Description of intervention(s) / exposure
BEHAVIORAL - Skilled motor training
BEHAVIORAL - Walking exercise

Experimental: 1 -

Active comparator: 2 -


BEHAVIORAL: Skilled motor training
This involves training subjects to independently and cognitively activate the deep abdominal muscles, transversus abdominis, with minimal or no activity in other trunk muscles. The contraction is held for 10 seconds and subjects complete three blocks of ten contractions, twice per day for two weeks. This training protocol is commonly used clinically for people with chronic back pain.

BEHAVIORAL: Walking exercise
The control intervention involves walking exercises for ten minutes, twice per day. Subjects are advised to walk at their own pace with no instructions on activation of specific trunk muscles. The exercise is performed over two weeks.
