Intro to HVLA

Question 1

define HVLA

Answer 1

rapid, brief therapeutic force that travels a short distance within anatomical range of a joint that engages the restrictive barrier to elicit release of restriction

Question 2

HVLA is also known as

Answer 2

thrust technique

Question 3

HVLA moves through what barrier

Answer 3

restrictive barrier

Question 4

quality of motion of a joint when it is brought passively to its final barrier of motion

Answer 4

end feel

Question 5

an end feel that is firm and distinct may indicate

Answer 5

mechanical type arthrodial dysfunction

Question 6

HVLA is a direct or indirect technique

Answer 6

direct

Question 7

HVLA is particularly effective when what end feel is present

Answer 7

firm end feel

Question 8

MoA for HVLA

Answer 8

thrust through restrictive barrier
resotration of motion at articulation
restoration of normal proprioceptive input

Question 9

indications for HVLA

Answer 9

quanityt + quality allow examiner to determine and define restrictions of motion
HVLA is particularly effective when there is a

Question 10

a dysfunctional segment is not subluxed, out of palce, out of joint, dislocated T/F

Answer 10

T

Question 11

steps for HVLA summary

Answer 11

diagnose SD
localize segment
engage RB in all 3 palnes of motion “stackign”
release enahncing maneuver such as breathing
mobilization force corrective thrust
resassess

Question 12

forces will be localized to what joints of vertebrae

Answer 12

facet joitns

Question 13

if force is lost before a thurst, do you continue with the treatmetn?

Answer 13

no

Question 14

dosage of HVLA

Answer 14

sicker the patient, less the dose
older the patient slower the response
most cases discourage thrusting the same segment more than once a week
if the same SD keeps occuring, evaluate and address the underlying factor

Question 15

benefits of HVLA

Answer 15

well tolerated and time efficient
modality of choice for SDs with distinct firm barrier mechanics
patietn experiences immediate releif, decreased pain and increased ROM

Question 16

safety considerations for HVLA

Answer 16

accurate dx curcial
patietns consent and comfort
listen with hands to barrier
excessive force can damamge tissue 
hypermobility of joints could be exacerbated by HVLA

Question 17

absolute contraindications

Answer 17

local metastases 
osseous or ligamentous disurption
severe osteoporosis
rheumatoid arthritis
downs syndrome due to alar ligement instability
osteomyleitis in the area being treated
joitn replacement in area to be treated
vertebrobasilar insufficnecy 
severe herniated disc wit hradiculpathy

Question 18

relative contraindictiaotns

Answer 18

apprehension by the patient
mild to moderate strain or sprains in area being treated
mild osteopenia or osteoporosis 
RA disease other than in the spine 
some hypermobile states
