actually, there are approved devices that do similar things and they are
sometimes used in physical therapy.  you can distract muscles and stop
spasms, you can also greatly reduce minor pain.  i used one all the time
after my third back injury and even drove with the wires under my shirt,
two electrodes on the low back on two channels with the other end of the
circuit being an electrode on each hand by the thumb (at the acupressure
or acupuncture points, and those spots on the hand actually do become
tender when the back acts up, and pressing on them does make the back
hurt less, the brain is wired in some odd ways, there seems to be
serious cross talk).

very effective at reducing pain until after my last back injury (in
conjunction with muscle relaxants and pain meds), now the irritated
nerves are too deep for surface stimulus to get to very much.  you just
have to remember to always adjust the level of a given channel with the
hand on the other channel!  it's really hard to turn back down if you
accidentally bump it too high on the hand that's on the control!
unfortunately other than sometimes also helping muscle spasms they don't
seem to promote healing, but pain relief is important.  the insurance
company bought me mine and it's a nice one, well they finally bought me
a good one after 2 cheap ones failed within a month or so.  it actually
produces more complex wave forms than you mention, my favorite is pulses
at and increasing rate that then top out and drop back down in speed
every coupled of seconds, and there are other patterns depending on the
type of pain and the individual.  they are a simple circuit and just use
a transformer to isolate the output so you can have 2 or more
independent channels.
