Which type of current is best suited for a nervous client?

1. Galvanic current

2. Faradic current

3. Sinusoidal current

4. High-frequency current

The correct answer is: Sinusoidal current

Sinusoidal current is particularly well suited for nervous clients due to its gentle and soothing properties. This type of current is characterized by its alternating current waveform, which allows for a more comfortable and less intense sensation compared to other forms of electrical stimulation. Sinusoidal current can effectively provide relaxation and improve muscle tone without the discomfort that can sometimes arise from more intense currents. In contrast, galvanic current involves a continuous direct current that can sometimes be perceived as more aggressive and may not be ideal for someone who is anxious or nervous. Faradic current, while beneficial for muscle stimulation, is more vigorous and can cause involuntary muscle contractions that may overwhelm a nervous client. High-frequency current, although it has numerous benefits such as antibacterial effects, can also induce a tingling sensation that might not be comfortable for those who are already on edge. Thus, the soothing and moderate effects of sinusoidal current make it the most appropriate choice for a nervous client.
