Episode Summary: Trapezius Myalgia – Understanding Upper Trap Pain and How to Treat It

In this episode of the Rehab Science podcast, Dr. Tom Walters, DPT, breaks down one of the most common sources of neck and shoulder discomfort—trapezius myalgia. Often experienced as persistent tightness or aching in the upper trapezius muscle, this condition affects individuals who spend long periods sitting, working at a computer, or holding static postures under stress.

Dr. Walters discusses the underlying anatomy and biomechanics of the trapezius, highlighting how postural overload, fatigue, and nervous system sensitization contribute to chronic discomfort. He explains why passive strategies like stretching alone may be insufficient, and emphasizes the role of progressive resistance training in improving muscle function and reducing symptoms. The episode concludes with practical movement strategies, rehab principles, and key behavioral tips for lasting relief.
