Spinal Cord Stimulation Assisted by Motor Rehabilitation Training for Restoring Motor Function After Spinal Cord Injury
- Conditions
- Spinal Cord Injuries
- Interventions
- Procedure: Spinal cord stimulation surgery (device) and motor rehabilitation
- Registration Number
- NCT05926843
- Lead Sponsor
- IRCCS San Raffaele
- Brief Summary
Interventional prospective longitudinal on the evaluation of spinal cord stimulation (SCS) assisted by motor rehabilitation training for restoring motor function in patients with spinal cord injury (SCI). The investigators will enroll ten research participants with clinically incomplete/complete SCI (patients with paraplegia or severe paraparesis) who will undergo SCS subsequently assisted by motor rehabilitation training for restoring motor function at IRCCS Ospedale San Raffaele, Milan, Italy. The main goal of the project is to evaluate the improvement in motor function generated by the combination of SCS and locomotor training. In line with recently published studies, the investigators propose that daily locomotor training in the presence of SCS with continuous stimulation parameters setting will enable the SCI individuals to stand and step independently while bearing full weight.

Group Intervention Description Individuals with functionally complete/incomplete spinal cord injury Spinal cord stimulation surgery (device) and motor rehabilitation Individuals with functionally complete/incomplete spinal cord injury (ASIA grade A, B or C) who will undergo SCS for chronic pain
- Primary Outcome Measures
Name Time Method Motor changes (MRC) Before surgery, then monthly up to 6-month from surgery The Medical Research Council's (MRC) scale of muscle power will be used to evaluate motor weakness. The MRC scale of muscle strength uses a score from Grade 5 (normal) to Grade 0 (no visible contraction) to assess the power of a particular muscle group in relation to the movement of a single joint.
Motor changes (LEFS)) Before surgery, then monthly up to 6-month from surgery The Lower Extremity Functional Scale (LEFS) will be used by clinicians as a measure of lower extremity function. It is a questionnaire containing 20 questions about a person's ability to perform everyday tasks (minimum score 0, maximum score 80).
- Secondary Outcome Measures
Name Time Method Chronic pain changes (MPQ) Before surgery and 6 months after procedure The McGill Pain Questionnaire (MPQ) can be used to evaluate a person experiencing significant pain. It consists of 15 descriptors (11 sensory; 4 affective) which are rated on an intensity scale as 0 = none, 1 = mild, 2 = moderate or 3 = severe.
Chronic pain changes (PCS) Before surgery and 6 months after procedure The Pain Catastrophizing Scale (PCS) assesses the extent of catastrophic thinking. It assesses the extent of catastrophic thinking due to low back pain according to 3 components: rumination, magnification, and helplessness. It is a 13-item scale, with a total range of 0 to 52. Higher scores are associated with higher amounts of pain catastrophizing.
Longitudinal brain and spine MRI reorganization Before surgery and 6 months after procedure Structural and functional brain and spine MRI analysis.
Spasticity changes Before surgery, then monthly up to 6-month from surgery The Modified Ashworth scale will be used to evaluate spasticity. This scale grades the muscle tone from 0 (normal) to 4 (severe spasticity).
Longitudinal neurophysiological reorganization (motor evoked potentials) Before surgery and 6 months after procedure Motor evoked potentials will be used to evaluate electrical signals recorded from the descending motor pathways or from muscles following stimulation of motor pathways within the brain.
Longitudinal neurophysiological reorganization (sensory evoked potentials) Before surgery and 6 months after procedure Sensory evoked potentials will be used to assess electrical activity in the brain in response to sensory stimulation.
Longitudinal neurophysiological reorganization (electromyography) Before surgery and 6 months after procedure Electromyography will be used to evaluate muscle response or electrical activity in response to a nerve's stimulation.
Chronic pain changes (ASC-12) Before surgery and 6 months after procedure 12-item Allodynia Symptom Checklist (ASC-12) evaluates presence of allodynia and hypoesthesia.
