Neuromodulation of Blood Pressure Using Transcutaneous Spinal Stimulation in Chronic Spinal Cord Injury
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.

Insulin Resistance and Microvascular Blood Flow in Spinal Cord Injury
Persons with spinal cord injury (SCI) are at an increased risk for metabolic disorders, including that of insulin resistance. As a result of neurological injury, they often have impaired mechanisms that regulate blood vessel function below the level of injury. Insulin, which facilitates the transport of glucose into muscle cells, is also capable of regulating skin blood flow, with insulin resistance reducing perfusion. Although beyond the scope of this proposal, the possibility exists that impaired microvascular skin blood flow responses due to insulin may further predispose to ischemia of the skin at pressure points of bony prominence. This perturbed cutaneous vascular response may place persons with SCI at risk for the development and poor healing of pressure ulcers due to microvascular dysfunction secondary to neurologic and metabolic disorders. Primary Aim: To determine the association between systemic insulin sensitivity and insulin-mediated vasodilatation below the neurological level of injury. We hypothesize that individuals with systemic insulin sensitivity compared to those with insulin resistance will have greater insulin-mediated vasodilatation and an associated proportional increase in cutaneous blood perfusion. Thus, intact and appropriate endothelial-mediated regulation by insulin will be operative despite sub-lesional neurological impairment in insulin sensitive individuals with SCI. However, because of the absence of the SNS-mediated insulin action on the microvasculature (i.e., insulin-mediated sympathetic withdrawal), it is being hypothesized that the vasodilatory response to iontophoresis with insulin in insulin sensitive subjects with SCI will be less than that observed in neurologically intact controls with insulin sensitivity. Secondary Aim: To compare peak microvascular perfusion responses to endothelial-dependent vasodilatation by iontophoresis with acetylcholine to insulin. We hypothesize that the peak blood perfusion responses to iontophoresis with insulin will be comparable in magnitude to that of acetylcholine in individuals with greater systemic insulin sensitivity. This will be in contrast to individuals with systemic insulin resistance who will demonstrate a diminished response to iontophoresis with insulin when compared to that of acetylcholine. Because of SNS impairment, the peak vasodilatory response observed to these interventions will be lower in the group with SCI.

Effect of Aerobic Exercise Training on the Blood Biochemical Factors and Peripheral Hemodynamics in Person With Spinal Cord Injury
Background: Patients with spinal cord injury (SCI) have a higher prevalence of cardiovascular diseases compared to the healthy population. Aerobic exercise training is one of the recommended treatments. However, literature regarding the effect of aerobic training on patients with SCI is scarce. This study evaluated changes in parameters of exercise physiology and serum myokines immediately after exercise and after a training program among patients with SCI. Method: Male patients with SCI and age- and sex-matched healthy individuals were recruited. Cardio-pulmonary exercise testing (CPET) was used to determine oxygen uptake at peak exercise and anaerobic threshold in both groups. The patients with SCI attended aerobic exercise training for 36 sessions within 12-16 weeks. Basic data, hemodynamic and exercise physiology parameters, and serum myokine (myostatin, insulin like growth factor, and follistatin) concentrations were measured pre- and post-exercise in both groups, and were repeated in patients with SCI post-training.

Respiratory Motor Control and Blood Pressure Regulation After Spinal Cord Injury
The proposed study is designed to answer a novel research question: Can resistive respiratory muscle training designed to improve respiratory motor control also improve blood pressure regulation impaired by spinal cord injury? Resistive breathing exercise, or respiratory muscle training, has been applied to rehabilitate breathing after spinal cord injury, but has not been evaluated as a method for increasing resting blood pressure and / or improving its regulation under stress as is planned in the proposed project. For the first time, respiratory muscle training intervention will be used as a tool to investigate the physiological relationships between pulmonary and cardiovascular function in individuals with Spinal Cord Injury (SCI). Thus, it will foster a new direction from which to address neglected issues surrounding the cardiovascular complications of spinal cord injury.

Safety, Feasibility, and Efficacy of Transcutaneous Spinal Cord Stimulation on Stabilizing Blood Pressure for Acute Inpatients With Spinal Cord Injury
Current forms of pharmacologic and non-pharmacologic treatments for hypotension and orthostatic hypotension (OH) remain inadequate during acute inpatient rehabilitation (AIR) following a traumatic spinal cord injury (SCI). A critical need exists for the identification of safe, practical, and effective treatment options that stabilize blood pressure (BP) after traumatic SCI. Recent published evidence suggests that transcutaneous Spinal Cord Stimulation (TSCS) can be used to raise seated BP, and mitigate the falls in BP during orthostatic repositioning in individuals with chronic SCI. This site-specific project will focus on the use of TSCS to stabilizing seated BP and mitigate the fall in BP during orthostatic repositioning during AIR following traumatic SCI.

Safety, Feasibility, and Efficacy of Transcutaneous Spinal Cord Stimulation on Stabilizing Blood Pressure for Acute Inpatients With Spinal Cord Injury
This project will focus on a novel approach to stabilizing blood pressure (BP) during inpatient rehabilitation after acute SCI. After SCI, people have unstable blood pressure, ranging from too low (orthostatic hypotension) to too high (autonomic dysreflexia). Unstable BP often interferes with performing effective physical rehabilitation after SCI. A critical need exists for the identification of safe, practical and effective treatment options that stabilize BP after traumatic SCI. Transcutaneous Spinal Cord Stimulation (TSCS) has several advantages over pharmacological approaches: (1) does not exacerbate polypharmacy, (2) can be activated/deactivated rapidly, and (3) can be applied in synergy with physical exercise. The study team is asking the key question: "What if applying TSCS earlier after injury could prevent the development of BP instability?" To facilitate adoption of TSCS for widespread clinical use, the study team plans to map and develop a parameter configuration that will result in an easy to follow algorithm to maximize individual benefits, while minimizing the burden on healthcare professionals. This project will provide the foundational evidence to support the feasible and safe application of TSCS in the newly injured population, thereby overcoming barriers to engagement in prescribed inpatient rehabilitation regimens that are imposed by BP instability.
