Innovation of Compex for Muscle Stimulation.

Compex Innovation Spotlight: How Mi-Scan Revolutionizes Muscle Stimulation

If you’ve ever used an electrostimulation device like the Compex SP or Wireless series, you know that getting the settings right can make the difference between an effective session and one that feels uncomfortable or underwhelming. Too little intensity and you’re not recruiting enough muscle fibers; too much and you’re gritting your teeth instead of training.

That’s exactly the problem Compex solved with Mi-Scan – a clever piece of technology built into their premium devices that takes the guesswork out of personalization.

What is Mi-Scan and how does it work?

Mi-Scan (Muscle Intelligence Scan) is an intelligent sensor system integrated into each electrode of compatible Compex devices. Before your session starts, the device sends a low-intensity test signal through the muscle and measures three key physiological parameters in just a few seconds:

Muscle excitability (how easily your muscle responds to stimulation)
Chronaxie (the pulse duration your muscle prefers)
I/T curve (the relationship between current intensity and muscle contraction)

Using these real-time readings, the Compex unit automatically adjusts the stimulation parameters – pulse width, frequency, and the ideal intensity ramp – to match your specific muscle characteristics at that exact moment.

Why this matters

Your muscles aren’t static. Fatigue, hydration, temperature, electrode placement, and even the time of day affect how they respond to electrical stimulation. What felt perfect last week might feel too strong or too weak today.

Mi-Scan adapts every single session to your current physiology, ensuring:

Maximum muscle fiber recruitment without excessive discomfort
More efficient workouts and recovery sessions
Consistent results even when you’re tired or conditions change
Faster progression because the device is always “dialed in”

Real-world difference

Athletes who switch from a standard Compex program to one using Mi-Scan typically report being able to tolerate (and benefit from) higher intensities comfortably. That translates directly into better strength gains, improved endurance, and faster recovery – all because the stimulation is truly personalized.

Which Compex models include Mi-Scan?

You’ll find Mi-Scan technology in the higher-end wired and wireless lines:

Compex SP range

Just look for the “Mi” logo on the electrodes – that’s your sign the smart scanning is active.

Mi-Scan turns a good stim device into a genuinely personalized training partner. In under 10 seconds, it reads your muscle like a fingerprint and tailors the entire session accordingly.

For serious athletes, coaches, and physios who want every rep – electrical or otherwise – to count, it’s one of those small innovations that delivers outsized results.
