Individuals with self-reported chronic ankle instability do not show impaired functional performance in common tests. Despite subjective symptoms, objective measures indicate no significant performance deficits in these athletes.

Area of Science:

  • Sports Medicine
  • Biomechanics
  • Orthopedics

Background:

  • Chronic ankle instability (CAI) is frequently reported by athletes after ankle sprains.
  • Subjective symptoms of CAI include feelings of instability and recurrent "giving way" episodes.
  • The impact of subjective CAI on objective functional performance remains debated.

Purpose of the Study:

  • To investigate whether self-reported chronic ankle instability affects functional performance.
  • To compare the functional performance of individuals with and without a history of ankle injury.
  • To analyze performance in cocontraction, shuttle run, and agility hop tests.

Main Methods:

  • A between-groups design compared 20 men with CAI to 20 matched controls without ankle injury history.

  • Functional performance was assessed using cocontraction, shuttle run, and agility hop tests.
  • Performance metrics included time to completion and an error point scale.

    • Main Results:

    • No statistically significant differences were found between the CAI group and the control group in cocontraction, shuttle run, or agility hop tests.
    • P-values for the differences were .452, .680, and .902, respectively.
    • These results indicate that subjective CAI does not impair performance on these specific functional tests.

    Conclusions:

    • Subjective reports of chronic ankle instability do not correlate with objectively measured functional deficits in the tested population.
    • Athletes experiencing CAI may not exhibit performance limitations in standard functional assessments.
    • Further research employing more challenging functional performance tests is recommended to fully understand the implications of CAI.
