12: HVLA Flashcards
HVLA definition
Technique employing a rapid, therapeutic force of brief duration that travels a short distance within the anatomic range of a joint that engages the restrictive barrier to elicit release of restriction
Force in HVLA
Not extreme or overpowering; use the minimum required for release of localized segment
When is HVLA most effective?
When there is a distinct barrier with a firm/hard end feel
Three benefits of HVLA
- Time efficient
- Well tolerated
- Immediate results
Most likely cause of the pop sound
Conversion of N gas in joint from liquid to gas by negative pressure
Seven steps in HVLA
- Diagnose SD
- Provide soft tissue preparation
- Localize forces to a segment or joint
- Accumulation of forces
- Release enhancing maneuver
- Corrective thrust
- Return to neutral and reassess
Examples of soft tissue preparation used before HVLA
MET, MFR, kneading, etc.
Two reasons to use soft tissue techniques before HVLA
- Relaxes and prepares physician
2. Relaxes patient, allowing more confidence + less risk of injury
How to stack restrictive barriers in HVLA
All three planes of motion are stacked to localize a joint - but dont stack restrictions in different joints
Typical release enhancing maneuver for HVLA
Patient exhalation
The corrective thrust
A short, rapid thrust in the direction of force of all vectors used for localization
Is the pop sound necessary?
No - it is not necessary for success of treatment, and it is not the goal of the treatment
How often can one thrust a segment?
Discouraged to thrust the same segment more than once a week
What can too frequent of treatment cause?
Hypermobility of segments
What to do if the same SD keeps recurring
Evaluate and address possible underlying inciting factors
