Abstract
Objective To investigate the effect of different head flexion/extension angles on static sitting balance in normal youth. Methods 34 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 flexed in 30°, neutral position, flexed in 15°, flexed in 45°, extended in 15°, extended in 30°. There was no significant difference among the average length when head flexed in 30°, in neutral position and flexed in 15° (P>0.05). Conclusion The static sitting balance is the most when head put in neutral position to flexed in 30°, and worst in extended in 30° in healthy youth.关键词
