22
Q

What is a grade I accessory movement?

A

small amplitude movement at the beginning of the available ROM

23
Q

What is a grade I accessory movement used for? How does it work?

A

Pain - Activates mechanoreceptors in the SUPERFICIAL layer of the joint capsule
- Acts via pain-gate mechanism
o Stimulation of mechanoreceptors causes transmission via A beta fibres – help to close the pain gate and reduce transmission via A delta and C nociceptive fibres

24
Q

What is a grade II accessory movement?

A

large amplitude movement at within the available range of movement

25
Q

What is a grade II accessory movement used for? How does it work?

A

Pain - Activates mechanoreceptors in the DEEP layer of the joint capsule
- Acts via pain-gate mechanism
o Stimulation of mechanoreceptors causes transmission via A beta fibres – help to close the pain gate and reduce transmission via A delta and C nociceptive fibres

26
Q

What is a grade III accessory movement?

A

large amplitude movement that moves into stiffness or muscle spasm

27
Q

What is a grade III accessory movement used for? How does it work?

A

Stiffness - Stretching the tissues into the plastic range – causes breaking of cross links within the collagen and help to increase extensibility
- Mainly stretches the joint capsule

28
Q

What is a grade IV accessory movement?

A

small amplitude movement stretching into stiffness or muscle spasm

29
Q

What is a grade IV accessory movement used for? How does it work?

A
  • Stretching the tissues into the plastic range – causes breaking of cross links within the collagen and help to increase extensibility
  • Can be used if patient does not tolerate grade III, since although it is further into resistance, it is lower amplitude
30
Q

What is the concave-convex rule?

A

Concave surface moving on convex surface, so lever moves in the SAME direction as the glide

Convex surface moving on concave surface, so lever moves in the OPPOSITE direction to the glide
