VIBRATION EFFECTS ON SETTING PREGNANT-WOMEN - SUBJECTS OF VARIOUS MASSES

An electrical simulation of a mechanical model of a 60 kg pregnant wom an subjected to horizontal and vertical vibrations has been investigat ed by using a computer software package (MICRO-CAP II). The results ha ve shown that mechanical vibrations affect the body segments different ly based on their location, the kind of vibration and pregnancy develo pment. The vibrations' effect on the body varies from segment to segme nt and a lady driver is affected by vibrations more than a lady passen ger, Horizontal vibrations affect body segments (lower arm, upper arm, head, thorax, torso, cervical spine, thoracic spine and lumbar spine) more than vertical vibrations, while the thorax is affected by vertic al vibrations more than horizontal vibrations.
