The relationship between objective and subjective evaluation criteria in lumbar spinal stenosis
Abstract
Methods: Thirty patients (25 females, 5 males; mean age 62±9 years; range 41-78 years) were prospectively studied. All were diagnosed as having LSS by clinical and radiological evaluations. Pain was assessed by a visual analog scale. The patients were evaluated by two-staged treadmill exercise tolerance (TET) test, SF-36 health status survey, and Oswestry Disability Index (ODI). The relationships between the TET test, which is an objective functional assessment, and patient-based assessments (SF-36 and ODI), pain and age were investigated.
Results : There were significant differences between the functional grades of the patients at the speed of 1.9 km/hour with respect to ODI scores, the physical component scale of SF-36, age, and the preferred speed of the patients (p<0.05). These differences emerged from the fourth functional stage (p<0.01). Oswestry disability scores and the physical componentscores of SF-36 worsened in parallel with the stages of the TET test. The preferred speed of the patients at the TET test was positively correlated with the physical component scores of SF-36 and negatively correlated with Oswestry disability scores (p<0.05). There was a negative correlation between the physical component scores of SF-36 and Oswestry disability scores (p<0.05).
Conclusion: The TET test used to determine the functional capacity seems to be correlated well with subjective patientbased assessments. This objective tool, when combined with subjective assessments, may be helpful in the evaluation and treatment of patients with LSS.
