A<unk><unk>  is used to bring a patient in a vegetative state to an upright position. (This video is meant to illustrate the<unk>  and its operation, not the test.) A<unk>  <unk> , occasionally called upright<unk>  testing (UTT), is a medical procedure often used to diagnose dysautonomia or syncope. Patients with symptoms of dizziness or lightheadedness, with or without a loss of consciousness (fainting), suspected to be associated with a drop in blood pressure or positional tachycardia are good candidates for this test. The procedure tests for causes of syncope by attempting to cause syncope by having the patient lie flat on a special<unk>  or bed and then be monitored with ECG and a blood pressure monitor that measure continuous, beat to beat, non-invasively. The<unk>  then creates a change in posture from lying to standing.
