The Study of a Neural Interface and a Neurostimulation in the Rehabilitation of Upper Limb Movement...
StrokeSpinal Cord InjuriesThe aim of the study is to investigate the effectiveness of a new rehabilitation technology for paralysis that occurs after stroke or spinal cord injury. The research will jointly use a prototype neurorehabilitation orthosis, in which a robotic device moves a paralyzed arm at the command of a non-invasive brain-computer interface to perform a game life-like task augmented using a virtual-reality display, as well as an electrical stimulation device that activates the spinal cord and/or muscles of the paralyzed arm. Investigators expect that a portion of the patients participating in the study will have an improvement in arm mobility by the end of the study. Participants who express their special written consent will have venous blood tests conducted three times for subsequent analysis of lipid biomarkers, in order to further evaluate the effectiveness of rehabilitation methods based on biochemical analysis.
The Effect of NMES on Bowel Management in People With Chronic SCI
Electric Stimulation TherapyBowel Dysfunction2 moreIt has been reported that 62% of all people with Spinal Cord Injury (SCI) have experienced faecal incontinence and that neurogenic bowel dysfunction (NBD) is a major sequela. As an alternative to abdominal massage or the use of suppositories, the electrical stimulation (ES) of the abdominal wall has been shown to be effective in decreasing the bowel transit time as well as decreasing constipation in children with slow-transit constipation. Due to the intrinsic nature of the guts' innervation, we expect to reproduce these positive effects in people with SCI through administration of neuromuscular electrical stimulation (NMES).
Functional Electrical Stimulation (FES) and Reconstructive Tetraplegia Hand and Arm Surgery
Spinal Cord Injury CervicalFES is a common and established method in the rehabilitation of persons with spinal cord injury (SCI). Some known effects of FES were investigated in several studies e.g. avoiding disuse and denervation atrophy, improving muscle force, power output and endurance changing muscle fibre type, increasing cross sectional area of muscle, increasing muscle mass, activation of nerve sprouting, reducing spasticity and motor learning. Most of the studies investigated the impact of FES in the lower limbs. For the upper extremities fewer studies exist. However, it is supposed that the effects of FES are similar. In the rehabilitation of persons with tetraplegia, FES, especially the stimulation of the upper extremities triggered by electromyography (EMG) is an established method to generally improve hand and arm function. However, none of those studies has investigated the effect of FES in combination with reconstructive tetraplegia hand surgery. Improved muscle strength is supposed to improve the functional outcome in participation. Additionally, FES could increase the motor learning process. Supported by the clinical observation we hypothesize that FES has a positive influence on the outcome of surgical reconstruction of tendon and/or nerve transfers.
Mild Intermittent Hypoxia and Its Multipronged Effect on Sleep Apnea
Obstructive Sleep ApneaSpinal Cord InjuriesMild intermittent hypoxia (IH) initiates sustained increases in chest wall and upper airway muscle activity in humans. This sustained increase is a form of respiratory plasticity known as long-term facilitation (LTF). Repeated daily exposure to mild IH that leads to the initiation of LTF of upper airway muscle activity could lead to increased stability of the upper airway. In line with PI's laboratory's mandate to develop innovative therapies to treat sleep apnea, this increased stability could ultimately reduce the continuous positive airway pressure (CPAP) required to treat obstructive sleep apnea (OSA) and improve compliance with this gold standard treatment. Improved compliance could ultimately serve to mitigate those comorbidities linked to sleep apnea. Moreover, in addition to improving CPAP compliance numerous studies indicate that mild IH has many direct beneficial effects on cardiovascular, neurocognitive and metabolic function. Thus, mild IH could serve as a multipronged therapeutic approach to treat sleep apnea. In accordance with this postulation, our proposal will determine if repeated daily exposure to mild IH serves as an adjunct therapy coupled with CPAP to mitigate associated co-morbidities via its direct effects on a variety of cardiovascular, metabolic and neurocognitive measures and indirectly by improving CPAP compliance. Modifications in autonomic (i.e. sympathetic nervous system activity) and cardiovascular (i.e. blood pressure) function will be the primary outcome measures coupled to secondary measures of metabolic and neurocognitive outcomes.
NEUROwave - Extracorporeal Shock Wave Therapy (ESWT) in Acute Traumatic Complete (AIS A) and Incomplete...
Acute Traumatic Spinal Cord InjuryIt has been hypothesized that there are two mechanisms of acute traumatic spinal cord injury (SCI): the primary mechanical damage and the secondary injury due to additional pathological processes initiated by the primary injury. Neurological damage due to laceration, contusion, distraction or compression of the spinal cord is called ''primary injury''. This mechanical injury leads to a cascade of biochemical and pathological changes, described as ''secondary injury'', which occurs minutes to weeks after the initial trauma and causes further neurological deterioration. This secondary cascade involves vascular changes, an inflammatory response, neurotoxicity, apoptosis and glial scarring, and further compromises neurological impairment after traumatic spinal cord injury. Edema, ischemia and loss of autoregulation continue to spread bi-directionally from the initial lesion along the spinal cord for up to 72 hours after the trauma. It has been postulated that the damage caused by the primary injury mechanism is irreversible and therapeutic approaches in recent years have focused on modulating the secondary injury cascade. Researchers found significantly greater numbers of myelinated fibers in peripheral nerves after a single ESWT application in an experimental model on rats after a homotopic nerve autograft into the sciatic nerve. In another study a spinal cord ischemia model in mice was performed. ESWT was applied immediately after surgery and the treated animals showed a significantly better motor function and decreased neuronal degeneration compared to the control group within the first 7 days after surgery. Researchers investigated the effect of low-energy ESWT for the duration of three weeks on a thoracic spinal cord contusion injury model in rats. Animals in the ESWT group demonstrated significantly better locomotor improvement and reduced neuronal loss compared to the control animals at 7, 35, and 42 days after contusion. It has been postulated previously, that ESWT improves the metabolic activity of various cell types and induces an improved rate of axonal regeneration. ESWT might be a promising therapeutic strategy in the treatment of traumatic SCI. The underlying study aims to investigate the effect of ESWT after acute traumatic spinal cord injury in humans within 48 hours of trauma in order to intervene in the secondary injury phase with the objective to reduce the extent of neuronal damage.
CREATION: A Clinical Trial of Qigong for Neuropathic Pain Relief in Adults With Spinal Cord Injury...
Spinal Cord InjuriesBetween 39-67% of the 294,000 Americans who have a SCI suffer from long-term debilitating neuropathic pain, interfering with rehabilitation, general activity, mobility, mood, sleep, and quality of life. Pain can hinder any potential for functional improvement that could be obtained during rehabilitation. Yet, neuropathic pain is refractory to many treatments. Current interventions, such as medications and physical therapy, result in less than 50% reduction in pain for only about one third of the people trying them, calling for new treatment options. Qigong, a mind and body approach that incorporates gentle body movements, paired with a focus on breathing and body awareness to promote health and wellness, could reduce SCI-related neuropathic pain. If the hypothesis is supported, the resulting work could be transformative in demonstrating a potentially effective therapy for civilians, military Service members, and Veterans with SCI and neuropathic pain. The following provides the scientific basis for this hypothesis and establishes the rationale for this approach. This study also includes an optional, remote, quasi-experimental substudy, in which all participants will receive Qigong for 12 weeks, followed by 6 weeks followup.
Spinal Cord Stimulation (SCS) for Spinal Cord Injury (SCI)
Spinal Cord Injury at T1-T12 LevelTraumatic Thoracic Spinal Cord Contusion4 moreThe purpose of this feasibility study is to compare the impact of Spinal cord stimulation [SCS] for Spinal Cord Injury (SCI) pain and rehabilitation. SCS, also known as Epidural Electrical Stimulation (EES), will be utilized along with conventional medical management (CMM) or CMM alone. Participation in this research study is expected to last approximately 12 months. All subjects will be evaluated and proceed with implantation of two SCS devices- one tailored based on the individual's SCI for the treatment of neuropathic pain of trunk and limb and a second near the bottom of the spinal cord (conus region) to study the impact on motor, sensory, bowel/bladder outcomes. All patients will also continue receiving CMM, such as medications and physical therapy. Participating subjects will be randomly assigned to one of two treatment groups: Placebo arm: SCS OFF + CMM. Under the direction of the study physician, the patient may receive a variety of treatments, such as medications and various forms of rehabilitation. Treatment arm: SCS ON + CMM. The study treatment Spinal Cord Stimulation [SCS]: the study physician will perform a trial procedure to see if the study procedure works for the patient and may implant a permanent device if it is successful. There is a temporary trial procedure, or a "test drive," which usually lasts 5-7 days. If this is successful, patients will discuss a more permanent implant. This study involves the concurrent placement of two SCS devices (one focused on pain and the second for rehabilitation). For three months, treatment group subjects will have the SCS turned on and will have rehabilitation as part of their CMM. Participants in the placebo arm will have their SCS remain off and will undergo CMM with rehabilitation therapy similar to the treatment group. Neither the subjects nor the treatment team will know which patients are in the treatment or placebo arm. At the end of three months, the study group will be revealed and the placebo group subjects will be allowed to crossover and have their SCS turned on. Rehabilitation visits may be remote and the study duration is approximately 12 months. There may be additional blood tests and clinical exams to collect data on the effectiveness of the therapy. Data at follow-up visits will be compared to the subjects' baseline data and that of the control group at the respective visits.
Identifying Body Awareness-related Brain Network Changes During Cognitive Multisensory Rehabilitation...
Spinal Cord InjuriesNeuropathic PainMany adults with spinal cord injury (SCI) suffer from long-term debilitating neuropathic pain. Available treatments, including opioids, are ineffective at eliminating this pain. Based on preliminary data from Dr Morse and from Dr Van de Winckel, we have demonstrated that brain areas that are important for body awareness and pain perception (parietal operculum, insula) have weaker brain connectivity in adults with spinal cord injury than in able-bodied healthy adults and that Cognitive Multisensory Rehabilitation (CMR) can restore these networks. This study uses a cross-over study for adults with SCI and a comparison of baseline outcomes in adults with SCI vs able-bodied healthy adults to address two aims: AIM 1: Determine baseline differences in resting-state and task-based fMRI activation and connectivity in adults with SCI compared to able-bodied healthy controls. AIM 2: Identify changes in brain activation and connectivity, as well as behavioral outcomes in pain and body awareness in adults with SCI after CMR versus standard of care.
