Functional disability and influencing factors of lumbar disc herniation patients

Abstract

Objective To investigate the functional disability of lumbar disc herniation (LDH) patients and to analyze influencing factors. Methods A total of 260 LDH patients treated in the 2nd Affiliated Hospital of Wenzhou Medical University from November 2015 to April 2016, were selected by convenience sampling method and evaluated by Oswestry low back pain-disability index-Chinese vision (ODI-C) about their functional disability, with the results analyzed by single factor analysis, Pearson correlation and hierarchical regression analysis. Results 216 valid questionnaires were regained, which showed that ODI-C scores of all the 216 LDH patients were (26.00±11.83) points. It was shown in single factor analysis that age, course of disease and surgery influenced the patients' functional disability. It was shown in Pearson correlation analysis that interference of the pain degree or the pain, on the patients' life was positively correlated with the patients ODI-C score, and so was their condition of depression (r=0.765, 0.725, 0.708; P<0.05) . It was shown in regression analysis that, after control of demographic variables, interference of the pain degree or the pain, on the patients' life, and the condition of depression, were independent influencing factors of functional disability of LDH patients, which accounted for 39.7% of the amount of variability. Conclusions Functional disability is common in LDH patients, which can be reduced by relieving their pain and depression.
