Establishing normative values and understanding how proprioception varies among body parts is crucial. However, the variability across individuals, especially adolescents, makes it difficult to establish norms. This prevents further investigation into classifying patients with abnormal proprioception. Therefore, the primary objective was to address the knowledge gap using three-dimensional motion analysis to capture position sense in adolescents and young adults. The secondary objective was to evaluate the relationship between position sense and age, as well as the interrelationships of position senses across various anatomical sites. Healthy participants aged 10 to 25 years were included. Six position sense tests were implemented on the trunk, neck, elbow, and knee. Data were captured using a three-dimensional motion capture system. The proprioceptive measure was the absolute repositioning error (the difference between the destinated starting position and the corresponding self-reproduced ending position) of each test. A total of 103 participants were recruited. We found that only spinal proprioception was associated with chronological age, whereas peripheral proprioception was not. Subgroup analyses revealed that subjects aged 10 to 13 years had the poorest proprioceptive performance. The normative values of proprioception of various body parts were, trunk flexion-extension test = 25° ± 12°; trunk lateral-flexion test = 23° ± 10°; trunk axial-rotation test = 26° ± 11°; left neck rotation test = 2° ± 1°; right neck rotation test = 3° ± 1°; left elbow flexion test = 5° ± 3°; right elbow flexion test = 5° ± 2°; left knee extension test = 3° ± 2°; right knee extension test = 3° ± 1°. The normative values of proprioception in position sense provided in this study may help identify individuals with proprioceptive deficits and inform targeted interventions to improve proprioception.
建立规范值并了解本体感觉在身体各部位之间的差异至关重要。然而，个体之间的变异性，尤其是青少年的变异性，使得建立规范变得困难。这阻碍了对本体感觉异常患者进行分类的进一步研究。因此，主要目标是通过三维运动分析来填补知识空白，以捕捉青少年和年轻人的位置感。次要目标是评估位置感与年龄之间的关系，以及不同解剖部位的位置感之间的相互关系。纳入了年龄在10至25岁之间的健康参与者。在躯干、颈部、肘部和膝盖上进行了六项位置感测试。使用三维运动捕捉系统采集数据。本体感觉测量指标是每项测试的绝对重新定位误差（预定起始位置与相应自我再现结束位置之间的差异）。共招募了103名参与者。我们发现只有脊柱本体感觉与实际年龄相关，而外周本体感觉则不然。亚组分析显示，10至13岁的受试者本体感觉表现最差。身体各部位本体感觉的规范值为：躯干屈伸测试=25°±12°；躯干侧屈测试=23°±10°；躯干轴向旋转测试=26°±11°；左侧颈部旋转测试=2°±1°；右侧颈部旋转测试=3°±1°；左侧肘部屈曲测试=5°±3°；右侧肘部屈曲测试=5°±2°；左侧膝关节伸展测试=3°±2°；右侧膝关节伸展测试=3°±1°。本研究提供的位置感本体感觉规范值可能有助于识别本体感觉缺陷个体，并为改善本体感觉的针对性干预提供依据。
