Filter by:Dyspnea is "a subjective experience of breathing discomfort that consists of qualitatively distinct sensations that vary in intensity". It is known that sensory information from the respiratory system activates regions of the cerebral cortex to produce the perception of dyspnea but far less is known about the neurophysiology of dyspnea than about vision, hearing, or even pain. Dyspnea likely arises from multiple nervous system sources, but the exact locations have not been well identified. Investigations of the mechanisms underlying respiratory sensations have included studies of airway anesthesia, chest wall strapping, exercise, heart-lung transplantation, hyperventilation, and opioid use. Study of the perception of breathing sensations in individuals with a spinal cord injury presents additional opportunity. The goal of the proposed project is to examine the effects of increasingly severe levels of spinal cord injury on the perception of breathing sensations in participants who are able to breathe without the use of a ventilator. The investigators hypothesize that the perception of breathing varies with the extent of somatosensory information that reaches cerebral cortex.
This is an HDE probable benefit, open-label, non- randomized, single-arm, multicenter study to evaluate the safety and probable benefit of the poly(lactic-co-glycolic acid)-b-poly(L-lysine) Scaffold ("Scaffold") in subjects with thoracic AIS A traumatic spinal cord injury at neurological level of injury of T2-T12.
In this study the following hypotheses will be tested: Electrical stimulation of the gluteal muscle (buttocks) leads to 1. an increase in the thickness of the gluteal muscle 2. a decrease in the thickness of the fat of the buttock area 3. a change in the distribution of the middle and maximal seating pressure to a more consistent pressure 4. an increase in well-being of the patients.
The aim of this study will be to evaluate the safety and the efficacy of a new robotic exoskeleton device in subjects with Spinal Cord Injury (SCI) and in subjects with other neurological disease with an impairment of lower limbs.
The main objective of the intervention in the study is devise feasibility using high-count microelectrode arrays implanted into peripheral nerves of patients with limb amputations or peripheral nerve injury. These microelectrodes will be custom-made and are not available for commercial distribution. The investigators hypothesize that recording neural signals from a large number of microelectrodes will provide selective motor information in high enough numbers to allow control over future artificial devices with many moving parts, i.e. artificial limbs with shoulder, elbow, wrist, and/or individual fingers that move. These studies will also investigate to what extent microstimulation of nerve fibers can provide sensory feedback from a prosthetic limb. The investigators will also conduct up to three acute surgeries where a Utah slanted Electrode Array (USEA) will be implanted in volunteers who are about to undergo limb amputations. These acute implantations will provide Dr. Hutchinson with human surgical experience in implanting USEAs and evaluating the containment system we will be using to immobilize the implanted USEA in the nerve.
In this study, an FDA-cleared device and type of treatment called "AMES," which stands for Assisted Movement with Enhanced Sensation, will be used to determine whether sensation in the upper limb of individuals with incomplete spinal cord injuries, acquired brain injury, or stroke improves along with movement through treatment. We hypothesize that measureable improvement in the sensation of the upper limb will precede improvement in functional movement.
The study investigates the effect of using transcranial direct current stimulation (tDCS) and skilled stepping training versus skilled stepping training with sham-tDCS in improving ankle and leg motor control in persons with ambulatory persons with spinal cord injury. Hypotheses H1: Participants will display greater improvement in stepping function following tDCS combined with training compared to sham-tDCS and training. H2: Participants will display greater gains in cortical excitability, as evidenced by lower cortico-motor threshold (MT) associated with the TA muscles following tDCS and training compared to following sham stimulation and training. H3: Participants in the tDCS+training group will show greater increases walking speed in a timed 10 meter walking trial. H4: Participants in the tDCS+training group will show be able to perform a greater number of toe-taps test.
The principal aim of this study was to establish the feasibility of rapid administration, safety, and tolerability of AC105 in patients with acute spinal cord injury.
The purpose of this study is to determine the long term safety and preliminary efficacy of intramedullary transplantation of HuCNS-SC cells in subjects with thoracic spinal cord trauma.
This phase II/III clinical trial is designed to evaluate the safety and efficacy of autologous Mesenchymal Stem Cells (MSC) transplanted directly into the injured spinal cord.
