Development and Test of a Headset for BCI Until Obtaining an Efficient and Comfortable System That Can be Used in Daily Practice by ALS People

"Brain-computer interfaces (BCIs) are computer-based systems that acquire brain signals, analyze them, and translate them into commands that are relayed to an output device to carry out a desired action. BCIs represent a very active and promising field of research among devices for people with severe motor disabilities. As the currently available systems correspond to research prototypes, they are not adapted to daily live situations. On the other hand, some systems have recently been commercialized, principally for video games but they are not satisfactory for use as a substitute technology in disability. A BCI's prototype for alternative communication using a virtual keyboard, the P300 Speller, has been developed by the National Institute for Research in Digital Science and Technology (Athena team - Nice University). This prototype includes an EEG-cap with gel based active electrodes. A recent study conducted on 20 patients with ALS (University Hospital, Nice) demonstrated the usability of the system and the patient satisfaction concerning the ease of use and utility. To achieve a system that can be used in daily live in severely disabled patients, technical developments are necessary. The investigators have conceptualized and developed an ergonomic, comfortable, headset, including dry electrodes to allow a prolonged use of the system. The purpose of the study conducted all along the development of the headset is to improve the developed system until a successful system is achieved. This study is a monocentric usability study conducted on ALS people.

Multi-speed Ergonomic Wheelchair

Over one million Americans rely on their upper extremities for manual wheelchair propulsion. Shoulder overuse injuries are prevalent among manual wheelchair users and these injuries often result in shoulder pain. Severe shoulder pain can lead some wheelchair users to transition from manual to powered mobility, complicating transportation, and reducing independence in activities of daily living. This project will expand the understanding of a new wheelchair design that allows better positioning of the hand rims and allows for different gearing. The investigators will study steady-state propulsion efficiency with different gear ratios and develop a new system with multiple gear ratios. The advanced gearing will allow for a low gear when initiating movement, going uphill, or when moving over carpet, and then a higher gear option for movements on hard flat level terrain. This system has the potential to dramatically improve shoulder ergonomics and reduce pain in many future manual wheelchair users.

Spinal Cord Transcutaneous Stimulation Effect on Blood Pressure in Acute Spinal Cord Injury (SCI)

The goal of this clinical trial is to evaluate the effect of transcutaneous spinal cord stimulation on blood pressure in individuals with an acute spinal cord injury (within 30 days of injury). Blood pressure instability, specifically orthostatic hypotension (a drop in blood pressure when moving lying flat on your back to an upright position), appears early after the injury and often significantly interferes with participation in the critical rehabilitation time period. The main questions it aims to answer are: 1. Can optimal spinal stimulation increase blood pressure and resolve orthostatic symptoms (such as dizziness and nausea) when individuals undergo an orthostatic provocation (a sit-up test)? Optimal stimulation and sham stimulation (which is similar to a placebo treatment) will be compared. 2. What are the various spinal sites and stimulation parameters that can be used to increase and stabilize blood pressure to the normal range of 110-120 mmHg? Participants will undergo orthostatic tests (lying on a bed that starts out flat and then moved into an upright seated position by raising the head of bed by 90° and dropping the base of the bed by 90° from the knee) with optimal and sham stimulation, and their blood pressure measurements will be evaluated and compared.

The Effect of Transcutaneous Stimulation on Blood Pressure in Spinal Cord Injury (SCI)

This project will investigate the effect of spinal cord transcutaneous stimulation on blood pressure in individuals with a chronic spinal cord injury who experience blood pressure instability, specifically, orthostatic hypotension (a drop in blood pressure when moving from lying flat on your back to an upright position). The main questions it aims to answer are: 1. What are the various spinal sites and stimulation parameters that normalize and stabilize blood pressure during an orthostatic provocation (70 degrees tilt)? 2. Does training, i.e., exposure to repeated stimulation sessions, have an effect on blood pressure stability? Participants will undergo orthostatic tests (lying on a table that starts out flat, then tilts upward up to 70 degrees), with and without stimulation, and changes in their blood pressure will be evaluated.

Effects of Long Term Ventilation Support on the Quality of Life of ALS Patients and Their Families

Amyotrophic lateral sclerosis (ALS) is a serious rapidly progressive disease of the nervous system. The average survival from the time of diagnosis is two to three years. The patient physical and psychological sufferings in ALS are immense, and apart from Riluzole, there is no effective treatment. Care of advanced ALS have an estimated cost of 4-8 million NOK per year. Perhaps the most challenging topic of ALS care is the decision to extend ventilation support into the stages of disease that require treatment both during day and night. In these cases, treatment is clearly life-sustaining and although quality of life may be maintained, the burden of caregiving imposed upon family or health care workers is huge, regardless of tracheostomy (TIV) or non-invasive (NIV) modality. The present study is a longitudinal questionnaire study in Norway measuring overall quality of life, health-related quality of life, and disease-specific quality of life in ALS patients, partners and children before and after the introduction of life sustaining ventilation support. The investigators aim to increase the knowledge on how life-sustaining ventilation support with NIV or TIV affects the quality of life in ALS patients, life partners and children. The results from the study may provide crucial information for clinicians and patients on one of the most difficult ethical issues of ALS treatment. The investigators anticipate that this information will facilitate a shared decision making processes, weighing benefits and disadvantages in a wider perspective.

Optimization of Adaptive Rowing Seating

Adaptive sports programs are integral components to combating Veteran isolation, promoting wellbeing and seeking to build teams, networks, communities. These activity-based communities are medicine free treatment systems enhancing Veterans' health from a holistic perspective. This approach to Veteran healthcare is critical as studies indicate Veterans not only have 56% higher perceived social isolation but are also 1.5x more susceptible to suicide than the general public. It is imperative to improve access to exercise and physical activity through adaptive sport or recreation. This proposal is going to focus on Adaptive Indoor Rowing for Veterans with limited or changing trunk stability (i.e. SCI/D, paralysis, paresis, etc.). Rowing is a unique full-body activity that increases cardiovascular demand and increases coordination and aerobic capacity through movement. This proposal aims to address critical gaps in adaptive rowing technology and provide Veterans with limited trunk stability access to full stroke adaptive rowing.

Targeted HD-tDCS to Improve Upper Limb Rehabilitation in SCI

The proposed project seeks to maximize the functional recovery achieved during the rehabilitation of the paretic upper limbs in individuals with SCI. The investigation will work towards optimizing the use of transcranial direct current stimulation (tDCS), an adjunct known to improve the effectiveness of rehabilitation. In particular, the relationship between the specificity of current delivery and functional benefit will be explored, and findings may lead to a framework that can be translated to the clinic setting.

Laser Interstitial Thermal Ablation and Stereotactic Radiosurgery for Patients With Spine Metastases

The purpose of this research is to combine two complementary modes of treatment, spinal interstitial laser ablation and stereotactic spine radiosurgery (SSRS) for the treatment for spinal tumors near the spinal cord with an objective to improve tumor control, improve pain control, preserve function, and improve quality of life. We will also assess how effective these combined modes of treatment are in patients with spinal metastasis with an epidural component.

Prophylactic Pregabalin Treatment Following Spinal Cord Injury

Patients arriving to rehabilitation up to 3 months following SCI will be given (study group) or not (control group) Lyrica (75X2). They will be followed for central pain development.

Locomotor Training With Testosterone to Promote Bone and Muscle Health After Spinal Cord Injury

This pilot study will determine the feasibility of implementing a combinatory rehabilitation strategy involving testosterone replacement therapy (TRT) with locomotor training (LT; walking on a treadmill with assistance and overground walking) in men with testosterone deficiency and walking dysfunction after incomplete or complete spinal cord injury. The investigators hypothesize that LT+TRT treatment will improve muscle size and bone mineral density in men with low T and ambulatory dysfunction after incomplete or complete SCI, along with muscle fundtion and walking recovery in men with T low and ambulatory dysfunction ater incomplete SCI.

Wearable Electrical Stimulation on the Back to Modulate Spinal Cord Activity

The goal of this study is to evaluate if non-invasive electrical spinal stimulation can help people with paralysis caused by SCI improve strength and function of their arms, legs, hands or feet. The study will involve therapy sessions involving exercises done at the same time as electrical stimulation therapy. This study has multiple parts to evaluate the effectiveness and safety of "smart" electrical stimulation of the spinal cord, which involves stimulating the spinal cord at precise locations and times to improve movement and function.

Use of TDCS Stimulation in Neurological and Gynaecological Conditions

The aim of the study is to test the effect of tDCS stimulation on upper and lower limb function in neurological patients and to reduce pain in gynaecological patients. And the impact of tDCS stimulation on patients' quality of life. Standardised questionnaires will be used for pre- and post-stimulation evaluation.

NG004 in Spinal Cord Injury Patients

This is the FIH, multicenter, open-label, sequential, multiple ascending dose trial of NG004 in patients with acute incomplete cervical SCI. The trial will evaluate the safety, tolerability, and PK of 4 dose regimens of NG004, and will evaluate the maximum tolerated dose of NG004.

Stem Cell Spinal Cord Injury Exoskeleton and Virtual Reality Treatment Study

The SciExVR study will evaluate the potential benefit of autologous bone marrow derived stem cells (BMSC) in the treatment of spinal cord injury with evidence of impaired motor or sensory function. The treatment consists of bilateral paraspinal injections of the BMSC at the level of the injury as well as superior and inferior to that spinal segment followed by an intravenous injection and intranasal placement. Patients undergoing BMSC treatment may also be assigned to use of exoskeletal movement (or equivalent) or virtual reality visualization (or equivalent) to augment upper motor neuron firing and/or receptivity of the sensory neurons. http://mdstemcells.com/sciexvr/

Interventional Cooperative Agreement Program - Vocational Intervention Demonstration

For many people with spinal cord injury or brain injury, seeking employment after injury is an important goal. There are services available to help people with disabilities. However, the best ways to coordinate and deliver these services are not yet known. This project will compare two ways of coordinating and delivering services that are designed to help people with spinal cord injury or brain injury obtain employment.

Early Intervention to Promote Return to Work for People With Spinal Cord Injury

However, the best ways to coordinate and deliver these services are not yet known. This project will compare two ways of coordinating and delivering services that are designed to help people with spinal cord injury obtain employment.

Regeneration in Cervical Degenerative Myelopathy

Degenerative (wear and tear arthritis of the spine) Cervical (concerning the neck) Myelopathy (injury to the spinal cord), DCM, is the most common spinal cord disorder of adulthood. In DCM, arthritis of the spine causes compression of the spinal cord. The symptoms of DCM are often mistaken for natural consequences of ageing, including numb and clumsy hands, loss of coordination, imbalance, bladder and bowel problems. The weakness can progress to severe paralysis. Every year approximately 4 individuals in 100,000 undergo surgery for DCM; however, many more individuals are thought to suffer from DCM. The main treatment for DCM is surgery. The aim of surgery is to create space and remove the compression of the spinal cord. This is known to prevent further injury. Unfortunately, the post-operative improvements are often incomplete and many patients remain severely disabled. Improving outcome after surgery represents an important unmet clinical need. Clinical and preclinical findings indicate that the drug Ibudilast can stimulate neuroprotective and regenerative processes in the spinal cord. Ibudilast is well-tolerated and used to treat asthma and post-stroke dizziness in Japan and is currently being investigated for use in treating other neurological diseases. This study will investigate whether daily oral administration of Ibudilast for a maximum of 34 weeks can improve hand function, strength, balance, urinary problems and reduce pain. The study will initially be conducted at three sites in the UK, with more sites added as necessary. Individuals between 18-80 years old, diagnosed with DCM and scheduled for an operation for the first time will be invited to participate in the trial. The study will entail patient questionnaires and clinical assessments before surgery, shortly after surgery and 3, 6, and 12 months after surgery. Moreover, patients will undergo MRI scans pre-operatively and at 6-months postoperatively to determine whether the treatment was successful.
