• It refers a pattern of pain at rest and/or on motion that is specific for the muscle
• An active trigger point is always tender, pre­vents full lengthening of the muscle, weak­ens the muscle, usually refers pain on di­rect compression, mediates a local twitch response of muscle fibers when ade­quately stimulated, and often produces specific referred autonomic phenomena, generally in its pain reference zone
• To be distinguished from a latent myofascial trigger point
