Perching (06-04-19)

Noguchi and colleagues studied the experience of “perching.”  As the researchers explain, “Potential alternatives for conventional sitting and standing postures are hybrid sit-stand postures (i.e. perching). . . . participants completed 19 1-min static trials, from sitting (90°) to standing (180°), sequentially in 5° trunk–thigh angle increments. The perching phase was determined to be 145–175° for males and 160–175° for females. . . . Chair designs aimed at reducing the lower limb demands within 115–170° trunk–thigh angle may improve the feasibility of sustaining the perched posture. . . . Perching can improve lumbar posture at a cost of increased lower limb demands, suggesting potential avenues for chair design improvement.”
