TI  - Trunk muscular strength in pre-pubertal children with and without back pain.
PG  - 97-103
AB  - OBJECTIVE: While in adulthood there is no proven relationship between back pain 
      and trunk muscle strength, in pre-pubertal subjects this topic has been poorly 
      studied. The aim of the study was to evaluate isometric and isokinetic trunk 
      muscle strength in children with or without previous back pain. METHODS: The 
      recent occurrence of back pain (last 6 months) among 144 children (77 males, 67 
      females, age 11.9 +/- 0.3 years) was assessed using a questionnaire. Extensor and 
      flexor trunk muscle strength was measured through isometric and isokinetic (60, 
      90, 120 degrees/s) tests. Peak torque (PT), PT angle, PT flexor/PT extensor ratio 
      and intra-session coefficient of variation (COV) were determined. RESULTS: Flexor 
      and extensor muscle PT, but not PT angle, were significantly higher in males than 
      in females, irrespective of back pain occurrence. PT flexor/PT extensor ratio at 
      90 degrees angular velocities increased significantly only in males with back 
      pain, compared with males without back pain. The COV trend was similar for flexor 
      and extensor muscles. CONCLUSIONS: Isometric and isokinetic trunk muscle strength 
      probably play a minor role in back pain occurrence in children. The isokinetic 
      testing velocity may be important in determining trunk strength differences 
      between children with and without back pain.
