The purpose of this study was to measure the forces exerted during spinal manipulative therapy of the thoracic spine simultaneously with corresponding cavitation signals. Forces were measured using a thin, flexible pressure mat which was placed on patients over the contact area between doctor and patient. Cavitation signals were measured using a skin mounted accelerometer on the spinous process of a vertebral body adjacent to the manipulated vertebral body. Mean forces of spinal manipulative therapy at the instant of cavitation were 364 N with a standard deviation of 106 N. These values are considerably larger than corresponding values reported for cavitation at metacarpophalangeal joints. The precise factors causing cavitation of the spinal joints could not be determined. Study designs which may allow identification of these factors are suggested.
本研究的目的是在胸椎脊柱手法治疗过程中，同时测量施加的力与相应的关节松动信号。使用一个薄的、柔性压力垫测量力，该压力垫放置在患者身上医生与患者的接触区域。使用安装在与被手法治疗椎体相邻椎体棘突上的皮肤加速度计测量关节松动信号。关节松动瞬间脊柱手法治疗的平均力为364N，标准差为106N。这些值远大于掌指关节关节松动所报告的相应值。无法确定导致脊柱关节关节松动的确切因素。提出了可能有助于识别这些因素的研究设计。
