The Dynatron STS

Dynatronics is a medical manufacturer based in SLC. I would not doubt they make an interferential unit you have used in a PT clinic. Their Dynatron STS is an interferential unit and complimentary computer software designed specifically to electrically stimulate the sympathetic system. I have had correspondence with the manufacturer and even visited their facility to see manufacture and real clinical use first-hand. The Dynatron STS probably should not be considered a quack device any more than many other electric therapy devices used by therapists (few or none will stand up to comprehensive scientific efficacy analysis). Because STS therapy is often directed toward the "incurable" idiopathic or multi-etiologic chronic pain sufferer, and treatment is frequent, long-term, and costly, it's often just what quacks like to order. The developing clinicians of the STS are not too interested in comparative studies and may cite patient population and individualized protocols as reasons against them. Worker's Compensation covers it sometimes, and that is likely why the State of Washington had the quackwatch published analysis done.

Rather than a quack device (akin to the zapper, or Diapulse), the Dynatron STS is more of an FDA approved electric stimulator that hasn't yet demonstrated a comparative and predictable positive cost-benefit ratio. It doesn't attest to depend on any action or intervention with life-force or qi etc. At worst, STS is a questionable technology or therapy protocol.

Nevertheless, state, VA, CMS, and private insurance technology assessments are an excellent source for verifiable information about technologies posing as legitimate medical treatment. I hope you and quackwatch will continue to site these references.
