Any further tensing of the abdominal muscle may lead to additional spinal compression.

“Since the spinal compression in lifting approach the margins of safety of the spine, these seemingly small differences are not irrelevant”

Biggemann et al., 1988

Bending and lifting is associated with low abdominal muscle activity, which contributes to further spinal compression

de Looze et al., 1999

In patients with CLBP lifting is associated with higher levels of trunk co-contraction and spinal loading

Marras et al., 2005; Cholewicki et al., 1997

Psychological stress during lifting resulted in a dramatic increase in spinal compression associated with increases in trunk muscle co-contraction and less controlled movements Davis et al., 2002
