When a person’s muscles are completely relaxed, the weight of the whole body is unevenly distributed over a wide range. If people are lifted in waking state, they will tighten their muscles, tighten their limbs, or ring their arms around each other’s neck.
At this time, the burden on the other party will be relatively small, because the center of gravity is concentrated in the center. However, the comatose person is weak, so the limbs will sway at will, causing the center of gravity to shift irregularly.
However, if you use the “firefighter shoulder method”, you can firmly grasp the unconscious person and control the weight distribution.
