... Introduction Vibration is present everywhere in our environment. The two main characteristics of vibration are its frequency and magnitude (strength). Vibration is assigned to general categories based on frequency. Not all experts agree on the exact cut-off points for the categories, so any...

... Introduction Whole-body Vibration (WBV) concerns the transfer of relatively low frequency environmental vibration to the human body through a broad contact area. These frequencies are in the range of 0.5 to 80 Hz (ISO, 1). Transmission occurs through the feet when standing, the buttocks when...
