… arm of 4.1 cm under the conditions of trunk flexion and load asymmetry. This compares
well … or the temporal parameters that would describe the duty cycle. Thus, there is a need to …

… a trunk flexion of ~75% of their maximal range of trunk flexion. In … Trunk motion was obtained
by calculating the trunk flexion … From the trunk motion, three variables were extracted. 1) The …

… trunk neuromuscular responses to unexpected trunk perturbation. More specifically, the
targeted neuromuscular responses were trunk muscle activity reflex and trunk … related to trunk …

… The findings of this study provide direct evidence of the biomechanical effects of LB use
during trunk flexion/extension. Wearing a LB significantly reduced lumbar ROM while pelvis …
