Specialist FES cycling, since 2003
FES Cycling
and much more.
Functional Electrical Stimulation cycling uses small electrical impulses to activate paralysed or weakened leg muscles, so you can pedal a stationary bike and get active exercise. Until now, this meant buying a complete system built for that one purpose. PAJUNK® Stim2Go changes that. It pairs with almost any cycle ergometer, works standalone for functional training, and supports tSCS protocols. All controlled through an app that keeps the device up to date as the evidence evolves.

The technology, briefly
What FES cycling actually does.
Paralysis or weakness due to a neurological condition limits the active exercise we can participate in. FES uses small, programmed electrical impulses to activate paralysed or weakened muscles, producing co-ordinated movement on a stationary bike. Regular FES cycling has been demonstrated by extensive research to support cardiovascular health, muscle mass, bone density, and circulation.
The evidence is strongest for people who maintain a consistent programme over months and years. The honest summary: outcomes vary between individuals, but the trajectory for those who stay with it is positive.
Who we work with
Conditions we support.
FES cycling can support people across a range of neurological conditions. Every situation is different. We help you understand what is realistic for you.

The people behind it
It is not just the device.
It is who sets it up.
When you invest in a medical device, what often matters most is what happens after the purchase. Who assesses your situation. Who sets it up in your home. Who picks up the phone when something is not right. For FES cycling in the UK, that is us. We have been doing this work for over twenty years, and we still answer the phone ourselves.
Whatever your condition and wherever you are in your journey, there is always reason to pursue better health. The right knowledge, the right technology, and the right support can make a meaningful difference.

One Stimulator Across the Caseload: The Case for Consolidating Modalities
Most clinics accumulate single-purpose stimulators over time, one per modality. A device that consolidates FES, NMES, TENS and tSCS into one body-worn unit changes the equipment conversation from replacing capacity to broadening it. Here is the practical case, and its limits.

Spasticity as the Rate-Limiting Step: Sequencing tSCS and Functional Practice
When spasticity is the factor blocking a functional task, the question is not which modality but in what order. This article sets out the case for priming with tSCS, then practising the task with triggered NMES, on a single device.

Triggered Stimulation for Sit-to-Stand: Putting the Stim2Go to Work Beyond the Bike
Most clinicians meet the Stim2Go as an FES cycling stimulator. The same body-worn unit, with the same motion sensing, is well suited to triggered NMES for sit-to-stand and other functional tasks. This article sets out how to think about that, and how to set it up.

Pairing FES cycling with the right spinal stimulation waveform
A new mechanism paper sharpens an underdiscussed question for FES cyclists adding transcutaneous spinal stimulation: the waveform you choose determines whether you are priming the spinal cord or just adding a second source of motor stimulation.

The Cauda Equina Question: Why FES Cycling Will Not Help You, and What Will
If you have a cauda equina or conus injury, the FES cycling literature does not really apply to you. The good news is that there is a different kind of stimulation that does, and most UK readers have never been told about it.
