Ultrasound indications include treatment of plantar warts.

• A. Plantar warts
• B. Osteoarthritis
• C. Hypertension
• D. Brain tumor

Answer: (A)

Therapeutic ultrasound is used to promote tissue healing and pain relief by heating tissues and increasing local circulation, and it can be used to aid other skin treatments as well. Plantar warts are often treated with keratolytics and procedures that rely on softening the thick, keratinized skin of the wart; ultrasound can help soften this surface and may improve the effectiveness of topical treatments or disruption of the lesion. The other conditions listed don’t fit as primary ultrasound indications in this context: osteoarthritis may be managed with ultrasound for symptomatic relief, but it’s not a primary indication; hypertension and brain tumors are systemic issues unrelated to ultrasound therapy.
