How
20-50% pressure
Resist for 10s
Stretch for 15-25s- during refractory period
Aiming to regain normal ROM not inc flexibility
Normal bind
Progressive tension build up, fluid= dec ROM, spongy
Physiological bind
End point= tight + tugging
Fibrotic bind
Quick + harsh- still remains elastic
Hypermobile bind
Loose and inc ROM
Bony tissue bind
Reduced ROM, sudden + hard
Contraindications
Open wounds
Fractures
Physiology
Contraction triggers Golgi tendon
Afferent impulse to dorsal root of spinal cord
Meets inhibitory motor neurone to prevent further contraction
Muscle tone decreases, resulting in agonist relaxing + lengthening
