Although atypical motor behaviors have been associated with autism, investigations regarding their possible origins are scarce. This study assessed the visual and vestibular components involved in atypical postural reactivity in autism. Postural reactivity and stability were measured for younger (12-15 years) and older (16-33 years) autistic…

The study sought to provide norms for a simple test of visual perception of verticality (subjective visual vertical). The study was designed as a cohort study with a balanced design. The setting was the Rehabilitation Department of a University Hospital. Twenty-two healthy adults, of 23-58 years, 11 men (three left handed) and 11 women (three left…

Analyzed postural oscillations in six-, eight-, and 10-year-olds in four visual and two somatosensory conditions. Found that children were more stable with than without vision and more stable with a normal than with an altered support surface. Overall, there was no effect of age. The relative influence of peripheral and central vision on postural…

Compared the postural responsiveness of seven-, eight-, and nine-month-old infants. Results indicated greater use of optic flow for postural control after a self-produced locomotor experience. Infants with endogenous (creeping) or artificial (walker) self-produced locomotor experience responded to portions of the optic flow field, whereas…
