Lesson Objectives

1. Describe how sound energy is transmitted through the body
2. Define treatment parameters and units of measure used in ultrasound: (frequency, duty cycle, intensity).
3. Describe the non-thermal effects of therapeutic ultrasound.
4. Select continuous vs. pulsed ultrasound based on the intended tissue effect in a patient case scenario.
5. Differentiate between absorption and penetration effects of ultrasound in soft tissue.
6. Differentiate between reflection and refraction effects of ultrasound in soft tissue.
7. Describe how the anatomy underlying tissues effects impedance and absorption of ultrasound.
8. Define "unstable cavitation" and what a PTA can do to prevent it.
9. Explain why understanding cardinal signs of inflammation is important in selecting and applying ultrasound.
10. Explain why a coupling agent is recommended when administering ultrasound.
11. Select an appropriate response if a patient reports pain during ultrasound application.
12. Identify the role of the PTA during application of physical therapy interventions covered in this course.
13. Discuss how the patient's age and medical status may influence selection and outcome of treatments with physical agents.
