The digestive tract contains a smooth muscle cell layer (the muscularis externa) having no motor innervation. Pacemaker cells located throughout the digestive tract send signals to the muscularis externa. This causes rhythmic waves of muscular contraction and propels material through the digestive tract.

Vasodilation leads to an increased blood flow and is responsible for the redness and heat of an acute inflammation. As fluid continues to concentrate in the area, the permeability of tissue is exceeded which leads to swelling and edema.

To conduct the Adson maneuver, a massage therapist places the clients arm into horizontal abduction on the affected side to a 45 degree angle while rotating their head toward the affected side. The massage therapist then instructs the client to extend their head which tightens the scalene muscles, which should magnify any preexisting compression of the subclavian artery and brachial plexus. The massage therapist palpates for a decrease in the radial pulse while the client takes deep breathes to exaggerate the compression.
