| Hidrex shows true measured average voltages on its screen | |

| Ok, I see, thank you for the correct conclusion! For the hidrex: (P-50%, 35V) - Average Voltage is 35V (P-90%,30V) - Average Voltage is 30V One query is: In Hidrex's Pulse mode, does the screen show Average or Peak Voltage? thank you! |

| that is not correnct: i just mentioned that some devices state the average current (like hidrex) and mostly all others state peak currents (out of tiny batteries) - sorry that this seems to cause some confusions For the hidrex: (P-50%, 35V) - Average Voltage is 35V (P-90%,30V) - Average Voltage is 30V For some other devices A: (P-50%, 35V) - Peak Voltage = 35V, Average Voltage= 17.5V B: (P-90%,30V) - Peak Voltage = 30V, Average Voltage= 27V in the example above, this is not really heavy, but some devices have really great pauses (can be seen with a oscilloscope) caused by tiny batteries: EXAMPLE: (P-10%, 35V) - Peak Voltage = 35V, Average Voltage= 3,5V as good as nothing!!! Tha right Conclusion: In pulse mode "A measured higher Average Voltage is more effective than a fantasy Peak Voltage shown by a display! |

Many thanks for your explanation! I repeat this discussion as below:
A: (P-50%, 35V) - Peak Voltage = 35V, Average Voltage= 17.5V B: (P-90%,30V) - Peak Voltage = 30V, Average Voltage= 27V Even B's Average Voltage is higher than A's, but A's Peak Voltage is higher than B's. Conclusion: Higher Peak Voltage is BETTER than higher Average Voltage! Please advise if my understanding is correct or not? |

| yes it is, iontophoresis is a treshold and current driven therapy the treshold is the level you have to get higher to have an initial success (better reachable with smooth pulsed current) and the efficiancy depends on the dosage (current in a certain time) - this means : smooth pulsed current - higher currents are possible - through this the time is reduced to bring in a certain dosage for your extract of the post:
this is only right for a iontophroesis device telling you the average current and not the iontophoresis peak levels (like so many other devices on the market do - i dont want to be rude to others, but this is the poor fact for most iontophoresis machines out there) |

|
| In one post, it was advised that (P-50%, 35V) is surely better than (P-90%,30V), does it mean the higher voltage is the ONLY main success factor? | |

| Both is right, higher Voltage (U) is coupled with higher currents in mA (I) It is the body resistance (R) that is the constant in this calculation on ohms law U=R•I |

|
| After reading the posts, it seems one post mentioned it is voltage level which is the main factor to achieve success. While, on the other hand, another post suggested it is certain current level to achieve success. Which one is the correct one? please advise, thank you! |

|
| Direct Current = DC = strong current feeling Pulsed Current = PC = smooth current feeling First of all, there are 2 basic things: 1. DC and PC are equally effective at a same current level. This means for example, a DC machine at 12mA is equally effective than a PC machine at 12mA. The only difference is how you will feel the current. With a PC machine you will most likely be able to stand higher currents, since the current feeling is very comfortable and smooth (and through this the time you have to spend in iontophoresis is reduced the same way: e.g. if the current is raised to the double amount , it reduces the time needed to bring in the same dosage by 50%). On the other hand, with the DC machine, you probably will start to feel pain at very low current settings. 2. Every person needs a certain current level to achieve success. If a person treats below this current level, then there will most likely not be any success at all, no matter how often this person treats. So the math is very simple! Let's say, our test person needs a current level of 18mA to achieve success and she has a DC machine. With this machine this person can only stand 10mA. So this is 8 mA below the current level that she would actually need to achieve success. So it doesn't matter how long and how often she treats, there will most likely not be any success at all. Instead, with a PC machine, chances are very high, that the test person will stand more than the 18 mA needed. Now you probably ask yourself, how do you know what current level you will need, in order to determine wether you really need a PC machine or if a DC machine would be enough? The thing is, there is not really a way of knowing which current level you will need. It is certain, that everyone has his own current level, but you can't determine this in advance, before buying the machine. If you have done Iontophoresis before, then maybe you know at which current settings you had success. The best thing in the end with a professional pulsed current iontophoresis machine: with higher currents the treatment times you have to spend with iontophoresis are reduced the same way - iontophoresis is also a dosage driven therapy form, means: higher currents brings in the same dosage in shorter times! So if you prefer not to take any risks, then go with a PC machine. There you're on the safe side. But you can also go with the DC machine first, maybe the current level that you need to achieve success is very low and you are lucky and can stand this current level with direct current. But these are the rare cases. Most of the time, when using a DC machine, users aren't able to even get near the current level they will actually need to achieves success. As you can see, it is not only a matter of with which machine you will most likely achieve success, it is also a matter of choosing between a painful and uncomfotable therapy or a nice and smooth therapy. And for the latter, PC machines are much better suited. |
