Conclusion : sit-st and workstations may reduce low back pain  among workers .
Practitioner Summary : In a sedentary population , changing posture may reduce the chance of developing low back pain .
Abstract Background : Sit-st and workstations are proposed solutions to reduce sedentary time at work .
Numerous companies are using them to mitigate health concerns such as musculoskeletal discomfort .
Objective : To review the literature on sit-st and workstations and low back discomfort .
Breaking up workplace sitting time with intermittent standing bouts improves fatigue and musculoskeletal discomfort in overweight/obese office workers
Objectives To examine whether the introduction of intermittent st and ing bouts during the workday using a height-adjustable workstation can improve subjective levels of fatigue , musculoskeletal discomfort and work productivity relative to seated work . Methods Overweight/obese office workers ( n=23 ; age 48.2±7.9 years , body mass index 29.6±4 kg/m2 ) undertook two , 5-day experimental conditions in an equal , r and omised ( 1:1 ) order . In a simulated office environment , participants performed their usual occupational tasks for 8 h/day in a : seated work posture ( SIT condition ) ; or interchanging between a st and ing and seated work posture every 30 min using an electric , height-adjustable workstation ( ST AND -SIT condition ) . Self-administered question naires measuring fatigue , musculoskeletal discomfort and work productivity were performed on day 5 of each experimental condition . Results Participants ’ total fatigue score was significantly higher during the SIT condition ( mean 67.8 ( 95 % CI 58.8 to 76.7 ) ) compared with the ST AND -SIT condition ( 52.7 ( 43.8 to 61.5 ) ; p<0.001 ) . Lower back musculoskeletal discomfort was significantly reduced during the ST AND -SIT condition compared with the SIT condition ( 31.8 % reduction ; p=0.03 ) . Despite concentration/focus being significantly higher during the SIT condition ( p=0.006 ) , there was a trend towards improved overall work productivity in favour of the ST AND -SIT condition ( p=0.053 ) . Conclusions Transitioning from a seated to a st and ing work posture every 30 min across the workday , relative to seated work , led to a significant reduction in fatigue levels and lower back discomfort in overweight/obese office workers , while maintaining work productivity . Future investigations should be directed at underst and ing whether sustained use of height-adjustable workstations promote concentration and productivity at work .
