22 Sep Ankle Sprains: Causes, Rehab, and Treatment Strategies
Just sprained your ankle? You’re not alone. Ankle sprains are the most common lower-body injury in all of the sports, so if you’re one of the few that has never experienced an ankle sprain until now, consider yourself lucky! While they can initially be very painful and limiting, most people respond very well to a structured ankle sprain rehab program. However, there is clearly a serious issue with the average ankle sprain rehab protocol because not only are ankle sprains the most common lower-body injury, but they also have the highest reinjury rate. This is often attributed to poor management in the first place, and chronic ankle instability is the last thing you want to deal with! In this article, you will learn everything you need to know about a lateral ankle sprain injury and the best ankle sprain rehab protocol!

After watching, you may want to consider our ankle sprain program that’ll guide you to where you want to be!
Learn What You Need To Perform Ankle Sprain Rehab At Home
Lateral ankle sprains can be challenging and frustrating due to having the highest injury AND reinjury rate amongst any lower-body injury. The high reinjury rates are likely because most ankle sprains aren’t properly managed in the first place. It’s time to change the narrative with [P]Rehab – we’ve designed a solution for you to get back to normal life while protecting your ankles into the future! Learn more HERE!
What exactly is an Ankle Sprain?
An ankle sprain is an injury to the ligaments of the ankle. Ligaments are a type of connective tissue that connects bones to other bones to provide stability to joints and prevent excessive movement. While the ankle has an abundant supply of ligaments, the most commonly sprained ligaments in the ankle are all on the lateral or outside portion of the ankle. A lateral ankle sprain refers to a ligament injury of either the anterior talofibular (ATFL) and/or posterior talofibular ligament (PTFL) and/or the calcaneofibular ligament (CFL). These ligaments are described based on what bones they connect to. These ligaments collectively provide stability to the lateral aspect of the ankle. It is much easier to sprain the lateral ankle ligaments versus the medial ankle ligaments or the structures involved in high ankle sprains because of the common mechanism of injury (rolling the ankle) and the lateral ligaments are simply inferior in comparison when it comes to their quantity and design. Up to 70% of the general population have or will experience a lateral ankle sprain in their lifetime, that’s crazy! What is even scarier is how high the reinjury rate is for lateral ankle sprains, especially within the first year (two-fold reinjury risk) making it the highest reinjury rate amongst all lower-body injuries (1).
Lateral Ankle Ligamentous Anatomy
In general, ankle ligament injuries are classified into three grades representing increasing severity.
- Grade I = mild ankle sprain, 2-4 week recovery
- Grade II = moderate ankle sprain, 1-2 month recovery
- Grade III = severe ankle sprain; full ligament tear, 3+ month recovery
These grades are typically only assessed through imaging, although a full tear can be assessed by a trained physical therapist or orthopedist. Understand, however, that most ankle sprains do not require imaging. Imaging (like x-rays) should only be used if a fracture is suspected, in this case you want to push pause on your ankle sprain rehab.

Ankle Sprain Rehab: First Rule Out a Fracture
Even if the ankle sprain looks really bad with tons of bruising, you should only seek out imaging based on the Ottawa Ankle Rules below:
- Can you take 4 steps (it’s okay if you need to limp)? NO? –> GET AN XRAY
- Do you have tenderness/pain around your medial or lateral malleoli (the little bone bumps on either side of your ankle)? Specifically the backside of the bones? YES? –> GET AN XRAY
- Do you have tenderness/pain around the base of the 5th metatarsal (bump on the lateral/outside portion of your foot; halfway between your heel and your little toe)? YES? –> GET AN XRAY
- Do you have tenderness/pain around the navicular bone (bump on the medial/inside portion of your foot?) YES> –> GET AN XRAY

Ankle Sprain Rehab And Treatment: Early Mobility Is Key!
The old adage of Rest, Ice, Compression, and Elevation (RICE) for ankle sprain rehab is far outdated. Complete rest is one of the worst things you can do following an ankle sprain, and instead, a new acronym called P.O.L.I.C.E is now the recommendation. Rest is replaced by Protection, and Optimal Loading. This means that early on, we need to protect the injured areas by not over-stressing the tissues, but still apply healthy sub-maximal loads to the tissues that actually stimulate the healing process. More on these exact exercises in a bit, but make sure you watched the video at the beginning of this article to learn how to safely progress exercises!
Furthermore, recent research has shown that the individual elements of RICE alone are not effective, apart from icing immediately after the injury for the first few days, if given along with exercise. This means that the most important part of ankle sprain rehab is providing protection and optimal loading through exercise, not the rest/icing/compression/elevation that is typically recommended!
Early Ankle Sprain Rehab Exercises
Protection of the injured area immediately after an ankle sprain means that we should strive to not do any activities or movements that cause an increase in baseline pain levels. This means that the general rule of thumb for these exercises is only to move within your tolerable pain-free ranges! Because most ankle sprains involve the ligaments on the outside of the ankle, moving the ankle inwards will typically cause discomfort. This is because you are putting a little stretch on the injured ligament, so be cautious with the inward direction in the first week or so!

Once you get comfortable exploring your pain-free ranges of motion, you can easily use a theraband to begin to apply some resistance to your exercises. The goal again is to push as much as you can, without increasing your baseline levels of pain too much.

Once you are able to bear weight and walk comfortably without an increase in baseline levels of pain afterward, your ankle sprain rehab should consist of all standing exercises; ideally on one leg or unstable surfaces to challenge your ankle stability and proprioception. The ankle ligaments provide feedback to your body which assists in things like balance, that’s why focusing on neuromuscular control exercises is a must! The options are endless for ankle sprain rehab when you reach this stage in your recovery, but some of our favorite exercises are below.
Don’t Skip Out On Balance Exercises For Ankle Sprain Rehab
Balance exercises are an absolute must for ankle sprain [P]Rehab! This is because the ankle joint and ankle ligaments are highly responsible for joint proprioception, which is the body’s understanding of where it is in space. Without training these joint proprioceptors with various balance exercises that simulate daily activity, one may be predisposed to recurrent ankle sprains in the future. Remember, ankle sprains have the highest recurrence rates of any lower-body injury, so the best thing you can do to prevent them in the first place is bulletproof your ankle joints with balance and strengthening exercises! We will provide some examples of balance exercises below.
Single Leg Balance
Use Unstable Surfaces
Should I Take Pain Medication?
Ultimately this is a question of preference and your pain tolerance. NSAIDs like Motrin, Advil, and Celebrex are considered over the counter and readily available to most individuals. While they can decrease pain and swelling after an ankle sprain, there is newer ongoing research on the potential negative effects on NSAIDs as they delay and suppress the body’s natural healing process. Our body initially heals through inflammation, so do we want to limit it? In our opinion (not medical advice), take NSAIDS early on if you absolutely need to and can’t handle the pain, but discontinue them as soon as your pain and swelling are under control (1).
Should I Use An Ankle Brace?
Yes! Early on, a lace-up or semi-rigid ankle brace will allow you to load the injured ligament in a protected manner. These types of braces allow some motion but limit excessive motion that would typically delay the healing process early on. Understand that when in a brace, you are limiting the loads to the healing ligament (which the ligament needs to heal). This is advantageous early on but is not advised in the long term during day to day activities. Ankle braces can in fact be used for athletes when they are back to playing sports for prevention, so don’t completely discredit the use of an ankle brace!
