An ankle sprain is a common musculoskeletal injury, affecting athletes and non-athletes
alike. Whether you rolled your ankle running, jumping or even stepping off a curb,
understanding your injury is the first step toward a successful recovery and return to pain
free activity.
What Is an Inversion Ankle Sprain?
An inversion ankle sprain is the most common type of ankle sprain. It occurs when the foot
rolls in, causing stretching or tearing of the ligaments on the outside of the ankle.
The two ligaments most commonly sprained are:
- Anterior Talofibular Ligament (ATFL) – The most common ankle ligament to be
injured. - Calcaneofibular Ligament (CFL) – Often injured with more moderate to severe
sprains.
How Is an Inversion Sprain Different from Other Ankle Sprains?
Ankle sprains are not all the same.
- Inversion sprain: The foot rolls inward, injuring the ligaments on the outside of the
ankle. - Eversion sprain: The foot rolls outward, injuring the stronger ligaments (deltoid
ligaments) on the inside of the ankle. These injuries are much more rare. - High ankle sprain (syndesmotic sprain): This injury affects the connective tissue,
called syndesmosis, connecting the tibia and fibula above the ankle joint. High
ankle sprains often occur with twisting injuries, usually requiring significantly longer
to heal, and commonly require a longer rehabilitation period before returning to
sports.
Grades of Ankle Sprains
The severity of an ankle sprain is classified into three grades: Grade I, II, III
Grade I (Mild)
Grade I sprain involves overstretching of the ligament without tearing.
Common symptoms include:
- Mild pain
- Minimal swelling and bruising
- Little to no loss of ankle stability
- Near full or full ability to bear weight
Because the injury is less severe, patients with a Grade I sprain often return to normal
activities and recreational activities fairly quickly with appropriate rehabilitation.
Grade II (Moderate)
Grade II sprain involves a partial tear of the ligament.
Common symptoms include:
- Moderate pain
- Increased swelling and bruising
- Pain with walking and weight bearing
- Reduced range of motion
- Mild to moderate joint instability
Depending on the severity of symptoms, some individuals may benefit from temporary
immobilization using a walking boot or brace before progressing into rehabilitation.
Grade III (Severe)
Grade III sprain is a complete rupture of the ligament.
Common symptoms include:
- Severe pain (although pain may lessen after the initial injury due to complete
tearing) - Significant swelling and bruising
- Severe difficulty or inability to bear weight
- Noticeable ankle instability
- Difficulty walking without assistance
Grade III sprains often require a period of immobilization to allow appropriate healing
before beginning progressive rehabilitation. A comprehensive physical therapy program is
essential to restore strength, balance, and stability while reducing the risk of future sprains.
RICE vs. MEAT: Which Approach Is Best?
We have all heard of the RICE method. It has been the standard recommendation following
an ankle sprain and many other musculoskeletal injuries. As we learn more, there is
another approach that is also beneficial called the MEAT method, emphasizing progressive
movement and rehabilitation.
The RICE Method
RICE is most beneficial during the first 24 to 72 hours following an injury to help manage
pain and swelling.
- Rest: Avoiding activities that could cause further injury or increase pain.
- Ice: Utilize ice or a cold pack for 10–20 minutes at a time, during the first 24 hours to
help reduce pain and swelling. - Compression: Use a wrap to help minimize swelling and provide gentle support.
- Elevation: Elevate the ankle, above heart level, to decrease swelling.
RICE is appropriate for minor acute injuries but should not replace medical evaluation if
you suspect a fracture or severe ligament injury.
The MEAT Method
Once the acute symptoms begin to settle, the focus shifts toward active recovery. The
MEAT approach promotes tissue healing through movement and progressive loading.
- Movement: Start with small, comfortable ankle movements as soon as symptoms
allow to help preserve motion and limit stiffness. - Exercise: Build strength gradually in the muscles that support the ankle while also
working on balance, body awareness, and control. - Analgesia: When appropriate, use recommended pain-management options so
rehabilitation activities can be performed more comfortably. - Therapy: Physical therapy may combine hands-on care, mobility exercises,
strengthening, balance work, and activity- or sport-specific training to support a
safe recovery.
Rather than choosing one method over the other, check with your physical therapist to see
which method is best for you based on your healing timeframe and specific needs.
Why Physical Therapy Matters
Many people assume an ankle sprain will simply heal on its own. While pain may improve,
untreated ankle sprains can lead to lingering weakness, poor balance, repeated sprains,
chronic instability, and ongoing discomfort.
At Inspired Physiotherapy, our treatment plans are individualized and may include:
- Hands-on manual therapy
- Swelling management
- Range of motion exercises
- Progressive strengthening
- Balance and proprioception training
- Sport- and activity-specific rehabilitation
- Return-to-sport testing and guidance
Our goal is not only to help you recover but to reduce your risk of future ankle injuries.
When Should You See a Physical Therapist?
Consider scheduling an evaluation if you:
- Cannot comfortably bear weight after your injury.
- Have significant swelling or bruising.
- Feel like your ankle is unstable or “giving way.”
- Continue to have pain after several days.
- Have experienced multiple ankle sprains.
- Want to safely return to work, exercise, or sports.
Don’t Let an Ankle Sprain Slow You Down
Whether you’ve sustained a mild Grade I sprain or a more significant Grade III injury, early
evaluation and appropriate rehabilitation can make a significant difference in your recovery. At Inspired Physiotherapy, we’re here to help you regain confidence, restore
strength, and get back to doing what you love safely and efficiently.
If you’ve recently rolled your ankle or are dealing with lingering instability from a previous
sprain, contact Inspired Physiotherapy to schedule an assessment. Together, we’ll create a
personalized treatment plan to help you move confidently again.
