Trigger Point Dry Needling for Chronic Tension-Type Headache
Trigger Point Dry Needling for Chronic Tension-Type Headache
In this double-blind randomized trial, we aimed to explore the effectiveness of trigger point
 dry needling in patients with chronic tension type headache (CTTH) in reduction of headache
 frequency, intensity, duration, and improvement of health-related quality of life (HRQoL).A
 total of 160 CTTH patients participated in this double-blind, sham-controlled randomized
 trial. The patients received dry needling using sterile stainless-steel acupuncture needles
 of 0.25x40 mm and 0.25x 25 mm dimensions three times a week for 2 weeks. The primary outcome
 measurement which was the headache intensity and, the secondary outcome measurements which
 were the headache frequency and duration were collected using a headache diary before and
 after treatment. Another secondary outcome measurement which was the health related quality
 of life was measured before treatment and at the end of the 1-month follow-up period. HRQoL
 assessments of patients were performed using Short Form-36 (SF-36). In the dry needling (DN)
 group, both the primary outcome measurements and the scores of SF-36 subscales were
 significantly improved after treatment. In the DN group, all effect sizes for headache
 variables were large. The results of this clinical trial suggest that trigger point dry
 needling in patients with CTTH is effective and safe in reduction of headache frequency,
 intensity, duration, and increasing health-related quality of life.
According to the 2013 Global Burden of Disease study, recurrent tension-type headache is the
 second most common chronic disease worldwide, with an age-standardized prevalence of 21.75 %
 (1). Although high prevalence of chronic tension-type headache (CTTH) has been reported in
 all world regions, it is also the most neglected disorder and it leads to headaches that are
 difficult to treat (2). Myofascial pain can play an important etiologic role. It has been
 claimed that pain from pericranial head, neck and shoulder muscles is associated with the
 head and experienced as headache (5, 6). Within the cervical musculature, there are several
 head and neck muscles, eg. temporal, masseter, upper trapezius, sternocleidomastoid,
 temporalis, sub-occipital muscles, from which trigger points (TrPs) spread referred pain to
 the head (6). There are several pharmacological and non-pharmacological therapies for
 patients with CTTH. Physiotherapy is the most commonly used non-pharmacological treatment of
 CTTH. Although sports and orthopedic physiotherapists have used dry needling (DN) for a long
 time to address the pain and dysfunction associated with myofascial trigger points (11),
 there is insufficient evidence to strongly advocate for use of DN for treatment of CTTH (12).
 In this double-blind randomized trial, we aimed to explore the effectiveness of trigger point
 dry needling in patients with CTTH in reduction of headache frequency, intensity, duration,
 and improve health-related quality of life (HRQoL).
