Overview
Spinal cord stimulation (SCS) is an established treatment for chronic neuropathic pain, typically considered for patients who have not responded adequately to more conservative therapies. Despite its clinical use, the mechanisms underlying its therapeutic effects and the reasons for loss of efficacy over time remain poorly understood. This PhD project will investigate how different SCS paradigms influence pain processing and neuronal activity, building on our ongoing research using clinically relevant preclinical models of neuropathic pain and SCS in rats.
The project will combine behavioural, molecular and neurobiological approaches to investigate how different stimulation parameters and paradigms influence neural recruitment and the mechanisms underlying analgesia. A particular focus will be understanding why treatment efficacy may decline over time, including the role of axonal homeostasis during high-frequency stimulation. The project will also develop and validate long-term stimulation models, extending stimulation from minutes to days to better reflect clinical practice and investigate sustained neurobiological adaptations. This will provide important insights into the long‑term effects of SCS and strengthen the translational relevance of preclinical research. Ultimately, the findings will advance our understanding of how SCS works, why it sometimes fails, and how stimulation protocols can be optimised to improve the durability and efficacy of treatment for patients with chronic pain.
The supervisory team brings together complementary expertise in electrophysiology, pharmacology and experimental neuroscience across multiple species, supported by successful and well‑established research laboratories. The project will offer excellent multidisciplinary training and the opportunity to work in close collaboration with Saluda Medical, a global leader in spinal cord stimulation technology.
