Seasickness Jump Test

[WVMike]

A friend told me a doctor did a jump test on him years ago to check for susceptibility to seasickness. It had to do with jumping up and down and how the eyes reacted to the jumping. He could not remember how it worked.

Does anyone know this test and how it works?

Not familiar with any technique called the jumping test, but there are various procedures involving movement of the head while the eyes remain fixated on a target that have been experimented with as gauges of susceptibility to seasickness. Results to date have been modest to the best of my knowledge, and the gadgetry involved is not applicable to the routine doctor's office setting.

Best regards.

Doc, thanks again, I have noticed that some folks are very prone to seasickness the slightest rocking sets them off while others do seem to be affected at all. My friend who told me about this test was a Navy Diver who was very prone and it was a Navy Doctor that did this test on him, this was many years ago. He got out of the Navy because of seasickness and joined the Army and started jumping out of airplanes with no problem! He told me the roughness or choppyness of water is no problem, but as soon as the boat starts to rock side to side, look out.

Indeed there are great individual differences in susceptibility to mal de mer.

Acceleration in a direction perpendicular to the longitudinal axis of the body, most notably vertical oscillatory motion at a frequency of 0.2 Hertz, is most likely to cause motion sickness. The incidence of motion sickness falls quite rapidly at higher frequencies. In short, it's slow the rolling that does in most folks.

Best regards.
