Ultrasound shows the effects of acupuncture applied to trigger points. Take a look at these scans in action.

Ultrasound scans made by Jennie Longbottom and Mark Maybury at ALIED (Acupuncture Learning and Integrated Educational Development) show what happens in the body when acupuncture is applied.  A demonstration at the British Acupuncture Conference recently amazed acupuncturists from York Clinic when they saw blood flow increase at a point behind the knee (Bl40), when needling on the opposite leg. Also a ‘tsunami’ effect in the tissues on the torso (Sp 21) when needling stimulation was given to a point near the ankle (Sp 6). Maybe this is the beginning of our understanding of the mechanism of acupuncture from a biomedical point of view
