If I may offer some info. I have been a practitioner of ART for about 3 years now with some outstanding success with CTS patients. The real key is to locate where the nerve is entrapped. This is commonly in one or more of 5 places: the ligament of Struthers, pronator teres, pronatore teres/flexor digitorum superficialis, carpal ligament, and the thenar muscles.
While it is a soft-tissue treatment, I would not classify it as massage. It is rather more intense with a "hurts so good" kind of feel (no worse than your big brother giving you an indian burn).
While I use a number of manual techniques in my practice, I would definitely have to say that Active Release Techniques are the more powerful tool in my tool box. It's effectiveness is more often than not immediate with most diagnoses resolving in just a few visits.
