NO signs of: In medicine, Hoffmanns sign, named after the German physiologist, Paul Hoffmann[1][2][3][4] (1884–1962, physiologist in Freiburg) is a distal sign of nerve regeneration. Contents [hide] 1 Definition 2 History 3 References 4 See also Definition[edit] A Hoffmann (or Tinels sign) is a tingling sensation triggered by a mechanical stimulus in the distal part of an injured nerve. This sensation radiates peripherally, from the point where it is triggered to the cutaneous distribution of the nerve. The tingling response can be compared with that produced by a weak electric current, as in transcutaneous electrical nerve stimulation (TENS). This unpleasant sensation is not a severe pain and does not persist.[5] History[edit] In March 1915, Paul Hoffmann described the distal regeneration sign then baptised: Hoffmanns sign. In October 1915, Jules Tinel described the same phenomenon in French le signe de fourmillement: Tinels sign. In fact, the first to have described, in 1907, this phenomenon of sensory recovery were the British surgeons: Wilfred Trotter & H. Morriston Davies.[6][7] References[edit] Jump up ^ synd/3740 at Who Named It? Jump up ^ Hoffmann. P. Über eine Methode, den Erfolg einer Nervennaht zu beurteilen.
