Percutaneous Electrolysis Versus Dry Needling in Levator Scapulae

The objective will be to determine the effectiveness of ultrasound-guided percutaneous electrolysis versus ultrasound-guided dry needling in active myofascial trigger points of the levator scapulae muscle on pain intensity, disability and range of motion. A randomized clinical trial will be carried out. Fifty-four patients with at least one active myofascial trigger point in the levator scapulae muscle were recruited and divided into ultrasound-guided percutaneous electrolysis (n = 27) and ultrasound-guided dry needling (n=27). Pain intensity, disability and range of motion will measured before, immediately after and 1 week after intervention.
