Electricity : its medical and surgical applications, including radiotherapy and phototherapy . ren, at the junction of the upperand middle thirds, directly outside the point for the tibialis anticus. Extensor Proprius Pollicis.—Close to the outer edge of the crest ofthe tibia, a variable distance (two to four finger-breadths) above theankle.

While the points indicated in the diagrams are correct for mostindividuals, anatomical peculiarities may exist in others which causethe motor point to be in a different location from that indicated. Itis therefore well in all cases to move the electrode to other points inthe vicinity of the supposed motor point to determine if it really is themost irritable place. If it is not, a current strength which will givea minimal contraction when the electrode is there placed, will give astronger one when the more irritable location is stimulated, and thiswould be the motor point in this particular case.
