Effects of dry needling on pain, disability, kinesiophobia, pain catastrophizing and psychological distress in patients with chronic neck pain: A randomized controlled pilot study.

Abstract

Myofascial trigger points (MTrPs) in neck muscles seem to be related to the main symptoms of patients with chronic neck pain. The objective was to investigate the effects of dry needling (DN) on pain, disability, kinesiophobia, pain catastrophizing and psychological distress in patients with chronic neck pain. A double blind randomized controlled pilot trial was designed. Twenty-one patients with chronic neck pain were randomly allocated to the DN group (n= 7), Sham-DN group (n= 7) or Control group (n= 7). All groups received a Transcutaneous Electrical Nerve Stimulation and Therapeutic Ultrasound (TENS/US) protocol with patient education. The DN and Sham-DN groups received two sessions of DN and sham DN, respectively. The primary outcome was pain intensity. Secondary outcomes were disability, kinesiophobia, pain catastrophizing, psychological distress, self-reported improvement and success of blinding. The DN group showed a greater decrease in pain intensity, disability and pain catastrophizing compared to the Sham-DN group (p< 0.05) and the Control group (p< 0.05). The DN group showed the highest self-reported improvement. Adding two sessions of DN in active MTrPs in upper trapezius, levator scapulae and sternocleidomastoid muscles to a TENS/US protocol with patient education decreased pain intensity, disability and pain catastrophizing in patients with chronic neck pain.
