Abstract

Background

Individuals
with chronic ankle instability (CAI) demonstrate altered ankle
kinematics during running compared to uninjured individuals; however,
little is known about differences between individuals with CAI and those
who recover successfully from an index sprain (copers).

Methods

Thirty-two
young male athletes with prior ankle sprain were investigated, eighteen
with CAI and fourteen copers. Instrumented running analysis was
performed on a treadmill at two velocities: moderate (2.63 ± 0.20 m/s,
rate of perceived of exertion = 14/20); and high velocity
(3.83 ± 0.20 m/s). Mean ankle kinematics and stride-to-stride
variability were analyzed applying the statistical parametric mapping
method.

Results

At
both running velocities, no statistically significant differences in
mean ankle kinematics were observed. At high running velocity, athletes
with CAI demonstrated significantly increased frontal plane variability
at 17-19% of the running gait cycle (p = 0.009). Additionally, large
between-group effect sizes (Hedges’ g ≥ 0.8) may potentially indicate
increased frontal plane variability during initial contact and terminal
swing, as well as decreased variability in sagittal plane at 34-35% in
CAI. A similar tendency existed at moderate velocity, with large effect
sizes indicating decreased dorsiflexion at 75-89% in CAI, as well as an
increased frontal plane variability at 16-25%, and 97-99%.

Discussion

Compared
to copers, individuals with CAI demonstrate increased variability of
ankle kinematics - mainly in the frontal plane and particularly during
stance phase - while mean ankle kinematics seems minimally affected.
Increased ankle variability at high running velocity may best reflect
persisting sensorimotor control deficits in athletes with chronically
instable ankles.
