Which of these is NOT typically treated with sinusoidal current?

Sinusoidal current is a type of alternating current used in various beauty and therapeutic treatments, particularly in the fields of esthetics and physical therapy. Its primary benefits include stimulating muscle contractions, improving circulation, and facilitating the absorption of products.

The chest area is not typically treated with sinusoidal current due to safety concerns and the lack of common applications for this area in esthetics. The chest houses vital organs, and any treatment in this vicinity must be approached with caution to avoid any potential complications or health risks.

In contrast, treatments on the face, scalp, and hands often utilize sinusoidal current because these areas can benefit significantly from the stimulation of muscles and blood supply. The face may be treated for muscle toning and firming, the scalp for stimulating hair follicles and enhancing growth, and the hands for improving circulation and skin health.
