Analysis of pain symptoms, flexibility and hydroxyproline concentration in individuals with low back pain submitted to Global Postural Re-education and stretching

To evaluate pain, flexibility and hydroxyproline (HP) urinary levels in patients with nonspecific low back pain submitted to Global Postural Re-education (GPR) and stretching. 39 individuals who reported low back pain were randomly assigned to a group submitted to GPR (GPRG) or stretching exercises (SG) for 8 weeks. Pain and flexibility were assessed using the Borg CR10 scale and goniometry, respectively. The GPR group showed a significant reduction in the HP levels and significant improvements in flexibility after the intervention when compared with SG. Both groups presented a significant reduction in HP and pain after the intervention. Both interventions were effective in the treatment of low back pain. However, the GPR method presented better responses than stretching.
