2. 1. Attenuation of hand-held machine vibrations. Application of non-linear tuned vibration absorber

   Author : Hans Lindell; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Impact machine; Hand-arm vibration; High frequency vibration; ATVA; Nonlinear tuned vibration absorber; White finger; HAVS; Transient vibration; Auto Tuned Vibration Absorber; Vibration dynamics; ISO 5349;

   Abstract : Vibration injury in the hand-arm system from vibrating hand-held machines is one of the most common occupational health injuries and causes severe and often chronic nerve and vascular injuries to the operator. The objective with this study is to contribute to reduce hand-arm vibration injuries, first by developing methods of redesigning machines that will lower their vibration level and second to study how high frequency vibrations (HFV) above 1250 Hz effect the finger tissue which are not included in the current standard for risk evaluation.

4. 2. Health effects from occupational hand-arm vibration

   Author : Per Vihlborg; Pål Graff; Sverre Wikström; Karim Makdoumi; Magnus Svartengren; Örebro universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hand-arm vibration; Raynaud’s phenomenon; vibration white finger; carpal tunnel syndrome; acute vibration exposure; neuropathy;

   Abstract : Hand-arm vibration (HAV) is a common occupational exposure in Sweden and worldwide that causes both acute transient effects and persistent hand-arm symptoms. The health effects include vibration-induced Raynaud’s phenomenon, neuropathic symptoms, carpal tunnel syndrome (CTS), and musculoskeletal disorders. READ MORE

5. 3. Vibration-induced muscle injury in the hand - experimental and clinical studies

   Author : Lars Necking; Malmö Handkirurgi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatologi; Surgery; muscle morphometry; intrinsic hand muscle; muscle strength; muscle injury; hand weakness; Vibration exposure; hand-arm vibration syndrome; orthopaedics; traumatology; Kirurgi; ortopedi;

   Abstract : Exposure to vibration is known to cause vasospastic white fingers and/or sensorineural symtoms such as numbness and tingling in fingers and/or musculoskeletal disorders such as reduction in muscle force, fatigue and reduced endurance. Classifications for the vasospastic and sensorineural symptoms are established. READ MORE

6. 4. Effects of cold and hand-arm vibration on the peripheral neurosensory and vascular system : an occupational perspective

   Author : Daniel Carlsson; Jens Wahlström; Tohr Nilsson; Erik Nordh; Hans Pettersson; Tiina Ikäheimo; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hand-arm vibration; Raynaud’s phenomenon; paresthesia; sensation of cold; hand-arm vibration syndrome; quantitative sensory testing; cold sensitivity; cold; cold exposure; frostbite; Sweden; cold injury; military; Occupational and Environmental Medicine; arbets- och miljömedicin;

   Abstract : Background In Swedish working life, exposure to cold and exposure to hand-arm vibration (HAV) are two common health hazards. Health effects of HAV in the neurosensory, vascular and musculoskeletal systems are collectively denoted hand-arm vibration syndrome (HAVS), and have been thoroughly studied. READ MORE
