Patient intake

Enter clinical measurements below to run an in silico tilt-table simulation. All fields marked required must be completed before running.

Demographics

Beighton hypermobility score

Score from 0–9 if you already know it, or take the quick guided check below.

The Beighton score measures generalized joint hypermobility, which includes things like double-jointed fingers, elbows or knees that bend backward, or being able to place your palms flat on the floor without bending your knees. Hypermobility directly affects how your body circulates blood when you stand up, which is why this score is essential for the accuracy of your simulation. If you don't know your score, tap "I don't know my score" for 9 simple yes/no questions. It only takes a minute.

If you have recent orthostatic vitals from the last 3–5 days, use the reading that best represents how your body typically responds when you stand. If you have never done this before or don't have recent readings, here is how: lie down for 5 minutes, then take your blood pressure and heart rate while still lying down. Stand up and take another reading upright. Do not sit in between. If your symptoms tend to get worse the longer you stand, try standing for 2 to 10 minutes before taking your upright reading. If you take medications that affect heart rate or blood pressure such as beta blockers, this may affect accuracy.

Supine vitals

Measured while lying flat.

Standing vitals

Measured while upright.
