- Comparison of mean static lumbar angle (LA) after dynamic change across 7 dynamic sitting strategies (DSSs), which include Lumbar Prominent Dynamic Sitting (LPDS), Back Reclined Dynamic Sitting (BRDS), Femur Upward Dynamic Sitting (FUDS), Lumbar Prominent with Back Reclined Dynamic Sitting (LBDS), Lumbar Prominent with Femur Upward Dynamic Sitting (LFDS), Back Reclined with Femur Upward Dynamic Sitting (BFDS), and Lumbar Prominent with Back Reclined with Femur Upward Dynamic Sitting (LBFDS). Values are mean ± standard deviation (N = 20). The positive value (+) represents the lumbar lordosis while the negative value (−) represents the lumbar kyphosis
