Not quite as much lately, especially in view of the article quoted by Avi.
First, pain can be difficult to quantify; and when that is the case,
anyone other than those who suffer the pain is in a position to judge
whether something works --or not.
In any case, if Avi suffers pain for which there is no relief--other than that which he does not acknowledge;
well, I cannot comment. --but, I am thinking it!
CR is correct in this respect, although it summarizes something technical down to two sentences. Alas, CR has over the years, also shrunk its magazine and lists of products, as readership has declined (died....) and younger people don't give a damn about product quality, and/or rely more on free online information sources for advice. Where there used to be dozens of items shown in each test, now the print magazine prints only the top five or ten items. The lesser products tested get cut off, only to be seen on the online website, for paying subscribers.
Anyway yes, it's correct. Even, in his own way, Avi is. A TENS unit doesn't cure or help anything it simply blocks the body's pain signals to the brain, tricking it with 'distracting' other signals. But, much as an anesthetic doesn't heal the actual trauma requiring the anesthetic, the blocking of the pain signals is more than a sufficient benefit for the patient.
