Trigger Point Dry Needling for Chronic Tension-Type Headache

"The trigger point DN procedure was performed by a certified physiotherapist. While the patient was sitting, the therapist firstly cleaned the area with alcohol. Then, DN was applied into the active TrPs on the basis of the technique described by Hong (19). The needle remained in the trigger points for 20 minutes. Upon removal of the needle, the area was compressed firmly with a cotton swab for 60 secs. The DN procedure used sterile stainless-steel acupuncture needles of 0.25x40 mm and 0.25x 25 mm dimensions (Hua Long ®). DN was applied three times a week for 2 weeks, in previously diagnosed active trigger points located in the musculature of the head and the neck.~the Sham Dry Needling procedure was applied into the adipose tissue located at any area where an active TrPs was absent."
