Whole-body vibration and disorders of the spine
International Archives of Occupational and Environmental Health, 1987This cross-sectional study is based on interviews and medical examinations of 352 operators of earth-moving machines who had been exposed to whole-body vibrations for at least three years. In addition, available X-rays showing different parts of the spines of 251 machine operators who had been exposed to vibration for at least ten years were used for ...

The Measurement of Whole Body Vibration in the Workplace
American Industrial Hygiene Association Journal, 1985A measurement system was developed to assess the amount of whole body vibration to which workers are exposed during routine operation of machinery in an industrial setting. This system is discussed in terms of plant structural design, production levels, direction and intensity of vibrational forces, measuring equipment, proper measurement technique and

Psychophysical Assessment of Whole-Body Vibration
Human Factors: The Journal of the Human Factors and Ergonomics Society, 1971Using the methods of magnitude estimation and intensity matching, curves of equal subjective vibration intensity were constructed over the frequency range from 3.5 to 20 Hz. Twenty subjects made magnitude estimations of the intensity of vibration at 0.08, 0.16, 0.24, 0.40, 0.48, and 0.56 gz with vibration at 0.32 gz serving as a standard.

Electrocorticogram during whole body vibration
Electroencephalography and Clinical Neurophysiology, 1966Abstract Studies in the conscious monkey have shown that during low frequency vibration (4.5–19.5 c/sec) rhythms at the vibration frequency appear intermittently in the ECoG. These rhythms are commonly dissociated between recordings from different but adjacent areas of the cortex and augment with changes in the orientation of the head. The rhythms do

Whole Body Vibration and Dynamic Restraint
International Journal of Sports Medicine, 2008The purpose of this study was to identify changes due to whole body vibration in peroneus longus (PL) activation following ankle inversion perturbation. Participants were 22 (age 22.1 +/- 1.8 yrs, ht 168.8 +/- 8.2 cm, mass 65.5 +/- 11.2 kg) physically active male and female students with no recent history of lower extremity injury.

Whole-body vibration in the reduction of the cellulite
Journal of Cosmetic and Laser Therapy, 2018Evaluate the effects of the whole body vibration in improving of cellulite in the women's gluteal region.Controlled clinical trial performed with 42 women, with cellulite in the gluteal region, detected by means of clinical examination. After evaluation, the women were divided into two groups: Whole-Body Vibration (WBV_G) and control (C_G).

Current Sports Medicine Reports, 2008
In recent years, it has been suggested that exercise using whole body vibration (WBV) platforms may increase muscle activity and subsequently enhance muscle performance in both acute and chronic conditions. WBV platforms produce frequencies ranging from 15-60 Hz and vertical displacements from ~1-11 mm, resulting in accelerations of ~2.2-5.1 g.

Human Response to Whole-Body Vibration
Perceptual and Motor Skills, 1972Research concerning several types of human response to whole-body vibration is reviewed and evaluated. Major emphasis is on two categories of behavioral research, subjective judgments of vibration intensity and the effects of vibration on human performance.

Whole Body Vibration, Cognition, and the Brain
2018Scientific interest into the impact of vibrating stimuli goes back to the beginning of the 20th century when Hamilton (1918) described an unusual disease in limestone cutters. After the introduction of air-hammers (main vibrations of 75 Hz during 8–10 hours per shift), the majority of the cutters developed vibration-induced white fingers with altered ...
