Physiotherapy for ankle sprains

Ankle sprains are a common injury in everyday life and sports, and can be associated with pain, oedema and functional limitations. In some cases, it can significantly interfere with walking, balance and participation in normal activities. Physiotherapy plays a central role in dealing with these situations, supporting the recovery process and functional readaptation.

What is an ankle sprain?

An ankle sprain occurs when the ligaments that stabilise the joint are subjected to excessive stretching or partial or total rupture. This mechanism usually occurs after a sudden movement, such as a twist, an imbalance or a fall.

The clinical presentation can vary depending on the severity of the injury and can include local pain, swelling, a feeling of instability, limited mobility and difficulty bearing a load on the affected limb.

Classification of ankle sprain

From a clinical point of view, ankle sprains can be categorised according to the severity of the ligament injury:

• Grade I: ligament stretch, usually associated with mild pain and slight oedema
• Grade II: partial rupture, may be associated with moderate pain, swelling and some instability
• Grade III: complete rupture, usually accompanied by significant oedema and marked instability

This classification can help guide clinical reasoning and tailor physiotherapy intervention, taking into account the healing times and functional capacity of each person.

The role of physiotherapy in ankle sprain recovery

Physiotherapy is part of the recovery process from the initial stages to the progressive return to activity. Intervention is guided by an individualised clinical assessment, which takes into account the degree of injury, the symptoms presented, the person's level of activity and functional goals.

The physiotherapist works to manage symptoms, restore joint and muscle function and reduce the risk of recurrence, while respecting the biological healing times of the tissues.

Benefits of physiotherapy in ankle sprain recovery

• Pain and inflammation management: In the early stages, intervention can focus on controlling pain and swelling. Strategies based on current evidence can be used, such as the PEACE & LOVE protocol framework, combined with manual therapy techniques and exercises adjusted to the stage of the injury.
• Support for the healing process: Through joint mobilisation, manual techniques and progressive stimulation of movement, physiotherapy can help to reorganise the tissues and recover the function of the ankle joint.
• Recovery of mobility and stability: After a sprain, there may be limitations in movement and changes in stability. Physiotherapy can integrate mobility exercises, strengthening and proprioceptive training, with the aim of improving neuromuscular control and the joint's ability to respond.
• Reduced risk of recurrence: Previous sprains can be a risk factor for new episodes. Strength, balance and motor control work can help improve the functional stability of the ankle and reduce the likelihood of recurrence or persistent instability.

Importance of individualised assessment

Not all sprains evolve in the same way. In addition to the severity of the injury, factors such as the history of previous sprains, the type of physical activity, movement patterns and the quality of motor control can influence the recovery process.

Physiotherapy assessment makes it possible to analyse not only the ankle, but also how the foot, knee and hip participate in the movement, as well as the balance strategy and response to load. This global reading can be important in guiding intervention.

When to consider a physiotherapy assessment

Functional assessment in Physiotherapy can be particularly pertinent when:

• Pain and oedema persist beyond the first few days
• There is a feeling of instability or insecurity when walking
• Difficulty resuming normal or sporting activities
• Repeated episodes of sprain occur
• Compensations arise in the knee, hip or spine

Early intervention can help prevent less efficient adaptations and reduce the risk of chronic ankle instability.

Return to activity and load progression

The return to day-to-day activities or sport should be gradual and targeted. The absence of pain at rest alone may not be enough to ensure that the joint is prepared to respond to demands such as rapid changes in direction, jumping or uneven terrain.

In Physiotherapy, load progression is helped based on function, movement control and individual tolerance, supporting a safer and more sustained return.

Ankle sprain and functional rehabilitation

Recovery from an ankle sprain is not limited to resolving the pain. The physiotherapy approach seeks to restore the overall function of the lower limb, taking into account gait, balance, coordination and adaptation to the demands of everyday life or sport.

Physiotherapy therefore plays an important role in monitoring these injuries, supporting a progressive, safe recovery tailored to individual needs.

In the event of an ankle sprain, a functional assessment in Physiotherapy can help frame the injury, guide the appropriate intervention and define strategies that favour functional recovery and the prevention of future limitations.
