A device includes light sources, electromagnetic field generators, and vibration components to apply a variety of treatment regimens to a living animal organism, including a human person or a body part of a person. The light and electromagnetic therapy are applied at frequencies which have physiological effects, and which can be combined to induce lipolysis, stimulate muscle, and achieve other effects. Feedback is used to dynamically adjust the intensity, duration, and other parameters of the light, electromagnetic, and vibration treatment modalities.
