There’s been a lot of chatter on Yahoo’s popular CMTUS chat group lately about a pain-relief technique called “Intramuscular Stimulation” or IMS, developed in the ‘70s by Dr. C.C. Gunn, a pioneer in the treatment of pain and president of the Institute for the Study and Treatment of Pain in Vancouver, Canada.  In Gunn’s words, Gunn IMS is a “safe and effective technique” using needles for treating 'the shortened muscle syndrome.'  Since the discovery, doctors from the US to Europe have been applying the therapy to treat everything from low-back and knee pain to myofacial or soft-tissue pain. For CMT patients, the treatment offers relief for a host of painful symptoms.
