StEP scores for the distinction between radicular and axial LBP.

Scores reflect the regression coefficients of grouped StEP items; for example, a score of 2 was given when the response to pinprick was decreased or when pinprick evoked a hyperalgesic response. StEP items with a regression coefficient of 0 (zero) are not listed. A higher score is indicative of radicular LBP (see Table 3).评分反映了分组StEP条目（StEP items）的回归系数；例如，当针刺刺激反应减弱，或针刺引发痛觉过敏反应时，评分为2。回归系数为0的StEP条目未被列入。评分越高，提示神经根性腰痛（radicular LBP）的可能性越大，详见表3。
