Having had to use a TENS machine for pain relief recently, I soon got bored with the stored patterns of electrical stimulation (to which the muscles adapt very quickly).
So I thought that today’s invention should be a new TENS device in which the electrical signals are driven by the frequencies of the wearer’s music being played on his/her MP3 player.
This would help the therapeutic effects of listening to music and provide a much wider variety of massage for the tissues.
