Why Physiotherapy is Critical for Lateral Ankle Sprain Recovery
Physiotherapy is a critical component of lateral ankle sprain recovery because it focuses on restoring stability, strength, and proprioception to prevent chronic ankle instability (CAI). Furthermore, physiotherapy helps in reducing swelling and scar tissue, and correcting compensatory movement patterns.
Here's why physiotherapy is so important for recovery:
- Restoring stability, strength, and proprioception: Rehabilitation regimens that include therapeutic exercises are crucial for a successful return to activity and reducing the risk of re-injury. In the subacute and chronic stages of rehabilitation, emphasis should be placed on increasing the proprioceptive sense and muscle strength, as well as improving the biomechanics of daily life and sports-specific movements. Proprioceptive training, in addition to strengthening exercises, aids with rehabilitation. Alterations in muscle activity and changes in the kinematics of the lower extremity may predispose individuals to continued instability at the joint and long term health issues, so minimizing dysfunction through physiotherapy may improve short and long-term function.
- Reducing swelling and scar tissue: The initial management of lateral ankle sprains includes strategies aimed at reducing swelling and pain. After the first 72 hours, physiotherapy forms the mainstay of treatment. Manual therapy techniques such as soft tissue massage can help alleviate pain and improve mobility. Applying a compression bandage can also help control swelling and provide support to the injured area.
- Correcting compensatory movement patterns: Alterations in muscle activity and kinematics may predispose individuals to continued instability at the joint and long term health issues. A comprehensive approach to rehabilitation includes not only range of motion and strengthening exercises, but also proprioceptive training, and sports-specific exercises. Functional training that mimics sports-specific movements can help prepare the athlete for a return to activity. Also, from a biopsychosocial perspective, the patient should be approached holistically in both the evaluation, and in the treatment phases.
Prognosis: How Long Does a Lateral Ankle Sprain Take to Heal?
The time it takes for a lateral ankle sprain to heal depends on the severity of the sprain, which is graded from 1 to 3.
The general timelines for recovery are:
- Grade 1 sprain: 1–3 weeks.
- Grade 2 sprain: 4–6 weeks.
- Grade 3 sprain: 8–12 weeks and may require bracing or surgery.
Other factors can affect how long it takes to heal from a lateral ankle sprain. These include:
- Adherence to the rehabilitation program
- The severity of the sprain
- Activity demands
It is worth noting that 80% of acute ankle sprains make a full recovery with conservative management, while 20% develop mechanical or functional instability, potentially leading to chronic ankle instability. Up to 75% of initial lateral ankle sprains can lead to repetitive sprains and chronic symptoms. Inadequate rehabilitation can lead to residual symptoms in 55% to 72% of patients at 6 weeks to 18 months.
Physiotherapy Treatment for Lateral Ankle Sprains
Physiotherapy treatment for lateral ankle sprains progresses through several phases, each with specific goals and exercises.
Acute Phase Management (0–72 Hours)
- Rest, Ice, Compression, Elevation (RICE): Initial management of an acute lateral ligament injury focuses on reducing pain and swelling through the RICE protocol. Functional treatment includes the RICE protocol. RICE includes rest, ice, compression, and elevation. Keeping the ankle elevated above heart level can help reduce swelling and promote venous return.
- Gentle ankle pumps and non-weight-bearing mobility: Active and passive mobilization of the foot and ankle is done to reduce pain and prevent venous stasis, and improve local circulation allowing resorption of oedema. If weight bearing is too painful, crutches can be used for non-weight bearing for 24 hours, but partial weight bearing should be initiated relatively soon, together with a normal heel-toe gait pattern, as this will help to reduce pain and swelling.
Subacute Phase (1–3 Weeks)
- Isometric exercises: Isometric exercises like resisted ankle eversion can be introduced. Eversion is especially important.
- Partial weight-bearing with crutches or a brace: Partial weight bearing should be initiated relatively soon, together with a normal heel-toe gait pattern, as this will help to reduce pain and swelling. A brace or tape can also be applied, at the beginning of this phase, to protect the joint.
Strengthening and Proprioceptive Training (3–6 Weeks)
- Eccentric heel drops and resistance band exercises: Strengthening exercises are a key part of rehabilitation.
- Single-leg balance drills and wobble board training: Proprioception training should begin as soon as pain allows during the rehabilitation programme. In addition to strengthening exercises, proprioceptive re-training helps with rehabilitation.
Functional and Sport-Specific Training (6+ Weeks)
- Lateral shuffles, cutting drills, and plyometric jumps: As recovery progresses, functional training that mimics sports-specific movements can help prepare the athlete for a return to activity. Functional movements such as lunges and hopping should be included in the assessment.
- Before returning to full functional activity the patient should have full range of pain free movement in the ankle, normal strength and normal proprioception. If returning to sports, the athlete should be encouraged to wear an ankle brace or to tape the ankle for a further 6 months to provide external support.
Manual Therapy
- Soft tissue mobilization to improve range of motion and reduce adhesions: Gentle soft tissue massage can be performed to assist with the removal of oedema, and gentle stretches can be done as long as they are pain free. Techniques such as joint mobilization and soft tissue massage can help alleviate pain and improve mobility.
Goals of care during the acute inflammatory phase are to reduce inflammation and pain and to protect the ligament from further injury.
During the reparative and remodeling phase, the goal is to progress the rehabilitation appropriately to facilitate healing and restore the mechanical strength and proprioception. In the subacute and chronic stages, emphasis should be placed on increasing the proprioceptive sense and muscle strength, improving the biomechanics of daily life and sports-specific movements such as walking, running, and jumping.
Preventing Recurrent Lateral Ankle Sprains
To prevent recurrent lateral ankle sprains, focus on strength training, proprioceptive exercises, and proper footwear and bracing.
Here's how to address each of these areas:
- Strength Training: Strengthening the muscles around the ankle is crucial for stability and support. Key muscle groups to target include:
- Peroneals: Strengthening exercises, with eversion being especially important.
- Calves: Strengthening the calf group, made up of the gastrocnemius and soleus, is key.
- Hip stabilizers: Strengthen hip muscles, especially hip extensor strength.
- Proprioceptive Work: Proprioception, or joint position sense, is essential for preventing ankle sprains. Daily balance exercises can improve proprioception and include:
- Single-leg stands: Simple single leg stance can be progressed by asking the patient to reach outside their base of support, rotating their neck or by closing their eyes. Moving onto a wobble board or any other unstable surface will allow the therapist to assess the patients ability to respond to a changing surface.
- Footwear and Bracing:
- High-top shoes for sports: Wearing ankle braces and performing balance training has been shown to reduce the risk of recurrent ankle sprains.
- Ankle braces: If returning to sports, the athlete should be encouraged to wear an ankle brace or to tape the ankle for a further 6 months to provide external support. There is still some contradiction in the literature about the effects of taping and braces in both the acute and chronic phases of ligament sprains of the ankle.
FAQs About Lateral Ankle Sprains
Here are some answers to frequently asked questions about lateral ankle sprains:
"How do I know if my sprain is serious?"
- A comprehensive history and examination aid in diagnosing the severity and type of ankle sprain. Ligament sprains are classified into grades:
- Grade 1: Mild, with pain and minimal tearing of ligament fibers. Symptoms include minimal swelling and point tenderness directly over the ATFL, little to no instability, and the ability to ambulate with little to no pain.
- Grade 2: Moderate, with pain and significant tearing of ligament fibers. Symptoms include a broader region of point tenderness over the lateral aspect of the ankle, a painful gait or inability to ambulate, bruising and localized swelling due to tearing of the anterior joint capsule, ATFL, and surrounding soft tissue structures.
- Grade 3: Severe, sometimes not painful, with complete rupture of the fibers. Symptoms include diffuse swelling that obliterates the margins of the Achilles tendon, inability to ambulate, and tenderness on the lateral and medial aspects of the ankle joint. Grade III ankle injury may be treated with surgery if the symptoms persist post functional treatment.
- Radiographic imaging techniques may need to be used to rule out fractures, complete ligament tears, or instability of the ankle mortise. If a patient is unable to weight-bear immediately following the injury, an X-ray is indicated because of the risk of a clinically significant ankle fracture. Failure to use the Ottawa rules to assess for ankle fracture may be significant in any legal proceedings should they occur.
"When can I start running after a lateral ankle sprain?"
- Before returning to full functional activity the patient should have full range of pain free movement in the ankle, normal strength and normal proprioception. According to a recent systematic review there are currently no published evidence-based criteria to inform return-to-work decisions for patients with a lateral ankle sprain injury. If the patient is an athlete, return to sports should be planned after the criteria are met.
"What’s the difference between a sprain and a fracture?"
- A sprain is defined as the stretching or tearing of ligaments. Ligaments in the ankle include the lateral ligamentous complex, deltoid ligament, and distal tibiofibular syndesmosis ligaments. A fracture is a break in a bone. If a patient is unable to weight-bear immediately following the injury, an X-ray is indicated because of the risk of a clinically significant ankle fracture. Ottawa Ankle Rules provide useful guidance on determining the presence of a fracture.
