ABSTRACT

Background: Sciatica Bothersomeness Index and Sciatica Frequency Index are used as the outcome measures for evaluation of bothersomeness and frequency of radiating symptoms in patients with low back pain with radiculopathy. So far, validated Gujarati versions of SBI and SFI have not been reported.
Aim: To validate the Gujarati versions of SBI and SFI.
Study Design: Cross-sectional study
Materials and Methods: SBI and SFI were translated into Gujarati language using forward and back translation method. Face and content validity were examined by group consensus method by an expert committee which consisted of the authors, orthopaedic surgeon, general practitioner and physiotherapists experienced in the field of musculoskeletal rehabilitation. Concurrent validity was examined by correlating SBI and SFI with Maine Seattle Back questionnaire and subscales of SF-36 on 56 patients with lumbosacral radiculopathy aged 18 to 60 years. Test retest reliability was examined by collecting data on initial visit and after 48 hours.
Results: The items were accepted with >80% consensus. Concurrent validity measured by Spearman’s correlation coefficient indicated that SBI and SFI had strong to moderate correlation with MSBQ, VAS for leg pain and most subscales of SF 36 and weak correlation with vitality subscale and VAS for back pain. SBI and SFI had high internal consistency measured by Cronbach’s alpha (alpha=0.94 and 0.89). Test retest reliability was measured by intraclass correlation coefficient which revealed high correlation (ICC=0.84 and 0.78).
Conclusion: Gujarati versions of Sciatica bothersomeness index and sciatica frequency Index are reliable and valid measures and can be used for clinical and research purposes.

Key words: SBI, SFI, Gujarati, radiculopathy, reliability, validity.
