A veterinarian needs 2 years of training to insert filiform needles into the body of animals. However, some healthcare groups, or even non-healthcare groups, want to take an extremely irresponsible short cut to insert needles into the body of a human being with only 50 hours of training. That is insane!
If they want to do dry needling, they need to have sufficient training to reduce the chance of causing severe adverse affect including pneumothorax (puncture of the lung), infection and nerve damage. Sufficient training of dry needling by a non-MD healthcare provider means equivalent to that of an acupuncturist.
