Therapeutic Ultrasound EXPLAINED | Use, Parameters, & Real Example

The video tutorial explains the use of therapeutic ultrasound in physical therapy, focusing on its thermal and non-thermal effects. It covers how to program the ultrasound machine, including duty cycle and frequency settings based on tissue depth. The tutorial also discusses attenuation coefficients and their impact on tissue heating rates. Practical application techniques, such as using ultrasound gel and moving the ultrasound head in circles, are demonstrated. The video concludes with an example of treating calf tightness using ultrasound.

What is the primary purpose of using therapeutic ultrasound in physical therapy?

• To measure blood flow

• To improve skin texture

• To diagnose bone fractures

• To relax muscles and reduce pain

What does a 100% duty cycle indicate in ultrasound therapy?

• The machine is off

• The machine is in standby mode

• The machine emits waves continuously

• The machine emits waves intermittently

Which frequency is used for treating superficial tissues with ultrasound?

• 1 megahertz

• 2 megahertz

• 3 megahertz

• 4 megahertz

What is the recommended intensity range for deep tissue ultrasound treatment?

• 3.5 to 4.0 watts per square centimeter

• 0.5 to 1.0 watts per square centimeter

• 1.5 to 2.0 watts per square centimeter

• 2.5 to 3.0 watts per square centimeter

Which tissue type has the highest attenuation coefficient, causing it to heat up the fastest?

• Bone

• Muscle

• Skin

• Fat

Why is it important to keep the ultrasound head moving during treatment?

• To prevent overheating of tissues

• To ensure the machine stays on

• To save energy

• To reduce noise from the machine

What is the effective radiating area (ERA) in ultrasound therapy?

• The region of the ultrasound head emitting waves

• The area of the skin being treated

• The size of the ultrasound machine

• The distance between the machine and the patient

What is the recommended treatment duration for ultrasound therapy?

• 11 to 15 minutes

• 1 to 2 minutes

• 3 to 4 minutes

• 5 to 10 minutes

Which of the following is NOT a suitable alternative to ultrasound for muscle tightness?

• Superficial heat

• Cold therapy

• Manual therapy

• Foam rolling

What should be checked before applying heat as an alternative to ultrasound?

• Machine calibration

• Room temperature

• Patient's age

• Presence of inflammation
