Abstract

Background: low back pain affects to 84% of population at some point in their lives, it represents the second cause of medical consultation at orthopedics, third of surgical procedures and fifth of hospital admission; converting it into the main musculoskeletal condition responsible of disability, mobility restriction and alteration in quality of life. General Objective: determinate the relationship between pain, disability and quality of life in patients with non-specific low back pain in the Physiotherapy Area of the Vicente Corral Moscoso hospital during the period 2017-2018. Methodology: a descriptive, prospective, cross-sectional study was performed with 50 patients with non-specific low back pain. The valuation instruments used were the Visual Analogue Scale (VAS), the Oswestry questionnaire (ODI) and the Short Form 36 questionnaire. Results are presented in frequency tables, percentages, central tendency measures, dispersion measures and the Spearman’s correlation coefficient. Results: in our study population, the average age was 44 years old, 72% corresponded to female sex and 28% to male. Of all the respondents, 46% presented non-specific low back pain of moderate intensity and 36% chronic non-specific low back pain. The mean value for EVA was 56mm, the highest frequency for ODI belonged to moderate functional limitation (36%), the average for the physical component of the SF-36 was 42.16 and within this the physical role with a mean value of 26 turned out to be the most affected. Spearman’s correlation coefficient obtained was 0.596 which suggest a moderate to strong relationship between pain intensity and the disability index based on a significance level of 0.002 (p<0.05). Conclusion: pain intensity and the disability index correlate positively and the quality of life is negatively influenced by these variables
