Lumbar HVLA

Question 1

What is HVLA?

Answer 1

‘Thrust techniques’ are a collection of direct method manipulative treatments that use High-velocity, low-amplitude (HVLA) activation to move a joint that is exhibiting somatic dysfunction through its restrictive barrier so that when the joint resets itself, appropriate physiologic motion is restored.”

Question 2

What causes the articular pop?

Answer 2

-no one really knows

Question 3

Does the pop actually mean anything?

Answer 3

-no pop can happen or not and still be successful

Question 4

what are some precautions and contraindications with HVLA?

Answer 4

• Vertebral basilar thrombosis
• Dens dislocation due to laxity in transverse ligament in people with RA and Conginital deformities
• pathologic fractures in metastatic or osteoporotic bone
• excessive force

Question 5

What are potential benefits of HVLA?

Answer 5

–Pain reduction
–Improved freedom of motion
–Improved biomechanical funct5ion
–Reduction of somatovisceral reflex

Question 6

Is HVLA direct?

Answer 6

yes

Question 7

What is the mechanism of joint restriction?

Answer 7

-muscles maintain joint restriction (abnormal muscle activity)

Question 8

What is the mechanism behind the thrust technique?

Answer 8

• Affects the mechanoreceptor of the joint capsule which alters the afferent output
• results in a release in muscle hypertonicity

Question 9

What must be done in order to complete this direct technique?

Answer 9

the barrier must be engaged
