Which condition is a contraindication to HVLA (Diversified) techniques?

• A. Hypertension
• B. Osteoporosis
• C. Hypothyroidism
• D. Migraine

Answer: (B)

High-velocity, low-amplitude (HVLA) thrusts rely on the bone and joint structures staying intact under a rapid impulse. In osteoporosis, bones become fragile and can fracture even with small forces. A quick thrust during HVLA can produce compression or vertebral fracture, so this practice is contraindicated in osteoporosis. The other conditions don’t inherently prevent HVLA. Hypertension alone isn’t an absolute barrier; HVLA may be performed with appropriate assessment and precautions when blood pressure is controlled. Hypothyroidism doesn’t by itself weaken bones or joints in a way that requires ruling out HVLA. Migraine history isn’t a structural contraindication to HVLA, though clinicians may adjust care if a patient’s condition fluctuates or triggers are a concern.
