A Novel Therapeutic Approach Targeting Spinal Accessory and Dorsal Scapular Nerves for the Relief of Posterior Neck, Trapezius, and Interscapular Pain.

Posterior neck, trapezius, and interscapular pain, exacerbated by poor posture such as forward head and rounded shoulders, is common. In this study, we aimed to assess the clinical outcomes of isotonic saline injections at nerve entrapment points (NEPs) within the sternocleidomastoid (SCM) and scalenus medius (SM) muscles for alleviating spinal accessory nerve (SAN) and dorsal scapular nerve (DSN) compression in patients suffering from posterior neck, trapezius, and interscapular pain. In this retrospective study, 68 patients were included, with 34 receiving isotonic saline injections and 34 undergoing Extracorporeal Shock Wave Therapy (ESWT) as a control.
