Q

What are the five overall categories of shoulder conditions?

A
  • Instability (Hypermobility)
  • Hypomobility (Adhesive Capsulitis)
  • Rotator Cuff Conditions (Tendinopathy, Partial-Thickness Tear…)
  • Intra-Articular (Mostly Labral)
  • Extra-Articular (Mostly Biceps & AC joint)

These categories help in classifying shoulder conditions to aid in diagnosis and treatment.
