Condition: Neuropathic Pain · Chronic Pain · Sponsor: University Health Network, Toronto
Spinal cord stimulation (SCS) relies on stimulation of pain-relieving pathways in the spinal cord to treat chronic neuropathic pain. Traditional paresthesia-based SCS (PB-SCS) relies on providing analgesia through stimulation of spinal cord dorsal columns but it is often associated with attenuation of analgesic benefit and lack of acceptance of paresthesias. Recently introduced three different paresthesia-free (PF-SCS) modes of stimulation aim to overcome limitations of PB-SCS. Several questions regarding PB and PF SCS modes remain unanswered including the mechanisms of therapeutic benefit, criteria for selecting patients likely to benefit, and long-term outcomes. A concerted effort is required to understand and optimize utilization of SCS. This project has the twin goals of using neuroimaging techniques to understand mechanisms that underlies analgesic benefit from PB/PF-SCS modes and to identify criteria for selecting patients based on monitoring of pain and its related domains in patients undergoing SCS trials. Achieving these objectives will increase probability of analgesic benefit while minimizing adverse effects and knowledge gains from this study will be applicable to other therapies for chronic pain conditions.
