Only one session of a Trp-DN intervention in the Quadriceps Vastus medialis muscle in conjunction with a rehabilitation protocol in subacute patients with surgical reconstruction of the Anterior Cruciatum ligament increased range of motion in short term and functionality short- to mid-term. These effects were superior to the intervention group that only followed the rehabilitation protocol.

Neck Pain

The risk of suffering from neck pain in office workers is very high. Continous computer work and jobs with static neck/shoulder positions may be related to the presence of MTrPs, especially in the trapezius muscle. The following study compares deep dry needling of active MTrPs found in the trapezius muscle together with passive stretch, compared to only passive trapezius muscle stretch. The primary outcome was pain intensity (VAS); the secondary were pressure pain threshold, cervical range of motion and muscle strength. Overall deep dry needling combined with passive stretching seems to be more effective in decreasing pain than the passive stretching alone. It also has the bigger benefit on the secondary outcomes!

Adverse events

Currently, this is the only study that investigates the safety of Dry Needling. In over 7500 treatments there were no significant adverse events such as a pneumothorax or systemic events. In 20% of the treatments there were mild adverse events including bruising, bleeding and pain. The study shows, that Dry Needling is a safe and effective way to treat myofascial pain when applied by therapists, who attended the DGSA-curriculum.
