Ultraset Dosage Information

I cannot provide specific dosing recommendations for "Ultraset" as this term does not correspond to any recognized medication or therapeutic ultrasound protocol in the provided evidence or standard medical references.

Clarification Needed

If you are asking about therapeutic ultrasound dosing parameters, the evidence provides detailed guidance for musculoskeletal applications:

For Superficial Tissues (0-2 cm depth)

  • Frequency: 3 MHz 1
  • Intensity: 0.5-2.0 W/cm² 1
  • Treatment duration: 5-10 minutes 1, 2
  • Session frequency: Daily applications show benefit 3
  • Temperature goal: 1-4°C tissue temperature increase 1

Key parameters: At 3 MHz, tissue heats at approximately 0.3°C/minute at 0.5 W/cm² and 1.4°C/minute at 2.0 W/cm² 1. This frequency is optimal for superficial structures like tendons and ligaments 4.

For Deep Tissues (2-5 cm depth)

  • Frequency: 1 MHz 1, 5
  • Intensity: 0.5-2.0 W/cm² 1
  • Treatment duration: 5-10 minutes 1
  • Session frequency: Daily applications 3
  • Temperature goal: 1-4°C tissue temperature increase 1

Key parameters: At 1 MHz, tissue heats at approximately 0.04°C/minute at 0.5 W/cm² and 0.38°C/minute at 2.0 W/cm² 1. Despite conventional teaching, depth of heating does not significantly vary with frequency changes between 0.86-3 MHz 5.

Important Clinical Considerations

Equipment requirements: High-frequency linear transducers (7.5-20 MHz) for superficial structures; lower frequency transducers (3.5-5 MHz) for deeper joints 4.

Safety parameters: The thermal index should not exceed 1.0, indicating tissue temperature should not increase more than 1°C above physiological levels for sensitive tissues 6.

Common pitfall: When applying ultrasound underwater, significant dosage corrections are required—increasing distance from 0 to 4 cm requires substantial intensity increases to maintain equivalent tissue heating 2.

If "Ultraset" refers to a specific combination medication (such as tramadol/acetaminophen), please clarify so I can provide appropriate dosing guidance.
