Filter by:Injuries affecting the central nervous system may disrupt the cortical pathways to muscles causing loss of motor control. Nevertheless, the brain still exhibits sensorimotor rhythms (SMRs) during movement intents or motor imagery (MI), which is the mental rehearsal of the kinesthetics of a movement without actually performing it. Brain-computer interfaces (BCIs) can decode SMRs to control assistive devices and promote functional recovery. Despite rapid advancements in non-invasive BCI systems based on EEG, two persistent challenges remain: First, the instability of SMR patterns due to the non-stationarity of neural signals, which may significantly degrade BCI performance over days and hamper the effectiveness of BCI-based rehabilitation. Second, differentiating MI patterns corresponding to fine hand movements of the same limb is still difficult due to the low spatial resolution of EEG. To address the first challenge, subjects usually learn to elicit reliable SMR and improve BCI control through longitudinal training, so a fundamental question is how to accelerate subject training building upon the SMR neurophysiology. In this study, the investigators hypothesize that conditioning the brain with transcutaneous electrical spinal stimulation, which reportedly induces cortical inhibition, would constrain the neural dynamics and promote focal and strong SMR modulations in subsequent MI-based BCI training sessions - leading to accelerated BCI training. To address the second challenge, the investigators hypothesize that neuromuscular electrical stimulation (NMES) applied contingent to the voluntary activation of the primary motor cortex through MI can help differentiate patterns of activity associated with different hand movements of the same limb by consistently recruiting the separate neural pathways associated with each of the movements within a closed-loop BCI setup. The investigators study the neuroplastic changes associated with training with the two stimulation modalities.
This is a pilot study to identify biomarkers that individually, and in combination, demonstrate the greatest sensitivity to repetitive, low-level blast exposure (RLLBE) neurotrauma in Special Operations Forces (SOF) personnel. The proposed cross-sectional, multimodal study will elucidate the potential effects of long-term RLLBE by comparing biomarkers across subjects.
the study is designed to perform an intervention for enhancement of cerebral blood flow in patients with traumatic brain injury showing vasospasm through transcranial doppler
Both GLP-2 and GIP reduce bone resorption (measured as CTX) in healthy persons. In this study, we will investigate whether GLP-2 and GIP is reducing CTX in individuals with spinal cord injury.
Cardiovascular disease has become the leading cause of death in the spinal cord injury population. Increased reliance on the renin-angiotensin-aldosterone system (RAAS) is believed to decrease falls in blood pressure when moving from a laying down position to upright; however, findings in the general population link the RAAS with remodeling and restructuring of the arterial walls. Therefore, intervention to stabilize and normalize blood pressure should be a priority in individuals with spinal cord injury who have low blood pressure. Advances in stimulation on the skin of the spinal cord offer an approach to restore cardiovascular control and improve blood pressure regulation; however, electrode placement and stimulation parameters needed to increase blood pressure are not well understood. Therefore, the aim of the study is to identify placement of electrodes on the skin, and frequency and amplitude of the stimulation to regulate blood pressure.
To evaluate whether retrograde venous reperfusion of a renal graft before antegrade arterial reperfusion can reduce ischemic-reperfusion injury. All registered eligible candidates for kidney transplant will be randomized to receive either: - retrograde venous, then arterial reperfusion or - antegrade arterial reperfusion.
Severe Acquired Brain Injury (sABI) is defined as "an encephalic impairment that occurs after birth and is not related to a congenital or degenerative disease. This impairment may be temporary, or permanent, and cause partial or functional disability or psychosocial distress." In Italy there are at least 10-15 new cases of sABI per year per 100,000 inhabitants; the estimated prevalence is about 150,000 cases per year. Often, people with sABI present focal neurological deficits, including alterations in strength, sensitivity, coordination and gait. Most of the rehabilitation protocols for people with sABI are derived from post-stroke studies, caused by lack of evidence on specific rehabilitation of people with sABI. Rehabilitation of people with sABI should begin as soon as possible, to prevent the onset of retractions and decubitus, and to regain joint mobility, strength, and coordination. OMEGO® (Tyromotion) is a newly developed device used in lower extremity rehabilitation, that provides visual and auditory feedback. Specifically, OMEGO® contains several games developed to enhance and promote learning behaviors, that simulate activities of daily living. The use of devices such as cycle ergometers is recommended in the rehabilitation of people with sABI; however, there are no studies demonstrating the effect of cycle ergometer training in association with visual feedback. The purpose of this study is to evaluate, both in people without apparent pathology (hereafter identified as "healthy") and in people with sABI, whether visual feedback during OMEGO® exercise modifies brain connectivity, emotional drive, and lower limb performance during a lower limb-specific motor rehabilitation task.
The aim of the present randomized trial is to assess the efficacy of wound drains in terms of reducing the rates of surgical site infection in obese patients with gynecological cancer.
Respiratory motor control deficit is the leading cause of morbidity and mortality in patients with spinal cord injury. The long-term goal of this NIH-funded study is to develop a rehabilitation strategy for respiration in patients with spinal cord injury as a standard of care. Respiratory function in patients with chronic spinal cord injury can be improved by using inspiratory-expiratory pressure threshold respiratory training protocol. However, the effectiveness of this intervention is limited by the levels of functional capacity preserved below the neurological level of injury. Preliminary data obtained for this study demonstrate that electrical spinal cord stimulation applied epidurally at the lumbar level in combination with respiratory training can activate and re-organize spinal motor networks for respiration. This study is designed to investigate respiratory motor control-related responses to epidural spinal cord stimulation alone and in combination with respiratory training. By characterization of respiratory muscle activation patterns using surface electromyography in association with pulmonary functional and respiration-related cardiovascular measures, the investigators expect to determine the specific stimulation parameters needed to increase spinal excitability below level of injury to enhance responses to the input from supraspinal centers that remain after injury and to promote the neural plasticity driven by the respiratory training. This hypothesis will be tested by pursuing two Specific Aims: 1) Evaluate the acute effects of epidural spinal cord stimulation on respiratory functional and motor control properties; and 2) Evaluate the effectiveness of epidural spinal cord stimulation combined with respiratory training.
To fill up the research gaps and build up a healthcare service model for geriatric trauma patients, this two-stage study aims to (a) develop geriatric trauma Artificial Intelligence (AI) prediction models by comparing the outcomes from clinical assessment and AI joint images; and (b) examine the long-term effects of an innovative health service program in geriatric trauma patients.
