A recent systematic review by Kietrys et al (2013), provides us with level 1A evidence in support of what we as clinicians using Dry Needling for Myofascial Pain Syndrome (MPS) have known for a long time....it works!
In the meta-analysis, twelve quality RCT’s were selected which met the following inclusion criteria: human subjects, dry needling intervention group, and MPS involving the upper quarter. The methodological quality scores ranged from 23 to 40 points, with a mean of 34 points (scale range 0-48, best possible score-48) using the the MacDermid Quality Checklist.
The authors concluded:
Based on the best current available evidence, we recommend (Grade A) Dry Needling, compared to sham or placebo, for decreasing pain (immediately after treatment and at 4 weeks) in patients with upper quarter MPS. Due to the small number of high quality RCTs published to date, additional well-designed studies are needed to inform future evolution of this recommendation.
