What frequencies are typically used in electrical stimulation therapies?

In electrical stimulation therapies, a frequency range of 1 Hz to 1000 Hz is commonly utilized because it encompasses a broad spectrum of effects that can be achieved through electrical stimulation. Different conditions and desired outcomes call for different frequency settings. For instance, low frequencies within this range (1-10 Hz) are often associated with muscle twitch contractions and can stimulate muscle re-education and repair. As the frequency increases (20 Hz and above), the effects can shift towards pain relief and the induction of muscle tetany, which promotes muscle strength and rehabilitation.

Furthermore, frequencies above 100 Hz are often employed for their analgesic effects and are ideal for neuromuscular re-education or pain management applications, making this range quite versatile for therapeutic purposes. The upper limit of 1000 Hz also allows for integration with higher frequency electrical currents used in various stimulating applications.

Thus, the frequency range of 1 Hz to 1000 Hz provides a comprehensive framework for tailoring electrical stimulation therapies to meet a variety of clinical needs.
