摘要： 目的探索头部不同屈伸角度对正常青年人静态坐位平衡功能的影响，获得使静态坐位平衡功能最好和最差的头部屈伸角度。方法选取34 名健康在校大学生。受试者闭目，分别取头部中立位、前屈15°、前屈30°、前屈45°、后伸15°、后伸30°，测重心移动轨迹长度。结果重心移动轨迹长度的平均值由小到大依次为：前屈30°、中立位、前屈15°、前屈45°、后伸15°、后伸30°；其中头部前屈30°、中立位、前屈15°时的重心移动轨迹长度均值之间无显著性差异。结论正常青年静态坐位平衡，以头部中立位-前屈30°之间最稳定，头部后伸30°时最差。

Abstract: Objective To investigate the effect of different head flexion/extension angles on static sitting balance in normal youth. Methods34 selected healthy college students were measured with the track length of the centre of gravity under eyes closed, head in a neutral position,flexed in 15°, 30°, 45°, and extended in 15°, 30° (30 s each position). Results the average length from small to big were: head flexedin 30°, neutral position, flexed in 15°, flexed in 45°, extended in 15°, extended in 30°. There was no significant difference among the averagelength when head flexed in 30°, in neutral position and flexed in 15° (P>0.05). Conclusion The static sitting balance is the most whenhead put in neutral position to flexed in 30°, and worst in extended in 30° in healthy youth.

Key words: static sitting balance, head flexion/extension angle, normal youth, track length of the centre of gravity
