Q

Define Scapulohumeral Rythmn.

A

Describes the movement relationship between the shoulder girdle and the shoulder joint.

16
Q

Define how the Scapulohumeral Rhythm works.

A

The first 30 degrees of the shoulder joint movement is purely in the glenohumeral joint.

After the first 30 degrees, every 2 inches of shoulder flexion or abduction the scapula rotates 1 in.

Rhomoid Muscles      Ride
Serratus Anterior        Some
Pectoralis Minor         Penis
