Filter by: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.
This study in order to best tidal volume mechanical ventilation in patients with cervical spinal cord injury (sci) as the research point, through higher low volume Settings to find the difference of two groups of patients to prevent the incidence of hypoxemia, to find suitable Settings, tidal volume in patients with lower mechanical ventilation in patients with cervical spinal cord injury (sci) the incidence of pulmonary complications, live less intensive care unit (ICU).
The purpose of this research project is to investigate the incidence of impaired swallowing (dysphagia) after anterior cervical spine surgery (ACSS) and to study the long-term effect of dysphagia on nutritional status 12 ± 3 months later. Furthermore, to investigate the effect of a new rehabilitation method for dysphagia among individuals with swallowing dysfunction after ACSS.
The aim of this study is to determine the effects of rehabilitation on dexterous hand movements and cortical motor map changes in tetraplegic patients following nerve transfer surgery. The working hypothesis is that robot-assisted, intensive rehabilitation will support the return of hand and arm function and strengthen the cortical representations of targeted muscles. The investigators will assess this through TMS mapping and clinical measures of hand and arm function.
Compromised respiratory function as a result of tetraplegia is a leading cause of rehospitalisation for the tetraplegic patient group. Electrical stimulation of the abdominal muscles has previously been used to improve the respiratory function of tetraplegic patients in the chronic stage of injury. In this study the investigators aim to evaluate the optimum protocol for the use of electrical stimulation of the abdominal muscles to improve the respiratory function of the tetraplegic population. The investigators also aim to investigate whether abdominal functional electrical stimulation combined with mechanical insufflation-exsufflation can be used to help further improve the respiratory function of the tetraplegic population.
The cervical spine is most commonly injured, accounting for 53.4% of spinal injuries. More than 40% of all spinal injuries occur at either C4, C5 or C6 levels leading to variable loss of function in the upper extremities. Traditionally, patients sustaining a cervical spine injury were followed for 2 years to ensure that recovery had stabilized before offering upper extremity reconstruction. This type of reconstruction includes active muscle transfer, tendon transfer and joint fusion. Patients are most commonly assessed immediately at the time of injury. Muscle testing is commonly performed using Medical Research Grading System (MRC). Although complete neurologic stabilization may not be complete until 2 years post-injury, in the group with initial grade 0 muscle strength after the acute phase of injury, expectations of improved muscle strength to or beyond grade 3 after 4-6 months is minimal. And grade 3 muscle strength is felt to be the minimum useful functional strength in a muscle group. The investigators propose an early nerve reconstruction approach to the tetraplegic patient with dysfunction of the upper extremity to augment the available tendon transfers. A comparative pilot study is proposed to determine the effectiveness of supinator branch to posterior interosseous nerve (PIN) transfer in 5 patients with cervical spine injury. Patient who fits inclusion criteria will be offered the opportunity to be involved in the study and reviewed at 6 months from injury. If the patient still has not regained Grade 3 power in finger or thumb extension, they will be randomized to be in a surgical group or non-surgical group. If informed consent is obtained, then surgery will be completed between 6-9 months from the patient's original cervical spine injury. The patient will be followed at regular intervals post-operatively with expectation of 18-24 month follow-up. Measures will be used pre and post-operatively for comparison. Measures will include MRC muscle grade (EDC), range of motion, Disability of the Arm, Shoulder, and Hand Questionnaire (DASH), and The Graded Redefined Assessment of Strength Sensibility and Prehension (GRASSP) (Kalsi-Ryan, 2011).
