Trigger Point Dry Needling (TDN) is a physical therapy treatment technique that utilizes filament needles to make changes in myofascial trigger points.

Trigger point dry needling is a form of physical therapy that uses a thin filiform needle to penetrate the skin and stimulate underlying neuromuscular trigger points. This treatment aims to release the tension within the trigger point that may be causing pain, abnormal movement patterns, or chronic tightness.

Dry needling physical therapy should not be confused with acupuncture as it is based on Western medicine principles and targets trigger points found by a physical therapist during an examination. These trigger points could be caused by poor posture, athletic overuse, chronic pain, or trauma-related conditions.
