This study investigated the reliability of ultrasound in combination with surface electromyogram (EMG) for evaluating the activity of the abdom-inal muscles in individuals with and without low back pain during the abdominal drawing-in maneuver (ADIM). The study recruited ten indi-viduals with or without low back pain, respectively. While the partici-pants were performing the ADIM, the activities of the transversus ab-dominis (TrA) and the internal oblique (IO) were measured using ultra-sound, while the activities of the external oblique (EO) and the rectus abdominis (RA) were measured using surface EMG. Intra-class cor-relation coefficients (ICC) were used to verify the inter-rater reliability of ultrasound in combination with surface EMG at rest and during the ADIM, and Bland-Altman plots were used to verify intra-rater reliability. The inter-rater reliability for the two groups at rest and during the ADIM was excellent (ICC2,1=0.77-0.95). In the Bland-Altman plots, the mean differences and 95% limits of agreement in the abdominal muscles of the two groups at rest were -0.03~0.03 mm (-0.66 to 0.60 mm) and -0.12~ -0.05 (-0.58 to 0.48% MVIC), respectively. The mean differences and 95% limits of agreement in the abdominal muscles of the two groups during the ADIM were -0.04~0.02 mm (-0.73 to 0.65 mm) and -0.19~0.05% MVIC (-1.24 to 1.34% MVIC), respectively. The ultrasound in combination with surface EMG showed excellent inter-rater and intra-rater reliability at rest and during the ADIM.
