Techniques for active lumbar stabilisation for spinal protection: A pilot study

C Richardson et al. Aust J Physiother. 1992.

Abstract

Active protection of the lumbar spine is important in prevention of back strain during exercise. This EMG study investigated three common techniques used for lumbar stabilisation : posterior pelvic tilt, lower abdominal hollowing with lumbar spine flattening and abdominal bracing. The aim was to determine which method encouraged the best stability pattern. Muscle activity was measured in obliquus abdominis, upper and lower rectus abdominis and the lumbar erector spinae. Standardisation of muscle activity against that during maximally resisted trunk rotation (already shown to illustrate an appropriate stability pattern) allowed comparisons between exercise techniques in relation to their stabilisation pattern. Results indicated that posterior pelvic tilt demonstrated the least desirable stability pattern. Both abdominal hollowing and bracing provided a more suitable pattern.
