Return to play when the data says so.

If you keep breaking down in the same spot, the time that has passed is not the issue. We measure what is not switching back on when you move, and start again from there.

The RNO method.Five phases, from assessment to check-ups.

RNO stands for Objective Neuromuscular Reprogramming (Riprogrammazione Neuromuscolare Oggettiva). It starts with one appointment: history taking and tests on the nervous system, force and movement reveal inhibitions, compensations and asymmetries. The data becomes a programme built around you, day by day: you know what to do, why you are doing it and which factors produced an injury or are holding your performance back.

Phase 1

We listen

The first part reconstructs the full history: date and mechanism of the injury, number of recurrences, rehab programmes already completed and why they stopped.

This is not paperwork. The pattern of recurrences and the therapies that did not work tell us where to look, and they are information no instrument can record on your behalf.

Phase 2

We measure

The central part is the instrumented assessment.

Each segment is tested in isolation to obtain three parameters: peak force produced, the time needed to reach it (rate of force development) and the percentage deficit against the opposite side.

Then we move to the full movement — jump, landing, running, change of direction — recorded with surface electromyography. Compared with assessment by eye, the difference is that a compensation, a delayed activation or an asymmetry stop being an impression and become a number you can compare over time.

Phase 3

We test

One part is devoted to what instrumentation does not capture: how the nervous system behaves under load.

We place you in single-leg stance, under progressive load and in the positions your body has learned to avoid since the trauma. We are looking for a muscle that has the strength but does not receive the command to express it, an activation that cuts out when the position resembles the injury, or a co-contraction between agonists and antagonists that blocks the movement instead of producing it.

The response changes depending on where we apply the test, because the origin of the inhibition is often far from the site of pain. Ultrasound and MRI image the state of the tissue, not its ability to be recruited: that requires specific manual tests and an eye trained to recognise what the body is protecting.

Phase 4

We interpret

The final part goes to reading the results, explained without acronyms.

You see which side produces less force and by how much, which muscle activates late and in which movement, and in which positions the nervous system still protects tissue that healed months ago.

This explains why the recovery stalled without much you could do about it: it is not a question of effort, it is a neuromuscular response that had not been measured until now. You leave with your current load margins documented, a reference that does not depend on how you feel that day.

Phase 5

We rebuild

The programme is built on the values from the assessment. Every exercise has a reference parameter and a numerical target: it does not come from a standard protocol attached to that type of injury.

Every phase closes with a re-test. If the values improve, load progresses; if a parameter does not respond, the programme changes before that deficit becomes another recurrence.

The criterion for returning to play is not time elapsed, but reaching the thresholds of force, symmetry and activation that match the demands of your sport. The goal does not stop there: the load margins we work on aim past the levels you held before the injury.

The tissue has healed, the scans are clear, and yet the movement is not what it was.

After months of work, a body that will not respond wears you down more than the training does.

It is not a question of time or effort: it is a function nobody has measured yet.

Tissue heals before function does.

A time-based protocol assumes that once the expected weeks have passed, the area is ready. But when the nervous system keeps reducing activation, the available strength never reaches the movement: the load of returning to play meets the same deficit as before, and that is how a recurrence starts. Here the criterion for progression is measured neuromuscular function.

The instrument returns a number, though, not an explanation. A strength deficit in the quadriceps can originate from an ankle that has lost dorsiflexion or a hip that stopped contributing to the movement: which area to test first is a hypothesis, and what the test reveals depends on it. This is where the number of cases already seen counts, because recognising a recurring pattern narrows the field before any measurement begins. The hypothesis does not stay an opinion, however: the re-test confirms or disproves it using the same parameters.

  • Dynamography and surface electromyography: parameters recorded, not estimated by eye
  • The same tests and parameters after an injury, for prevention or for performance
  • Progression decided on force, symmetry and activation values
  • Every hypothesis about the source of a deficit is verified by re-test, not assumed

13 questions, and I already know where to start.

The questions I get most often.

What is the RNO method?

RNO stands for Objective Neuromuscular Reprogramming (Riprogrammazione Neuromuscolare Oggettiva: the acronym keeps its Italian original). It is the assessment and rehabilitation method I work with. Objective because every decision starts from a measured value (force, symmetry, activation), not from an impression or from time elapsed. It is not a one-off visit: it starts with the assessment appointment (clinical history, instrumented measurement with dynamography and surface electromyography, manual testing of how the nervous system responds under load, reading the data together), then comes the programme built on those values and the check-ups where the same parameters are measured again, to see what has taken hold and what needs correcting. It applies both after an injury and to a healthy athlete who wants to raise their performance.

What is neuromuscular rehabilitation?

It is the part of recovery that deals with how the nervous system drives the muscle, not only with how the tissue heals. After an injury, activation can stay reduced even when the structure is sound: the strength is there, but it does not reach the movement at the moment you need it. We measure that activation deficit and work to bring it back within values comparable to the healthy side and to what your sport demands.

What exactly do the tests measure?

Each segment tested in isolation gives three parameters: peak force, the time needed to reach it (rate of force development) and the percentage deficit against the opposite side. Then comes the full movement — jumping, landing, running, changing direction — recorded with surface electromyography, which shows which muscles fire, in what order and with how much delay. The result is a set of numbers you can compare over time, not a clinical impression.

How is this different from a traditional physiotherapy approach?

The difference is not the quality of the hands-on work, it is the criterion behind every decision to progress. A programme built on standard timelines advances according to the weeks since the injury; here it advances when force, symmetry and activation allow it. Measuring also means looking for the cause where the pain is not: the inhibition holding a muscle back often originates far from the symptomatic site.

Which parts of the body do you work on, and how long does the programme last?

The whole body. The principle stays the same; the tests and the reference values change with the area involved. Duration depends on the starting point — how many episodes you have had, how much deficit the assessment reveals, what your sport asks of you — so it is defined after the assessment and updated on the data from each check, not promised beforehand.

Do you only work with professionals?

Most of the people I follow are elite and professional athletes, but that is not a requirement. Anyone playing at amateur level gets the same tests, the same parameters and the same attention: what changes are the return-to-play goals, not the way of working.

How does the call work?

Fifteen minutes on the phone, free of charge. You tell me what happened, how many times it has come back and what you have already tried; I tell you whether the assessment is indicated in your case and what to expect from it. If it is not, you know that during the call itself.

Can I book the assessment on its own?

Yes, it is a service in its own right: you can stop there and use the data as you prefer, including taking it to the practitioner already treating you. You do not need to be injured — the assessment is just as useful preventively, to see whether asymmetries or activation delays are present before they turn into a problem.

Do we need to meet, or can we work remotely?

The assessment requires meeting on site, at Arcamedica (L'Aquila): force, symmetry and activation are recorded with instruments, and they cannot be measured remotely. The work that follows can partly continue online, to a degree that depends on the case: remote monitoring of the programme, with periodic check-ins on site to measure again and update the loads.

Let's talk about your case.

Fifteen minutes on the phone. You tell me what happened and what you have already tried, I tell you whether I can help. If I cannot, I will say so.
