In the search of new strategies to improve the quality of life of Parkinson's disease patients, recent work has reported an amelioration of Parkinsonian symptoms using Whole Body Vibration (WBV). A double-blinded, placebo controlled design was used to evaluate the effect of a 12 WBV sessions-programme on a number of motor and clinical tests in 23 Parkinson's disease patients. Patients were assi...

BACKGROUND whole-body vibration training may improve neuromuscular function, falls risk and bone density, but previous studies have had conflicting findings. OBJECTIVE this study aimed to evaluate the influence of vertical vibration (VV) and side-alternating vibration (SV) on musculoskeletal health in older people at risk of falls. DESIGN single-blind, randomised, controlled trial comparing...

The recent earthquakes in Christchurch led to the redevelopment of the University of Canterbury’s Seismic Equipment Laboratory (SEL). The SEL facility will involve the testing of building structures subject to simulated static and dynamic displacements from earthquakes, with a reaction wall and floor used to exert loads by way of hydraulic actuators on test specimens, and shaker tables used to ...

A series of wind tunnel model tests and theoretical analyses were conducted to investigate torsion excitation, response and vibration suppression of wind-excited buildings. An aeroelastic model for pure torsion vibration was developed and the aeroelastic test results were compared with those obtained by other Wind tunnel test techniques. The comparison and practice indicated that this type of m...

in this study a series of ambient vibration tests on the triple ferrocement elevated water tanks with 150 cubic meters volume, is carried out. in order to verify the dynamic characteristics of full, half-full and one full tanks (mass eccentric system), the different arrangements of sensors are used. the effects of base rotation are also considered in the tests. natural frequencies and mode shap...

INTRODUCTION The individual and combined effect of occupational noise and vibration exposures, on workers' health has not been thoroughly investigated. In order to find better ways to prevent and manage workers' headache, this study aimed to investigate the effects of occupational noise and vibration exposure on headache/eyestrain. METHODS We used data from the fourth Korean Working Condition...

BACKGROUND The Department of Trade and Industry set up a contract to examine miners and ex-miners claiming compensation for hand-arm vibration syndrome (HAVS). They had been exposed to hand-transmitted vibration. Over 100,000 have now been examined using sensorineural tests as part of that process. AIMS The purpose of this paper was to examine the internal consistency of the vibrotactile thre...
