Table 5 The association between back muscle endurance in extension and back pain in people younger than 19 years as reported in four studies

From: Is back pain during childhood or adolescence associated with muscle strength, muscle endurance or aerobic capacity: three systematic literature reviews with one meta-analysis

Ref numb. Name of first author/aawyear Design of study Independent variable Dependent variables listed in method Dependent variables reported in result section Association Trunk Muscle Endurance in extension and BP
[28] Andersen 2006 CS 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)
[29] Bernard RS Time, obtained by Sorensen-Biering’s test CLBP Subgroup within control group with LBP CLBP 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
[30] Perry 2009 CS 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)
[31] Johnson 2009 CS 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
