Dry needling versus muscle energy technique in treatment of latent trigger point upper trapezius

The main cause of Myofascial pain syndrome is trigger point. The purpose of this study was to compare muscle energy technique (MET) with dry needling (DN) on latent trigger point of upper trapezius.
Fourty females, with diagnosis of latent trigger point of upper trapezius after adopting the inclusion and exclusion criteria were equally and randomly allocated into either the muscle energy technique or dry needling groups. Each patient received one treatment to the upper trapezius muscle. Outcome measures (visual analogue scale (VAS), pressure pain threshold (PPT), and range of active contra lateral flexion (CLF) measured before and 48 hours after treatment.
Two techniques which used in this study were effective for treating latent trigger point of upper trapezius (P0/05).
This study demonstrated that muscle energy technique was as effective as dry needling in improvement of VAS, PPT and ROM in subjects with latent trigger point of upper trapezius muscle. But since muscle energy technique is safe and non-invasive method, therefore, if you want to select one of these two techniques, muscle energy technique is recommended.
