About the Project

Pain is among the primary limiting factors to progress in individuals experiencing musculoskeletal injury and may be caused by trauma or degenerative factors. In both scenarios a period of off-loading is often required. This increase in physical inactivity or immobilisation can result in rapid disuse atrophy which can weaken the muscle tissue and surrounding connective tissues. Greater complexity of an injury can significantly increase the duration of rehabilitation, and if pain isn’t managed effectively it can manifest into chronic pain. In both scenarios the individual is likely to be medically downgraded and unable to fulfil their primary job role, reducing operational readiness and at significant cost to the Ministry of Defence (MOD). Few rehabilitation strategies are available to mitigate the pain responses following complex musculoskeletal injuries in military personnel, which consequently often leads to pharmaceutical based intervention with opioids being a commonly used intervention. Clinicians seek therapeutic interventions that may help alleviate symptoms of pain thereby facilitating greater engagement in exercise-based rehabilitation to promote muscle hypertrophy, strength, and physical function. It is these clinical challenges that justify ‘rehabilitation following musculoskeletal injury’ being among the top research priorities for Defence Medical Services (DMS).

Over the previous 5 years, blood flow restriction (BFR) resistance exercise has become a cornerstone of rehabilitation practices worldwide. Applying BFR during low intensity resistance (i.e. 20-30% of maximum strength) and aerobic (i.e. <50% VO2max) exercise can elicit improvements in muscle strength and hypertrophy in individuals unable to tolerate heavy load resistance training (i.e. 70% of maximum strength). Importantly, there is now a growing body of evidence that supports the use of BFR exercise as an acute and chronic pain modulator in individuals with musculoskeletal injury.

The overall aim of this PhD is to investigate the effectiveness of using different modes of BFR application to treat pain and complex musculoskeletal injuries in military personnel, and explore the associated mechanisms, optimisation of this intervention and the impact and possible integration of this technique into the unique rehabilitation paradigm of DMS.
