Final answer:
The primary treatment goals when applying US treatment parameters based on a desired 4-degree tissue temperature increase are to reduce muscle spasm, increase collagen extensibility, and increase blood flow.
Step-by-step explanation:
The primary treatment goals when applying US treatment parameters based on a desired 4-degree tissue temperature increase are to reduce muscle spasm, increase collagen extensibility, and increase blood flow.
- Reduce muscle spasm: The heat generated by ultrasound diathermy helps relax muscle fibers and decrease muscle spasm.
- Increase collagen extensibility: Ultrasound treatment can promote the stretching and realignment of collagen fibers, thus increasing their extensibility.
- Increase blood flow: Ultrasound diathermy increases blood flow to the treated area, which can aid in the healing process.
