RESUMO
Objective To observe the effect of breathing exercise based on core strength training on nonspecific low back pain (NLBP). Methods From January to June, 2017, 60 patients with NLBP were randomly divided into control group (n=30) and ob-servation group (n=30). The control group accepted core strength training, and the observation group accepted breathing exercise in addition, for four weeks. They were assessed with Visual Analogue Scale (VAS) and Oswes-try Disability Index (ODI) before and after treatment, and their efficiency was compared. Results The scores of VAS decreased in both groups after treatment (t>4.173, P<0.001), and the scores of ODI de-creased in the observation group (t=3.875, P<0.01). The scores of both VAS and ODI were less in the observa-tion group than in the control group (t>2.595, P<0.05). The efficiency was better in the observation group than in the control group (χ2=3.874, P<0.05). Conclusion Breathing exercise based on core strength training can further improve function and relieve pain in patients with NLBP.
