Chronic ankle instability (CAI) is often debilitating and may be affected by a
number of intrinsic and environmental factors. Alterations in neurocognitive
function and attention may contribute to repetitive injury in those with CAI and
influence postural control strategies. Thus, the purpose of this study was to
determine if there was a difference in attentional functioning and static
postural control among groups of Comparison, Coper and CAI participants and
assess the relationship between them within each of the groups. Recruited
participants performed single-limb balance trials and completed the CNS Vital
Signs (CNSVS) computer-based assessment to assess their attentional function.
Center of pressure (COP) velocity (COPv) and maximum range (COPr), in both the
anteroposterior (AP) and mediolateral (ML) directions were calculated from force
plate data. Simple attention (SA), which measures self-regulation and attention
control was extracted from the CNSVS. Data from 45 participants (15 in each
group, 27=female, 18=male) was analyzed for this study. No significant
differences were observed between attention or COP variables among each of the
groups. However, significant relationships were present between attention and COP
variables within the CAI group. CAI participants displayed significant moderate
to large correlations between SA and AP COPr (r=-0.59, p=0.010), AP COPv
(r=-0.48, p=0.038) and ML COPr (r=-0.47, p=0.034).
The results suggest a linear
relationship of stability and attention in the CAI group. Attentional
self-regulation may moderate how those with CAI control postural stability.
Incorporating neurocognitive training focused on attentional control may improve
outcomes in those with CAI.
