What is the recommended ultrasound output for chronic conditions?

The recommended ultrasound output for chronic conditions is characterized by the use of continuous ultrasound. Continuous ultrasound can provide a deeper and more consistent heating effect, which is beneficial for treating chronic conditions where increased tissue temperature and blood flow are desired for improved healing. The output level reaching up to 1.5 W/cm² allows for effective treatment while minimizing the risk of overheating surrounding tissues.

In contrast, other modalities mentioned do not align with the specific needs for chronic conditions. For example, using intermittent modes, while useful in acute scenarios to prevent overheating and to facilitate tissue repair, does not provide the same sustained thermal effects required in chronic conditions. Similarly, an output rating of up to 1.0 W/cm² might be too low to achieve the therapeutic effects necessary for effective treatment in such situations. The emphasis on using a continuous mode allows clinicians to harness the full benefits of thermal ultrasound therapy.
