Ankle sprains are the most common sporting injury and, for that reason, are one of the most treated injuries in our clinic. We all know that person; the person in our rugby league, netball team or soccer team. That person that always seems to have some sort of ankle injury. It seems as though they roll their ankle 4 or 5 times every season. Why do ankle sprains happen again and again? The short answer is that they aren’t getting rehabbed properly! The longer answer is what we will go into now.
A quick anatomy lesson - There are multiple ligaments that stabilise our ankle joint and the joints around our ankle. By far the majority of ankle injuries are those where we injure the lateral ligaments of the ankle. There are 3 ligaments on the outside (lateral side) of our ankle. They are the anterior talo-fibular ligament (ATFL), calcaneo-fibular ligament (CFL) and posterior talo-fibular ligament (PTFL). The most commonly injured are the ATFL and CFL.

As well as doing a good job at stabilising our ankle, our ligaments have tiny receptors in them which relay information to our brain to tell our brain where our foot is in space. This is why we know where our ankle is, or which way our foot is pointing with our eyes closed. This is called proprioception and is EXTREMELY IMPORTANT. The brain uses this proprioceptive input to give instructions to the muscles around our ankle and foot to keep us upright and to keep the foot stable on the ground. If we are on soft or uneven ground this becomes even more important!
When we roll our ankle and damage the ligaments on the outside of our ankle, we damage these receptors and disrupt the connection that they have with our brain. This means that our brain is getting less of this proprioceptive input so it is more difficult for it to give accurate instructions to the muscles around our ankle and foot. The muscles are also sometimes inhibited because of the pain from the injury. This reduced proprioceptive input and reduced muscle activation means that we are left with an ankle that is inherently unstable or ‘wobbly’. In the early stages, taping techniques should be utilised to protect our unstable ankle from re-injury. Further treatment should focus on restoring the stability of the ankle.

The final stage of rehabilitation following an ankle injury should focus on restoring our proprioception and ankle stability. Unfortunately this part of rehab is often ignored as symptoms have subsided and everything is feeling relatively good. If we do not restore the proprioception, or the ankle stability, we leave ourselves at increased risk of recurrent ankle sprains again and again. It is not only the ankle which is still at risk but injuries further up the chain such as the knee and hip. It is ignoring this final stage of rehab and failing to re-develop adequate proprioception and ankle stability that causes people to continually sprain and injure their ankles, even when they feel they have recovered.
An analogy that we like to use in the clinic is that of a motorbike. A motorbike has 2 wheels on the ground – we have 2 feet on the ground. Imagine if you have a motorbike where one of the wheels was wobbly – you can imagine the havoc this would cause. Our feet and ankles are no different.

About The Author
Hi! I'm Chris Slaviero
On first graduating as a physiotherapist, Chris' learning curve was immense. He had completed a degree in Sport and Exercise Science, and Nutrition in 2012, before completing his Masters of Physiotherapy at Sydney University in 2014, and the realisation quickly hits him, that there was a wide gap between the knowledge gained at university, and the knowledge and skills you required to be a great physiotherapist in private practice. Driven by this realisation, Chris strives to create the very best learning environment he can, to shape the therapists that he hires into Australia's leading private practice practitioners. This includes helping them to develop the technical skills and knowledge that is required, as well as teaching them to be the best educators and teachers they can be, to their own patients. Sport, health and fitness have always been, and continue to be, a passion of Chris'. Most people who know him are aware that he is an absolute golf tragic. His other passion is people and hearing their stories! Chris has pulled these two passions together and developed relationships with the best gyms in the Penrith area. Coming from a family of business owners, the progression from employee and mentee to employer and mentor felt a natural progression for Chris. After working at Physio Inq Glenmore Park for 3 years, Chris made the bold move of purchasing both Physio Inq Penrith and South Penrith in 2018 and hasn't looked back. Chris continues to learn as a business owner, a therapist, a mentor, and an educator, and can honestly say that he has the greatest amount of support, from the best team in the healthcare industry.
