Yes, I tried ActiPatch three times: two 72-hour versions and one trial version. It didn't work for me at ALL.
That is my testimonial. The FDA doesn't like testimonials and neither does the CMS, and I agree with them. I don't care whether you give the ActiPatch "FIVE STARS" on your own personal little Star Search episode and you don't care that I say the device didn't work for me. Testimonials are worthless, IMO.
BIEL acknowledges that ActiPatch does not work for everyone. BIEL cannot explain the science behind the fact that ActiPatch works for some people and not others. I've heard hypotheses like "muscle mass" and "it works better on women than men" but it's all guessing, and that bothers me. I like science.
Yes, I've heard the theory that opioids cause the ActiPatch to not work. FYI, I was not taking opioids when I tried the ActiPatch.
I just bought another 720-hour version from that $15 DonJoy sale. I plan to do my own experiment the next time I have a surgery incision: I'm going to place the device over half of the incision. If that half heals faster, that's proof that the device has SOME benefit. Currently, though, I don't see convincing evidence that the device has any benefit other than placebic because I think all the positive clinical studies are underpowered, as were the negative clinical studies I just cited, including Ilfeld's.
And really, it doesn't matter whether the device works or not. What matters is: does it sell. Historically, it has not. It's a disposable device which means the company needs repeat loyal customers, and to date, every spike in revenues resulting from a promotion has been followed by flat sales. If this device was such a "FIVE STAR" device, that wouldn't happen.
