Flashcards in Chapter 16 HVLA Basics Deck (11):
1

What type of technique is HVLA?

Passive direct

2

Theories of the neurophysiology of HVLA?

1) Forcefully stretching a contracted muscle sends a barrage of afferents to CNS, causes reflex inhibitory signals to the spindles
2) Forcefully stretching contracted muscle activates the golgi tendon and reflexively relaxes muscle

3

When is the final force applied?

Relaxation/exhalation phase

4

What is the main indication of HVLA?

Motion loss in somatic dysfunction

5

What are the absolute contraindications?

1) Osteoporosis
2) Osteomyelitis (including Pott's)
3) Fractures in area of thrust
4) Bone mets
5) Severe RA
6) Down's

6

Why are RA pts at risk?

RA weakens the transverse ligament of the dens, so cervical manipulation may cause AA subluxation

7

Why are Down's pts at risk?

Laxity in transverse ligament of dens may results in AA subluxation with cervical manipulation

8

What are the relative contraindications?

1) Acute whiplash
2) Pregnancy
3) Post-op conditions
4) Herniated nucleus pulposus
5) Pt's on anticoagulaion or hemophiliacs
6) Vertebral artery ischemia (positive Wallenberg's test)

9

What is the most common MINOR complication?

Soreness or symptom exacerbation

10

What is the most common MAJOR complication overall?

Vertebral artery injury--usually due to cervical rotatory forces with neck in extended position

11

What is the most common MAJOR complication in the low back?

Cauda equina syndrome (very rare)
