What are “taut bands”? How are they associated with trigger points?
In patients with myofascial pain, deep palpation of muscle may reveal areas that feel tight and bandlike. Stretching this band of muscle produces pain. This is a taut band. Trigger points are characteristically found within taut bands of muscle. Despite the muscle tension, taut bands are electrophysiologically silent (i.e., the electromyogram [EMG] is normal). Rolling the taut band under the fingertip at the trigger point (snapping palpation) may produce a local “twitch” response.
