Table 4.
Percent reduction of the total vibration on tools (negative value: the glove amplifies the vibration transmitted to fingers; positive value: the glove reduces the vibration transmitted to fingers). G-A – Gel Glove; G-B – Air Bladder Glove; G-C – Air Bubble Glove; G-D – Neoprene Glove. All tools are cited from [28,34–36]
