Opinions may vary, but I find that the technology really helps me stay active, and when I do hurt myself (inevitably), I am able to recover much more quickly.
The recent nursing study/dissertation on the use of this technology for all types of pain is here:
You can read what many other people have to say about using this technology for pain and increased activity and functionality, how well it works for them, how long it lasts, etc.
Note: this was an IRB-approved descriptive study, and I was strictly not involved in data collection or analysis. The dissertation included all comments and observations whether they were favorable or not.
DISCLAIMER: this is my technology, of course. But this is why I designed/built it in the first place.
