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.

2
Q

With barrier mechanics, explain HVLA?

A

Move through the RB to the EB, but not through the anatomic barrier.

3
Q

Negative consequences of HVLA?

A

super low.

biggest risk is vertebral artery compromise.

4
Q

Quality of the barrier is going to feel like what?

A

firm and distinct –> mechanical type arthrodial dysfunction

5
Q

What did Dr. Nichols stress with regards to the neurophysiology of SD?

A

you have a segmental irritation that gives you edema and swelling, tighting of the components of the joint –> this leads to REFLEX HYPERTONICITY of the muscles crossing the joint –> tart changes –> SD

6
Q

Treatment mechanism of HVLA?

A

thrust through RB –> restore movement at articulation –> restore normal proprioceptive input –> reflex relaxation of muscles –> improvement of TART findings.

7
Q

what is a dysfunctional segment “not”?

A

“out of place”, or “subluxed”.

we do not adjust or put back in place.. it’s just restoring loss of motion

8
Q

Steps of HVLA summary

A

Correctly diagnose SD

Localize segment

Engage the RB in all 3 planes of motion (stacking)

release enhancing maneuver

mobilizing force - corrective thrust

reassess

9
Q

What do you do before applying HVLA principles?

A

consider applying techniques to relax overlying myofascial structures

10
Q

What are you treating during HVLA?

A

Forces are localized at the FACET JOINTS between the two vertebrae.

the part that articulates with both vertebra.

11
Q

How are you engaging the barriers?

A

forces are applied from the top down through the superior vertebrae (THROUGH THE DYSFUNCTION), and forced

forces applied from bottom up through the inferior vertebrae TO the dysfunction

12
Q

typical vertebrae (C2-L5) are assessed and treated how?

A

in 3 planes and by stacking

13
Q

Why is exhalation good for HVLA?

A

it helps for muscle relaxation

14
Q

Indications of HVLA

A

Articular somatic dysfunction

joint motion restriction with a firm articular-barrier

HVLA is effective when there is a DISTINCTIVE BARRIER WITH A FIRM END FEEL

15
Q

what should you avoid?

A

hyperextension and excessive rotation when positioning the patient.

16
Q

When would you not do HVLA?

A

EDS
Fracture
Down syndrome (maybe?)

17
Q

Absolute Contraindications of HVLA?

A

local metastases

severe osteoporosis

RA / Down syndrome (alar ligament instability)

Osteomyelitis

Joint replacement

Vertebrobasilar insufficiency

severe herniated disc with radiculopathy

fracture

spondylosis

surgical fusion

18
Q

Relative contraindications

A

Acute herniated nucleus pulposis

mild to moderate strain/sprain in area being treated

acute radiculopathy

acute whiplash/severe muscle spasm/strain/sprain

spondylolisthesis

hypermobility syndromes
