Postural control (PC) requires the interaction of the three sensory systems for a
good maintenance of the balance, and in blind people, lack of visual input can
harm your PC. Thus the objective is to perform a literature review concerning
role of sight in the maintenance of PC and the adaptation of brain structures
when vision is absent. Studies were searched from Pubmed, and EMBASE that
included individuals with congenital blindness. Articles studying person with
acquired blindness or low vision was excluded from this review. 26 out of 322
articles were selected for review, and we found that 1) blind individuals exhibit
PC deficits and that is compensated by the intensification of the remaining
systems; 2) Neuroplastic adaptation occurs throughout the entire cerebral cortex;
and 3) Sensorimotor stimulation and transcranial direct current stimulation seem
to be a rehabilitation strategy. According to this review, the findings suggest
that improved remaining sensations in the presence of adaptations and
neuroplasticity, does not translate into better postural control performance.
Regarding rehabilitation strategies, more studies are needed to show which
therapeutic modality best contributes to postural control.
