Pulsed Magnetic Stimulation - Managing Spasticity in Spinal Cord Injury
Spinal Cord InjuriesSpasticity (tightening, spasming and/or contractions of muscles) is a commonly encountered consequence of injuries to the central nervous system. Spasticity has an adverse effect on quality of life and function of patients with spinal cord injuries, stroke and cerebral palsy. Conventional management consists of medication, injections of botulinum toxin and occasionally extensive surgical interventions. Several studies have examined the use of repetitive magnetic stimulation of the brain and of peripheral nerves to produce long-term depression of spasticity. Recently, Theta burst sequence low-dose magnetic stimulation has been shown to mark unused synaptic connections for deletion. By using pulsed magnetic stimulation of the spinal cord the abnormal connections arising from injury may be identified for deletion, therefore potentially minimising the mis-firing circuits. The investigators plan, in this pilot study, to test whether firstly the application of pulsed magnetic stimulation of the spinal cord is achievable in patients with spinal cord injury (SCI) and secondly whether it has an effect on lower limb spasticity. These results will be used to help design a larger trial, to expand the numbers of participants and variety of pathologies treated. Participants (in-patients at the Midland Centre for Spinal Injuries) with stable SCI will be randomised to receive either intermittent pulsed magnetic stimulation or no stimulation. Patients will be blinded as to whether they are receiving stimulation (the machine will be active up and placed in the same position for both groups, except the sham group will have the stimulation coil applied in an orientation that does not deliver the magnetic field to the spinal cord).

DiSCIoser: Improving Arm Sensorimotor Functions After Spinal Cord Injury Via Brain-Computer Interface...
Spinal Cord InjuriesMotor DisordersThe goal of this clinical trial is to validate the efficacy of a Brain-Computer Interface (BCI)-based intervention for hand motor recovery in subacute cervical spinal cord injured (SCI) patients during rehabilitation. The study will provide evidence for the clinical/neurophysiological efficacy of the BCI intervention as a means to promote cortical sensorimotor plasticity (remote plasticity) and thus maximize recovery of arm functions in subacute cervical SCI. Participants will undergo an extensive clinical, neurophysiological, neuropsychological and neuroimaging assessment before and after a BCI training based on motor Imagery (MI) of hands. The intervention will be delivered with a system that was originally validated for stroke patients and adapted to the aims of this study. Researchers will compare the BCI intervention with an active MI training without BCI support (active comparator).
Neuropathic Pain and Operant Conditioning of Cutaneous Reflexes After SCI
Spinal Cord InjuriesNeuropathic Pain2 moreThe purpose of the second part of the study is to examine the effect of reflex training in the leg to decrease neuropathic pain. For this, the researchers are recruiting 15 individuals with neuropathic pain due to spinal cord injury to participate in the reflex training procedure. The study involves approximately 50 visits with a total study duration of about 6.5 months (3 months for baseline and training phases followed by 1 month and 3 month follow-up visits).

Transcranial Magnetic Stimulation for Chronic Neuropathic Pain
Chronic Neuropathic PainPost-Stroke Pain8 moreChronic neuropathic pain is defined as pain caused by a lesion or disease of the somatosensory nervous system. It is highly prevalent, debilitating, and challenging to treat. Current available treatments have low efficacy, high side effect burden, and are prone to misuse and dependence. Emerging evidence suggests that the transition from acute to chronic neuropathic pain is associated with reorganization of central brain circuits involved in pain processing. Repetitive transcranial magnetic stimulation (rTMS) is a promising alternative treatment that uses focused magnetic pulses to non-invasively modulate brain activity, a strategy that can potentially circumvent the adverse effects of available treatments for pain. RTMS is FDA-approved for the treatment of major depressive disorder, obsessive-compulsive disorder, and migraine, and has been shown to reduce pain scores when applied to the contralateral motor cortex (M1). However, available studies of rTMS for chronic neuropathic pain typically show variable and often short-lived benefits, and many aspects of optimal treatment remain unknown, including ideal rTMS stimulation parameters, duration of treatment, and relationship to the underlying pain etiology. Here the investigators propose to evaluate the efficacy of high frequency rTMS to M1, the region with most evidence of benefit in chronic neuropathic pain, and to use functional magnetic resonance imaging (fMRI) to identify alternative rTMS targets for participants that do not respond to stimulation at M1. The central aim is to evaluate the pain relieving efficacy of multi-session high-frequency M1 TMS for pain. In secondary exploratory analyses, the investigator propose to investigate patient characteristic that are predictive of responsive to M1 rTMS and identify viable alternative stimulation targets in non-responders to M1 rTMS.
Duroplasty for Injured Cervical Spinal Cord With Uncontrolled Swelling
Spinal Cord InjuriesQUESTION. Does duroplasty improve outcome after spinal cord injury? WHAT DO WE STUDY? We will investigate whether performing a surgical procedure called duroplasty improves outcomes after spinal cord injury. WHY SPINAL CORD INJURY? Spinal cord injury is a devastating condition that causes permanent disability such as paralysis, numbness and loss of bladder and bowel control. Currently, there are no treatments shown to improve outcome after spinal cord injury. WHAT IS DUROPLASTY? Duroplasty is an operation that involves opening the tough membrane around the cord, called the dura, and stitching a patch of artificial dura to expand the space around the swollen cord. WHY IS DUROPLASTY BEING STUDIED? Based on our preliminary evidence, we think that the dura causes cord pressure after injury. We have shown in a small study of patients that performing this operation safely and effectively reduces pressure on the injured cord. WHO IS ELIGIBLE? Adult patients with severe spinal cord injuries in the neck who will have surgery within 72 hours. WHAT TREATMENT? Those who agree to take part will be allocated by chance (like tossing a coin) to standard treatment or standard treatment plus duroplasty. Some patients will also be asked to take part in a smaller study that involves placing probes at the injury site. WHERE? We will recruit patients from U.K. Major Trauma Centres. Most assessments will be done in U.K. Spinal Injury Centres. Later on, we may recruit from overseas. HOW LONG? We aim to recruit 222 - 260 patients over 4 years. Patients will be followed up for a year. WHAT DO WE ASSESS? Patients will be assessed (using questionnaires and by examination) how well they can use their hands, walk, control their bladder and bowel and their quality of life. Some of these assessments will be repeated at 3, 6 and 12 months after surgery. WHAT IS THE OPTIONAL MECHANISTIC STUDY? DISCUS includes an optional study for at least 50 patients who will take part in the randomised controlled trial. The aim of the mechanistic study is to determine how duroplasty improves outcome, i.e. whether duroplasty reduces cord compression, improves blood flow to the injured cord perfusion, improves cord metabolism and reduces cord inflammation. WHAT IS THE OPTIONAL INFORMATION STUDY? For the first two years, a study called QuinteT Recruitment Intervention (QRI) is designed to optimise patient recruitment and informed consent in the trauma setting.
