[The effect of palliative neural therapy on the improvement of chronic pain].

Background And Purpose: To assess the extent to which pain therapy can improve chronic pain in a heterogeneous group of patients, its impact on their quality of life and the correlation of the changes with their age and the underlying disease. The investigation has its actuality by its impact on public health.

Methods: a prospective, non-randomized, interventional, clinical cohort study was conducted under real-life conditions in a general pain clinic, which lasted for 6 months. Changes in pain intensity (VAS) and related quality of life changes (SF-36 HRQoL) were measured using validated internationally accepted questionnaires. The questionnaires were filled out by all patients on their own, so they provided information of self-esteem on their own. All patient post-treatment results were compared to pre-treatment results. The general quality of life changes found in our patients were compared to the representative norms of healthy population in Hungary. Subjects - patients participated voluntarily at their own decision in the survey. The underlying disease of chronic pain, age and gender of the patients did not limit the inclusion into the study.

Results: Data of 231 patients were evaluated. After pain therapy, the decrease in intensity of pain was confirmed by VAS at p=0.002. This was linked to a quality of life change that has been shown to be p=0.003 for men, with p=0.002 in women with SF-36 HRQoL. Based on the correlation coefficients, the changes in quality of life improved regardless of the age of the patients and the nature of the underlying conditions causing the pain.

Conclusion: Although analgesia is basicly a symptomatic therapy, our findings suggest that the reduction of pain improves the quality of life of patients independently from their, and the curability of the underlying and accompanying diseases.
