edy,If you want info for playing with the machine, you have to search some medical book or ebook about Electromyography ,where you will teach as polarizes the muscles and the used frequencies .
When i was operated of the my broken elbow, before to entered to operation room , in the preoperation room the anesthetists used with me a nerves tester , they stabbed between 3 or 4 hypodermic needles
on my neck(near the cervical nerve neck) with the goal to find the nerves elbow(cubital,radial and median).
When they powered on the machine, my arm seemed a rodeo's horse, it didn't stop to bounce. After i entered at operation room and the medics put me 2 nails and an obenque.
6 month later I developed a strange stuff on my operated arm. i began to have muscle spasms. The Biceps and Triceps muscles were continuously contractions,the muscles forearm sometimes went up until 4 cm and i couldn't move in circles my forearm without doing strange movement with my body.
Then the medics began to do me proves, they did me an other kind nerve tester, this tester measurement the time response , the overshoot signal and the settlement time on the nerve. This was OK
Frustrated with the medical community, I start pushing on all of the teeth in that area with my finger.
I had two solution for controlling the spasm: The first i found casually, it was caught the forearm muscles package and pulled go to up and the spasms dissapered and i could rotate the forearm
The second solution was given for Electromyography medic, i had to concentrate in some stuff, and this method work a 80%
Since this moment , i began to suspect of the nails elbow and i told to the medic that operated me , but she told me that never had seen case as mine .
At March ago,i was reoperated and she took off me the nails, and the same day at the home when i recovered the sensibility of the arm, the spasms disappeared
