Principles

HVLA applies a short, controlled thrust at the end of the restrictive barrier. The joint is positioned to localize forces and eliminate adjacent compensatory motion, often called stacking or locking.

Setup and Safety

  • Explain the technique and obtain consent.
  • Position the patient comfortably with the joint at the restrictive barrier.
  • Use your body mechanics to generate a quick, low-amplitude impulse.
  • Reassess motion after the thrust.

Contraindications

Absolute / strong relativeExamples
Bone diseaseOsteoporosis, osteopenia with fragility, Paget disease
MalignancyMetastatic cancer involving bone
TraumaAcute fracture, dislocation, severe sprain
NeurovascularUnstable cervical artery disease, myelopathy
InfectionOsteomyelitis, septic arthritis

Cervical HVLA carries additional risk; screen for vertebral artery insufficiency and avoid if cervical instability is suspected.

Q: What is the defining feature of HVLA?

A: A rapid, low-amplitude thrust applied through a restrictive barrier.

Q: Why is osteoporosis a contraindication to HVLA?

A: Reduced bone density increases fracture risk under thrust forces.
