Frequency-Specific Microcurrent vs. TENS Units: What's the Real Difference?
For many patients, any device that uses electrical stimulation for pain relief gets grouped into the same category. Frequency-Specific Microcurrent (FSM) devices and TENS units often appear side by side online, and both use electrodes placed on the body to deliver electrical current. At first glance, they seem remarkably similar. Both are non-invasive, used by healthcare professionals, and involve wires, pads, and electrical signals. Yet despite those similarities, FSM and TENS were developed with different goals in mind. Why Confusing the Two Can Lead to Unrealistic Expectations When patients assume that all electrical stimulation therapies work the same way, they may expect identical results from every device, which can lead to disappointment when a treatment performs differently than anticipated. Someone seeking temporary pain relief may be satisfied with a TENS unit, while a patient looking for a therapy often used in tissue recovery protocols may be directed toward FSM. Likewise,...
