OBJECTIVES: To provide reference data for the Cumberland Ankle Instability Tool
(CAIT) and to investigate the prevalence and correlates of perceived ankle
instability in a large healthy population. DESIGN: Cross-sectional observational
study. SETTING: University laboratory. PARTICIPANTS:
Self-reported healthy
individuals (N=900; age range, 8-101y, stratified by age and sex) from the 1000
Norms Project. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Participants
completed the CAIT (age range, 18-101y) or CAIT-Youth (age range, 8-17y).
Sociodemographic factors, anthropometric measures, hypermobility, foot alignment,
toes strength, lower limb alignment, and ankle strength and range of motion were
analyzed. RESULTS: Of the 900 individuals aged 8 to 101 years, 203 (23%) had
bilateral and 73 (8%) had unilateral perceived ankle instability. The odds of
bilateral ankle instability were 2.6 (95% confidence interval [CI], 1.7-3.8;
P<.001) times higher for female individuals, decreased by 2% (95% CI, 1%-3%;
P=.001) for each year of increasing age, increased by 3% (95% CI, 0%-6%; P=.041)
for each degree of ankle dorsiflexion tightness, and increased by 4% (95% CI,
2%-6%, P<.001) for each centimeter of increased waist circumference. CONCLUSIONS:
Perceived ankle instability was common, with almost a quarter of the sample
reporting bilateral instability. Female sex, younger age, increased abdominal
adiposity, and decreased ankle dorsiflexion range of motion were independently
associated with perceived ankle instability.
