What is Action Potential Simulation Therapy

Action Potential Simulation Therapy or APS Therapy Is a safe, effective, drug free treatment for pain relief, and to enhance recovery or injury repair and energy, using an APS Therapy machine.

This works in a unique way. APS stands for Action Potential Simulation. Action potentials are the tiny bursts of electricity that transmit information in the body, otherwise known as ‘nerve signals', and this is what the machine replicates.

Stimulates the body’s own healing mechanisms, by increasing the the production of ATP,  the molecule that creates and transports energy in the body.

Reduces inflammation and assists removal of waste products by boosting the electrical communication between cells

Reduces pain by increasing the release of neuro-transmitters involved in pain reduction

Enhances sleep by increasing production of melatonin, which aids restful sleep and wellbeing.

What conditions can be successfully treated with APS Therapy?


Many painful conditions can be treated with APS Therapy. This includes pain from injury or inflammation, arthritis, muscular pain, headaches, and in certain cases, nerve pain.


Please also have a look at the research tab above for validation studies and clinical trials.


Conditions we have successfully treated here at Painfree Potential include:


osteoarthritis, gout, carpal tunnel, elbow injury, shoulder pain, fatigue, mobility, post knee surgery pain and swelling, insomnia and sleep problems, post total knee replacement, broken bones, shoulder injuries, old car and motorbike accident injuries,  long term back pain, rheumatoid arthritis, dystonia, neuropathic pain in MS, cervical spondylosis, tennis elbow, headaches, migraine, knee pain, Achilles tendon, chronic post surgical pain and swelling, hip replacements, ankylosing spondylitis, sinus pain, sciatica, trigeminal neuralgia, occipital neuralgia, Baker’s cyst, repetitive strain injury, cramps, menstrual pain, fibromyalgia, painful psoriasis, varicose vein pain  read about people's experiences here

What treatment involves



Treatment involves sitting comfortably for around 30 minutes, and is absolutely safe and pain free.

For each different pain or problem, you follow a specific treatment plan, showing you where to apply the electrodes.

The machine is on a 8 minute timer, and we generally suggest 4 different placements of the electrodes, taking 32 minutes, each time you use the machine. It can be done when relaxing, watching TV, reading, or working at a computer.


Is APS suitable for everyone?

APS Therapy doesn’t work for every pain or everybody, and there are a few conditions where it is not safe to use APS. This is why we carry out a screening and assessment.

It’s NOT safe to use an APS machine if:

  • In the past 3 months, you have had a heart attack, pulmonary embolus, stroke or DVT
  • You have a heart pacemaker
  • You are pregnant
  • You have epilepsy
  • You have had cancer in the past 5 years
  • or small children who are too young to say what they feel

APS Therapy is not likely to help with mechanical back pain ( eg intense spinal pain when bendiing, or due to herniated disc). Some cases of sciatica have responded, and some not.

Nerve pain: We have had good success in many cases with nerve pain caused by MS, and some very successful cases with long-standing trigeminal neuralgia. However, other types of nerve pain/neuropathy, like peripheral neuropathy, small fibre neuropathy, or neuropathy due to unknown causes have not had success.

How can I try APS Therapy?


If you have pain or fatigue due to a long term condition, or chronic pain ( lasting or recurring for 3 months or more), you can trial APS Therapy with our ‘Almost-Free Trial!’


There is also a growing team of registered  APS Therapists who have been taught by Painfree Potential, across the country; see Find a practitioner if you would like one to one treatment, or for therapy centres, Find a clinic


You can also give us a call on 01908 799870 or contact us via the contact page to discuss whether APS Therapy would be appropriate, and may be able to benefit you, and how you would like to go ahead. 


When you call, your call will be taken first by our call handler, who will take your number, so that one of the team can get back to you. We look forward to speaking soon :)
