back bonz -> Biering-Sorensen test (February 6, 2006 1:53:00 PM)

What is considered a "good" time or bad time to hold? An abstract from spine stated 17.5 for asymptomatic individuals and 11.6 for those with non specific back pain. But I noticed that in the cpr for the effectiveness of lumbar stab., the hold time is up to 5 minutes. What do you say?

The original research (from the 80's) found that those who could hold for greater than 1 minute had a far lower (5x?) likelihood of future injury than those that could not. Stuart McGill also uses ratios of trunk flexor, extensor, and lateral endurance - the exact numbers are in his two texts.

i seem to recall reading that 80 seconds was the normal hold time for a "healthy" back. but i can't seem to locate that article so don't quote me.

3-5 min. (Maximum holding time, Moffroid, 1993) -> Re: Biering-Sorensen test (February 7, 2006 7:33:00 AM)

As noted by tamil, I also use the 3 minute rule minimum, especially with athletes.

McGill has posted in his book the data from a study: McGill SM, Childs A, Liebenson C. Endurance times for stabilization exercises: Clinical targets for testing and training from a normal database. Arch Phys Med Rehab. 80: 941-944. 1999.

I find that there is more to low back pain then muscle endurance, but for people getting a graded-exercise or general core endurance program (which we can all agree has strong CBT overtones), the targets are worthwhile. However, note the wide variance in scores from 1SD above and below the mean. Such a large variance means these are "very" general targets only.
