Brief summary

Detailed description

The aim of this trial has been 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: sitting and standing. Methods: This counterbalanced controlled trial involved 17 men (mean age +/-SD: 29.8 +/- 5.5) all with a science background and graduate degrees. 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 (CEF) 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 CEF domains in the two different work positions

Interventions

BEHAVIORALposture: sitting or standing

Intervention: postural position - whether seated or standing. The person carries out a battery of cognitive executive functioning assessments delivered via a laptop and carried out with the laptop keyboard while either seated or standing.
