Stiff muscle

Palpable taut band in muscle

Hyperalgesic muscle

Pain which can be unbearable

Pain not responding to analgesics

Pain lasting for long times

Emotional distress,Physical Distress

Page 4: Myofascial pain  etio pathogenesis dr rajeev harshe

Abnormal muscle use

Give away at ―critical load‖

Spindle injured

Initiation of cascade

Page 5: Myofascial pain  etio pathogenesis dr rajeev harshe

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.

Page 6: Myofascial pain  etio pathogenesis dr rajeev harshe

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

Page 7: Myofascial pain  etio pathogenesis dr rajeev harshe

Injured sarcomere – improper healing—

contracted state---trigger points

Sympathetic innervation of intrafusal fibres

play role

Uncontrolled contraction—ischemia—release

of autocoids--

Page 8: Myofascial pain  etio pathogenesis dr rajeev harshe

Energy crisis theory

Muscle spindle theory

Motor end plate hypothesis

Page 9: Myofascial pain  etio pathogenesis dr rajeev harshe

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

Page 10: Myofascial pain  etio pathogenesis dr rajeev harshe

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

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
