What do amplitude, pulse width and pulse rate mean?
If you picture in your mind an EKG waveform, the amplitude is the height of the spike, the pulse width is the length of time it stays at the top of the spike, and the pulse rate is the number of spikes per second. How do you decide what parameters to set? There are pretty well established starting parameters that researchers agree are effective for a lot of people with similar symptoms. But one size does definitely NOT fit all. Most programmers will start with a conventional setting, and then take it in whatever direction the patient needs to go based on responses and side effects. What are unipolar and bipolar? To create an electrical current you need a cathode and an anode. A negative and a positive. The generator battery pack in your chest is referred to as the case. The electrode in your brain has 4 contacts: 0 1 2 3. The deepest one is 0, and the top one is 3. Unipolar means that the case is positive and one or two or all of the contacts are negative. For example, case + 0-. This
