Tilt Table – A table which is used to gradually increase patients tolerance to being in a standing position. Also used to teach partial weight bearing and to give prolonged stretch in each position.
Tracheostomy – Opening in windpipe to facilitate breathing.
Upper Motor Neurons – Long nerve cells that originate in the brain and travel in tracts through the spinal cord. Any injury to these nerves cuts off contact with brain control. Reflex activity is still intact, however resulting in spasticity. For men with upper motor neuron injuries, reflex erections are possible.
Urinary Tract Infection (UTI) – Bacterial invasion of the urinary tract, which includes bladder, bladder neck and urethra. Symptoms of UTI include urine that is cloudy, contains sediment and smells foul, and fever. UTI involving the kidneys is preventable but dangerous. Medications often prescribed for UTI include Keflex, Macrodantin, Furadantin, Septra, Bactim, Mandelamine, penicillin, and amoxicillin. Side effects vary, and may include nausea and vomiting, skin rash or hives.
Ventilator – Mechanical device to facilitate breathing in persons with impaired diaphragm function.
Vertebrae – The bones that make up the spinal column.
Vital Capacity – The measure of air in a full breath. It is an important consideration for people with high-level tetraplegia who also have impaired pulmonary function.
Vital Signs – Consist of taking blood pressure, pulse, respiration and temperature.
Weaning – Gradual removal of mechanical ventilation, as patient’s lung strength and vital capacity increases.
Zone of Partial Preservation – Refers to those dermatomes and myotomes below the neurological level that remain partially innervated. When some impaired sensory and/or motor function is found below the lowest normal segment, the exact number of segments so affected make up the ZPP. The term is used only with incomplete injuries.
