Strains and sprains are a more common type of injury followed by fractures in lower extremities. Statistics show that the most injured part in the young population between the age of 12 to 19 is their feet or ankles being 33%, which is double the proportion reported by seniors at 14%.

The leading causes of injuries were falls and overexertion, with falls being the most common cause of injuries. With 50% of injuries are among adolescents following a fall, while among adults, this amount is even higher 63%. Sports-related injuries were mainly caused by falls and accounted for three in five falls.

Lateral ankle sprain commonly addressed as an ankle sprain is one of the common conditions seen in outpatient physiotherapy clinics. Clients presenting with acute ankle sprains have swelling, pain on weight-bearing, lack of movement in the ankle.

Causes of Lateral Ankle Sprain:

A lateral ankle sprain usually occurs with incorrect placement of foot with the ankle and foot in an inverted position during the initial point of contact, placing the ankle in a more vulnerable position.

An ankle sprain is a common injury sustained by individuals participating in recreational sports and physical activities.

Risk Factors for Lateral Ankle Sprain:

A previous history of Ankle Sprain – In a study based on risk factors for ankle sprain among active university students de Noronha el. reported that the participants with a history of previous ankle sprain were twice as likely to have a subsequent sprain. Ankle sprains have the highest re-injury rates of all lower limb soft tissue injuries, with a double fold increased risk of re-injury within one year.

Ankle Injury During Sports
Ankle Injury During Sports
  • Decreased strength of the ankle and leg muscles may increase the risk of sustaining an ankle sprain
  • Impairments in postural balance
  • Not enough warming up and stretching before sports, activities, and exercises
  • Participation in certain sports is associated with an increased risk of sustaining a lateral ankle sprain, most common being from men’s basketball, women’s basketball, women’s soccer, and women’s lacrosse. (Roos et al.) 

Chronic Ankle Instability:

Although many go on to having a full recovery after an acute ankle sprain, however, there is a reality that up to 70% are known to have repetitive ankle sprain/injury (McKay et al. 2001) leading to chronic ankle instability and having long term symptoms of dysfunction or disability.

Chronic ankle instability is when there are residual symptoms that go on for a longer duration or most of the time after having one or more acute ankle sprains. Chronic ankle instability may negatively impact an individual’s ability to participate in physical activity and, therefore, can increase the risk of long-term problems such as early-onset post-traumatic osteoarthritis. (Golditz T et al. 2014)

Signs of Chronic Ankle instability:

  • Feeling of the ankle “giving way,” a sensation of having instability
  • Having recurrent ankle sprains
  • Functional deficits in balance, gait, sports-related activities

A test used to assess ankle instability clinically or Anterior Drawer test of the ankle and Single leg stance.

Single Leg Stance test required the patient to stand on the test limb without shoes as appropriate, with the opposite knee bent and without touching the test limb. With eyes open, the individual fixes their gaze on the spot in front and then stay with eyes closed for 10 seconds.

A positive test is when the individual reported a sense of instability, if the opposite leg touches the test leg, increased movement of the test foot on the floor, or non-test limb touching down.

What causes chronic ankle problems?

Ankle Ligament
Ankle Ligament

After a lateral ankle sprain, ligament injury occurs, but also neuromuscular structures surrounding the ankle joint are also affected. Following an ankle injury deficit in an individual’s ability to stabilize the ankle joint in dynamic conditions due to impairment in movement sense and awareness of the position of the ankle joint in space is due to damage to muscle mechanoreceptors.  

The prognosis for Lateral Ankle Sprains

A recent study noted that the clinical outcomes or prognosis after lateral ankle sprain was not determined just by the severity of the injury. Some individuals with simple injuries go on to have chronic problems, whereas some with complex injuries recovered fully in a short period. Evidence suggests that the severity of an ankle injury determined by imaging does not necessarily dictate the severity of symptoms and the prognosis for their recovery. (Bullock SA et al. 2018).

Ankle Pain Physiotherapy

The evidence-based treatment and rehabilitation programmes are associated with better prognosis and faster time to return to sport and activities.

Initial Management of Ankle Sprains:

When an injury appears severe with noted abnormalities on radiographs, the individuals are referred to the fracture clinic for further assessment and management.

Most patients who visit emergency or physician’s office that have NO signs or evidence of a fracture, a conservative management approach is taken with the most common advice given to be

  • PRICE (Protection, Rest, Ice, Compression, Elevation) NSAID’s to self-manage recovery at home.
  • Compression bandage being the most common adjunct given to patients.

Ankle ligamentous sprain injury management, as mentioned, is mainly conservative. This approach may be sufficient for many, yet some individuals who go on to develop more persistent ankle issues or have a delayed recovery require further consultations and need referrals to Allied Health Professionals (Bullock SA et al. 2018).

Ankle Brace

Evidence-based clinical guidelines informed that though a short time of immobilization may help relieve pain and swelling. However, Immobilizing the joint in the absence of fracture or instability can result in joint stiffness, muscle atrophy and loss of proprioception. 

 However, after acute lateral ankle ligament injury benefits most from the use of taping, a brace in combination with an effective exercise programme. A Study reported caution with taking non-steroidal anti-inflammatory drugs (NSAIDs) after an ankle sprain. NSAID’s reduce pain and swelling, but usage is not without complications as this may suppress the natural healing process. (Vuurberg G, Hoorntje A, Wink LM, et al. 2018)

Treatment based on supervised exercise programmes is preferred over passive modalities as it stimulates the recovery of functional joint stability.

Post Ankle injury Rehabilitation through Physiotherapy

There is grade A evidence showing that conservative ankle rehabilitation program produces substantial improvements in Health-Related Quality of Life for people with chronic ankle instability (Powden CJ et al. 2017)

An Active Solution to Ankle Injury Management

active fitness

Several studies are supporting Proprioceptive training programs and balance training to be quite effective in reducing the recurrence of ankle sprains. Individuals who participate in physical activities and sports should pursue specific, targeted, and ongoing exercise-based programs. Evidence suggests that higher exercise loads after injury (> 900 minutes) are associated with the lower risk of re-injury (Bleakley C.2017)

A physiotherapist can help you manage and treat your persistent ankle problems, through active rehabilitation strategies to improve ankle function for individuals with Chronic Ankle Instability. Training can include Proprioceptive, Balance training, manual therapy, specific strength, and neuromuscular training exercises to achieve your functional ability and return to sports and activities of daily living.
