It is quite reasonable to suppose that in diseased nerves (1.e., those with diminished vitality) an even much briefer amount of continuous pressure applied daily at or about the same spot would be sufficient to further reduce their vitality. Moreover, any pressure, if not instantaneously removed, would cause venous and lymphatic stasis and temporary anemia in and around the nerve, and so would still further aid in reducing its function by impairing the nutrition. These considerations make it clear, however, why the old nerve pressures were actually employed for neuralgic and spasmodic affections of nerves, inasmuch as they diminished their excitability. Equally it explains why, as regards conditions of paralysis and anesthesia, they were useless in the great majority of cases, indeed, sometimes only making matters worse. It was during the latter part of the sixties that a new efficacious and rational method of direct manipulation of the nerve was evolved. Henrik Kellgren instinctively concluded that what was needed was a mechanical stimulation of nerve applied in such a manner that none of the detrimental results from continued pressure would arise; guided by this principle, he systematized a method of “ nerve fric- tion.”” At the same time he also elaborated various methods of nerve vibration. These manipulations have been employed by him and his pupils during the past forty years and more, and a large number of cases of facial ee have been a oe treated in this way. % Compt. rend.
