Stretching in nonspecific chronic low back pain: a strategy of the GDS method

Abstract

The purpose of this study was to assess the effectiveness of stretching exercises of the Muscle and Joint Chains Godelieve Denys-Struyf (GDS) method in pain reduction, functional disability, increase global flexibility, and ability of the transversus abdominis muscle (TrA) contraction in individuals with nonspecific chronic low back pain. Fifty-five patients, from 18 to 60 years-old, participated in this study divided into two groups: the Stretching Group (n=30) underwent stretching exercises twice a week; the Control Group (n=25) was subjected only to evaluation. Pain was assessed by a visual analogue scale, functional disability by the Oswestry Questionnaire, global flexibility by third finger to the ground test and the ability of TrA contraction by a pressure biofeedback unit. Three evaluations were performed, starting after 8 and 16 weeks from the beginning. Significance level was α<0.05. Results show that the Stretching Group presented a decrease in pain, functional disability, and increased global flexibility (p<0.001) after 8 and 16 weeks (p<0.05). No improvement in the ability of TrA muscle contraction was demonstrated (p=0.13). The sequence of stretching exercises used in the GDS method is effective in reducing pain, functional disability, and improving global flexibility in patients with nonspecific chronic low back pain.
