This weekend we will explore the influence of scapular positioning, scapular stabilization and the phenomenon of reciprocal inhibition as possible hidden factors in neck, hand and rotator cuff function. Also considered is the role of muscles that act as Relocators of the humeral head into the glenoid fossa during strong distractive forces produced during arm movements.

The scapulo-thoracic articulation is the "Hidden Nemesis" in many shoulder complaints. Improper feedback from proprioceptive mechanisms in this area disturbs the intricate balance of the shoulder girdle's rhythm. The price of this imbalance is often paid by the gleno-humeral and the acromio-clavicular joints. Recognizing, understanding and properly addressing this articulation will result in better harmony within the symphony of shoulder movement.

This weekend will be divided into four sessions:

• Scapular Positioning: Pectoralis minor
• Scapular Stabilization Serratus Anterior and Rhomboids
• Reciprocal Inhibition: Anterior Serratus and Latissimus Dorsi: Hidden Nemesis in Neck Function.
• Relocators: Coracobrachialis and Long Head of the Triceps

The purpose of the shoulder girdle is to allow for placement of the hand in a functional position.

Weak scapular muscles may prevent the humeral head from clearing the acromion process completely. This may lead to subacromial impingement.

By understanding and applying basic laws of stabilization and reciprocal inhibition, you will learn and experience the effects of distal imbalances on scapular positioning and the resulting neck, hand and gleno-humeral joint function.
