Restricted Posterior Capsule and Restricted Shoulder Circles and Hypertonic Pectoralis Minor
Hypertonicity of the pectoralis minor, tightness in the posterior capsule of the shoulder and restricted shoulder circles are addressed together as each type of dysfunction is biomechanically related to the other.
Anatomy and Biomechanical Considerations:
Pectoralis Minor:
- Attaches to the superior margins of ribs #3-5 and inserts into the medial aspect of the coracoid process.
- Function: With the ribs fixed it anteriorly tilts and IR the scapula
- Innervation: Medial pectoral and a branch from the lateral pectoral nerves – C(6),7,8,T1
