What type of waveform is commonly used in electrical stimulation therapy?

Pulsed waveforms are commonly used in electrical stimulation therapy because they offer a range of benefits that can effectively cater to therapeutic needs. Unlike continuous waveforms, pulsed waveforms deliver bursts of electrical energy at specific intervals, which can minimize discomfort and allow for better control of muscle contractions. This pulsed application can lead to effective muscle stimulation for rehabilitation and pain relief by targeting specific nerve pathways without overwhelming the tissue.

Pulsed waveforms can also be adjusted in terms of frequency, duration, and intensity, offering flexibility in treatment strategies for different patients and conditions. This adaptability is crucial in therapeutic settings, where the goal is often to stimulate healing or alleviate pain without causing excessive strain or discomfort.

Other waveform types, such as sine, square, or continuous waveforms, may have specialized uses in different contexts but are not as prevalent for general therapeutic electrical stimulation. Sine waveforms, for example, are typically associated with more continuous forms of stimulation, while square waveforms might be used in certain applications but lack the fine-tuning that pulsed waveforms offer for therapeutic purposes.
