A fasciculation, or muscle twitch, is a spontaneous, involuntary muscle contraction and relaxation, involving fine muscle fibers. You may be able to feel a fasciculation that is too subtle or deep to see.
Active trigger points can create a local twitch response. A trigger point is a dense area or knot within a taut band of muscle or myofascia. They can contribute to, or produce, local and/or referred pain.
Trigger points can be caused by muscular overload, fatigue or muscle trauma.
Benefits of massage with myofascial release include a reduced number of active trigger points, improved muscle function, improved joint alignment, improved self-awareness, mobilized fascia, an increase in stride length, enhanced relaxation and improved overall performance and recovery.
*This trigger point is so active it keeps twitching even when pressure is released.
