Dry needling is when a physical therapist inserts tiny filiform needles (similar to those used in acupuncture), into the trigger point. The needles then can be gently moved to stimulate blood flow to the trigger points, which may help relax tight muscles. Researchers believe the technique blocks pain signals but aren’t sure how dry needling relieves pain.
Researchers know it works. Patients often feel relief immediately after the session lasting from hours oe weeks. Researchers recommend that dry needling be integrated into a larger treatment plan, which includes other back pain therapies like gentle exercise and spinal injections, to get the maximum benefits.
