简要总结
The objective of the present study is to determine if spinal manipulations with a constant rate of force application but with different peak force and time to peak force lead to similar responses in healthy adults.
详细描述
Although there are indirect evidences that the rate of force application modulates neuromuscular responses to spinal manipulation therapy (SMT) through peak force or thrust duration modulations, such an assumption remains to be confirmed. Therefore, the objective of the present study was to determine if different SMT force-time profiles where a constant rate of force application would be maintained (through the modulation of the peak force and the time to peak force) lead to similar neuromechanical responses. Based on the available data relative to the effect of SMT biomechanical parameters modulation, it was hypothesized that neuromuscular responses would be similar across SMT force-time profiles, while vertebral displacements would increase as SMT peak force increases.

主要结局
Left T6 Normalized Root Mean Square (RMS) Value
时间窗: During the 300N spinal manipulation procedure, assessed up to 2 seconds following thrust onset
Normalized amplitude (RMS) of surface electromyography response. The normalisation was achieved by dividing the obtained RMS by the RMS value before thrust application.
Left T8 Normalized Root Mean Square (RMS) Value
时间窗: During the 300N spinal manipulation procedure, assessed up to 2 seconds following thrust onset
