Self-control of psychophysiologic response to motion stress: using biofeedback to treat airsickness

Investigators of the Neuropsychiatry Branch, Clinical Sciences Division, U.S. Air Force School of Aerospace Medicine (USAFSAM), provided biofeedback-moderated behavioral treatment to 53 fliers grounded for chronic, severe motion sickness, and followed each flier for 2 years after treatment completion. Success was defined as returning to and maintaining satisfactory operational flying status. Of these, 42 fliers (79%) met this criterion; 3 (6%) were partially successful, and 8 (15%) were subsequently grounded for recurrent airsickness. Follow-on studies will investigate psychophysiological mechanisms through which this method of treatment works.
