This research seeks to demonstrate Neuralis' potential in revolutionizing assistive technology by offering a non-invasive, user-friendly solution for individuals facing motor impairments, ultimately enhancing their quality of life.
The Synchron motor neuroprosthesis (MNP) is intended to be used in subjects with severe motor impairment, unresponsive to medical or rehabilitative therapy and a persistent functioning motor cortex. The purpose of this research is to evaluate safety and feasibility. The MNP is a type of implantable brain computer interface which bypasses dysfunctional motor neurons. The device is designed to restore the transmission of neural signal from the cerebral cortex utilized for neuromuscular control of digital devices, resulting in a successful execution of non-mechanical digital commands.
Study objective The purpose of this clinical research is to verify if the patient with chronic stroke can regain the ability of living independently after daily using Testa BioHealing® Biophoton Generators to increase the energy of the brain and other parts of the body. Study design This study is a randomized, triple-blinded, placebo-controlled prospective intervention clinical research. At least 46 patients with chronic stroke will participate in the live-in observational study in a Tesla MedBed Center. Study patient population The adult patient with a chronic stroke which was defined as a stroke occurred at least 6 months ago with a significant disability unable to have an independent life, is to be considered as a qualified participant.
The purpose of this clinical research is to verify if the patients with chronic stroke can regain the ability of living independently after daily using Testa BioHealing® Biophoton Generators to increase the energy of the brain and other parts of the body. The main study questions are: * Can patients with chronic stroke regain life independence by normalizing Activities of Daily Living (ADL). * Can brain-injury and recovery status of the patients with chronic stroke be detected by using an EEG machine. Participants will sleep-rest on a hotel bed energized by Tesla BioHealing Biophoton Generators, and clinical study staff will observe the participant's activities of daily living, as compared to those who will sleep in the hotel room equipped with placebo devices.
To determine whether treatment with transauricular vagus nerve stimulation (taVNS) during the training of an affected upper limb of a patient with chronic stroke on a robotic motor task alters the motor impairment.
A scientific study is being done to test a special treatment for people who have spasticity or tight muscles. This treatment is called "stereotactic radiosurgery dorsal rhizotomy." It uses very accurate beams of radiation to target certain nerves in the back to help loosen up the muscles. In this study, people are put into two groups by chance: one group gets the real treatment, and the other group gets a "fake" treatment that doesn't do anything. This fake treatment is called a "sham." Doing this helps make sure the study is fair and the results are true. After the people in the study get their treatment, the researchers will watch and see how they do. They will check if their muscles are less stiff and if they have any side effects. By looking at the results from both groups, the researchers can find out if the special treatment really helps people with spasticity. Patients who got the "fake" treatment will be eligible to receive the "real" treatment after 6 months.
This study examines the effect of non-invasive brain stimulation targeting different brain areas on movement of the affected arm post-stroke. Participants will receive stimulation to each of 3 different brain areas combined with a session of arm exercise.
People who have had a stroke often have difficulty walking and problems with their balance. The purpose of this project is to examine problems with foot postures in people who have weakness on one side of their body
This is an early feasibility trial to determine whether transcutaneous neuromuscular electrical stimulation, with or without transcutaneous spinal cord stimulation, using an investigational neurostimulation device improves functional arm/hand movements in individuals with paralysis or paresis due to a spinal cord injury or stroke and improves functional arm/hand or leg/foot movements in individuals with paralysis or paresis due to other brain or nerve injuries. In this study, eligible individuals that agree to participate will be asked to attend up to 5 study sessions a week for 1 year (depending on participant availability), with each session lasting up to 4 hours. At the first study session, participants will have their demographic information collected, vital signs assessed, and have measurements performed of their limbs and torso, as appropriate. They will also undergo clinical evaluations and tests to assess their current functional movement and sensation capabilities. During subsequent study sessions, participants will undergo many tasks designed to improve functional movements in paralyzed limbs. Specifically, participants will receive neuromuscular electrical stimulation to the limb(s) and/or electrical stimulation to the spinal cord to evoke specified movements. The stimulation parameters and locations on the spinal column and/or limb(s) that evoke specific movements will be noted. The movements will be assessed with visual inspection, electromyography, and/or sensors. The clinical evaluations and tests to assess functional movement and sensation capabilities will be repeated throughout the study and at the last study session to assess for functional improvements compared to the first study session. Upon completion of these study sessions, the individual's participation in the study is considered complete.
The purpose of the research is to develop a new medical device prototype to restore functional movement of an arm made weak due to a chronic stroke
This is a Phase III clinical trial to compare the efficacy of two dosages of a new infant rehabilitation protocol - I-ACQUIRE - to usual and customary forms of infant rehabilitation in infants who experienced Perinatal Arterial Stroke (PAS).
This research study is to find out if brain stimulation at different dosage level combined with an efficacy-proven rehabilitation therapy can improve arm function. The stimulation technique is called transcranial direct current stimulation (tDCS). The treatment uses direct currents to stimulate specific parts of the brain affected by stroke. The adjunctive rehabilitation therapy is called "modified Constraint-Induced Movement Therapy" (mCIMT). During this therapy the subject will wear a mitt on the hand of the arm that was not affected by a stroke and force to use the weak arm. The study will test 3 different doses of brain stimulation in combination with mCIMT to find out the most promising one.
This is a feasibility study to alter the Microsoft Kinect software to be used as a rehabilitation tool. The prototype used is still in the early developing stage. The purpose of this research study is to develop a prototype of altered Microsoft Kinect Software and determine its use in improving the function of the study subjects' weaker extremities. The altered software will allow a viewing of the mirror image of the involved limb as it is moved. However, the image that is viewed will reflect normal movement even if the limb cannot move normally. By viewing normal movement of the weaker limbs the "mirror neuron" network in the brain will become activated and will ultimately improve the function of the weaker side.
The goal of this study is to characterize individual responses to a single application of transcranial direct current stimulation (tDCS) in children with unilateral cerebral palsy (UCP), and to test which electrode configuration produces changes in brain excitability and motor function. Participants with UCP, ages 7-21 years, will be assigned to one of four tDCS groups. Using single-pulse transcranial magnetic stimulation, the investigators will assess cortical excitability before and at regular intervals up to 1 hour following tDCS. The knowledge gained from this study will advance the field through more targeted approaches of neuromodulatory techniques in this population and others, using individual characteristics to guide optimal treatment
A study of stereotactic, intracerebral injection of CTX0E03 neural stem cells into patients with moderate to moderately severe disability as a result of an ischemic stroke.
The purpose of this study is to evaluate if 5 consecutive sessions of PathMaker anodal DoubleStim treatment, which combines non-invasive stimulation of the spinal cord (tsDCS- trans-spinal direct current stimulation) and of the median nerve at the peripheral wrist (pDCS-- peripheral direct current stimulation), can significantly reduce spasticity of the wrist and hand after stroke.
The investigators ultimate goal is to personalize brain stimulation for stroke so outcomes of the upper limb can be maximized for each individual patient. Several groups including the investigators have recently theorized that personalizing stimulation so as to selectively stimulate iM1 in mild, and cPMd in patients with greater severity would help generalize benefits of stimulation. The investigator premise that variances in expressions of plasticity can explain how to best stratify patients for robust, personalized stimulation.
In stroke rehabilitation, unilateral training of the impaired limb after stroke is often the frequent strategy used over bilateral ones. However, the clinical need for bilateral training is supported by evidence that shows that unilateral training of the impaired limb does not automatically restore bimanual coordination and function. Increased focused is needed on developing more robot-assisted therapy that can train the impaired arm bilaterally and unilaterally. Controlling these robots is often difficult and requires a better understanding of the coupling effects of the left and right hand before and after a stroke. There is a need to develop robot-assisted therapy devices that can address coupled and uncoupled bimanual movements as well as symmetry as well as asymmetry in context of human bimanual actions along with the intermanual division of labor in various ADL tasks. This study focuses on bilateral training and the use of bio-inspired control algorithms to understand impairment and recovery on Bimanual Activities of Daily Living (ADLs) by stroke subjects in terms of the arm kinematics. Healthy subjects and those with hemiplegia due to a stroke or cerebral palsy will be evaluated by a member of the research team and asked to perform a battery of tasks to test the viability and usability of a bilateral robot system called BiADLER, which allows patients to complete daily tasks with varying levels of assistance to adapt task performance to each individual subject's performance. Subjects will to provide feedback to the researchers on their observations and thoughts about the therapy devices.
Rehab in a Crate is a therapy gym designed to be affordable, compact and easily transportable. The purpose of this particular study is to gain feedback on the initial design of the Rehab in a Crate system. This will be accomplished by using qualitative ethnographic research methods (i.e. human centered design) in the form of surveys that have been carefully designed by members of the research team. The eligibility criteria of this survey research reflects the intended user base of an eventual finished product, which is survivors of stroke and cerebral palsy across the globe. And while healthcare professionals are not the user base per se, their expertise and feedback should be instrumental in the design of future iterations of the Rehab in a Crate. Ease of use, utility, design, and various features, both existing and intended, will all be surveyed items.
The specific aims of this study are: 1. To determine if Human Umbilical Cord Blood (hUCB) infusion is safe in children with perinatal arterial ischemic stroke (AIS). 2. To determine if late functional outcome, physiologic response, and anatomic findings are changed following hUCB infusion in children with perinatal AIS.
The purpose of this research study is to evaluate the effectiveness of functional electrical stimulation (FES) provided by an implanted pulse generator (IPG) in correcting hip, knee and ankle function to improve walking in people with partial paralysis.
The purpose of this study is to investigate whether benefits of training the affected hand in patients with stroke can be improved by combining training with a painless, noninvasive technique called Transcranial Direct Current Stimulation (TDCS). TDCS will be applied over the part of the brain responsible for movements of the affected hand. Also, the investigators will study the changes in the brain that favor recovery of hand function following combination of training and tDCS.
The purpose of this research study is to demonstrate that individuals with upper limb paralysis due to spinal cord injury, brachial plexus injury, amyotrophic lateral sclerosis and brain stem stroke can successfully achieve direct brain control of assistive devices using an electrocorticography (ECoG)-based brain computer interface system.
The purpose of this study is to determine if individuals who had a stroke more than one year before entering the study and who remain unable to open their affected hand are better able to sense and move their affected arm after 10-15 weeks of treatment with a new robotic therapy device (the AMES device) and EMG biofeedback.
This study will gain information on methods of control of a prosthetic arm in stroke patients or traumatic brain inury patients through a technique called "brain-computer interface" (BCI). BCI allows for direct communication between man and machine. Brain cells communicate by producing electrical impulses that help to create such things as thoughts, memory, consciousness and emotions. In BCI, brain waves are recorded by an electroencephalogram (EEG) through electrodes (small wires) attached to the scalp. The electrodes measure the electrical signals of the brain. These signals are sent to the computer, which translates them into device control commands as messages that reflect a person's intention. This type of brain activity comes from the sensorimotor areas of the brain and can be controlled through voluntarily training to control the hand prosthesis through the BCI. Healthy normal volunteers and people who have had a stroke or traumatic brain injury more than 12 months ago and have paralysis in the right or left arm, hand or leg and who are between 18 and 80 years of age may be eligible for this study. Candidates are screened with a clinical and neurological examination and magnetic resonance imaging (MRI) of the brain. MRI uses a magnetic field and radio waves to obtain images of the brain. The scanner is a metal cylinder surrounded by a strong magnetic field. During the procedure, the subject lies in the scanner for about 45 minutes, wearing ear plugs to muffle loud knocking sounds that occur with the scanning. Participants undergo the following procedures: * Sessions 1-2: Participants are connected to an EEG machine and familiarized with the hand orthosis (training device used in the study) and the tasks required for the study. * Sessions 3-4: Participants receive baseline transcranial magnetic stimulation (TMS) and fMRI. For TMS, a wire coil is held on the scalp. A brief electrical current is passed through the coil, creating a magnetic pulse that stimulates the brain. The subject may feel a pulling sensation on the skin under the coil and there may be twitching in muscles of the face, arm or leg. The subject may be asked to tense certain muscles slightly or perform other simple actions. The effect of TMS on the muscles is detected with small metal disk electrodes taped to the skin of the arms. fMRI is like a standard MRI (see above), except it is done while the patient performs tasks to learn about brain activity involved in those tasks. * Sessions 5-8: Participants are asked to repetitively move their hand (patients' paralyzed hand; healthy volunteers' normal hand), tongue and leg in response to three sound tones. After ten trials, they are asked to imagine the same movements 50 to 100 times while the EEG machine is recording brain activity. * Sessions 9-14: Participants are trained in controlling the hand orthosis. The subject's hand is attached to the orthosis and asked to imagine that they are performing finger or hand movements. This continues until there is an 80-90 percent success rate in achieving hand movement. * Sessions 15-16: Participants repeat TMS and fMRI for comparison before and after training with the hand orthosis. * Sessions 17-28: Participants receive additional training with the hand orthosis device (as in sessions 5-8), focusing only on the hand and not other parts of the body. * Sessions 29-30: Participants undergo repeat TMS and fMRI to compare with the effect following additional training with the hand orthosis. * Sessions 31-32: Optional makeup sessions if needed because of scheduling problems. Participants are evaluated in the clinic after 3 months to see if they have benefited from the study.
The purpose of this study is to determine if giving amphetamines along with standard rehabilitation speeds motor recovery after a stroke. In addition, if motor recovery is improved, the study will also identify the areas of the brain involved with the recovery. Researchers will use motor function ratings, PET scans, functional MRI (fMRI), electroencephalographs, and transcranial magnetic stimulation (TMS) to evaluate patients. Patients participating in the study will be placed in one of two groups; 1. Patients receiving dextroamphetamine and routine Rehabilitation Medicine 2. Patients receiving a placebo "sugar pill" and routine Rehabilitation Medicine Patients that have improved motor recovery will undergo neuroimaging and neurophysiological studies to identify areas of the brain involved.
The Hawks in Motion (HIM) High Intensity Exercise program is designed to implement the American Physical Therapy Clinical Practice Guidelines and American College of Sports Medicine recommendations for exercise for people with neurologic disability. Doctor of Physical Therapy (DPT) students administer the HIM High Intensity Exercise Program. A prior study evaluated the feasibility, safety, and efficacy of the HIM High Intensity Exercise Program and found it feasible, safe, and effective for 30 people with neurologic disabilities between the ages of 8-99 years. The investigators would like to evaluate whether participation in the HIM High Intensity Exercise Program affects mobility in everyday life. Physical activity will be measured one week before program implementation and one week after to assess if the participants' mobility in everyday improved.
This research study will combine non-invasive spinal stimulation with mobility devices to examine the acute impact of the individual and combined effects of these innovative techniques on mobility in children with cerebral palsy.
This study will investigate the clinical, functional and neurophysiological effects of automated mechanical peripheral stimulation (AMPS) via the Gondola device administered to patients with chronic stroke, cerebral palsy and Parkinson's Disease. Results will be collected using standardized outcome measures and a transcranial magnetic stimulation assessment protocol including electrical stimulation and electromyographic recording.
The study aims to develop a SmarToyGym where sensitized, wireless toys are strategically hung and placed within reach of infants to elicit toy-oriented body and arm/hand movements. Each toy will be equipped with sensors capable of measuring the infant's grasping actions such as squeezing, pinching, tilting, etc. A low-cost 3D motion capture system will be used to collect video data and the infants' reaching and body kinematics in response to the toys. A pressure mat will be used to measure postural changes to detect weight shifts, rolling, crawling and other movements away from the initial posture. By capitalizing on these wireless and low-cost technologies, it will permit the regular and non-invasive monitoring of infants, which can lead to detailed, non-obtrusive, quantitative evaluation of motor development. In this vein, the investigators also aim to conduct proof-of-concept testing of the SmarToyGym with atypical and typical developing infants. The investigators will include infants' ages 3 to 11 months who are categorized as high-risk or low-risk using the Bayley Infant Neurodevelopmental Screener.
