physiobase,

couldn't agree more with you about the poor statistical base of some studies. I myself have no background in statistics, and was surprised at how shallow a level we studied it during our BSc. course. The inclusion of statisticians is essential at the planning stage to ensure that sufficient statistical power for a study is attained as well as the validity of susequent data analysis.

Getting back to core stability, does anyone know of any studies investigating the intertransversarii and rotatores? I have read in one McGill article that these small muscles are richly innervated with muscle spindles (up to 8x no. in multifidus). Their role is suggested to be positional sensors more than movement initiators/synergists.This begs the question are they somehow implicated in the dyskinesia seen in LBP subjects? could these muscles become hypo/hyperactive? Just a thought. Look forward to your replies

Yours
