What is the standard unit of measure for recording alternating current frequency in electrical stimulation treatment?

• A. Volt
• B. Hertz
• C. Coulomb
• D. Pulses per second

Answer: (B)

The standard unit of measure for recording alternating current frequency in electrical stimulation treatment is Hertz. This unit specifically denotes the number of cycles per second of a periodic phenomenon, which in the context of electrical stimulation refers to how many times the current alternates direction in one second. Understanding frequency is essential in electrical stimulation therapies, as different frequencies can elicit various physiological responses. For example, lower frequencies might be used for muscle twitch or mild contraction, while higher frequencies might be used for pain relief or muscle fatigue. Hertz provides a clear and standardized way to communicate these frequencies, ensuring consistency in treatment approaches and research applications within physical therapy and related fields. The other units mentioned have different applications: volts measure electrical potential, coulombs quantify electric charge, and pulses per second may describe the frequency of a specific type of electrical pulse but is not the standardized measure for AC frequency.
