A revised model of skin marker placement with the two-dimensional (2D) PEAK Motus system was used to investigate the effect of aging on sagittal range of spinal motion. Twenty-four healthy young adults and twenty-two healthy older adults were videotaped while performing the movements of flexion and extension in each spinal region--cervical, thoracic and lumbar spine. Alternative movement tests that may allow a greater range of motion (ROM) for thoracic extension and lumbar flexion were also investigated. Older adults demonstrated significantly decreased flexion/extension ranges in the cervical, thoracic and lumbar spine. The movement of cat-stretch in the all-fours position allowed greater thoracic extension, and the movement of toe-touch in standing permitted greater lumbar flexion. This study provides reference data for sagittal ranges of spinal motion in healthy young and older adults as measured by a 2D imaged-based system. The sagittal model of skin marker placement used in this study can have a broader application for ROM measurement in the clinical setting using a digital camera and freely downloadable software.
采用二维（2D）PEAK Motus系统的皮肤标记放置修正模型，研究衰老对脊柱矢状面运动范围的影响。对24名健康年轻成年人和22名健康老年人在每个脊柱区域（颈椎、胸椎和腰椎）进行屈伸运动时进行录像。还研究了可能允许更大胸椎伸展和腰椎屈曲运动范围（ROM）的替代运动测试。老年人在颈椎、胸椎和腰椎的屈伸范围明显减小。四肢着地的猫伸展动作可实现更大的胸椎伸展，站立时的触趾动作可实现更大的腰椎屈曲。本研究提供了通过基于二维成像系统测量的健康年轻和老年人脊柱矢状面运动范围的参考数据。本研究中使用的皮肤标记放置矢状面模型可在临床环境中使用数码相机和免费下载软件进行ROM测量时得到更广泛的应用。
