Biomechanical Evaluation of a Lift Assist Device while Using a Light Weight Jackhammer
There are currently relatively few interventions designed to decrease the risk of injury while operating a jackhammer. One intervention that is aimed at reducing the risks of overexertion and repetitive lifting injury is the lift assist attachment. However, research on the effectiveness of this device is non-existent. This study investigated the effectiveness of the lift assist device through the muscle activity and grip pressure variations while using a light weight jackhammer. The lift assist reduced grip pressure by 31%, along with the left and right Bicep Brachii muscle activity by 49% and 45% respectively. These results show that the effort required to lift the jackhammer is being reduced through the use of the lift assist. With less effort required by the operator, the risk of an overexertion or repetitive lifting injury is decreased.
