Navy Medicine personnel deploy with Sailors and Marines worldwide, providing critical mission support aboard ship, in the air, under the sea and on the battlefield. By: Dr. Richard D.

Principal areas of investigation include spatial disorientation, situational Read our publications awareness, motion sickness, adaptation to unusual acceleration environments, effects of altitude, sustained operations and View our photo stream fatigue, personnel selection testing, and visual and auditory sciences. Watch our videos Our lab boasts a unique collection of man-rated acceleration research devices. These devices are used by NAMRU-Dayton researchers, as well as by visiting scientists from around the world. One of the devices is the Vertical Linear Accelerator Navy Medicine Live Archives (VLA). March 2015 (4) The Vertical Linear Accelerator is designed The VLA is designed to generate precisely controlled vertical February 2015 (16) to generate precisely accelerations and serves as a platform for human research on January 2015 (12) controlled vertical such problems as vibration, spatial disorientation and motion accelerations and sickness. Numerous studies have linked whole body vibration December 2014 (17) http://navymedicine.navylive.dodlive.mil/archives/1632[3/6/2015 12:00:10 PM] Naval Medical Research Unit-Dayton’s Vertical Linear Accelerator | Navy Medicine serves as a platform for exposure, such as that experienced by helicopter occupants, to November 2014 (11) human research on chronic neck and back pain, fatigue, discomfort, and even such problems as decreased situational awareness in the cockpit. Competing October 2014 (15) vibration, spatial visual and vestibular sensory information on moving platforms September 2014 (20) disorientation and can cause spatial disorientation or motion sickness. Mitigating August 2014 (14) motion sickness. vibration related neck and back pain, and understanding interactions between the visual and vestibular systems are July 2014 (13) critical for operational effectiveness. June 2014 (8) The VLA possesses a stainless steel monolithic column, which allows 12 feet of vertical travel May 2014 (11) distance. For vibration research, low amplitude oscillations on the order of 0.1 G can be April 2014 (9) produced at frequencies between 4-25 Hz, a physiologically relevant range, and a range mirrored by the blade passing frequency of airframes currently in the DoD inventory. For March 2014 (14) vestibular research on applications such as motion sickness, sinusoidal accelerations of up to February 2014 (7) +/- 1 G can be produced at frequencies between 0.1 – 2 Hz. Air bearings between the column January 2014 (7) and carriage reduce velocity dependent noise and vibrations, minimizing external cuing to the volunteer subject. A fully reconfigurable carriage provides great flexibility allowing for December 2013 (7) the integrating of up to 400 pounds of payload which can include volunteer subjects, November 2013 (12) alternative seating design, visual displays, or other equipment.
