Occupational exposure to vibration through the use of power- and pneumatic hand-tools results in cold-induced vasospasms, finger blanching, and alterations in sensorineural function. Collectively, these symptoms are referred to as hand-arm vibration syndrome (HAVS). Currently the International Standards Organization (ISO) standard ISO 5349-1 contains a frequency-weighting curve to help workers and employers predict the risk of developing HAVS with exposure to vibration of different frequencies. However, recent epidemiological and experimental evidence suggests that this curve under-represents the risk of injuries to the hands and fingers induced by exposure to vibration at higher frequencies (>100 Hz). To improve the curve, better exposure-response data need to be collected. The goal of this review is to summarize the results of animal and computational modeling studies that have examined the frequency-dependent effects of vibration, and discuss where additional research would be beneficial to fill these research gaps.

Introduction

Power Maxx Vibration Plate Manual Dexterity System

Workers that repeatedly use vibrating power- and pneumatic hand-tools are at risk of developing hand-arm vibration syndrome (HAVS). HAVS is characterized by cold-induced vasospasms in the fingers and hands that result in blanching of the skin, reductions in tactile sensitivity, pain, and changes in thermal thresholds. In addition, occupational exposure to hand-transmitted vibration may also contribute to reductions in grip strength and manual dexterity, muscle fatigue and atrophy and joint injuries^{, 2)}. In an attempt to protect workers from developing HAVS, the International Standards Organization (ISO) had developed a standard, ISO 5349-1, that contains a frequency-weighting curve to help workers and employers assess the risk of injury with exposure to vibration of different frequencies³⁾. This curve assigns the greatest weight to lower frequency vibration exposures (i.e., <16 Hz) and significantly less weight to higher frequency (>100 Hz) exposures, indicating that lower frequency exposures generate a greater risk of injury than higher frequency exposures. However, epidemiological and experimental evidence suggests that the risk of injury, particularly to the fingers and hands, is greatest with exposure to vibration at higher frequencies (>100 Hz). Thus, although the current weighting curve may accurately estimate the risk of injury to the hand-arm system, it appears to underestimate the risk of injury to the fingers and hands associated with exposure to higher frequency vibration.

In order to improve the standard, better exposure-response data need to be collected. Collecting exposure-response data in humans is difficult; single exposure studies may not accurately represent what happens to workers who can be repeatedly exposed to vibration over years, and collecting these types of data from workers is difficult because they may use different vibrating hand-tools over time, and it is difficult to precisely determine what their actual exposure is. Therefore, both animal surrogate and computational models have been developed to predict how vibration induces injuries to the hands and fingers, and to examine the frequency-dependence of these injuries. The goal of this paper is to review the results of the animal and computational modeling literature that have examined the frequency-dependent effects of vibration and to determine what additional research needs to be performed to improve the ISO standard.

Animal Models

A summary of papers utilizing animal models to examine the effects of vibration on peripheral vascular and nerve, and skeletal muscle is presented in Table 1. These studies used primarily rats and exposed them to either hind limb or tail vibration. Most of these studies examined the effects of vibration at a single frequency (usually 30–60 Hz, accelerations of approximately 2–7 g). These studies have provided some information regarding the frequency-dependence of vibration-induced injuries and demonstrate that exposure to vibration at frequencies greater than 20 Hz induces changes in peripheral vascular and neural, and skeletal muscle structure and function. The tissue alterations seen in multi-day studies are consistent with changes seen in workers diagnosed with HAVS, but more detailed investigations are needed to elucidate exposure-response patterns and mechanisms of injury^, .

Biodynamic response of the tail to sinusoidal vibration

Vibration Plate Soloflex

Experimental studies have demonstrated that the physical (i.e., biodynamic) response of the human hand-arm system is frequency dependent^, . The resonant frequency (i.e., the frequency or frequencies at which the oscillation of the tissues are amplified) of the hand-arm system as a complete unit is between 16 and 62.5 Hz. However, the resonant frequency of individual fingers is in the range of 150–300 Hz, and vibration at frequencies greater than 100 Hz is only transmitted to the tissues of the fingers and hands, and is not transmitted to the rest of the hand-arm system^, . Absorption of these higher frequency vibrations by the tissues of the fingers and hands may result in greater shear stress and strain in the local soft tissues, and it has been hypothesized that the increase in tissue stress and strain induced by these exposures may increase the risk of injury. Therefore, understanding the biodynamic response of the tissues to different vibration frequencies is critical for understanding how frequency may affect the risk of injury.

To test this hypothesis, a NIOSH research team modified the existing rat tail models of vibration-induced injury and assessed vibration transmissibility to the tail to determine how it compared to transmissibility of the human fingers. A diagram of the model can be seen in Fig. 1. Rats are confined in Broome style restrainers, and their tails are secured to a platform with elastic straps. A laser vibrometer measured vibration transmissibility to the tail at 1/3rd octave band frequencies between 31 and 500 Hz, and at constant accelerations of 1, 5 and 10 g. The graphs in Fig. 2 show vibration transmissibility to the tail is frequency- and location-dependent. At frequencies at or below 62.5 Hz, transmissibility is near 1, meaning that the tail is moving in unison with the platform. However, between 125 and 250 Hz, transmissibility significantly increases, meaning that the vibration is actually being amplified in the tail. The peak amplification, or resonant (natural) frequency, of the mid-portion of the tail is between 125 and 300 Hz. The resonant frequency is slightly shifted depending upon the acceleration used and the precise location of the measurement, but all animals tested displayed resonant frequencies in the same range. Human fingers also display a range of resonant frequencies (i.e., 125–300 Hz), depending on the location of the measurement and grip force used when the measurement was taken. The peak magnitude of the resonant frequency of the fingers isn’t as great in the fingers as it is in the tail, primarily because the mass and stiffness of the tail are less than those of the fingers. However because the frequency-dependent response of the fingers and tail are similar within this range, the tail can serve as a model for understanding the exposure-response relationship between vibration and tissue injury.

The frequency-dependent responses of vibration on soft tissues

Peripheral vascular morphology and function

A study was conducted using the NIOSH rat tail model of vibration-induced injury to assess the effects of frequency on peripheral vascular and nerve dysfunction. Rats had their tails exposed to vibration for 4 h/day for 10 days at 62.5, 125 or 250 Hz with a constant acceleration of 5 g (49 m/s² rms). Ventral tail arteries and nerves were collected from the mid-portion of the tail 24 h following the last exposure. This region of the tail was selected because the biodynamic response to vibration was different at these three frequencies, and thus by examining tissue in this region the effects of frequency could be assessed (Fig. 2).

Figure 3 shows the effects of vibration on morphology of the ventral tail artery. Vibration at 250 Hz resulted in a reduction in the size of the lumen and an increase in the thickness of the vascular smooth muscle (media layer), indicating that after exposure to vibration at 250 Hz the arteries were remodeled and narrowed. These changes in morphology were accompanied by an increase in immunostaining for nitrotyrosine, a marker of increased oxidative activity, and interleukin-6 (IL6), a factor involved in remodeling. Increases in oxidative stress and vascular remodeling often precede vascular dysfunction^, . Both the unweighted and ISO weighted accelerations are displayed on the x-axis of these figures. Based on the weighted accelerations, changes in vascular morphology should have been greatest at 62.5 Hz. But instead, vascular changes were greatest at 250 Hz, the resonant frequency in this region of the tail. These data are consistent with the hypothesis that frequencies that cause the greatest stress and strain on tissues will have the greatest effects. This does not mean other frequencies will not affect vascular function or morphology. However, these data suggest that the changes may occur more quickly or be more dramatic with exposure to vibration at or near the resonant frequency.

Photomicrographs of the ventral tail artery from rats exposed to restraint-control conditions or vibration for 10 days. The graphs show the (A) internal diameter and (B) thickness of the muscle walls from arteries collected from the rats in the various treatments. The x-axis displays frequency of the vibration along with the unweighted acceleration (U) and the ISO-weighted acceleration (W). The internal diameter of arteries was smaller in rats exposed to vibration at 250 Hz than in cage- or restraint-control rats (A: * less than cage or restraint controls, p<0.05). Vibration at 250 Hz also resulted in an increase in the thickness of the vascular smooth muscle (# greater than cage control, p<0.05). Data are expressed as group means ± sem.

These results indicate that there is time- and frequency-dependent adaptation of peripheral blood vessels to vibration because unlike the frequency effects noted at 10 d, Okada reported that a single exposure had an opposite response; the greatest reduction in tail blood flow was seen at low frequencies (i.e., 30 Hz, constant acceleration of 5 g). Other single day exposure studies examining the frequency-dependent effects of vibration on vascular function have shown that exposure of the tail to vibration between 30 and 800 Hz can cause morphological disruption of endothelial and smooth muscle cells and function in arteries^–. In the rat tail artery, vibration exposure for 9, 10 or 28 d, reduced the lumen diameter by vasoconstriction suggesting that there was structural and functional adaptation of the media smooth muscle layer. In the hind limb, intimal thickening and lumen obstruction in the arteries was reported for both 30 and 480 Hz after 30 d of exposure. Unfortunately the magnitude of this pathology is unclear because there was not quantification of the occurrence^, .

The different responses in these studies may be due to location specific vascular responses (i.e., tail versus hind limb). In studies utilizing the tail, the duration of the vibration differed and could account for the various outcomes. In addition, the methods for securing the tail to the platform, the location used for sample collection, and the length of the exposure were varied. The frequency-dependent biodynamic response of the tails and hind limbs to vibration in these studies is also unknown. What all these studies suggest, however, is that exposure to vibration frequencies over a wide range (30–800 Hz) can have detrimental effects on peripheral blood vessels. These findings are consistent with other research suggesting that the frequency-weighting curve may underestimate the risk of injury associated with exposure to frequencies > 100 Hz. There is a clear need for temporal examination because the frequency response of the naïve artery after a single exposure to vibration is not necessarily predictive of adapting arteries exposed for multiple days. Exposure to multiple and mixed frequencies should also be examined because workers developing HAVS are exposed to years of vibration at multiple frequencies.

Peripheral nerve morphology and function

The NIOSH study also measured frequency-dependent changes in peripheral nerve function using transcutaneous electrical stimulation. The tails were stimulated at 2 kHz with a transcutaneous electrical signal that assesses the function of large myelinated (i.e., Aβ) fibers. These fibers carry information from mechanoreceptors in the periphery to the central nervous system. Rats were tested prior to vibration exposures on the first day of the study and on day 9, prior to vibration exposure. Exposure to vibration at 62.5, 125 and 250 Hz resulted in a reduction in the perception threshold (i.e., an increase in sensitivity; Fig. 4). Increases in the sensitivity of nerves to various forms of stimulation are often a sign of injury. If nerve injury results in degeneration and loss of myelinated and unmyelinated axons the thresholds will increase. Okada et al., found that immediately following exposure to vibration at 30, 60 or 120 Hz, nerve conduction velocity was reduced, whereas there was not a significant reduction at 240, 480 or 960 Hz. These studies suggest that nerve function may be more sensitive, or have different frequency-dependent responses to vibration than arteries. The difference in the responses between these tissues may be due to delayed effects in the nerves or the difference between single versus multiple exposures.

Mean (± SEM) thresholds to transcutaneous electrical stimulation collected prior to vibration exposure on days 1 and 9 of a 10 day exposure regime (i.e. current perception threshold or CPT at 2000 Hz which primarily assesses the sensitivity of the large myelinated Aβ nerve fibers to stimulation). The x-axis shows the exposure frequency and the unweighted (U) and ISO-weighted (W) accelerations. On day 9 of the study, all rats exposed to vibration displayed a reduction in the CPT in comparison to controls, and day 1 measures. Data are expressed as the mean ± SEM CPT, * p<0.05).

Morphology of ventral tail nerves from control- and vibrated-rats also were analyzed in a number of studies^{, 24)}. In the NIOSH study, there was no change in the number of myelinated axons within the nerves, but there was a reduction in myelin thickness at 250 Hz at 10 days (Fig. 5A). There was also an increase in albumin staining in nerves collected from rats exposed to vibration at 250 Hz, which is indicative of vascular leaking and neural edema (Figure 5B). Govindaraju et al.²⁴⁾, found that a single exposure to tail vibration at 30, 120 or 800 Hz resulted in swollen and disrupted myelin, intraneural edema and dilated arterioles within the ventral tail nerve. The myelin damage and thickening observed immediately after a single 4 h vibration exposure, and 24 h post-vibration suggests that the reduction in myelin thickness after 10 days represents earlier demyelination/Schwann cell injury followed by remyelination^{, 24,} . Reductions in myelin thickness may allow an electrical signal to spread from axon to axon more quickly, thereby reducing thresholds for stimulation. However, changes in sensitivity to transcutaneous electrical stimulation were seen at all three vibration frequencies. These changes in sensitivity may have been the result of vibration-induced changes at the level of the sensory receptors, changes in ion channel numbers, or some other adaptive change in nerve physiology.

Impact vibration

Impulsive or percussive tools have fundamental frequencies in the 20–70 Hz range, generated by the impact or duty cycle. With each impact, a brief shock wave, msec in duration, is generated. The shock wave contains substantial power in the kHz frequency range. Average unweighted accelerations of 100 m/s² and peak accelerations ≥ 20,000 m/s² are common for percussive tools. Shock waves are less abundant and of lower magnitude in rotary tools. ISO 5349 frequency weighting minimizes the energy contribution in the higher frequency range (kHz), reducing accelerations to 7–20 m/s² for impact tools. Unfortunately, the prevalence of neural and vascular symptoms occur at higher percentages (risk) than predicted from ISO 5349^, . This discrepancy suggests that the high accelerations in the high frequencies maybe harmful and thus, should not be excluded from risk calculation by frequency weighting.

Studies of the tissue injury from impact vibration tools are surprisingly lacking. Recently, Govinda Raju et al. developed a rat tail model to assess the effects of impact vibration generated using a riveting gun. A single 12 min exposure produced immediate damage to nerve endings in the skin, mast cell degranulation and hypersensitivity to thermal stimulation. Four days later, the skin became hyposensitive to thermal stimulation, and the number of PGP 9.5 (a marker used to identify nerves) immunolabeled nerve endings had decreased (Fig. 6). Reduced thermal sensitivity and loss of feeling in the fingers are characteristic of established HAVS. Further animal studies are necessary to examine injury of the other soft tissues (e.g. artery, muscle, skin) and ascertain whether the injury is attributable to specific frequencies, especially in the kHz range, or the very high accelerations generated by percussive tools. Sinusoidal tail vibration experiments have shown that 60 Hz causes arterial injury in a 2-step process consisting of vibration-mediated vasoconstriction with smooth muscle cell blebbing and acceleration shearing off the blebs²⁴⁾. The blebs are large projections from the cells connected by slender stalks that are presumably readily broken by acceleration stress and strain. The rat tail impact vibration model has demonstrated rapid and severe tissue injury. These findings emphasize the need for an ISO regulation that considers the contribution of vibration energy from high frequencies when assessing risk to workers using percussive tools.

Immunostaining the rat tail skin with PGP9.5 antibodies reveals intact nerve endings in the sham control. Four days after a single 12 min exposure of the tail to riveting hammer impact vibration, fragmented destruction of the skin nerve endings is present. Arrows point to PGP9.5 immunostained nerves. Bar equals 35 μm.

Limitations of animal models

In humans, frequency and other factors such as the direction, the amplitude, the duration, the temperature, and the working posture and grip force on the tool contribute to the risk of developing HAVS. Animal studies can be used to examine the effects of vibration frequency, amplitude and temperature on the risk of developing a vibration-induced injury. The effects of duration of the exposure (both daily and cumulative) could be examined in animals. However, because it can take humans years to develop the symptoms of HAVS, it isn’t practical to attempt to replicate cumulative human duration exposures using animals. Animal models also cannot be used to examine the effects of posture, grip or force. In addition, animals are often restrained during exposures, and although restraint-induced stress and immobilization can contribute to changes in vascular and sensorineural responses^–, most studies control for these effects. However, even with these limitations, animal models do provide evidence that exposure to vibration at frequencies greater than 100 Hz pose a significant risk for injury to vascular and peripheral nervous system tissues. They also provide direct evidence linking the biodynamic response of tissue to injury and, therefore, provide a framework for understanding how frequency may affect the risk of injury in workers.

Computational models

Computational models of the fingers can be used to predict how factors contributing to HAVS, such as vibration frequency and amplitude, and applied force, contribute to the risk of injury. Both 2 dimensional (2D) and 3D finite element models have been developed to examine the responses of the finger to vibration^, . These models include the bone of the finger, the nail and use viscoelastic properties to define the soft tissues. These models predict that the resonant frequency of the finger is in the range of 125–300 Hz depending upon the amplitude and applied force used in the simulated exposure (Fig. 7). These findings are consistent with experimental studies that measure the frequency-dependent biodynamic responses of the fingers-hand to vibration. These studies also predict that tissue stress and strain is absorbed locally by the soft tissues at the resonant frequency, and that the absorption of vibration by these tissues induces high levels of stress and strain. Thus, the results obtained using mathematical and animal models are consistent with the hypothesis that exposure vibration frequencies that induce the greatest tissue stress and strain could induce changes in vascular and sensorineural function that morphology that lead to the development of HAVS.

Finite element simulations of the vibration effects on the soft tissues at the fingertip. A: The finite element fingertip model of the soft tissues, bone, nail, and vibration plate. B: The simulations show the frequency-dependent responses of the fingertip. The vibration penetrations into the soft tissue reached a maximum around 250–500 Hz; at very high frequencies (>1,000 Hz), the vibration concentrated only on the skin surface and did not penetrate deep into the soft tissues. As indicated by the key, red represents the greatest level of penetration into tissues and blue represents the lowest level of penetration.

Limitations of computational models

Modeling studies provide predictions about the potential tissue stress and strain endured by soft tissues during exposure to vibration. Computational models cannot account for postures, repetitive exposures, or the adaptive responses tissues can display in response to mechanical exposures. Current modeling, albeit state-of-the-art, is limited to the tissue level and, because of the enormous complexity, does not model the cellular and subcellular level of resonances and injury susceptibility. However, the results of the modeling studies taken with those of the animals studies provide strong evidence that vibration induces the greatest stress to tissues of the fingers at or near the resonant frequency and that these stresses and strains are associated with an increased risk of injury.

Summary and future directions

Studies performed using animal and computational models are consistent with human studies demonstrating that exposure to vibration frequencies between 100–300 Hz results in an increase in the biodynamic response of the fingers and demonstrate that there is a link between increased tissue stress and strain and the development of vascular and sensorineural dysfunction. These data also support epidemiological and experimental work demonstrating that the exposure to vibration at frequencies greater than 100 Hz may increase the risk of vascular and sensorineural dysfunction in the fingers and hands of workers exposed to these higher frequencies, and that the frequency weighting curve presented in the ISO 5349-1 standard may underestimate the risk of vibration-induced injuries to the systems at these higher frequencies^, . Additional studies examining the effects of other work- related and personal factors that can contribute to the risk of developing HAVS also would provide valuable information that could be used to improve the current standard, and to provide information to guide tool makers and manufacturers of personal protective equipment toward more effective designs that lower vibration exposure in the workplace.
