Cervical Myelopathy

Spinal cord associative plasticity (SCAP) is a combined cortical and spinal electrical stimulation technique developed to induce recovery of arm and hand function in spinal cord injury. The proposed study will advance understanding of SCAP, which is critical to its effective translation to human therapy. The purpose of the study is to: 1. Determine whether signaling through the spinal cord to the muscles can be strengthened by electrical stimulation. 2. Improve our understanding of the spinal cord and how it produces movement. 3. Determine whether spinal surgery to relieve pressure on the spinal cord can improve its function. Aim 1 is designed to advance mechanistic understanding of spinal cord associative plasticity (SCAP). Aim 2 will determine whether SCAP increases spinal cord excitability after the period of repetitive pairing. In rats, SCAP augments muscle activation for hours after just 5 minutes of paired stimuli. Whereas Aims 1 and 2 focused on the effects of paired stimulation in the context of uninjured spinal cord, Aim 3 assesses whether paired stimulation can be effective across injured cord segments. Aim 3 will incorporate the experiments from Aim 1 and 2 but in people with SCI, either traumatic or pre-operative patients with myelopathy in non-invasive experiments, or targeting myelopathic segments in intraoperative segments.

The goal of this clinical trial is to learn whether starting rehabilitation earlier after surgery can improve recovery and is feasible and acceptable for adults with degenerative cervical myelopathy (DCM) undergoing cervical spine surgery. The main question it aims to answer is: Does starting rehabilitation earlier improve walking, balance, physical activity, quality of life, and nervous system function after surgery? Researchers will compare participants who begin rehabilitation two weeks after surgery with participants who begin rehabilitation six weeks after surgery to see if earlier rehabilitation leads to better recovery outcomes and participation. Participants will: Be randomly assigned to begin rehabilitation either two weeks or six weeks after surgery. Attend physical therapy sessions twice per week for eight weeks focused on strength, balance, and walking. Complete assessments of walking ability, balance, physical activity, quality of life, and nervous system function over several months after surgery. Provide feedback about their experience with the rehabilitation program, including satisfaction and any side effects or challenges related to participation.

Proprioceptive deficits in degenerative cervical myelopathy (DCM) is a progressive neurological deficits in somatosensory and motor function which affects the body balance and motor control. DCM usually presents with body incoordination, hand clumsiness and gait disturbance associated with proprioceptive dysfunction that hinders the physical performance and functions. In this study, a non-invasive assessment protocol on proprioception will be developed for detecting subtle proprioceptive deficits at the early stage of disease through simple Physical Performance Tests for population older than 45. By adopting the physical performance tests as the diagnostic predictors of DCM, we aim to avoid the development of devastating consequences and disabilities.

Recent evidence has demonstrated a high rate of undiagnosed cervical myelopathy in patients presenting with hip fractures from a ground level fall. Identification and treatment of cervical myelopathy can help prevent falls and future fragility fractures. The purpose of this study is to screen ground level fall hip fracture patients for cervical myelopathy using a history, physical exam, and then offer an MRI if indicated.

The goal of this observational study is to determine if patients with cervical myelopathy who participate in a Tai Chi program will demonstrate improved gait and balance compared to patients who undergo usual care. Participants must be 18 years or older and have a diagnosis of cervical myelopathy.

To create a research repository of patients with known degenerative cervical myelopathy (DCM) and a control cohort of subjects who have non-myelopathic spinal disease. This repository will be used to assess functional and/or biological measures that may allow for improved prediction of symptomatic progression and response to treatment in patients with DCM. In addition, this repository will be used to develop a risk assessment scale to accurately predict functional outcomes following operative management of DCM.

The proposed study seeks to understand how the cervical spinal cord should be stimulated after injury through short-term physiology experiments that will inform a preclinical efficacy trial. The purpose of this study is to determine which cervical levels epidural electrical stimulation (EES) should target to recruit arm and hand muscles effectively and selectively in spinal cord injury (SCI).

The study will be a non-randomized, non-blinded pilot study to analyze the safety and feasibility of a non-significant risk device, transcutaneous spinal cord stimulation. The aim is to include 30 total patients, 10 patients in each of 3 groups: 1. Non-traumatic spinal cord injury (ntSCI) with diagnosis of degenerative cervical myelopathy and offered surgical intervention. 2. Early tSCI screened during the hospital admission when cervical/thoracic spinal injury was diagnosed. 3. Delayed tSCI (control) screened 6-24 months after acute cervical/thoracic spinal injury.

The aim of this low interventional study is to detect microstructural degeneration prior to the presentation, worsening, or persistence following surgical or conservative treatment of cervical degenerative myelopathy signs and symptoms using quantitative imaging metrics and functional biometric analysis. The endpoints of the study are to collect and compare the clinical, biometric, neurophysiological and imaging data. The objectives of the study are: * to implement and validate a novel quantitative Magnetic Resonance (qMRI) protocol clinically for the identification and quantification of microstructural spinal cord damage * to compare qMRI data to clinical and neuromotor's and corresponding neurophysiological data * to create an integrated diagnostic tool for early diagnosis and disease monitoring of myelopathy, and for identification of a more reproducible and quantitative scale for assessing reversible and irreversible spinal cord damage combining clinical, biometric, imaging and neurophysiological data in patients suitable for surgical or non-surgical treatment. Patient will undergo: * MRI (baseline - 1 month- 6 months) * clinical data collection (baseline- 1 month - 6 months) * neuromotor assessment (baseline - 1 month - 6 months) * neurophysiological assessment (baseline - 6 months) * surgery if applicable Quantitative MRI of the spinal cord could provide a new objective system for identification of patients who require surgery before developing irreversible clinical damage, and to avoid surgical treatment in those who do not require it. Additionally, quantitative MRI, in combination with clinical data such as, neuromotor tests, could provide an important approach to assess the effectiveness of the therapeutical approach.
