Management of Acute Ankle Sprains

Introduction to Evidence-Based Treatment

The British Journal of Sports Medicine recommends against the use of ice as a standalone treatment for acute ankle sprains, citing a lack of evidence for its effectiveness in reducing pain, swelling, or improving function 1, 2
The American Heart Association suggests that ice may be used for comfort, but only as an adjunct to other treatments, and not as a primary therapeutic measure 6

Isolated ice application does not increase function, decrease swelling, or reduce pain at rest in patients with acute lateral ankle sprains, based on 27 randomized controlled trials involving 1,670 patients 1, 2
The RICE protocol lacks evidence to support its use as a conservative treatment method, with little scientific support for reducing injury-associated symptoms 1, 3
Compression therapy after acute ankle sprains is inconclusive, based on only 3 RCTs with 86 patients 1

Cryotherapy combined with exercise has a greater effect on reducing swelling compared to heat application (1 RCT, n=30) 1
The combination of cryotherapy and exercise results in significant improvements in ankle function in the short term, allowing increased weight-bearing compared to standard functional treatment (1 RCT, n=101) 1

The treatment with the strongest evidence (Level 1) is supervised exercise therapy combined with functional bracing, not ice 1, 4, 3
The American College of Sports Medicine recommends supervised exercise therapy and functional bracing as the primary treatment for acute ankle sprains 1

Immediate phase (first 24-72 hours): apply functional support with semirigid ankle brace, avoid activities that cause pain, consider NSAIDs for pain control, and limit ice use to 20-30 minutes without direct skin contact 4, 5, 6, 1, 7
Early mobilization phase (48-72 hours post-injury): begin supervised exercise therapy focusing on proprioception, strength, coordination, and function, and continue semirigid ankle brace for 4-6 weeks 1, 4, 5
Progressive rehabilitation: range of motion exercises, strengthening exercises addressing muscle deficits, proprioception training, and sport-specific drills when appropriate 4, 5, 7

Patients return to sports 4.6 days sooner with functional treatment versus immobilization 7, 4, 3
Patients return to work 7.1 days sooner with functional treatment versus immobilization 7, 4, 3
Lace-up or semirigid supports are more effective than tape or elastic bandages 7, 4

Relying on RICE alone without active rehabilitation delays recovery and provides no proven benefit 1, 3
Prolonged immobilization shows no benefits compared to functional treatment and leads to worse outcomes 1, 7, 3
Excessive rest without early mobilization is inferior to functional treatment for all measured outcomes 7
Delaying exercise therapy is detrimental, as exercise should begin within 48-72 hours 1, 4, 5

Optimal clinical assessment of ligament damage should be delayed 4-5 days post-injury when swelling has decreased, achieving 84% sensitivity and 96% specificity 1, 4, 5
