The relationship between forward head posture (FHP) and thoracic kyphosis has been a subject of interest in the rehabilitation field for visual display terminal workers.
The aim of this study was to investigate the immediate effects of the craniocervical brace use on craniocervical angle (CCA), thoracic kyphosis angle (TKA), and trunk extensor muscle activity.
Twelve young male subjects with forward head posture (21.6±1.9 years) participated in this study. We compared CCA & TKA and trunk extensor muscle activity between with and without application of the craniocervical brace during visual display terminal work.
When wearing the craniocervical brace, the subjects demonstrated significantly greater CCA at the start and the end of the task and less change in CCA during the task (p < 0.05). While non-significantly less TKA was seen at the start of the task, significantly less TKA was observed at the end of the task when using the craniocervical brace (p < 0.05). The craniocervical brace use also led to significantly less change in TKA (p < 0.05). There was no significant difference in the trunk extensor muscle activity.
Use of the craniocervical brace decreased FHP immediately, lessened thoracic kyphosis over time, and prevented the worsening of FHP and thoracic kyphosis during visual display terminal work.
对于从事视觉显示终端工作的人员，头部前倾姿势（FHP）与胸椎后凸之间的关系一直是康复领域关注的课题。
本研究旨在探讨使用颅颈支具对颅颈角（CCA）、胸椎后凸角（TKA）和躯干伸肌活动的即时影响。
12名患有头部前倾姿势的年轻男性受试者（21.6±1.9岁）参与了本研究。我们比较了在视觉显示终端工作期间，使用和不使用颅颈支具时的CCA、TKA以及躯干伸肌活动情况。
佩戴颅颈支具时，受试者在任务开始和结束时的CCA显著增大，且任务期间CCA的变化较小（p<0.05）。虽然在任务开始时TKA略有减小但无统计学意义，但在任务结束时使用颅颈支具时观察到TKA显著减小（p<0.05）。使用颅颈支具还导致TKA的变化显著减小（p<0.05）。躯干伸肌活动没有显著差异。
使用颅颈支具可立即减少FHP，随着时间推移减轻胸椎后凸，并在视觉显示终端工作期间防止FHP和胸椎后凸恶化。
