Association Trunk Muscle Endurance in extension and BP


Andersen 2006


Time, obtained by Sorensen-Biering’s test

LBP/MBP/NP < 1 month Age at 1st BP Consequences

BP last month

YES, isometric endurance in the trunk muscle was negatively associated with back pain after adjusting for height and sex

Odds ratio: Three upper quartiles Vs lowest quartile

OR = 0.89 (95 % CI, 0.78-1.02)

OR = 0.78 (95 % CI, 0.68-0.89)

OR = 0.71 (95 % CI, 0.62-0.82)




Time, obtained by Sorensen-Biering’s test

CLBP Subgroup within control group with LBP


YES, the endurance in back extensors were less in the CLBP group

Sorensen Median(min:max) (25 s:3 min43)

Control group 2 min31 (32 s:10 min2)

CLBP 1 min45


Perry 2009


Time, obtained by Sorensen-Biering’s test

BP pain (without NP) Ever Month Chronic Diagnosed

BP pain Ever Month Chronic Diagnosed

NO for male Yes, for girls. Increased likehood of diagnosed back pain was associated with reduced back endurance (OR = 2.05; 95 % CI, 1.16-3.60) and greater back endurance (OR = 2.00; 95 % CI, 1.10-3.60)


Johnson 2009


Time, obtained by Sorensen-Biering’s test of static muscular endurance

1-year BP Present BP

1-year BP Present BP

YES Patient without LBP had a significant higher isometric holding time than those with history of previous LBP and those with present LBP.

  1. CS: cross-sectionnal study
  2. RS: retroprospective study
  3. BMS: back muscle strength (in extension)
  4. BP: Back pain
  5. LBP: Low back pain
  6. CLBP: Chronic low back pain
