Adequate reference procedures for obtaining the zero-angle position are important precise and accurate posture measurements, but few studies have systematically investigated these. A limited number of previous suggest differences in accuracy between procedures, with some causing an underestimation true arm elevation angle when sensors taped to skin. The reliability commonly used measurement trunk is also not well explored, alternative may improve precision. Based on this identified gap, study evaluated test–retest N-position (I-pose), i.e., standard procedure recording postures, compared it two new procedures. Additionally, measuring angles was one procedure. total 40 participants (22 women 18 men) aged 26–70 years performed a laboratory setting. Postures were recorded using smart workwear system equipped inertial units (IMUs) embedded pockets within workwear. For posture, showed slight lack reliability, while demonstrated better reliability. N-position, which does include lateral inclination, resulted substantial approximately 15°, novel finding. In contrast, involving inclination closely matched targeted reference, difference less than 2°. This underscores importance selecting appropriate ensure measurements.
