background: the primary objective of this study was to determine the association between risk factors and the prevalence of musculoskeletal disorder (msd) among auto repair mechanics in klang valley, malaysia. methods: overall, 191 mechanics from eight auto repair centers in klang valley, malaysia were stratified sampling as participants of this study. a modified version of the general standard...

The hand-arm vibration syndrome affects workers who perform tasks that generate vibration. Raynaud's phenomenon and sensory impairment of the fingers are the predominant effects. A history of hand-arm vibration (HAV) exposure in a patient with these symptoms should alert the physician to the diagnosis. Referral to a special clinic or hospital department for multiple clinical tests is required t...

Sensory stimulation of wrist musculature can enhance stability in the proximal arm and may be a useful therapy aimed at improving arm control post-stroke. Specifically, our prior research indicates tendon vibration can enhance stability during point-to-point arm movements and in tracking tasks. The goal of the present study was to investigate the influence of forearm tendon vibration on endpoin...

OBJECTIVES The purpose of this study was to compare various effects on the hand-arm system of vibration exposure from a chipping hammer and a grinder with the same frequency weighted acceleration. Grip and push forces were measured and monitored during the exposure. The various effects were: muscle activity (measured with surface electrodes), discomfort ratings for different parts of the hand-a...

Abstract: Wind load is the key and sensitive for tower structure but national standards tend to think that level stiffness change of cup type transmission tower is uniform along the height. The structure stiffness change of cup type transmission tower was simulated innovatively and found its nonuniformity. The result shows that the structural stiffness uniformly changes along the height when th...

Proprioceptive signals coming from both arms are used to determine the perceived position of one arm in a two-arm matching task. Here, we examined whether the perceived position of one arm is affected by proprioceptive signals from the other arm in a one-arm pointing task in which participants specified the perceived position of an unseen reference arm with an indicator paddle. Both arms were h...

UNLABELLED The internationally accepted limit values and the health effects of hand-transmitted vibration exposure have been described extensively in the literature from temperate climate countries but not from a tropical climate environment. OBJECTIVES We conducted a systematic review of the health effects of hand-transmitted vibration exposure in tropical countries to determine the characte...
