Abstract:

Objective    To explore  related factors with the effect of epidural block plus SLR exercise for lumbar disc herniation, and further improve the efficacy of treatment. Methods    The data of 270 lumbar disc herniation cases, treated with epidural block plus SLR exercise from January 2005 to January 2009 at the Department of Rehabilitation Qilu Hospital of Shandong University,  were reviewed. Gender, age, incentives, occupation, duration, past medical history, clinical symptoms (JOA score),  protruding type, protruding segment, protruding size, and spinal canal or lateral recess stenosis were observed.  Which treatment efficacy was the dependent variable, while the 12 other factors were the variables. Single factor analysis was performed, and multivariate logistic regression analysis was be done on the significant factors singled out. Results    Univariate analysis showed that duration, place of stenosis (spinal canal or lateral recess), with or without predisposing factors, clinical symptoms (JOA score), protruding type, and protruding segment were significantly related to the prognosis of lumbar disc herniation（P＜0.05）. Multivariate logistic regression analysis further revealed that duration, place of stenosis, and predisposing factors were independent risk factors affecting the efficacy. Conclusion    Long duration, spinal canal and/or lateral recess stenosis, and no predisposing factors are independent risk factors which can affect the results of epidural block plus SLR exercise for lumbar disc herniation. These factors should be considered during the treatment.
