The manipulative treatment with stabilizing exercises was more effective in reducing pain intensity and disability than the physician consultation alone. The present study showed that short, specific treatment programs with proper patient information may alter the course of chronic low back pain.

There is limited evidence that radiofrequency denervation offers short-term relief for chronic neck pain of zygapophysial joint origin and for chronic cervicobrachial pain, and conflicting evidence for its effectiveness for lumbar zygapophysial joint pain. There is limited evidence suggesting that intradiscal radiofrequency may not be effective in relieving discogenic low back pain. Further high-quality randomized controlled trials are needed, with larger patient samples and data on long-term effects, for which current evidence is inconclusive.

Physician consultation alone was more cost-effective for both health care use and work absenteeism, and led to equal improvement in disability and health-related quality of life. It seems obvious that encouraging information and advice are major elements for the treatment of patients with cLBP.

A significant association existed between heart rate variability and perceived physical impairment, but not between heart rate variability and pain. Proportionally reduced high-frequency activity was found to reflect decreased parasympathetic activity or increased sympathetic activity. This resulted in sympathetic dominance among the patients with higher subjective disability. The possible clinical implications of this observation are discussed.
