Background
This pilot study aimed to explore the impact of visual, auditory and vestibular dysfunctions on the postural balance performance in adults with intellectual disabilities. Additionally, a comparison was made between the subjects with intellectual disabilities and a control group concerning static and dynamic balance tasks.
Method
Thirty adults with intellectual disabilities and 25 control subjects received a postural balance assessment. Additionally, the experimental group was subjected to a visual, auditory and vestibular screening.
Results
The experimental group performed significantly worse and/or showed more sway compared to the control group for all balance tasks (p < .01) except the timed up and go test. Within the experimental group, a significant positive correlation (rs(24) = 0.513, p = .007) was observed between the number of failed sensory screening items and the number of failed balance tasks.
Conclusions
These findings suggest significant involvement of peripheral sensorial deficits in the balance problems that people with intellectual disabilities often experience.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
