NERVE VIBRATIONS. 73
and the consequences for the better were really remarkable.
In order to take the vibrations on their own merit, I gave
nothing else at the beginning. Not only did the pain
diminish and nearly disappear after my first treatment, but
the improvement was sustained; and where the patients had
been racked with pain day and night, they obtained rest and
could sleep.
In the popliteal space, at its upper part, the nerve divides
into the internal and external popliteal nerves.
The internal, passing as it does right through the popliteal
space, is easily felt, and there is little or no difficulty in applying
frictions to it. When it passes down into the calf as posterior
tibicd, and is covered by the large muscles of that region, we
must take care that these move with our fingers. Behind the
internal malleolus, it lies with the artery quite superficially,
between the tendons of the flexor longus digitorum and flexor
longus hallucis. Frictions over the nerve in this position give
the same tingling feeling as when the " funny bone " is struck.
By slightly stretching and inverting the foot, we can follow the
nerve to its division into internal and external plantar nerves,
where strong frictions produce marked pain.
The external saphenous nerve lies superficially in the middle
line of the calf. As it is a sensory nerve, we pass from below
upwards, while giving light vibrations.
The external popliteal is best found behind the head of the
fibula, and frictions at that spot often produce a sparkling
.feeling in the foot.
Nervus Cruralis Anterior.
We can easily find this nerve where it lies in Scarpa’s triangle,
and apply frictions to it. Passing from it downwards and towards
the inner side of the thigh and knee, is the internal saphenous,
which is purely sensory, and is therefore more efiectively acted
upon by vibrations in the centripetal direction.
