Spinal Cord Stimulation for Lower Extremity Function

Status Not yet recruiting

Clinical Trial Summary

This prospective clinical study will investigate the ability of different spine imaging characteristics to predict ambulation recovery responsiveness using epidural spinal cord stimulator (SCS) in patients with chronic incomplete spinal cord injury (SCI). Epidural spinal cord stimulation below the level of injury can restore previously lost lower extremity voluntary motor function for some patients. The goal of this study is to establish whether spine imaging can be utilized as a biomarker to predict which patients will respond to spinal cord stimulation.

Clinical Trial Description

Ten patients with chronic spinal cord injury who are scheduled to receive a spinal cord stimulator for refractory chronic pain will be recruited throughout the Mass General Brigham health system. At baseline, participants will undergo a neurologic strength exam, Magnetic Resonance Imaging (MRI) of the spine and brain, electromyography (EMG) of the lower extremities, and will complete a battery of pain, motor function and quality of life questionnaires. Phase 1: The SCS Optimization phase consists of weekly research visits during the first month post-SCS implant. Settings of the spinal cord stimulator parameters will be modified for activation and optimal voluntary control of lower extremity muscles. Phase 2: The Individualized Neurorehabilitation phase consists of 4 weekly visits for a 5-month period. Participants will undergo neurorehabilitation with the stimulation settings turned on for motor control. Neurorehabilitation will be individualized and will progressively increase participants' physical activity, including assisted/independent standing, stepping and ambulation within safe limits. Participants will undergo monthly muscle strength and surface EMG testing. At the end of each research visit or neurorehabilitation session, SCS settings will be adjusted to the original pain management parameters. At the 6-month follow up participants will undergo a neurologic strength exam, MRI of the spine and brain, EMG of the lower extremities and a battery of questionnaires. After the last follow up visit, participants will have the opportunity to continue a long-term follow up or exit the study. SCS parameters will be adjusted to the pain management settings. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
