Those led to early TENS type machines like my doctor used on my broken arm in the 1960s and those led to solid state ones you can buy for $10 and now I have a Russian designed "smart" one.

Using one can be shocking, but yet enlightening as it zaps your muscles into action and fills you with energy.
