PURPOSE: This study determined whether the combined application of sling exercises (SE) with targeted vibration and oscillations using a device called the Vibraoscillator (VO) is effective in reducing pain intensity, increasing range of motion (ROM), and enhancing back-related functions in patients with chronic nonspecific low back pain (CNLBP). MATERIALS AND METHODS: Thirty-six participants were randomized into experimental (SE plus VO) and control (SE) groups. Both groups received the intervention twice a week for 4 weeks. The pain was assessed using the Numerical Rating Scale (NRS), ROM was measured using the Modified-Modified Schober's Test (MMST), and the level of disability was evaluated using the Oswestry Disability Scale (ODI). In addition, the global perceived effect (GPE) was determined. RESULTS: NRS and ODI scores significantly improved after the intervention in the experimental group. Only lumbar spine extension improved significantly in the case of ROM. The GPE satisfaction rate was 14.5% higher in the experimental group than in the control group. CONCLUSION: Based on the findings obtained in this study, the combined use of VO and SE in patients with CNLBP was effective in reducing pain, improving ROM, and reducing physical disability in comparison with the treatment of only SE.
