What are the primary parameters adjusted in electrical stimulation therapy?

• A. Voltage, frequency, and amplitude
• B. Frequency, intensity, and pulse duration
• C. Resistance, impedance, and capacitance
• D. Current, resistance, and power

Answer: (B)

In electrical stimulation therapy, the primary parameters adjusted to achieve effective treatment outcomes are frequency, intensity, and pulse duration. Frequency refers to how many times the current pulses occur in one second, which can affect muscle contractions and the type of stimulation experienced by the patient. Higher frequencies can lead to muscle tetany, while lower frequencies might produce a more rhythmic contraction. Intensity, often synonymous with amplitude in the context of stimulation, determines the strength or depth of the stimulation. Adjusting intensity allows practitioners to tailor the sensation of the stimulation based on the patient’s tolerance and therapeutic needs. Pulse duration is the length of time each pulse lasts. This parameter influences the strength of the muscle response and can be adjusted to avoid discomfort or to achieve desired therapeutic outcomes. Together, these three parameters allow for a customized approach to electrical stimulation therapy, facilitating better management of pain relief and muscle rehabilitation. The other options include terms that, while important in electrical principles, are not the primary focus in the context of electrical stimulation therapy.
