What is Frequency Specific Microcurrent (FSM) – and why are we adding it at R3 Physio?
FSM is a type of microcurrent: a very gentle, very low‑level electrical current. Most people don’t feel much, if anything, during treatment.
What makes frequency-specific microcurrent different is that we’re not just turning on a generic current and hoping for the best. We can choose very specific frequency combinations during a session based on the tissue or system we’re working with.
There are plenty of other microcurrent devices out there that use broader, general frequencies that can still be helpful. With FSM, we’re able to adapt in real time:
Select frequencies aimed at particular tissues or issues
Adjust settings during treatment based on how your body responds
Layer it into a systems‑based plan instead of using it as a random add‑on
Research on microcurrent suggests it can support ATP (cellular energy) production, tissue repair, and reduced inflammation. We treat that as one more way to help your system calm down and heal—alongside hands‑on work, movement, and everything else we already do.
If you’ve been curious what FSM actually is (beyond the buzzword), save this for when you’re ready to dig deeper.
