MFP are often confused with what?

What, generally, are myofascial trigger points?
Taut band in the muscle, which refers pain to a distant location when compressed
What happens to muscle fibers with contraction knots?
Knotted area pulls on the remainder of the muscle fiber, causing excessive stretching
What two muscles often refer pain?
Trap and SCM
What causes TrPs?
- Acute overload
- Overwork
- chilling of muscle
- Nerve injuries
What is meant by the term satellite TrPs?
Central TrP induce neurogenically by the activity of a key trigger point
occurs in the referral patterns of the key trigger points
What is a latent TrP?
Clinically quiescent with respect to spontaneous pain
Painful only when palpated
What are active TrPs?
TrPs that cause pain and TTP at rest or with motion that stretches or loads the muscle
Causes shortening of the muscle, as well as fatigue and decreased strength
What is the sequence of events that cause the development of TrPs?
taut bands of muscles, leads to latent TrPs, which are turned actie through stressors
True or false: active TrPs refer pain in a predictive pattern
True
