For the patients with orthostatic hypotension or prolonged bed ridden cases, if we use tilt table to make them come in standing position, BP should be taken every 5 mins or all the time? Also, will the same method be applied for multiple sclerosis patients on tilt table? I’m kind of confused but had come across a question like this before.

The tilt-table test (also called a passive head-up tilt test or head upright tilt test) is a simple, inexpensive and informative test that can help identify the causes of fainting. The tilt table test involves placing a patient on a table with a foot-support, then tilting the table upward. The tilt-table may start off in a horizontal position and be tilted by degrees to a completely vertical position. The patient’s blood pressure, pulse and symptoms are monitored throughout the test. Some sources indicate monitoring on a minute-by-minute basis. The tilt-table test is designed to detect one of the most common causes of fainting or lightheadedness, a phenomenon known as postural hypotension (or orthostatic hypotension). Tilt-table testing may be done when heart disease is not suspected of being responsible for an attack of fainting (syncope) or near-syncope. Ref 1 

Multiple sclerosis (MS) is a nervous system disease that affects the brain and spinal cord. It damages the myelin sheath, the material that surrounds and protects the nerve cells. Symptoms of MS can include visual disturbances, muscle weakness, trouble with coordination and balance, sensations such as numbness, prickling, or ‘pins and needles’ and memory problems. There is no single test that is adequate to diagnose MS by itself. MS is diagnosed by utilising a combination of the patient’s medical history, physical exam, neurological exam, MRI, and other tests (such as cerebrospinal fluid test and evoked potential test) as well as the tilt table test to diagnose it.
