Hmm...as a scientist I look for answers to questions that are rational and work within what we know of the physical world, particularly in my case the nervous system. I have no experimental or experiential knowledge of the bracelets you refer to so I can only comment on this more generally. It is hard for me personally to think of a rational way products such as QRAY might work. The manufacturers state that 'Neither Q-Ray nor its independent distributors make any claim that our product is intended to prevent, cure, mitigate, treat, or diagnose disease.' (see http://www.duanereade.com/qray.htm) People with chronic pain which is not well treated by pharmacological means may end up trying various things. Some people may find wearing a bracelet appears to help them. One might argue that any benefit they get from approaches such as bracelets is due to 'placebo' effect - which means if you believe something is beneficial, your perception of your condition, or even in some cases your condition itself, may improve. I suppose also that if one is concerned about the safety of wearing a bracelet, one may get a reverse placebo effect, such that an increase in pain and or muscle tightening would be felt (even if the bracelet itself is doing nothing!). In all likelihood a metal bracelet is perfectly safe, it just might be not a great way to spend money. My own thought is that wearing any metal bracelet should be mainly for decoration not therapy, and should really not be relied upon for medical purposes. Peter
