Spinal stimulation may restore cough power after paralysis

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Currently admitted for inpatient rehabilitation at Shirley Ryan AbilityLab * History of traumatic spinal cord injury with Neurologic Level of Injury (NLI) C1-T1, and AIS A-C on admission exam * Between 14-60 days from date of injury at time of enrollment * Baseline PCF below 270 L/min * Anatomical airway or tolerating occlusion of tracheostomy with either a one-way speaking valve or a cap for at least 60 minutes * Medically cleared by the participants primary inpatient physiatry attending physician Exclusion Criteria: * Individuals with pre-morbid chronic pulmonary conditions, day-time ventilator dependence, uncontrolled autonomic dysreflexia, moderate to severe traumatic brain injury, developmental delay, diagnosis of active cancer, or secondary progressive neurologic disorder * Individuals with contraindications to the interventions of interest: 1. TSCS and Abdominal FES: pacemaker, compromised skin integrity under site of stimulation, implanted defibrillators, deep brain stimulator(s), uncontrolled epilepsy or seizures, pregnancy, recent myocardial infarct, diaphragmatic pacer 2. TSCS: Severe osteoporosis 3. Abdominal FES: unhealed rib fracture, sternal precautions, recent pneumothorax, spine bracing impacting ability to place stimulation pads. * Individuals with medical instability impacting the safety and feasibility of participation including the inability to tolerate sitting upright \>45 degrees for 15 minutes, acute unresolved medical complications as determined by study physician to be exclusionary, transferred to higher level of medical care for ≥5 consecutive days or \>14 days total during trial period, and those with halo spine bracing * Individuals who are currently enrolled in another interventional research study are excluded from participating to eliminate potential influence of additional experimental interventions on study outcomes and to maintain standardization of study protocol
