When Radiculopathy Isn’t Radiculopathy: A Clinical Series (Pt. 3)
When Radiculopathy Isn’t Radiculopathy

Before introducing subscapularis syndrome as an upper extremity analog, it is essential to revisit piriformis syndrome as a well-established example of myogenic pseudo-radiculopathy. Piriformis syndrome has long served as a clinical exception to disc-centric models of lower extremity pain and provides an important framework for understanding how deep muscular dysfunction can mimic radiculopathy in the absence of nerve root compression.

From Pain Scores to Performance Metrics
From Pain Scores to Performance Metrics

Pain has become the dominant language of musculoskeletal healthcare. Numeric pain-rating scales and symptom reports are routinely used as primary indicators of clinical success. But while pain reduction is meaningful, it is an incomplete and often misleading representation of recovery. This has real consequences for patient adherence, long-term outcomes, and how conservative care is perceived within the broader healthcare system.
