Abstract

The muscular strain of the lower extremities when walking “normally” and “sideways” was analysed using the simple, simulated U-assembly line in the Laboratory of the Institute for Ergonomics and Human Factors in Darmstadt (IAD). Test subjects executed their assembly operations in different scenarios in two studies. The U-line in the first study consisted of three work stations and five work stations in the second one. Electrical activities (EA) in six leg muscles on each leg (left and right) were measured and analysed by using EMG method. Ten test subjects without experience in assembly work took part in both studies. The results in the first study show that walking “sideways” puts lower extremities under more stress than walking “normally” does. We were able to record higher electrical activities values (especially dynamic EA-shares) in four out of six analysed leg muscles. EMG-results in the second study show that when “walking sideways counter-clockwise”, three muscles on the right leg are under greater stress than the muscles on the left leg.
