Upright magnetic resonance imaging, supine magnetic resonance imaging, CT scan, and flexion and extension x-rays may also be used but are far less accurate and have a much higher potential for false negatives. The measurements to diagnose craniocervical instability are: Clivo-Axial Angle equal or less than 135 degrees
Sitting in a good posture with a good ergonomic chair will help keep your neck in a good posture when adjusted appropriately. If you are sitting or standing in a poor posture overtime it can lead ...
Delayed onset Lhermitte's sign has been reported following head and/or neck trauma. [9] [10] This occurs ~2 1/2 months following injury, without associated neurological symptoms or pain, and typically resolves within 1 year. [citation needed]
Symptoms that are worse when sitting or standing and improve when lying down, including lightheadedness, vertigo, tinnitus, slurred speech, confusion, coathanger pain in neck and shoulders, grayed or blurred vision, severe fatigue, fainting or near fainting: Complications: Cumulative brain damage, sudden death from falls: Diagnostic method
The condition is characterised by a posture with vagi at the head sitting somewhat forward of the shoulders (i.e., the ear lobe is anterior to a vertical line through the point of the shoulder (acromion process)). This can be very marked, with the back of the skull positioned anterior to the breastbone (sternum).

POTS patients experience an increase in heart rate within a few minutes of standing or sitting up. This makes it different from other conditions that generally cause a fast heart rate.
The causes of this condition are not well understood, but research suggests that it may be caused by a combination of hemodynamic and neurohumoral factors. [8]Some studies have found that orthostatic hypertension may be caused by increased vascular resistance, possibly due to excess plasma shifts or increased blood viscosity.
