Humeral part
Client is supine with the elbow in a 90 deg. flexion and forearm in a neutral rotation. Stabilize the elbow and apply pressure around the wrist area towards elbow extension – Trying to pull the forearm away from the humerus.
Septal part
Client is supine with the elbow in full flexion and forearm in a neutral rotation. Stabilize the elbow and apply pressure around the wrist area towards elbow extension – Trying to pull the forearm away from the humerus.
