Interventions
Neuromuscular training and proprioceptive exercises
10 RCTsBalance and proprioceptive training (e.g. single-leg standing on unstable surfaces, wobble boards) is the most evidence-supported intervention for preventing recurrent ankle sprains. Programmes typically last 6-8 weeks and should be continued as maintenance. Evidence shows a 35-50% reduction in recurrence rates with regular proprioceptive training.
Evidence does not support: Proprioceptive training should not be started before weight-bearing is tolerable. Ankle bracing alone without neuromuscular training provides inferior long-term outcomes.
- Acute phase with inability to weight-bear
- Suspected fracture (apply Ottawa ankle rules first)
Early mobilisation and functional rehabilitation
7 RCTsEarly weight-bearing and mobilisation (within pain tolerance) leads to faster recovery than immobilisation for grade I-II ankle sprains. The RICE protocol (rest, ice, compression, elevation) in the first 48-72 hours followed by progressive functional rehabilitation is the standard approach. Most grade I sprains recover within 1-3 weeks; grade II within 3-6 weeks.
Evidence does not support: Prolonged immobilisation in a cast or boot for uncomplicated grade I-II sprains is not supported and leads to worse functional outcomes. Complete rest beyond the acute phase delays recovery.
- Suspected fracture (positive Ottawa ankle rules)
- Grade III sprain with gross instability
Ankle bracing or taping for return to sport
6 RCTsExternal ankle supports (semi-rigid braces or athletic taping) during return to running reduce the risk of re-injury, particularly in the first 6-12 months after injury. Lace-up braces are generally preferred over rigid braces for runners as they allow more functional movement while still providing support.
Evidence does not support: Long-term dependence on ankle bracing without addressing underlying strength and proprioceptive deficits is not recommended. Bracing should complement, not replace, rehabilitation.
- Skin conditions or wounds at the brace site
- Allergy to brace materials
Manual therapy and joint mobilisation
4 RCTsManual therapy techniques including ankle joint mobilisations (particularly talocrural posterior glides) can improve dorsiflexion range of motion after ankle sprain. This is often used as an adjunct to exercise-based rehabilitation in the subacute phase.
Evidence does not support: Manual therapy as a standalone treatment without active exercise rehabilitation is not supported for long-term outcomes.
- Acute fracture
- Severe ligament disruption with gross instability
Red Flags
Inability to weight-bear for four steps immediately after injury
Action: Apply Ottawa ankle rules — radiograph required to rule out fracture. Seek medical assessment.
Bony tenderness at the posterior edge or tip of the medial or lateral malleolus
Action: Seek radiographic assessment to rule out fracture (Ottawa ankle rules positive).
Severe swelling and bruising with joint instability or giving way
Action: Seek medical assessment — may indicate grade III sprain or syndesmosis injury requiring specialist management.
Differential Diagnoses
- Ankle fracture (malleolar or talar)
- High ankle sprain (syndesmosis injury)
- Peroneal tendon subluxation or tear
- Osteochondral lesion of the talus
Frequently asked questions
What is the best evidence-based treatment for Lateral Ankle Sprain?
The highest-rated treatment for Lateral Ankle Sprain based on peer-reviewed research is Neuromuscular training and proprioceptive exercises (Trust Score: 85/100).
