Now this is good information! If anyone is going to spend serious money on an EMS unit, I want to know why, and this is helping. I’m still not sure how big of a comfort difference there is between 330 microseconds and 450 microseconds considering this only applies to one muscle group as related to max strength.
Is there any reason that the top units (e.g. those with 8 electrodes) don’t allow custom programs? Is this a safety / certification issue in North America? If so, will manufacturers input programs of my choosing as standard?
With regard to some units having 6-10 seconds on, 50 off protocols as standard, I haven’t carefully researched EMS units recently, so if there are commercial units available it would be nice to know about them.
