To localize the facet joints that give rise to the cracking sounds caused by cervical rotatory and local manipulation.
Cervical rotatory and local manipulation was performed in 30 healthy adults at the spinous process at the C(4 )level once on each of the left and right side, and a set of equipment we designed for acoustic signal acquisition was applied to collect and locate the cracking sounds, followed by statistical analysis of the data collected.
The cracking sounds caused by cervical rotatory and local manipulation were localized mainly at C(3-7) facet joints, and the times of cracking sounds at these facet joints had significant differences from those at the other facet joints.
The location of cervical rotatory and local manipulation can be only relative, and definite localization seems impossible.
确定导致颈椎旋转和局部手法操作时出现弹响声的小关节。
对30名健康成年人在C4棘突水平的左右两侧各进行一次颈椎旋转和局部手法操作，并使用我们设计的一套声学信号采集设备收集并定位弹响声，随后对所收集的数据进行统计分析。
颈椎旋转和局部手法操作引起的弹响声主要定位在C3-7小关节，这些小关节处的弹响次数与其他小关节处的弹响次数有显著差异。
颈椎旋转和局部手法操作的定位可能只是相对的，似乎无法进行确切定位。
