Cognitive and skill performance of individuals at sitting versus standing workstations: a quasi-experimental study

Abstract

Objectives. This study aimed to assess cognitive and skill performance at sitting and standing workstations among students from Shiraz University of Medical Sciences. Methods. Forty students (20 females and 20 males) participated in this quasi-experimental study. Tests were performed among randomly selected participants over two consecutive days: day 1, the Beck depression inventory and Beck anxiety inventory were used to assess the severity of depression and anxiety in the study participants, respectively, and Raven’s general intelligence test was used to measure intelligence quotient; day 2, five performance assessment tests (cognitive performance assessment tests ‘n-back’, ‘Stroop’ and ‘advanced reaction time’; skill performance assessment tests ‘two-arm coordination’ and ‘Purdue pegboard’) were randomly selected and presented to individuals at each workstation (sitting and standing workstations). At the end of each sitting and standing position, the comfort of the workstation was measured using a visual analog scale. Results. No statistically significant difference was shown between sitting and standing positions in terms of ‘n-back’, ‘Stroop’, ‘advanced reaction time’, ‘two-arm coordination’ and ‘Purdue pegboard’. Participants were more comfortable in sitting positions and more easily distracted in standing positions. Conclusions. Sitting and standing positions had no significant effects on participants’ cognitive and skill performance.
