These rapid hand-over-hand movements are designed to lift and stimulate the sternocleidomastoid, which pulls head towards the chest and tightens the neck; and the platysma, which covers the entire front and sides of neck area. The upward direction of this effleurage massage movement lifts up tissue, stimulating muscles, nerve endings and also the carotid arteries. It also greatly helps to relieve neck tension.
