Lecture 3: Intro to HVLA Flashcards

1
Q

What is the definition of HVLA?

A

Rapid, therapeutic force of brief duration that travels a short distance within the anatomic range of a joint and that engages the restrictive barrier to elicit release of restriction

A

Localize to the RB and then move through RB into the PB

Q

What is End feel; when would you feel firm and distinct?

A
  • Quality of a joint when it is brough passively to its final barrier of motion
  • Firm and distinct = typically mechanical type arthroidal dysfunction

Q

What are indications for HVLA; what type of end feel is best?

A
  • Quantity + Quality allow examiner to determine and define restriction of motion
  • HVLA is particularly effective when there is a distinctive barrier w/ a firm end feel

Q

What is the first step of HVLA, the intial positon?

A
  • Crucial for Physician AND patient to be in comfortable position
  • Consider applying techniques to relax overlying myofascial structures (ST, BLT, MFR).

Q

Engagement and stacking of barriers for HVLA; you will treat an L3 SD as it articulates with ____?

Q

When engaging and stacking barriers the forces are applied from the top down _______ the dysfunction; or from the bottom up ________ the dysfunction?

A
  • Top down through the superior vertebra
  • Bottom up through the inferior vertebra to the dysfunction

16
Q

When stacking barriers and using HVLA the other vertebra of the unit (not the dysfunctional one) is used as?

A

An opposing counterforce

17
Q

Typical vertebra (C2-L5) assessed and treated in how many planes of motion?

A
  • 3 planes of motion
  • HVLA is utilized by stacking RBs in all 3 planes
18
Q

Appendicular restriction - typically restricted in one Major and an associated minor motion, which is the focus of HVLA?

A

Typically focuses on the minor joint motion restriction

19
Q

What is absolutely critical of the engaging force once all RBs are stacked?

A

Must be maintained; if force is lost DON’T THRUST!

20
Q

What will give the most effective thrust?

A
  • Don’t release force prior to thrust
  • Exhalation –> muscle relaxation –> more effective thrust
21
Q

What are the 6 correct steps for HVLA?

A
  1. Correctly diagnose SD
  2. Localize segment
  3. Engafe the RB in all 3 planes of motion - stacking
  4. Release enhancing maneuever (patient breathing)
  5. Mobilizing force - Corrective thrust
  6. Reassess
22
Q

What are the general rules for dosage of HVLA?

A
  • Sicker the patient, less the dose
  • Older patients respond more slowly
  • Most cases discourage thrusting the same segment more than once a week
  • If the same SD keeps recurring, evaluate and address for underlying inciting factors
23
Q

Benefits of HVLA?

A
  • Well tolerated and time efficient
  • Modality of choice for SDs w/ distinct firm barrier mechanics (arthroidal types)
  • Patient typically experiences immediate relief, decreased pain, and increased ROM
24
Q

Absolute contraindications for HVLA?

A
  • Local Metastases
  • Osseous or ligamentous disruption
  • Severe osteoporosis
  • Rheumatoid Arthritis

- Down syndrome

  • Osteomyelitis in the area being treated
  • Joint replacement in the area being treated
  • Vertebrobasilar insufficiency
  • Severe herniated disc w/ radiculopathy
25
Q

Why are Rheumatoid Arthritis and Down Syndrome absolute contraindications for HVLA?

A

Both associated w/ Alar ligament instability

26
Q

What are the relative contraindications for HVLA?

A
  • Apprehension by the patient
  • Mild to moderate strain or sprain in area being treated
  • Mild osteopenia or osteoporosis
  • RA disease other than in the spine (arthritis)
  • Some hypermobile states
