Summary
Cognitive tasks did not significantly impact postural control in individuals with Chronic Ankle Instability (CAI). Dual-task performance was not worse in CAI groups compared to healthy controls, though results varied.
Area of Science:
- Biomechanics and Motor Control
- Neuroscience
- Sports Medicine
Background:
- Chronic Ankle Instability (CAI) is associated with altered gait, proprioception, and postural control.
- Neurophysiological changes, including during dual-task situations, are observed in individuals with CAI.
- Previous research on cognitive tasks affecting postural control in CAI is inconclusive.
Approach:
- A systematic review and meta-analysis of 9 studies was conducted.
- Searched 4 electronic databases (PubMed, MEDLINE, CINAHL, SPORTDiscus) from inception to October 2022.
- Included studies comparing postural control or gait in control and CAI groups under dual-task conditions.
Key Points:
- Meta-analysis of 5 studies (10 effects) found a significant effect in the mediolateral direction for the control group (Fisher's Z = 0.732, p = 0.029) with high heterogeneity.
- No significant differences in dual-task performance were found within the CAI group or when comparing CAI to control groups.
- Cognitive loading did not affect postural control, except in the mediolateral direction for the control group.
Conclusions:
- Cognitive tasks generally do not impair postural control in individuals with Chronic Ankle Instability.
- Variability in dual-task performance may stem from task difficulty and the heterogeneity of CAI populations.
- Further research is needed to clarify the complex interplay between cognitive load and postural control in CAI.
