Summary

Myofascial pain is an important cause of neck pain or neck and shoulder pain. Neck shoulder pain is a common socioeconomic problem that negatively affects the quality of life. Different treatment strategies with limited effectiveness or application have been implemented. However, medication remains a widely used approach.

The levator scapulae is one of the muscles involved in myofascial pain leading to levator scapulae syndrome. The muscle limits the rotation of the neck. It is innervated by branches of the third and fourth cervical nerves through the cervical plexus. Hence, performing superficial cervical plexus block may have some potential effect in reducing myofascial pain.

  • Shoulder Pain

Interventions

OTHER

Superficial cervical plexus block

A nerve stimulator is used to guide the superficial cervical block. The nerve stimulator needle is first passed over the skin after aseptic preparation from the distal to proximal part of the posterior border of the sternocleidomastoid. Upon contraction of the levator scapulae, a mark is placed and the skin is infiltrated with 1 ml lidocaine 1%. A 22-G, 2.5 cm nerve stimulator needle is subsequently advanced through the skin by 0.5-1 cm depending on patient's weight while passing 5-8.5 mA current at 1 Hz. Then, the stimulating current is reduced to 0.5-0.6 mA while maintaining muscle contraction. At this point, 3-5 ml of the anesthetic mixture is injected.
