Starting Position: P: Supine or sitting; elbow flexed approximately 90° and steadied against the couch; wrist in neutral position. T: Standing facing P's right side.

Procedurę: Using this grip, T gradually and fully abducts P’s thumb and simultaneously applies traction.
Stimulation of Antagonists: T retains grip. T then asks P to move further in the direction of stretching, and resists that movement to stimulate P's antagonists.
Notę: For maximal stretching, P's thumb should also be medially rotated.
