The art of the sprained ankle

The art of the problem sprained ankle
A common clinical presentation is a patient with a 3 month (or thereabouts) history of an inversion ankle sprain, with persisting symptoms of pain and swelling and reports of altered function. We think it is so common, that in many cases it is not even clinical – i.e. that person has not bothered to turn into a patient. Using the world of clinical experience, backed by some neuroscience, here is how to help the patient or person fix most of these problems.

The problem ankle findings
On the problem foot, there may be a slight range limitation and symptoms evoked on plantar flexion and inversion. ‘Giving way’ is common. The ankle probably still has some pitting oedema. On the neurodynamic test for the fibular (peroneal) nerve (ankle plantar flexion and inversion plus SLR) symptoms are typically worsened with pains and pullings along the peroneal tract at around 40 degrees. Frequently, there are limitations in the tests of sural (dorsiflexion and inversion and SLR) and the tibial (dorsiflexion and eversion plus SLR). On the other ‘good’ side, symptoms are much less and the range considerably higher.

How to fix – five key points
These ankles are easy to manage and are very appropriate for self management.

1. Tell the ankle owner (AO) and anyone else interested, what is probably happening. That a peripheral nerve is a bit irritated and sticky in the swelling and maybe it has had a slight sprain as well. That an ankle sprain is no insignificant event and a bit of swelling and pain is normal as the brain tries to fix the final few problems. Tell them there are little sensors in nerves and they report the chemicals, the pulls and pressures and even stress and temperature. These calm down when the brain is satisfied that the ankle is OK. Tell them that the whole central nervous system is aware of the ankle and keeping an eye on it and that’s why all ankle movement may hurt a bit. But make sure they know its all good and normal and a part of the healing process in a healthy individual. In fact they should be proud of their nervous system for looking after them, but it needs a bit of advice. Check and tell them the ankle is stable but sensitive.

2. Tease and wriggle the peroneal and other appropriate nerves. Find three or four ways to wriggle the nerves, for example, the technique shown below (easy to do actively) or others in ‘The Sensitive Nervous System’ or the “DVD handbook”. Wriggle in and out of some discomfort as long as the ankle owner knows that it is a good pain – maybe 6 times a day with 20 or so mobilizations until you come to an ideal baseline. It won’t need much.

3. Keep up the graded proprioceptive input. Wobble boards are OK but we don’t use wobble boards in everyday life. Walk on uneven surfaces, rocks etc. Let the ankle reconstruct its role in the brain by reducing fear of use.

4. Most ankles will improve in a few days with range restored in perhaps 2 weeks or less. Much of it can be done actively. Wriggle it into a little bit of pain if the owner understands that it is an OK pain. The ultimate ankle technique will be to take up the ankle movements first, then SLR and then wriggle the ankle.

5. But the brain won’t forget. These are novel movements superimposed on a disturbing injury. It is likely, even normal, that there will be a response of increased pain, even some swelling and perhaps disturbed sleep during the treatments. Movement improvements will usually still be obvious. No panicking please– tell the AO that it is normal, its the brain checking out what is happening and probably creating a bit of a response to seek more input and knowledge on which to base actions. And at the ankle itself there is a bit of excitement with the refreshment of new tissue movement as the sensors adjust. It’s all good – these ‘flare-ups’ will only last a day or so.

Your turn
Send us your clinical experiences of simple neural mobilisation rapidly helping a problem such as the persistent ankle. A Neurodynamics pack will be sent to the person with the best answer.

Graded motor imagery 101
Take a crash course in Graded Motor Imagery by watching and listening to David Butler give a 40 minute presentation at the recent Denmark Fysioterapeuten Conference. It’s a very valuable resource for clinicians and also particularly beneficial for patients who can develop an understanding about what their rehabilitation process is based upon.

Comprehensive one-day Graded Motor Imagery courses are now available in the United Kingdom.

NOI goes to Brazil
With a rockstar reception and a constant shake of his hips, David Butler has been teaching Mobilisation of the Nervous System and Explain Pain courses in São Paulo, Brazil as NOI released the Explicando A Dor book (Explain Pain) for the Portuguese speakers.
