Abstract
With 48 healthy university students, male and female, as subjects, using a stretcher to which a velocimeter, accelerometer and body pressure distribution meter were attached, the velocity was set to 3 km/h, 5 km/h and 7 km/h, and following a fixed route, transportation was carried out, and during course changes, the extent of acceleration and shift in the center of gravity were measured. The results were that during course changes in stretcher transportation, when the velocity was high, the acceleration was also high, in both forward-backward and left-right directions, and accompanying that, the distance of the shift in the center of gravity was also large. Additionally, a positive correlation was observed in acceleration and distance of the shift in the center of gravity at all velocities, in both forward-backward and left-right directions. Accompanying an increase in velocity, from the fact that the head undergoes significant movement, it is indicated that there is a necessity, while transporting, of keeping in mind the possibility that the condition of patients with head trauma or cervical spine injury may be negatively affected.
