💥Clinical Findings for the Trapezius
Symptoms:
🌠The most common trigger points in the general population.

💥REFERRED PAIN PATTERNS
1️⃣Upper fibers: pain and tenderness, posterior and lateral aspect of upper neck. Temporal region andangle of jaw.
2️⃣Middle fibers: local pain radiating medially to spine.
3️⃣Lower fibers: posterior cervical spine, mastoid area, area above spine of scapula.
