Brief Summary

Acute, severe lateral ankle sprains are estimated to comprise between 3-5% of emergency department visits and are the most common musculoskeletal injury in the physically active population. Although the current accepted treatment of ankle sprains is to encourage early mobilization with functional rehabilitation, there is little high-quality evidence directing this clinical practice. This pilot study is to:

  • provide quantitative data for estimation of mean outcome scores and standard deviations to allow subsequent sample size calculations
  • evaluate the feasibility of the proposed study design
  • assess patient enrollment issues specific to randomization into an active rehabilitation program compared to below knee immobilization.

Outcome Measures

Primary Outcomes (1)

  • Change from baseline Foot and Ankle Outcome Score (FAOS)measured at 1 and 3 months.

    Measured at 0, 1, and 3 months

Study Arms (2)

Immobilization

ACTIVE COMPARATOR

50 patients will be randomly assigned to have their lateral ankle sprain immobilized in a below knee cast

Procedure: Below knee plaster casting

Functional Rehabilitation

ACTIVE COMPARATOR

50 patients will be randomly assigned to a functional rehabilitation program for their lateral ankle sprain

Procedure: Functional rehabilitation

Interventions

Subjects will be randomly assigned to either immobilization of their lateral ankle sprain with a below knee cast or to enter a functional rehabilitation program

Immobilization

Subjects will be randomly assigned to either immobilization of their lateral ankle sprain with a below knee cast or to enter a functional rehabilitation program
