The cavitation sounds heard during chiropractic adjustments of the spine are common phenomena; yet, their location relative to the technique used is relatively untested.
The purpose of this study was to locate the cavitation sounds during the L5 spinous hook adjustment and a lower sacroiliac adjustment. The sounds were analyzed for significant difference in location relative to the 2 techniques.
Thirty asymptomatic volunteers were randomly divided into 2 equal groups. Each group represented either the spinous hook adjustment or lower sacroiliac adjustment. Subjects had 8 microphones taped to their skin, over the relevant facet and sacroiliac joints. Radiographic confirmation was used to ensure optimal placement of the microphones. Sound signals produced during the adjustments were digitized, recorded, and analyzed statistically.
The results indicated that no statistically significant correlation existed between the anatomical location of cavitation sounds and the adjustment technique selected.
Location of cavitation sounds does not appear to have a relationship with type of manipulative technique selected. Further studies using other techniques need to be performed.
在脊椎按摩调整过程中听到的气穴音是常见现象；然而，它们相对于所使用技术的位置相对未经测试。
本研究的目的是确定在L5棘突钩调整和低位骶髂关节调整过程中气穴音的位置。分析这些声音在相对于这两种技术的位置上的显著差异。
30名无症状志愿者被随机分为两组，每组人数相等。每组分别代表棘突钩调整或低位骶髂关节调整。受试者在相关的小关节面和骶髂关节上方的皮肤上粘贴8个麦克风。使用X射线确认来确保麦克风的最佳放置。调整过程中产生的声音信号被数字化、记录并进行统计分析。
结果表明，气穴音的解剖位置与所选调整技术之间不存在统计学上的显著相关性。
气穴音的位置似乎与所选的手法技术类型无关。需要使用其他技术进行进一步研究。
