Which ultrasound parameter set is recommended for adhesive capsulitis?

• A. 10 minutes at 3 MHz and 1.5 W/cm2
• B. 5 minutes at 1 MHz and 0.5 W/cm2
• C. 20 minutes at 5 MHz and 0.8 W/cm2
• D. 15 minutes at 1 MHz and 2.0 W/cm2

Answer: (A)

The best ultrasound set for adhesive capsulitis targets heating of the superficial tissues around the shoulder capsule to improve tissue extensibility and reduce stiffness. A higher frequency like 3 MHz heats more superficially, which suits the shoulder area where the capsule and nearby tissues are relatively close to the surface. Ten minutes at an intensity of 1.5 W/cm2 provides enough energy to raise tissue temperature to a therapeutic level without excessive heating. Other options would either risk insufficient heating (lower frequency at a shallower depth or lower intensity), heat too superficially or for too long (very high frequency with excessive duration), or use a combination that isn’t optimal for warming the shoulder capsule. This set strikes a practical balance to promote mobility and pain relief in adhesive capsulitis.
