Postural stability and visual impairment: Assessing balance in children with strabismus and amblyopia
Fig 4
Mean score of three static tasks among the groups in different viewing conditions.
The diagram illustrates the difference in means of three different tasks the tandem task (A), the one-foot stand task (B) and the one-foot stand on a beam (C). The performance was measured as time to loss of balance in seconds with the eyes open (EO) and with the eyes closed (EC) among the different groups. Using the one-way repeated measures ANCOVA the amblyopia and the strabismus only group performed worse with their eyes closed compared to normal controls on the tandem and the one-foot stand (p<0.001), but this was not statistically significant on the one-foot stand on a beam (p = 0.25). The results presented in this figure are for males. Similar reduction in performance while the eyes were closed were also demonstrated in females. *Covariates appearing in the model are evaluated with the age value at 10.03 years. EO = eyes open. EC = eyes closed.
