What are non-thermal ultrasound indications primarily focused on?

Non-thermal ultrasound is primarily utilized for the promotion of healing during the acute phase of injury. This type of ultrasound operates at settings that do not generate significant heat but instead leverage mechanical effects, such as cavitation and acoustic streaming. The mechanical waves facilitate various physiological processes, including the mobilization of fluid and enhancement of cellular activities that support tissue repair and regeneration.

During the acute phase of injury, the focus is on minimizing further damage and initiating the healing response. Non-thermal ultrasound achieves this by improving circulation and reducing edema, which can be particularly beneficial right after injuries such as sprains or strains. By stimulating cellular activity and enhancing the healing process without the risk of further thermal injury, non-thermal ultrasound has a significant role in rehabilitation and recovery strategies.

In contrast, other choices like heating tissue or stretching connective tissue are associated more with thermal ultrasound applications, where temperature increases can lead to tissue extensibility. Reducing inflammation, while a beneficial effect of healing, encompasses various modalities and is not solely linked to the use of non-thermal ultrasound as its primary indication.
