## 7 Conclusions
As mentioned earlier, in terms of hand protection against the transmission of vibrations from exciting sources, only gloves are currently available [23; 45]. Some states provide, within their legislation, conditions for when occupational illness at work is caused by the employer's noncompliance with the law (exposure time, protective equipment), allowing the injured person to ask for compensation (financial or material). Other research instead focuses on developing and evaluating a new methodology for the assessment of finger-borne vibrations, including the vibration test facility and measurement protocol [18; 43; 48; 49; 57; 71; 72; 74; 76; 77; 78; 82]. Another strategy is to develop a finite-element model of the proximal finger system to help evaluate measurement methods and validate physical models of the fingers. Yet another research direction involves performing various measurements on human participants to study the effect of aspects of finger-transmitted vibrations [35; 52; 88] in relation to VWF and be used for finger model validation. In conformity with [39], only one postures was available in the case of a rotatable main handle. The postural effect was evaluated objectively with electromyography and a force-sensing resistor-based force glove. Other studies instead focus on the development and validation of an artificial finger model to serve as an experimental test bench for the evaluation of finger-transmitted vibrations [59]. This will reproduce both the loading and vibration behaviors of the human finger system. The studies based on Ref. [33] use the results to test the artificial finger model, evaluate its ability, and measure the effect of using anti-vibration gloves, which will lead to the development of new materials for gloves; this line of research has been validated by [23], among others. In conclusion, this review paper aimed to show that vibrations are part of people's professional life, especially in certain work environments, where prolonged exposure to them must be avoided (mining, construction) [62; 88]. All the studies carried out so far have demonstrated and validated the fact that, at low frequencies--below 25 Hz--vibrations are transmitted more than at higher frequencies, but there is also a limit of up to 250 Hz, above which vibrations are strongly felt. Likewise, posture, grip strength, sex, physical condition, and other factors can influence their transmission. In this sense, new methods of approaching their measurements and testing the limit threshold are being developed (in compliance with the SR EN 5349/2003 standard). Improvements are also being made to the materials from which protective gloves are created, which are currently the only method of reducing the transmission of vibrations further along the forearm and fingers [68; 75]. Specialty studies show that there are more and more mathematical models for equipment, which theoretically show how these products could minimize the transmission of vibrations along the arm. The only drawbacks of research in this field are the experimental realization and validation of theoretical results regarding the protective equipment. In addition, such works are, unfortunately, extremely rare to come by.
