Continuous ultrasound is characterized by a constant emission of ultrasound waves without any interruptions. This uninterrupted delivery leads to a consistent application of energy, which contributes to a thermal effect. The continuous waves penetrate the tissue and generate heat, which can promote tissue healing, increase blood flow, and relieve pain. This thermal effect is an important therapeutic advantage when using continuous ultrasound for certain conditions, as it helps increase tissue temperature and can enhance metabolic processes.

In contrast, pulsed ultrasound involves the delivery of sound waves in short bursts or pulses, alternating with periods of no emission. This intermittent application is beneficial for treatments that require a non-thermal effect, like reducing inflammation or promoting tissue repair without significant heating.

Understanding the fundamental differences between these modes is crucial in selecting the appropriate therapeutic approach depending on the desired clinical outcomes.
