Filter by:The purpose of this study is to demonstrate high definition non-invasive neuromuscular stimulation of an upper extremity in tetraplegic participants.
Vibration therapy is a possible alternative to drug-based treatments for spasticity following SCI. Research indicates that it may provide temporary relief from spasticity, but many interventions under investigation are not portable and therefore access is limited. The aim of this study is to investigate the feasibility of using a portable vibrating device to decrease UE spasticity.
The purpose of this research is to test the feasibility of an intervention using biofeedback to treat stress and anxiety among individuals with tetraplegia. The expected duration of participation in this study is about 5 hours over the course of about 5 weeks. Participants will be randomly assigned to either a biofeedback training intervention or a control group. After completing questionnaires, participants will undergo physiological monitoring for the purpose of measuring heart rate and breathing. Those assigned to the biofeedback group will undergo 20 minutes of physiological monitoring while also participating in biofeedback training twice a week for 4 weeks (8 sessions) from home. Those assigned to the control group will undergo 20 minutes of physiological monitoring twice a week for 4 weeks (8 sessions) from home, but will not receive biofeedback training. Each session is expected to last 30 minutes to allow for completion of questionnaires over the the phone prior to and following each training session. It is hypothesized that the biofeedback intervention will demonstrate high feasibility and compared to those in the control group, participants who receive the biofeedback intervention will attain greater pre-post reductions in both physiological and self-reported stress.
In the last decade the stimulation of denervated muscles got more attention. Not at least because of the promising results of the RISE project (Use of electrical stimulation to restore standing in paraplegics with long-term denervated degenerated muscles). In this European project it was shown that electrical stimulation of denervated muscles in spinal cord injuries (SCI) increased muscle mass and improved the trophic situation of the lower extremities. Furthermore, structural altered muscle into fat- and connective tissue could be restored into contractile muscle tissue by stimulation. However, only a few studies investigated the effect of direct muscle stimulation in case of peripheral nerve damage in the upper extremities. None investigated the stimulation effect in denervated or partially denervated muscles in the upper extremities in tetraplegic patients.
This study is for people who have a paralyzed arm and hand from a spinal cord injury, who have also received a recording electrode array in the brain as part of the BrainGate study. The study will look at the ability of these participants to control different grasping patterns of the hand, both in virtual reality and in his/her actual hand. Movement of the participant's hand is controlled by a functional electrical stimulation (FES) system, which involves small electrodes implanted in the arm, shoulder and hand that use small electrical currents to activate the appropriate muscles.
A repetitive, non-invasive brain stimulation technique referred to as theta burst stimulation can modulate corticomotor excitability and therefore has great rehabilitative potential for individuals with neurologic deficits, including individuals with spinal cord injury (SCI). In particular, intermittent theta burst stimulation (iTBS) can increase corticomotor excitability and may be a useful adjunct to physical rehabilitation to promote motor re-education after upper limb reconstruction in individuals with tetraplegia. Upper limb reconstruction involves surgical transfer of a non-paralyzed tendon or nerve with a redundant or less important function to perform a more critical function. Upper limb reconstruction is intended to help individuals achieve their goals related to activities of daily living and independence in the community. Outcomes after reconstruction are variable and depend largely on the efficacy of motor re-education of the transferred muscle to perform a new function. The long-term goal of our research is to determine whether iTBS combined with physical rehabilitation can improve motor re-education after reconstruction. As a first step, the purpose of this proposal is to determine the effect of iTBS on corticomotor excitability of proximal muscles in nonimpaired individuals and two groups of individuals with tetraplegia: individuals with and without upper limb reconstruction.
Research indicates that increasing brain excitability might help improve hand function in people with spinal cord injury. Brain stimulation that uses electrodes placed on the surface of the scalp (also called "non-invasive brain stimulation") increases brain excitability and has the potential to make it easier for the brain and nervous system to respond to arm and hand training. The purpose of this study is to compare four different types of stimulation for increasing brain excitability to determine which types are best for helping people with tetraplegia improve their ability to use their arms and hands. To fully evaluate the value of brain stimulation on arm and hand function, the investigators will also evaluate the effect of sham (fake) stimulation. Each participant will receive a single session of each of the five types of stimulation being tested.
There are over 44,000 persons living with spinal cord injury (SCI) in Canada, who face substantial challenges in maintaining a healthy body composition after injury. As a result, obesity, diabetes and cardiovascular disease are prevalent in this population. Guidelines indicating that twice weekly 20-minute sessions of exercise (plus resistance training) will increase physical fitness in those with SCI have been recently published. However, no SCI-specific guidelines indicating the volume of exercise to reduce the risk of developing obesity-related diseases exist. Longitudinal studies indicate that a weekly exercise-related energy expenditure of 2000 - 2500 Calories is correlated with the least likelihood of cardiovascular disease in the able-bodied population. There is little information regarding energy expenditure (EE) for activities carried out by persons with SCI, with less available for persons with tetraplegia. Once known, this EE data can be used to develop exercise interventions to determine the volume of voluntary exercise required to reduce obesity and risk factors for diabetes and cardiovascular disease in those living with tetraplegia.
The aim of the study was to evaluate the tetraplegics movement strategies, assisted by Neuromuscular Electrical Stimulation (NMES), on the reach and palmar (RP) grasp to different weights objects.Tetraplegics had their RP grasp movement captured by four infrared cameras and 6-reflexive markers attached on the trunk and right arm, assisted or not by NMES, in the triceps, extensor carpi radialis longus, extensor digitorum communis, flexor digitorum superficialis, opponens pollicis and lumbricalis muscles. The grasp was made in three cylindrical objects (different diameters and weights) placed in trunk midline in an equivalent distance of the arm's length. The patients were able to reach and made palmar grasp in all cylinders using the stimulation sequences assisted by NMES.
Single center, pilot study, to evaluate the influence of Motor Imagery (MI) on functional rehabilitation and cerebral plasticity through the qualitative and quantitative mental practice approach. For this, the investigators will use magnetoencephalography (MEG) but also physiological and behavioral indicators developed by the Laboratoire de la Performance Motrice, Mentale et du Matériel (P3M) of Université Claude Bernard Lyon 1 and its partners.
