Hand-arm vibration effects on performance, tactile acuity, and temperature of hand

Study of the effect of hand-arm vibration on hand grip strength

Introduction: Musculoskeletal injuries are one of the most common causes of work-related illnes, reimbursement and absence among workers in working environments throughout the world. Among various factors, exposure to vibration is one of the main causes of these injuries. The aim of this study was to investigate the effect of key factors on the occurrence and exacerbation of the effects of expo...

Hand-arm vibration syndrome.

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...

Wood Density Impact on Hand-Arm Vibration

Nacrtak Despite technological advancements in machinery for timber harvesting, chainsaws are fre­ quently used in forest operations. In Austria 85% of the wood volume harvested (15 million m3) are cut by chainsaws. The two most frequently documented ergonomic threats during motor manual felling include exposure to noise and vibration. This paper presents the results of exposure to hand-arm vibr...

Hand-arm Frequency-weighted Vibration Effects on Tactility

This study reports results of an investigation into the short-term effects of power hand tool vibration on deep sense tactile sensitivity. Five subjects operated a simulated hand tool using a 30 s / 30 s work~rest duty cycle. The handle vibrated at 1S0 5349 weighted acceleration of 8 m / s 2, for frequencies of 20 Hz, 80 Hz, and 160 Hz, in three orthognal directions. A no-vibration condition wa...
