Abstract
Objective
To evaluate whether a battery of clinical assessments for acute lateral ankle sprain
(LAS) can be used to predict long-term recovery.
Design
Cohort study.
Setting
University biomechanics laboratory.
Participants
Individuals (N=82) were assessed using a clinical test battery within 2 weeks of incurring
a first-time LAS.
Interventions
Not applicable.
Main Outcome Measures
The clinical test battery included scores on the talar glide test (degrees), the anterior
drawer, talar tilt, figure of 8 for swelling (millimeters) and knee to wall (millimeters)
tests, and handheld goniometric range of motion (inversion, eversion, and plantarflexion
[in degrees]). Scores on the Cumberland Ankle Instability Tool taken 12 months after
the clinical test battery were used to classify participants as having chronic ankle
instability (CAI) or as being LAS copers.
Results
Forty percent of participants were designated as having CAI, with 60% being designated
as LAS copers. A logistic regression analysis revealed that a combined model using
scores from the talar glide, talar tilt, and anterior drawer tests in addition to
plantarflexion range of motion was statistically significant (P<.01) and correctly classified cases with moderate accuracy (68.8%). The final model
had moderate sensitivity (64%) and good specificity (72%).
Conclusions
The clinical tests used in this investigation have limited predictive value for CAI
when conducted in the acute phase of a first-time LAS injury.
