      <subfield code="a">Low-back pain arising from repetitive lifting of objects out of deep containers is a significant problem in many industries and results in a great deal of time lost from work. This study measured electromyographic (EMG) activity of the lumbar paraspinal muscles, vertical acceleration of three different loads, and the reaction force of the supporting upper extremity to compare the assisted one-hand lift techniques. Results of this study seem to indicate that, under certain circumstances, the one-hand lift is a less stressful method of lifting than the two-hand stoop method</subfield>
