Postural Control Deficits in Chronic Ankle Instability

Hypothesis
We hypothesized that gender would not influence TTB measures of postural control and that a mixed-gender group with CAI would display TTB deficits compared to healthy controls.
Conclusion
Postural control deficits as assessed with TTB measures were present in the CAI group compared to the control group when balance testing was performed with eyes closed, but not eyes open.
Supporting Evidence
- The CAI group demonstrated significant deficits in comparison to the control group with eyes closed.
- Significantly lower values were found for the mean of TTB minima and the standard deviation of TTB minima in the AP direction.
- The CAI group had significantly more failed trials compared to the control group during the eyes closed condition.
Takeaway
People with chronic ankle instability have trouble balancing, especially when they can't see, which makes it harder for them to stay upright.
Methodology
This case-control study involved 32 subjects with self-reported CAI and matched healthy controls performing single-limb stance trials on a forceplate.
Limitations
The study may have limited generalizability due to the relatively small and homogeneous sample.
Participant Demographics
18 males and 14 females with self-reported CAI, matched with healthy controls.
