While travelling in a vehicle compared to semi-supine or seated postures persons may be affected more in the supine posture by the vibrations transmitted to their bodies. Patients are exposed to significantly high levels of whole-body vibrations during their transportations in an ambulance. High velocities cause high magnitude forces that pose high physiological dynamic hazards [1]. These result in discomfort and cause adverse affects on patients. The slope of the upper part of the stretcher affects the body posture which in turn alters the body’s response to vibration [2]. Studies show that the presence of backrest increases the resonance frequency of the body [3]. The condition of the road surface or the road type and the speed of the vehicle may further worsen the patient’s situation.
