The aim of this study was to determine the variability of the thrust parameters produced by practitioners performing a high velocity spinal manipulative therapy technique (toggle-recoil) normally applied to the neck. Fourteen participants performed three thrust trials, separated by >30minutes, on a patient simulation device. Force and displacement generated during the thrusts were simultaneously recorded and analysed off line. Peak thrust force ranged from 18.2 to 246N with a mean of 111.2N (SD 48.8). Time to peak thrust force ranged from 20 to 100ms, mean 67.5 ms (SD 13.1). Peak thrust displacement ranged from 6.1 to 28.9mm, mean 24.1mm (SD 4.9) and time to peak thrust displacement ranged from 22.5 to 105ms, mean 59.4ms (SD 13.8). This study demonstrates that the force and displacement induced by any individual practitioner on a simulator can vary by up to 50% during a toggle-recoil thrust. Furthermore, different practitioners may vary in their force by as much 100% and in displacement by 50% when the toggle-recoil spinal manipulative procedure is performed.
本研究的目的是确定从业者在对颈部正常应用高速脊柱手法治疗技术（肘节式反冲法）时所产生的推力参数的变异性。14名参与者在患者模拟装置上进行了三次推力试验，每次试验间隔超过30分钟。在推力过程中产生的力和位移被同时记录下来并离线分析。峰值推力从18.2牛至246牛不等，平均为111.2牛（标准差48.8）。达到峰值推力的时间从20毫秒至100毫秒不等，平均为67.5毫秒（标准差13.1）。峰值推力位移从6.1毫米至28.9毫米不等，平均为24.1毫米（标准差4.9）；达到峰值推力位移的时间从22.5毫秒至105毫秒不等，平均为59.4毫秒（标准差13.8）。本研究表明在肘节式反冲推力过程中，任何一名从业者在模拟器上所诱导的力和位移的变化幅度可高达50%。此外，在进行肘节式反冲脊柱手法操作时，不同从业者的力的差异可能高达100%，位移差异可达50%。
