Impact of lightweight and conventional jackhammers on the operator

The study

Campbell-Kyureghyan N, Singh G, Otieno W, Cooper K (2012) Impact of lightweight and conventional jackhammers on the operator. Work 41: 4180-4184

In examining the potential benefits of lightweight (27 kg) vs. conventional (40 kg) jackhammers, researchers measured forearm EMG amplitude and vibration characteristics among experienced jackhammer operators while small <1 m2 sections of asphalt and concrete pavement were broken up. Researchers found that both lightweight and conventional jackhammers produced similar vibrations measured at the hand (9.7 m/s2 weighted RMS accelerations), but that EMG activity in major upper body muscle groups were reduced, in some cases by nearly 50%. Using Delsys Trigno wireless sensors were an ideal match for this experiment, given their built-in EMG artifact suppression technology and integrated 3D accelerometers. Full article...
