[Dr. Zamboni] is conducting a new round of tests in which subjects will wear a collar fitted with a strain gauge to measure neck volume differences in the upright and prone positions. This will allow him to measure the time it takes for for blood to drain through the neck in MS vs. control subjects. This technique is called plethysmography and is less operator-dependent than Doppler ultrasound.
