Assessing the effect of self-positioning on cognitive executive function

Tidsskriftartikel - 2012


[Open access] Objective: The aim of this pilot study was to explore the effects of self-positioning on cognitive performance in the work environment using a standardized cognitive test battery to evaluate executive function under two conditions.Methods: This randomized controlled cross-over trial involved 17 men (mean age ± SD: 29.8 ± 5.5) all witha science background. The participants were accustomed to working in an open environment and none of whom currently using standing desks. We used a modified version of the CNS Vital Signs (CNSVS) test battery to assess cognitive executive function in two typical work positions - standing and seated. Participants were randomly assigned to a standing or seated position to begin the testing procedure. Upon completion of the first test round they were instructed to rest for 10 min in a dark room with no distractions before commencing the second round of testing positioned in the alternate fashion. The main outcome measure was a CNSVS score in each of the six cognitive executive function domains in the two different work positions.Results: A two-tailed paired t-test showed a significant difference between the standing (mean+/-SD: 94 ± 10)and seated (mean ± SD: 99 ± 9) position (p
