focusing on pain management), and (3) one-on-one support sessions (e.g., dietetics, occupational therapy, physiotherapy, podiatry, prosthesis/orthosis specialists, social workers, and speech and language therapists).
  • Active Comparator: BFR40
    Low load blood flow restriction training with low-pressure cuff (40% AOP) in addition to standard residential rehabilitation consisting of; (1) exercise-based therapy delivered in group settings and individually to address a variety of physical components relating to their pathology (e.g., balance and co-ordination, cardiovascular endurance, mobility and flexibility, motor control and dynamic stability, and muscular strength), (2) patient education sessions (e.g., activity modification, behavioural change, and focusing on pain management), and (3) one-on-one support sessions (e.g., dietetics, occupational therapy, physiotherapy, podiatry, prosthesis/orthosis specialists, social workers, and speech and language therapists).
