Dear Mel
I know as a South African you will not mind me adding that fast bowlers in
cricket are reputed to have the highest incidence of spondylosis. In an
article, not at hand, but approx five years ago in the JOSPT it was
suggested that the combined actions of extension, sideflexion/rotation were
the shear forces reponsible for the injury to the pars interarticularis in
the lumbar spine. Perhaps suggesting a different predisposing movement from
the flexion activities.
I could personally see this as the compression forces would be immense on
the boney structures, but have little more than the above article and
clinical experience to back it up. The piece also suggests that 6% of adult
males has a spondylolythesis, a bit extreme perhaps. It certainly makes me
be careful of using extension in undiagnosed LBP.
