The Schnee Four Cell Bath was used for treating general rheumatic
conditions and painful joints. A patient would be seated with an
individual bath for each limb. Each bath had its own current, which
could be varied independently. In this treatment patients could bear a
much stronger current than with electrodes on small areas, because of
the large skin area exposed to the current in each bath. There was no
danger of electric shock as in a full bath as the porcelain tubs were
not connected to water pipes and were well insulated from earthing. The
quantity of water required was not great and did not depend on a nearby
water supply. It also allowed the person to be treated without
undressing, speeding up treatment times and proving much more
comfortable and convenient than a full body bath.

Such devices were a common treatment for gout. It was essential for the affected limb(s) to be immersed in the hot water while the rest of the body remained at room temperature. Robertson Davies mentions this in his masterful "Deptford Trilogy", wherein the aged actor Sir John Tresize uses such a bath, albeit not electrified, for his gouty foot.
ReplyDeleteThis is very similar to today's treatment for hyperhidrosis. The treatment is called iontophoresis
ReplyDeleteIt looks very similar to the very early ECG machines: http://en.wikipedia.org/wiki/File:Willem_Einthoven_ECG.jpg
ReplyDeletePerhaps, when ECG recording technology had moved beyond immersing the limbs in water, the equipment/technique was repurposed for other uses?
I find it amazing that they were able to use sound reasoning and evidence to improve patient comfort and lessen duration of treatment without evaluating the effectiveness of their treatment.
ReplyDeleteIontophoresis is useful for driving ions (such as a medicine) into the skin with an electric charge. And reverse iontophoresis may be useful for driving uric acid (and its associated ions) out through the skin. But I don't understand at all how it would be useful for rheumatic conditions.
