Development and Test of a Headset for BCI Until Obtaining an Efficient and Comfortable System That...
Amyotrophic Lateral SclerosisMotor Neuron Disease5 more"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.
Early Intervention to Promote Return to Work for People With Spinal Cord Injury
Spinal Cord InjuriesSpinal Cord DiseasesFor many people with spinal cord 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 obtain employment.
Wearable Electrical Stimulation on the Back to Modulate Spinal Cord Activity
Spinal Cord InjuriesSpinal Cord DiseasesThe 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.
CEUS For Intraoperative Spinal Cord Injury
Spine DiseaseSpinal Stenosis5 moreSpinal cord injury following posterior decompression in patients suffering from chronic, cervicothoracic spinal cord compression is a known complication with multiple etiologies. Currently, intraoperative neuromonitoring (IONM) remains the gold standard for predicting and preventing post-operative deficits from these procedures. However, there is a paucity in the field of spine surgery for further, non-invasive biomarkers that can help detect and prognosticate the degree of spinal cord injury intraoperatively. Contrast enhanced ultrasound (CEUS) is a radiation free imaging modality that utilizes nanobubble technology to allow for visualization of the macro- and microvascular architecture of soft tissue structures. Despite being currently approved for the use in hepatology and cardiology, it has remained absent from the field of spinal cord injury. The study team aims to evaluate and quantify micro- and macrovascular changes that lead to areas of hyper-perfusion as well as areas of ischemia intraoperatively in patients that undergo elective cervicothoracic posterior decompression for chronic compression. In addition, the study team aims to assess the efficacy of CEUS in detecting microvascular changes that correlate with IONM changes and predicting degree and recovery of post-operative neurologic deficits from intraoperative spinal cord injury. The study team hypothesizes that following decompression, subjects will have detectable levels of microvascular changes causing areas of hypoperfusion and reperfusion injury. Second, the study team hypothesizes that these perfusion changes will correlate with intraoperative neuromonitoring changes and can predict and prognosticate the degree of post-operative neurologic injury.
Posterior Cervical Fixation Study
Degenerative Disc DiseaseCraniocervical Injuries7 moreThe objective of this study is to evaluate the safety and performance of occipito-cervico-thoracic spine surgery using posterior fixation as measured by reported complications, radiographic outcomes, and patients reported outcomes (PROs).This study is being undertaken to identify possible residual risks and to clarify mid-to long-term clinical performance that may affect the benefit/risk ratio of posterior fixation systems.
NuVasive® ACP System Study

Proprioceptive Deficits in Degenerative Cervical Myelopathy
Cervical MyelopathyProprioceptive deficits in degenerative cervical myelopathy (DCM) is a progressive neurological deficits in somatosensory and motor function which affects the body balance and motor control. DCM usually presents with body incoordination, hand clumsiness and gait disturbance associated with proprioceptive dysfunction that hinders the physical performance and functions. In this study, a non-invasive assessment protocol on proprioception will be developed for detecting subtle proprioceptive deficits at the early stage of disease through simple Physical Performance Tests for population older than 45. By adopting the physical performance tests as the diagnostic predictors of DCM, we aim to avoid the development of devastating consequences and disabilities.

Degenerative Cervical Myelopathy Repository
Cervical MyelopathyTo create a research repository of patients with known degenerative cervical myelopathy (DCM) and a control cohort of subjects who have non-myelopathic spinal disease. This repository will be used to assess functional and/or biological measures that may allow for improved prediction of symptomatic progression and response to treatment in patients with DCM. In addition, this repository will be used to develop a risk assessment scale to accurately predict functional outcomes following operative management of DCM.
