Attention is associated with postural control in those with chronic ankle instability

Area of Science:

• Sports Medicine
• Neuroscience
• Biomechanics

Background:

• Chronic ankle instability (CAI) is a prevalent condition often linked to intrinsic and environmental factors.
• Neurocognitive deficits, particularly in attention, may exacerbate CAI by influencing postural control and leading to recurrent injuries.

Purpose of the Study:

• To investigate differences in attentional function and static postural control among individuals with CAI, 'copers,' and healthy controls.
• To examine the relationship between attentional function and postural control within each participant group.

Main Methods:

• Participants (n=45) were divided into three groups: Comparison, Coper, and CAI (15 per group).
• Attentional function was assessed using the CNS Vital Signs (CNSVS) computer-based test, focusing on Simple Attention (SA).
• Static postural control was evaluated using single-limb balance trials, measuring Center of Pressure (COP) velocity (COPv) and range (COPr) in anteroposterior (AP) and mediolateral (ML) directions.

Main Results:

• No significant differences in attentional function or COP variables were found among the Comparison, Coper, and CAI groups.
• Significant correlations were observed between Simple Attention (SA) and postural control variables (AP COPr, AP COPv, ML COPr) specifically within the CAI group.

Conclusions:

• A linear relationship exists between attentional self-regulation and postural stability in individuals with CAI.
• Attentional control may play a moderating role in how individuals with CAI manage their postural stability.
• Integrating neurocognitive training focused on attentional control could be a beneficial therapeutic strategy for managing CAI.
