Asociación entre dolor y contracción isométrica de la zona neutra lumbar; Hospital Homero Castanier Crespo

Abstract

Low back pain is considered an important public health problem and is associated with high socioeconomic costs, work absenteeism and disability (1). The lumbar spine has vertebral stabilization systems during dynamic tasks (active and control systems); however, people with low back pain show changes in their morphology and motor control that affect their stability. OBJECTIVE: Describe the association between the amount of low back pain and the level of isometric activity of the muscles which keep the stability in the neutral zone through the central stability test of Sahrmann in the patients that receive treatment in the area of physical therapy of the hospital “Homero Castanier Crespo”. METHODS: A correlational and cross-sectional study was carried out with 30 people. The scales used were the Sahrmann Central Stability Test and the Visual Analog Scale (VAS). The results are presented using frequencies, percentages and the Spearman correlation test. RESULTS: Of the sample studied a 73.3% (n=22) of the patients presented stability levels of 0 and 1. The coefficient of correlation was 0.238 which would indicate a week correlation between these variables. Based on a significance level of 0.05. An error probability of 20.5% (ρ > 0.05) was obtained. CONCLUSION: The degree of pain and the level of isometric contraction seem to be unrelated, but it was observed that people with low back pain have low levels of stability associated with changes in motor control
