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 .
Effects of dynamic office chairs on trunk kinematics, trunk extensor EMG and spinal shrinkage
Seated work has been shown to constitute a risk factor for  low-back pain .  This is attributed to the prolonged and monotonous low-level mechanical load imposed by a seated posture . To evaluate the potential health effects with respect to the low back of office chairs with a movable seat and back rest , trunk kinematics , erector spinae EMG , spinal shrinkage and local discomfort were assessed in 10 subjects performing simulated office work .  On three separate occasions subjects performed a 3 h task consisting of word processing , computer-aided design and reading . Three chairs were used , one with a fixed seat and back rest and two dynamic chairs , one with a seat and back rest movable in a fixed ratio with respect to each other , and one with a freely movable seat and back rest .  Spinal shrinkage measurements showed a larger stature gain when working on the two dynamic chairs as compared with working on the chair with fixed seat and back rest . Trunk kinematics and erector spinae EMG were strongly affected by the task performed but not by the chair type . The results imply that dynamic office chairs offer a potential advantage over fixed chairs , but the effects of the task on the indicators of trunk load investigated were more pronounced than the effects of the chair
