Research Design Connection: Perching
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.” Mamiko Noguchi, Michel Glinka, Graham Mayberry, Kimihiro Noguchi, and Jack Callaghan. 2019. “Are Hybrid Sit-Stand Postures a Good Compromise Between Sitting and Standing.” Ergonomics, vol. 62, no. 6, pp. 811-822, https://doi.org/10.1080/00140139.2019.1577496 Sally Augustin, PhD, a cognitive scientist, is the editor of Research Design Connections (www.researchdesignconnections.com), a monthly subscription newsletter and free daily blog, …
