Summary

Introduction:
The Oswestry questionnaire (The Oswestry Disability Index, ODI) evaluates the impact low back pain has on activities of daily living through low back pain, quantifies patients’ subjective complaints and measures the level of disability. Even though multiple versions of the ODI are available, the authors now recommend version 2.1a that has also recently became available in the Czech language. The aim of this study was to emphasise that the new Czech version of ODI is available and to evaluate its correlation with the former Czech version (ODI 1.0) as well as to assess application of the ODI in patients with LSS.

Methods:
Both versions of the ODI (1.0 and 2.1a) were used for evaluation of 69 patients with lumbar spinal stenosis (LSS group) and 63 age and gender matched healthy volunteers (control group). The existence of any differences between both versions was evaluated in general and also with respect to age and gender. The results of the ODI 2.1a were analysed in detail in both groups.

Results:
Median ODI was 40% in LSS group and 0% in controls. No statistically significant differences were found between the two ODI versions neither in the cohort of LSS patients, nor in healthy controls within any of the age subgroups. Correlation analysis proved a high degree of correlation between both versions (r >0.98). Our findings thus proved that both versions of the ODI questionnaire are fully compatible and mutually interchangeable. The results of the ODI were significantly different between the LSS and control groups.

Conclusion :
The new Czech version of the ODI (2.1a) is fully interchangeable with the former version and should now be used to ensure consistency. We proved usefulness of the ODI in evaluating LSS patients.
