“…Changes in finger touch sensation threshold are found among dentists and dental technicians who commonly use tools with vibration levels exceeding 1000 Hz (Lundström and Lindmark, 1982). The reduction in grip strength associated with HAV exposure has been well documented in short-term studies where participants use vibrating hand tools as well as from epidemiological studies of more long-term effects (Widia and Md Dawal, 2010; Widia and Md Dawal, 2011; Gaidhane and Patil, 2012; Nyantumbua et al, 2007). Vibration dose, the product of vibration level and exposure time, is a critical factor for developing HAVS and a strong relationship has been shown between the severity of HAVS and the exposure time (Bernard et al, 1998; Bovenzi, 1998).…”

Falls from mobile equipment are reported at surface mine quarry operations each year in considerable numbers. Research shows that a preponderance of falls occur while getting on/off mobile equipment. Contributing factors to the risk of falls include the usage of ladders, exiting onto a slippery surface, and foot or hand slippage. Balance issues may also contribute to fall risks for mobile equipment operators who are exposed to whole-body vibration (WBV). For this reason, the National Institute for Occupational Safety and Health, Office of Mine Safety and Health Research conducted a study at four participating mine sites with seven haul truck operators. The purpose was to ascertain whether WBV and hand-arm vibration (HAV) exposures for quarry haul truck operators were linked to short-term decreases in performance in relation to postural stability, touch sensation threshold, and grip strength that are of crucial importance when getting on/off the trucks. WBV measures of frequency-weighted RMS accelerations (wRMS) and vibration dose value (VDV), when compared to the ISO/ANSI standards, were mostly below levels identified for the Health Guidance Caution Zone (HGCZ), although there were instances where the levels were within and above the specified Exposure Action Value. Comparably, all mean HAV levels, when compared to the ISO/ANSI standards, were below the HGCZ. For the existing conditions and equipment, no significant correlation could be identified between the WBV, HAV, postural stability, touch sensation threshold, and grip strength measures taken during this study.

“…Long term exposure to hand-arm vibration has been shown to result in occupational health issues such as numbness and decreased grip strength [141], [142]. A continuous usage of vibratory powered hand tools can lead to excessive grip force, which may elevate the chance for muscle fatigue and grip strength decrement, as reported by Widia and Dawal [143]. Average grip force increased by 27% (from 25.3 N without vibration to 32.1 N for vibration) at vibration frequency of 40 Hz [144].…”

Hand is made up of bones, tendons, ligaments, nerves and blood vessels that can be easily debilitated and injured if the hand tool is not design ergonomically. Recently researchers have examined the effects of individual, environmental and occupational factors on hand grip strength. However, information on the influence of hand tool design on hand grip strength is still lacking. The aim of this paper is to provide a comprehensive review of factors influencing hand grip strength focusing more towards hand tool design factors. The authors searched the journal articles, book and guidelines from the online databases of Google Scholar, ScienceDirect and Pubmed. Fourteen factors includes handle diameter, handle length, handle orientation, handle shape, handle material, handle flange, handle inter distance/grip span, grip method, tool weight, tool center of gravity, tool sharpness, trigger type and size, spring stiffness as well as vibration exposure were found to have significant effect on the hand grip strength. This review identified that the handle diameter is the most significant factor for hand grip strength.

“…The rationale of this study was established from occupational hand arm vibration knowledge for epidemiological methods used to identify and analyze the health cause-effects induce in a work related with vascular, neurological and musculoskeletal disorders at workplace. Hence, its principle method is to define a subjective and objective measures linked with the development of hand arm vibration syndrome (HAVS) which has a significant element for HTV in developing the health cause-effect of hand arm vibration exposure in Malaysia [9,10,11,12,13]. The investigation of hand arm vibration exposure to the health cause-effect associated to the HAVS is becoming a major interest for both human factor and occupational health in conducting their research study [11,12,13].…”

“…Furthermore, most of the established hand-transmitted assessments are not deeply revealing the health cause-effect due to complicated exposure dose response relationship during the data analysis process either by linear or neural network methods [25,26,27,28]. The evaluations of the health cause-effect are the important components for predicting the HTV exposure prevalence to HAVS, particularly for Malaysian research that seeks to construct a cause-effect relationship model between HTV risk measures and HAVS health consequences [9,11,13]. Su et al (2014) stated that the presence of the symptoms associated to HAVS and the high level of daily vibration exposure in the tropical environment could contribute to the initial factor for controlling HTV hazard based on work activity.…”

Prolonged exposures to hand-transmitted vibrations from grass-cutting machines have been associated with increasing occurrences of signs of occupational diseases related to the hand-arm vibration syndrome (HAVS). However, there are no specific processes available that cover the subjective and objective health cause-effects of the hand arm vibration risk factors during onsite operations. The objectives are (1) to measure the health subjective and objective risks during normal working conditions among hand-held grass-cutting workers and (2) to determine the significant correlation of the subjective and objective measurement variables of the Hand Arm Vibration Exposure Risk Assessment (HAVERA) on hand arm vibration symptoms and disorders. The study was conducted in two stages: evaluation of the HAVERA variables and development of the health prediction cause-effect model of the HAVERA process using multiple linear regressions and feed forward neural network programming. In the onsite measurement, the daily vibration value depicted an exceeded exposure action value of 2.5 m/s2 for both hands; and experiences of any finger colour change were claimed by 80% of the 204 subjects. This shows that HAVERA process provided a good indication of HAVS which are reported as vascular, neurological and musculoskeletal disorders. In the right and left hand prediction model development, the results demonstrated a higher reliability performance as compared to the linear model for hand grip strength and hand numerical scoring assessment. The prediction of the HAVERA model using the neural network method has been developed for monitoring health conditions due to hand-transmitted vibrations among hand-held grasscutting workers in Malaysia.
