Bland-Altman plots demonstrating the difference for joint angles when using IMU derived kinematics and standard lab-based motion capture system for (a) neck flexion/extension, (b) trunk flexion/extension, (c) shoulder elevation, and (d) elbow flexion. The dashed line represents the mean, while the solid lines represent the 95% limits of agreement (± 1.96 SD). ICC(A,1) values and linear regression equations are also presented.
