OBJECTIVE: The purpose of this study was to assess examiners' intrarater and interrater reliability to use a pressure biofeedback unit (PBU) during 6 lower limb movement tests based on Movement System Impairment classification model for low back pain (LBP) in people with nonspecific LBP. METHODS: Thirty subjects (13 men and 17 women) with chronic nonspecific LPB were assessed during 6 lower limb movement tests based on Movement System Impairment classification using a PBU. Each test was performed twice by 2 assessors with a 48-hour interval between test sessions. Reliability indices of PBU measures (intraclass correlation coefficient [ICC]) were calculated. RESULTS: Intrarater reliability for hip and knee movement tests was good to excellent (ICC(3,3), 0-.60-0.95). Interrater reliability for hip and knee movement tests was fair to excellent (ICC(2,3), 0.40-0.86). Standard error of the measurement and smallest detectable change for the movement tests ranged from 1.4 to 11.3 mm Hg and from 3.9 to 31.3 mm Hg, respectively. CONCLUSIONS: The results of this study indicate that trained examiners can reliably perform PBU measures for patients with chronic LBP.
