Hip Flexion-Extension: Bland-Altman plots of pose-estimation-based (camera) and inertial measurement unit (IMU)-based (sensor) shank kinematics quantifications of the aquatic hip flexion-extension exercise evaluated in the present study. Flexion and extension phases were quantified independently and pooled in the analysis. Note that the absolute values rather than signed values were used in these analyses. (a) Mean angular velocity of repetition phase. (b) Phase duration. (c) Range of motion of the phase.
