Introduction and Purpose: Deficits in proprioception and postural control are recognized as key contributors to the progression and persistence of chronic ankle instability (CAI). This study aimed to investigate the immediate effects of a dual-task (cognitive–neuromuscular) rehabilitation protocol on static and dynamic postural control and proprioception in male and female athletes with CAI.
Methods: This single-blind randomized controlled clinical trial was conducted on 44 male and female participants with chronic ankle instability (CAI), aged 18–25 years. Participants were systematically randomized allocated to either a dual-task training group (n = 22) or a control group (n = 22). The intervention group completed a single 30-minute session of cognitive–neuromuscular dual-task training. The primary outcomes were static and dynamic postural control, assessed using the Biodex Balance System. The secondary outcome was ankle joint proprioception, evaluated using an electrogoniometer.
Results: Paired-samples t-tests demonstrated significant improvements in static and dynamic postural control and proprioceptive error from pre- to post-intervention in the dual-task group (all P < 0.001), whereas no significant changes were observed in the control group (P > 0.05). The results of the mixed analysis of variance test with repeated measures on the interactive effect (time × group) showed that there was a significant difference between the dual task group and the control group in improving static postural control of the overall index (P <0.001, ηp2=716), dynamic postural control of the overall index (P <0.001, ηp2=420), and the proprioception error of 10 degrees of dorsiflexion (P <0.001, ηp2=528).
Conclusions: A single session of dual-task (cognitive–neuromuscular) training produced immediate improvements in static and dynamic postural control and proprioception in athletes with chronic ankle instability. These findings support the incorporation of dual-task training as a complementary rehabilitation strategy for athletes with chronic ankle instability.
