Why is it important to use the lowest intensity of ultrasound that achieves the desired effect?

Using the lowest intensity of ultrasound that achieves the desired therapeutic effect is crucial primarily to prevent overheating of tissues. Ultrasound therapy relies on sound waves to produce a therapeutic effect, and higher intensities can lead to excessive heat generation in biological tissues. This overheating can cause discomfort or even damage to the tissues being treated.

By selecting a lower intensity, practitioners can minimize the risk of thermal injuries while still providing effective treatment. This approach is particularly important in sensitive areas or when treating patients who may have underlying conditions that make them more susceptible to heat-related injuries. It ensures that the therapy is both safe and effective, promoting healing without adverse effects.

While improving therapy duration, enhancing the clarity of the waves, and avoiding interruptions are relevant concepts in ultrasound therapy, the primary concern when adjusting intensity is to protect the tissue from overheating.
