Document Summary

Touch physiology: another thing you can do to fool the brain into thinking that a missing limb is still there is to use prosthesis, which is connected to the stump and converts muscular activity into movement. Patients who have a prosthesis like this rarely report experiencing phantom limb pain. No patients using myoelectric prosthesis reported feeling any pain, whereas those (cid:449)ho (cid:449)e(cid:396)e(cid:374)(cid:859)t usi(cid:374)g a p(cid:396)osthesis te(cid:374)ded to (cid:396)epo(cid:396)t so(cid:373)e deg(cid:396)ee of pai(cid:374). Study: they looked at the brain representation of the face area. Remember: the idea is that the more the face representation moves up, the higher the chance one will experience phantom limb pain. Here, we have the brains of: (1) a control group, (2) patients with prosthesis, and (3) patients without prosthesis. The idea was to check if the (cid:396)ep(cid:396)ese(cid:374)tatio(cid:374) of the fa(cid:272)e (cid:449)as s(cid:455)(cid:373)(cid:373)et(cid:396)i(cid:272) i(cid:374) (cid:271)oth he(cid:373)isphe(cid:396)es.
