Unlike traditional injections (which use medication), no liquid or substance is injected into the body. The therapeutic effect comes solely from the needle's physical manipulation of the tissue.
When the needle penetrates the knot, it often elicits a "local twitch response"—an involuntary muscle contraction. This indicates that the trigger point has been properly stimulated and is beginning to release.
The tiny microlesions created by the needle stimulate a natural healing response, encouraging increased blood flow and helping the nervous system reset the muscle's resting tone.
