os final Flashcards
What was the major OMT technique taught prior to the 1970s?
HVLA
HLVA employs a ___, therapeutic force of brief duration that travels a ____ within the anatomic range of a joint and that engages the restrictive barrier to elicit release of restriction
rapid, short distance
HVLA employs a rapid, therapeutic force of brief duration that travels a short distance within the ____ of a joint and that engages the _____ to elicit release of restriction
anatomic range, restrictive barrier
physiologic barrier - end ROM achieved during ____ motion in the absence of SD
active
anatomic barrier - end ROM achieved during ___ motion in the absence of SD
passive
restrictive barrier is a functional limit that abnormally diminishes the normal ____ range
physiologic
When is cervical HVLA contraindicated?
if the vertebral artery is occluded by thrombosis/compromised
What three planes of motion is range of motion measured in?
mid-sagittal, coronal and transverse
quality refers to?
a palpatory sense of how smoothly a joint can be moved through its ROM
end feel refers to
a quality of motion of a joint when it is brought passively to its final barrier of motion
What is a firm and distinct end feel?
mechanical type arthroidal dysfunction
When is HVLA particularly effective (regarding measuring ROM)?
when there is a distinctive barrier with a firm end feel
What is the neurophysiology of HVLA? 5 steps
- thrust through the restrictive barrier
- restoration of motion at articulation
- restoration of normal proprioceptive input
- reflex relaxation of muscles
- improvement of TART findings
True or false: joint noise is necessary for successful treatment
false
True or false: osteopathic physicians adjust/put segments back into place
false
What is the goal of OMT in regards to the mechanism of treatment?
to restore motion loss and restore neutral point back to normal
What are the 6 steps to HVLA?
- Correctly diagnose SD
- localize segment
- engage the RB in all 3 planes of motion - stacking
- release enhancing maneuver (breathing)
- mobilizing force -corrective thrust
- reassess
What does a vertebral unit consist of?
two adjacent vertebrae with their associated disc, arthroidal , ligamentous, muscular, vascular, lymphatic and neural components
Where are the forces localized at a vertebral unit?
facet joints
What are the benefits of HVLA?
- its well tolerated and efficient
- modality of choice for SDs with distinct firm barrier
- patient feels immediate relief, decreased pain and increased ROM
what are the indications for HLVA?
- articular somatic dysfunction
- joint motion restriction with a firm articular barrier
is HVLA a safe treatment option?
yes
what do you avoid when addressing the cervical spine?
avoid hyperextension and excessive rotation when positioning the patient
what are the two main absolute contraindications of HVLA?
rheumatoid arthritis and down syndrome because of alar ligament instability
