Ashi acupuncture is the treatment performed to release tension within painful knots within muscles, known as myofascial trigger points.
Trigger points frequently cause pain that can radiate from tender spots within a muscle to broader areas, sometimes quite faraway from these points. The phenomenon of trigger points are firmly established in Western medicine.
Treatment of trigger points varies. It may involve manual massage, mechanical vibration, ultrasound therapy, electrical stimulation, manual compression, anesthetic medicine, steroid injection, cold laser therapy, stretching techniques, and of course, acupuncture.
Is Ashi acupuncture similar to what is being called dry needling?
Dry needling is claimed to be different from acupuncture because the needles are not placed according to Chinese energy meridian points, but rather in trigger points. Dry needling is performed by Western medical practitioners, often physical therapists. Many physical therapists justify the notion that dry needling is distinct from acupuncture because it doesn't involved discussion of improving energy flow within the body's meridians (energy channels), as in Traditional Chinese medicine. The needles are being used directly in problem areas.
Many acupuncturists tend to passionately disagree with the term dry needing because of the simple fact that acupuncture needles are being inserted into the skin for pain relief. In my opinion, dry needling is an acupuncture method performed by non-acupuncturists, disguised as a Western medicine innovation.
Is this important? I don’t think so. Patients don't care what doctors call treatment techniques; you care whether they can help, or not!
There are a tremendous number of acupuncture techniques that have been used throughout the world over thousands of years. However, I generally don’t like when conventional Western medicine takes things they’ve criticized as “alternative medicine” and rename or repurpose it with the claim of a new treatment.
