This affection requires treatment variously, as it depends on one or
another procuring cause.
If it be the result of recent "cold," inducing acute catarrhal
irritation in the larynx, treat _first_ as for _common cold_, and
_close_ the sitting as follows: Place N. P., _long cord_, of A D
current, in good medium force, upon back of neck or in the mouth, and
treat three to five minutes, twice a day, with P. P., over the front
parts of the air pipe in the neck; mostly over the _larynx_--Adam's
apple.
If it be from paralysis of the larynx, treat with B D current, rather
strong force; placing P. P., _long cord_, on back of neck or in the
mouth, and work with N. P. over the _larynx_, and somewhat over the air
tube of the neck generally. Treat three to five minutes, daily.
If, as is sometimes the case, the difficulty proceeds from a relaxation
of the diaphragm, with general sagging down of the thoracic and
abdominal viscera, so as to draw upon the trachea, then treat the whole
trunk tonically, using the B D current. Place the N. P. low on back of
neck, and treat with P. P. over the abdomen and thorax, and especially
all around the edge of the diaphragm--along the lower line of the false
ribs. Treat with medium strength of current, ten minutes, three times a
week. The aim is to contract all the relaxed parts, so to relieve the
larynx from the strain upon it.
