Aegineta Paulus, The seven books of Paulus Ægineta… (1844)
“ A young man taller than the patient, or standing on some elevated object, by his affected side, (the patient also being in a standing posture) is to apply his shoulder below the patient’s armpit, while he stretches and pulls the patient’s hand towards his own belly, so that the rest of the patient’s body is suspended at the back of the person who supports him. But if the patient be light, another light child is to be suspended from him. For while the arm and the rest of the body are pulled downwards oppositely, the shoulder put under the armpit, readily replaces the dislocated limb. ”
