In the diagrams the stationary application of light to a single point on the skin is represented by dots and arrows. Smaller LED devices can apply light to a discrete point. For ease of use, the diagrams are only front and back views of the body. Therefore, any point that is applied to the side of the body not pictured is noted by an arrow and the frontal, visible view of the skin is demonstrated by a dot. These points correspond to anatomical locations, not acupuncture points. Shading denotes that the light is applied in smooth, even strokes called Painting, which is a slower, more methodical ultrasound application. This is described in the first chapter, Science of Light Therapy. Most conditions respond to both Point and Painting techniques.
The recommended dosages in this text are based on using an LED with a total output power of between 10 and 10,000 mW. Please refer to the chart at the beginning of each DIAGRAM section for details on dosages for any device between 10 and 10,000 mW.
Ice and Heat
When the application of ice or heat is recommended, it is assumed that the patient can, depending on the practitioner’s bias, use ice in the most acute stage, progress to alternating ice and heat as they become subacute, and use heat when the condition is not characterized by serious inflammation.
