What does therapeutic ultrasound use to promote tissue healing?

Therapeutic ultrasound uses sound waves to promote tissue healing. The principles behind this modality involve the generation of high-frequency sound waves that penetrate the tissue, leading to effective thermal and non-thermal effects. These sound waves increase the temperature of the tissue and enhance blood flow, which aids in the healing process by delivering more oxygen and nutrients to the area while also facilitating the removal of waste products.

Additionally, ultrasound can help to break down scar tissue and improve the elasticity of connective tissues, making it a valuable tool in physical therapy for conditions such as tendinitis, muscle strains, and joint injuries. The specific frequencies and intensities of ultrasound can be adjusted depending on the treatment goals and the type of tissue being targeted, enhancing its versatility in therapeutic applications. This understanding of how therapeutic ultrasound works is key for any aspiring physical therapy technician in their practice.
