Abstract
In congenital disorders of the inner ear and cerebellar hypoplasia, muscle tone is considerably reduced in patients during the early phase of these diseases, and a persisting floppy phase and considerable delays in head and neck stability and the timing of first walking are seen in such babies.
Patients with congenital disorders of the inner ear are often misdiagnosed as cerebral palsy development because the symptoms are similar in the early stage.
In acquired disorders of the inner ear, such as meningitis, balance function and motor development could degenerate due to sudden onset of labyrinthine disorder in a normally delivered new born. The symptoms may be too severe to be mistaken a serious brain disorder. Visual disturbances have a considerable impact on the development of motor function. Children with congenital blindness start walking around 2 years of age, a delay of approximately 1 year.
Moreover, various congenital brain diseases such as cerebellar and cerebellar anomaly or meningitis cause serious delay in motor development.
