Joint Mobilisation

Question 1

Passive Joint Mobilisation

Answer 1

“A therapist applied technique that uses oscillations of joint movement to increase range of movement, reduce pain, or improve altered quality of movement.”

– Physiological joint motion are movements we can do voluntarily (flexion &
extension)
– Accessory movement are movements necessary for normal joint motion, but cannot be voluntarily performed or controlled (slide, roll, spin)

Question 2

How does passive joint mobilisation work

Answer 2

How does passive joint mobilisation work?
* Facilitate the gait-control mechanism
* Oscillations stimulate mechanoreceptors that inhibits transmission of nociceptive stimulation from spinal cord & brain stem
* Affect muscle spasm & guarding
Inhibition of nociceptive stimulation which promotes muscle relaxation

Question 3

5 grades of movement

Answer 3

· Grade 1- small amplitude at the beginning of range, no resistance
· Grade 2- large amplitude within resistance free range, no resistance
· Grade 3- large amplitude into resistance, goes past R1 to the point of R2
· Grade 4- small amplitude into resistance -begins at R1 into R2
Grade 5- manipulation, small amplitude thrust beyond R2 - performed at the end of available range

Question 4

when for what grades

Answer 4

Grade I & II
– Used to reduce joint pain
– Grade I & II oscillations stimulate joint mechano-receptors to inhibit nociceptive feedback to the joint
– Can be used before Rx to relax joint
– Can be used after Rx to relieve any discomfort caused by Grade III & IV mobes  Grade III & IV
– Used gain joint range of motion
– Stretch joint capsule and connective tissue structures limiting joint mobilit
