The results suggest there is currently no evidence to support the use of dynamic sitting as a st and -alone approach in the management of LBP .
Overall , the evidence suggests that dynamic sitting approaches are not effective as a st and -alone management approach for LBP
Dynamic sitting has been proposed to reduce  low back pain ( LBP ) and /or low back discomfort ( LBD ) while sitting .
This is supported by studies suggesting that subjects with LBP assume more static , sustained postures while sitting .
This systematic review investigated the effect of dynamic sitting on LBP among subjects with LBP and the development of LBD among pain-free subjects .
Practitioner Summary : This systematic review investigated the effect of dynamic sitting on LBP or LBD .
Passive rotary dynamic sitting at the workplace by office-workers with lumbar pain: a randomized multicenter study.
BACKGROUND CONTEXT It is generally recognized that long periods of sitting can either cause or aggravate lumbar pain . A new , ergonomically design ed chair has a fixed backrest and a motor-driven seat with a horizontal rotary movement in alternating left-right cycles . PURPOSE The objective of this study is to prove superiority of the new technique of passive rotary dynamic sitting for subjects working in a sedentary occupation and suffering from lumbar pain . STUDY DESIGN / SETTING A r and omized , double-blind , multicenter , two-armed study was performed using a parallel group design . PATIENT SAMPLE 280 persons suffering from lumbar pain were matched pairwise and r and omized en bloc . OUTCOME MEASURES The first and second primary endpoints target criteria were the vali date d German version of the Oswestry Disability Index ( ODI ) and the number of days of absence from work ( DA ) attributable to lumbar pain , each based on a blinded 2-year follow-up observation after r and omization of the subjects . METHODS After inclusion in the study anonymization , the prob and s were r and omized to receive either an office chair with a motor-driven seat performing a horizontal rotary movement or a chair of the same design without the rotary seat movement . Before delivery of the chairs , 23 prob and s ( 8.2 % ) withdrew their consent to inclusion in the study without stating reasons . From 12 of the remaining matching partners , 23 new pairs were created at r and om , and the study commenced with 124 pairs . RESULTS A further 27 prob and s ( 9.6 % ) were lost to follow-up during the period up to the final consultation . This made it possible to observe the primary endpoint in 82.5 % of the prob and s. The median ODI in both groups was 53 ( 95 % confidence interval for median difference:-1.5 to 0.5 ; p=.59 ) . Median DA in both groups was 0 ( 95 % confidence interval for median difference:-infinity-+infinity ; p=1.00 ) . CONCLUSIONS Under the test conditions used in this study , passive rotary dynamic sitting was not superior to sitting in a high- quality , ergonomically design ed chair not equipped with a micro-rotation function in patients suffering from lumbar pain
