Whole-Body Vibration
Published in Neil J. Mansfield, Human Response to Vibration, 2004
The most commonly reported health effect of whole-body vibration is back pain. Indeed, back pain is the focus for the rest of this section. Despite this, other types of health effects have been observed. These include sciatica, digestive disorders, genitourinary problems, and hearing damage (Griffin, 1990). Portuguese researchers have reported links between low frequency noise and whole-body vibration with a variety of disorders, collectively termed vibroacoustic disease (e.g., Castelo Branco and Rodriguez, 1999; Castelo Branco, 1999). These include thickening of cardiac structures and neurological and vascular disorders. Despite the name of the condition, the greatest contributor to risk is considered to be large-pressure-amplitude (≥90 dB SPL), low-frequency (≤500 Hz) noise and not whole-body vibration as described in this book. One might argue that high-intensity, short-duration impacts that can cause trauma of the internal organs is a form of whole-body vibration. Such topics fall within the remit of crash research and are beyond the scope of mainstream whole-body vibration research. At the other extreme, low-intensity, long-duration vibration might cause annoyance leading to elevated blood pressure and other stress-related symptoms.
Effects of infrasound on health: looking for improvements in housing conditions

Alves-Pereira and Castelo Branco [35] stated that, in sectors such as aeronautics, vibroacoustic disease (VAD) is a pathology marked by the action of infrasound and low-frequency sounds, where there is abnormal growth of collagen and elastin without any inflammatory process. This condition can be observed by electroencephalography (EEG) in the blood vessels, cardiac structures, lungs, kidneys and trachea.
