Conclusions.

In a sample of LBP patients who were treated with gabapentin because they were diagnosed with potential LRP by the BUAS test, all of the study’s prespecified endpoints of MICC in PD and BPI outcome changes were reached. These results may be considered a piece of ex-adiuvantibus evidence for the ability of the BUAS test to detect lumbar-RP. While positive BUAS test implies potential lumbar-RP, the co-presence of positive SLRT, may imply a severer lumbar-RP condition. To generalize findings, more prospective research in different clinical settings and direct clinical measures is needed.
