Purpose of the study

● To investigate the relative and absolute intertester reliability of the fingertip-to-floor distance (FFD) test and the modified Schober (mSchober) test.

● This was done in a heterogeneous sample of patients (n=98) with specific and non-specific LBP, pelvic girdle pain and patients without pain.

● The secondary purpose was to investigate the correlation between the two tests as a measure of concurrent validity.

Results

● Excellent relative intertester reliabilitet, ICC3,1 (95% CI) was 0.93 (0.90-0.95) and 0.77 (0.67-0.84) for the FFD test and the mSchober test respectively.

● Absolute reliability, measured by smallest detectable change (SDC), was 9.8 cm and 1.8 cm for the FFD test and the mSchober test, respectively.

● A medium negative correlation was found between the two tests (r=-0.47, p<0.001).

Conclusion

● Changes of 9.8 and 1.8 cm, for the FFD test and the mSchober respectively, are needed to detect a true change. ● The results indicates that both tests should be used together in the clinics;

● To evaluate the patient’s lumbar flexion ROM (mSchober test)

● To evaluate the functional ability to bend forward (FFD test)
