A study published in the Journal of Orthopaedic and Sports Physical Therapy has shown the effects of acupuncture to be beneficial to neck pain.
17 patients with acute neck pain, were divided into two groups. One group received dry needling to trigger points whilst the other group remained untreated.
The treated group showed significantly better improvement with 33% reporting less pain immediately after treatment and 66% reporting less pain after 1 week. They also reported improved movement of the neck.
