These, in the hands of a clever operator who knows his
anatomy well, are therefore, on the whole, more satisfactory, but they
require some experience to manage them so as not to shock and disgust
the patient by inflicting needless pain. The poles, covered with
absorbent cotton well wetted with salt water, which may be readily
changed, so as not to use the same material more than once, are placed
on each muscle in turn, and kept about four inches apart. They are moved
fast enough to allow of the muscles being well contracted, which is
easily managed, and with sufficient speed, if the assistant be
thoroughly acquainted with the points of Ziemssen. The smaller electrode
should cover the motor-point and the larger be used upon an indifferent
area. After the legs are treated, the muscles of the belly and back and
loins are gone over systematically, and finally those of the chest and
arms. The face and neck are neglected. About forty minutes to an hour
are needed; but at first a less time is employed. The general result is
to exercise in turn all the external muscles.
