Stiff muscle
Palpable taut band in muscle
Hyperalgesic muscle

Abnormal muscle use
Give away at ―critical load‖
Spindle injured
Initiation of cascade

Deconditioning caused by lack of exercise
Inadequate muscle use
Impaired posture
General factors: Nutritional deficiencies,
electrolyte disorders, metabolic or endocrine
dysfunction, sleep disturbances, or other
concurrent illnesses.

Trauma and ischaemia of muscle leads to
Central sensitisation
Supersensitivity in muscle leads to
Muscle shortening
Muscle becomes sensitised to palpation; a
term sometimes referred to as allodynia or
myalgic hyperalgesia

Injured sarcomere – improper healing—
contracted state---trigger points
Sympathetic innervation of intrafusal fibres
play role
Uncontrolled contraction—ischemia—release
of autocoids--

Energy crisis theory
Muscle spindle theory
Motor end plate hypothesis

Release of calcium from injured sarcomeres—
sarcomere shortening—increased metabolism
and compromised local circulation
Disparity…increased energy demand and
reduced energy supply due to impaired
circulation—ENERGY CRISIS--- release of
autocoids--pain

Dysfunctional muscle spindle—highly
localized electrical activity---this is
maintained by sympathetically mediated
factors like emotional stress
![Page 11: Myofascial pain etio pathogenesis dr rajeev harshe](https://reader031.vdocument.in/reader031/viewer/2022020218/55a76c4e1a28ab5c378b4616/html5/thumbnails/11.jpg)
Neuro muscular junction region
cause of trigger activity
Supported by
1. Clinical effectiveness of botox
2. Electrical activity noted in triggers by EMG
community
3. Length of propagation of spike potential
along length of taut band
