[The effect of vibrations in the early stages of embryogenesis on the postnatal motor and physical development of Wistar rats].

Abstract

The effect of vibrations on postnatal motor development and on the physical features of a breed of Wistar rats was investigated. The development of swimming abilities was divided into 6 stages, following KLAUS and HACKER (1978). Simultaneously, certain physical features were monitored. The results were evaluated with the help of the chi-squared homogenicity test. It was determined that there were no significant differences between the experimental animals and the controls.
