An EMG technique for measuring spinal loading during asymmetric lifting.


OBJECTIVES To compare two methods of calibrating the erector spinae electromyographic signal against moment generation in order to predict extensor moments during asymmetric lifting tasks, and to compare the predicted moments with those obtained using a linked-segment model. METHODS Eight men lifted loads of 6.7 and 15.7 kg at two speeds, in varying… (More)
