The Effects of armrests and high seat heights on lower-limb joint load and muscular activity during sitting and rising / Ulf P. Arborelius, Per Wretenberg and Fredrik Lindberg

Sumario: The loading moment of force on the hip, knee, and ankle joints of nine healthy men rising from four different types of stools were compared, together with the levels of myoelectrical activity (EMG) in four leg muscles. Two types of stool had higher seats than a normal chair. The other two were of ordinary seat heigh, but one also had armrests. It was concluded that stand stools are good alternatives for workers who change frequently between siting and standing work
