Table 2. Segment angle ROM mean and standard deviation.
ROM data (mean ± SD) for motion capture (mocap) and inertial sensors (IMU) for 11 participants (five for cervical flexion/extension). Segment angles are reported for all spinal segments (S1, L1, T6, T1 and SK). The movements from left to right were flexion, extension, lateral flexion, cervical rotation, and cervical flexion/extension.
