Evaluación de la resistencia de la musculatura flexora y extensora de tronco, y su influencia en la discapacidad y dolor lumbar crónico. Hospital Vicente Corral Moscoso. Cuenca, 2019

Abstract

Background: It is estimated that 9.4% of the population suffers from low back pain, which makes it the first cause of consultation, becoming a public health problem due to work absenteeism, disability and high socioeconomic expenses caused (1) . Trunk instability, muscular endurance and motor control predispose to low back pain (2). General Objective: To evaluate the resistance of the flexor and extensor muscles of the trunk and its influence on the degree of disability and chronic low back pain in patients who attend the Physiotherapy area of the "Vicente Corral Moscoso" Hospital. Cuenca, 2019. Methodology: A prospective descriptive cross-sectional study was conducted in 52 patients with chronic low back pain. The implements used were the Biering Sorensen Test, Flexor Resistance Test, the Roland Morris questionnaire (RMQ) and the Visual Analog Scale (EVA). The results are presented in frequency tables, percentages, central tendency measures, dispersion measures. Results: 94.23% of the population presented a lower than average flexural resistance and 98.08% a lower than average extensor resistance. The moderate degree of disability of Ronald Morris was the most frequent corresponding to 53.85% of the population. Pain intensity obtained an average VAS of 6.60 cm ± 1.88 cm for both genders, and other variables of interest were studied. Conclusion: The patients who presented a decrease in the resistance of the trunk muscles presented a moderate level of disability and pain intensity
