Fysiio

Paper can’t move.
Video can’t turn.

Computed movement does both jobs at once — rotate it, slow it down, change the difficulty, and still hand someone a printed sheet at the end.

A real squat, computed live — not a filmed clip.

Three ways to hand someone an exercise.

We built the third column, so we judged it the same way we’d judge the other two — row by row, against what a patient actually needs. It doesn’t win everything.

Yes, we scored ourselves ✗ twice. Honest tools are easier to trust.

Keep what paper got right.

Paper doesn’t need a battery, an app, or a signal. It sits on a fridge. Nobody's ever complained that a sheet of paper was too slow to load. Those are real advantages, and we didn’t want to throw them away just because the rest of the page moves.

  • Fysiio prints too — a handout generated from the same computed movement, not a separate design.
  • Each handout carries a QR code back to the version that turns, scrubs, and adjusts difficulty.
  • Nothing about the printed sheet requires an account to make or to read.

Questions clinics actually ask

Is it medical advice?

No — it’s an educational tool. It shows a clinician-authored movement; it doesn’t diagnose, prescribe, or replace judgment made in the room.

Does the patient need an account?

No. There’s no login and no database. A program is encoded directly into the link a patient is given — open it, and it’s there.

What about the muscle data?

Clinically authored estimates, labeled as such. They’re a teaching aid for which muscles a movement targets, not a measurement of any individual patient.

See the column that does both jobs.

Browse the library the way a patient would, or look at the clinic side built for prescribing it.
