Outline of Final Research Achievements

The assessment of the LROM using x-ray is still one of the most precise methods, despite the radiation exposure. To avoid this, alternative methods, such as the VICON system and electrogoniometer, have been widely used. No study has reported LROM measurements using a VICON system. The VICON system and electrogoniometer measured LROM and lumbar motion in 7 healthy males during 7 days. The mean maximum LROM values using the VICON system/electrogoniometer were 42°/52° for flexion, 17°/24° for extension, 16°/16° for lateral bending, and 8°/2° for axial rotation. Between VICON system and the electrogoniometer, Bland-Altman plots revealed no discrepancies in LROM values except for flexion. LROM measurements with VICON system showed excellent reliability for flexion and extension and fair-to-good reliability for other motions. VICON system with our novel marker set allows practical and reliable longitudinal assessment of dynamic LROM.
