Summary

This study aims to expand the knowledge and capacity for neuromodulation to improve the debilitating effects of severe spasticity (spasms, tonic muscle activity and/or clonus) in persons with spinal cord injury (SCI). The purpose of this study is to compare if spinal cord epidural stimulation can treat severe spasticity more effectively and have fewer side effects than a baclofen pump.

Detailed description

This study aims to expand our knowledge and capacity for neuromodulation to improve the debilitating effects of severe spasticity (spasms, tonic muscle activity and/or clonus) in persons with spinal cord injury (SCI) who are not adequately treated with oral pharmacological management, while avoiding side effects, and also improving voluntary control using surgically implantable targeted tonic spinal cord epidural stimulation (scES) . Individuals recruited and enrolled in the study will have significant spasticity not adequately treated by oral medications and clinically referred for an intrathecal baclofen pump trial. Current treatment of severe spasticity by pharmacological treatments are associated with several concomitant side effects that have consequences including limiting the ability to participate in and respond to neurorehabilitation15 and diminishing quality of life. Also, for persons with SCI and severe spasticity, available rehabilitation therapies are limited in their ability to foster appropriate neural excitation and subsequently motor recovery. This study focuses on ameliorating severe spasticity through specific spasticity-targeted spinal cord epidural stimulation (SP-scES) that has been shown to mediate levels of neural excitation for movement and unwanted muscle activation. The study will be evaluated as compared to a standard of care control group using pharmacological administration via an intrathecal baclofen pump (ITBP). In the long-term, this study will also provide a framework to develop clinically viable approaches with tools to provide optimized care for individuals with chronic SCI. This research is directly aimed to improve the quality of life for those affected by and living with SCI by reducing spasticity (and increasing voluntary control of movement) in the home and community while avoiding debilitating side effects of long-term pharmacological intervention.

Type	Name	Description
DEVICE	Epidural implant stimulation device	Individuals randomized to the Baclofen pump device group will continue with their clinical surgical and maintenance plan while also participating in all of the outcomes (assessments). The epidural implant group will undergo the research protocol for epidural stimulator surgical implant followed by mapping studies to identify targeted stimulation configurations for spasticity.
