Click for a picture of the Infrex waveform as seen on an oscilliscope type device. Wanted to brief you on what we are looking at here and more importantly why.
Several important observations:
1. The bottom line is called the "baseline" and it is a straight horizontal line that represents no electricity is coming out of the Infrex Plus, in other words machine off.
2. The first vertical line up on left side shows the electricity being released, or a cycle starting, with a cycle being the beginning of the release of the electricity until the machine is turned off and returns to baseline.
3. The sharp vertical line going straight up means the unit is strong enough to go straight up and not on an angle. Angles, slight lean to right, are indicative of less power ( wave decay) and the resistance is overcoming the charge. That verticality is a good sign of a good unit.
4. Horizontal line at top is staying horizontal, not decaying, which would be depicted as the line going from left to right declining while the unit is on. This assures the unit is overcoming resistance and maintaining the integrity of the charge.
5. Straight decline on right side showing unit turning off electricity and returning to baseline immediately, no slow ramp down. The process of on, hold and off is a cycle of which the Infrex Plus does this over 8,000 times per second ( pulses per second - PPS).
This was filmed as a slight moment of time in treating a shoulder. What is important is to achieve immediate lasting benefit you must receive enough power capable of overcoming resistance and effecting chemical change. The power must be sufficient that you actually feel the stimulation. The integrity of the process is what makes a unit beneficial and possible for you to get immediate results and lasting carryover pain relief. You will see at the bottom that the Infrex Plus is only at 25% of it's available power during this time period. As a general rule there is not a problem when a unit has too much power as the amount of power can not be increased if the patient can not tolerate it, but if there is not enough power to obtain relief then there is a problem since you can't get out of an interferential unit what is not in it, ie. not enough power.
