Q

What is the definition of HVLA?

A

thrusting technique

employs a rapid, therapeutic force of brief duration that travels a short distance w/ in anatomic range of a joint & engages the restrictive barrier to elicit release

Q

Mechanism of treatment w/ HVLA

A

thrust thru restrictive barrier

restoration of motion @ articulation

restoration of normal proprioceptive input

reflex relaxation of muscles

improve TART findings

Q

What is the barrier positioning in HLVA?

A

localize firmly against restrictive barrier

moves thru restrictive barrier into elastic barrier to restore motion

16
Q

What is the goal of OMT?

A

restore or augment tissue function

17
Q

Steps for HVLA

A

diagnose SD

provide soft tissue prep

localize force to segment or joint

release enhancing maneuver

accumulation of forces

corrective thrust

return to neutral

reassess

18
Q

What is the purpose of soft tissue preparation?

A

reduces risk of soft tissue injury

increases pt confidence in physician

19
Q

Why should physician be relaxed during HVLA?

A

free up cortex to receive kinesthetic input from hands & fingers (can think about what you are feeling more)

relaxed muscles better for rapid contraction

20
Q

Why should pt be relaxed during HVLA?

A

muscle relax prevents tensing that can interfere w/ correction

reduces risk of muscle or tendon injury

21
Q

What is localization of HVLA?

A

engagement & stacking of barriers

22
Q

Where can you treat in all 3 planes of motion?

A

the spine

23
Q

Where is the HVLA force localized on vertebrae?

A

forces localized to facet joints between 2 vertebrae (L3 SD on L4)

24
Q

What occurs during accumulation of forces?

A

move firmly against barrier on pt exhalation

25
Q

When should you not continue to thrust?

A

if localization to barrier in 1 of the planes is lost

26
Q

What is the direction of your thrust?

A

towards the culmination of all planes of motion

27
Q

What are the general rules regarding OMT dosage?

A

more acute or sick, less the dose

older pts respond more slowly

usually do not thrust the same segment more than once a week

decrease treatment as pt improvement duration increases

28
Q

Benefits of HVLA

A

time efficient

well tolerated

pt usually experiences immediate relief, decreased pain & increased ROM

29
Q

Indications for HVLA

A

SD
articular SD
joint motion restriction

30
Q

When is HVLA super helpful?

A

adhesive capsulitis

chronic dysfunction

modify reflexes

hypomobile joints

restore alignment

reduce meniscus entrapment

pain modulation

31
Q

What is significant about OMT safety & efficacy?

A

OMT is one of safest procedures in medicine

32
Q

How to minimize injury w/ HVLA?

A

take thorough history
careful PE
use minimal amt of force

33
Q

What is a major precaution for cervical spine?

A

avoid hyperextension & excessive rotation

34
Q

“Absolute” contraindications for HVLA

A
local cancer
ligament disruption
RA
Down Syndrome
Osteomyelitis
Spinal cord Dx
35
Q

What is the most important absolute contraindication for OMT/HVLA?

A

pt refusal

36
Q

What are relative contraindications for HVLA?

A
acute herniated nucleus pulposus
acute radiculopathy
acute injury
osteoporosis
spondylolisthesis
metabolic bone disease
hypermobile syndromes
37
Q

What are some precautions for HVLA?

A

apprehension by pt

mild to moderate strain or sprain in area being treated

38
Q

When would you avoid compression?

A

mild osteopenia or osteoporosis
