Erratum to: prognostic implications of the Quebec Task Force classification of back-related leg pain: an analysis of longitudinal routine clinical data

Excerpt

In the publication entitled ‘Prognostic implications of the Quebec Task Force classification of back-related leg pain: an analysis of longitudinal routine clinical data’ [1] we described the characteristics of low back pain (LBP) patients classified according to the Quebec Classification for spinal pain [2]. The objectives of the study were to investigate whether subgroups consisting of (a) patients with Local LBP only, (b) LBP and leg pain above the knee, (c) LBP and leg pain below the knee, and (d) LBP with leg pain and neurological signs had different prognoses, and to determine if this was explained by measured baseline factors. The included cohort was from a secondary outpatient department. Routine clinical data were collected in an electronic database at the first visit and follow-ups were performed after 3- and 12-months. The study concluded that subgrouping of LBP patients, based on pain location and neurological signs, was associated with activity limitation and sick leave, but not with global perceived effect. Both the presence of neurological signs and having leg pain did have prognostic implications, but whether the reported leg pain was located above or below the knee did not. …
