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.

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.

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.

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.

Characterization of the Sleep-Wake Cycle in Traumatic Brain Injury Patients with a Disorder of Consciousness

Each year in France, 160,000 peoples suffer from a mild or severe traumatic brain injury (TBI). Sleep plays a crucial role in the process of brain plasticity, which is essential for neurological and cognitive recovery. However, the sleep-wake cycle is rarely, if ever, evaluated in patients with TBI and consciousness disorders within Post-Resuscitation Rehabilitation Units (SRPR). Caregivers develop, on a daily basis, an intuitive understanding of the patient's overall condition. This expertise deserves to be validated using objective sleep assessment tools (actigraphy). If proven accurate, it could lead to the implementation of a sleep-wake cycle evaluation protocol within SRPRs.
