The distinction between sinusoidal current and Fradic current hinges on the unique properties of each type of electrical current, particularly concerning their penetration depth and effects on the body. Sinusoidal current is characterized by its smooth, wave-like flow, which allows for a deeper penetration into the tissue. This depth of penetration is beneficial for more extensive and effective tissue stimulation, making it commonly used in various therapeutic and aesthetic applications.

On the other hand, Fradic current, while also effective, does not penetrate as deeply. Instead, it focuses more on surface-level stimulation, which may be advantageous for certain treatments but limits its overall physiological effects compared to sinusoidal current. This understanding of sinusoidal current’s ability to reach deeper tissues elucidates why it is often preferred in situations where deeper muscle stimulation or therapeutic benefits are desired.
