Abstract:
UNASSIGNED: High velocity thrust manipulation is commonly used when managing joint dysfunctions. Often, these thrust maneuvers will elicit an audible pop. It has been unclear what conclusively causes this audible sound and its clinical meaningfulness. This study sought to identify the effect of the audible pop on brainwave activity directly following a prone T7 thrust manipulation in asymptomatic/healthy subjects.
UNASSIGNED: This was a quasi-experimental repeated measure study design in which 57 subjects completed the study protocol. Brain wave activity was measured with the Emotiv EPOC+, which collects data with a frequency of 128 HZ and has 14 electrodes. Testing was performed in a controlled environment with minimal electrical interference (as measured with a Gauss meter), temperature variance, lighting variance, sound pollution, and other variable changes that could have influenced or interfered with pure EEG data acquisition. After accommodation each subject underwent a prone T7 posterior-anterior thrust manipulation. Immediately after the thrust manipulation the brainwave activity was measured for 10 seconds.
UNASSIGNED: The non-audible group (N = 20) consisted of 55% males, and the audible group (N = 37) consisted of 43% males. The non-audible group EEG data revealed a significant change in brain wave activity under some of the electrodes in the frontal, parietal, and the occipital lobes. In the audible group, there was a significant change in brain wave activity under all electrodes in the frontal lobes, the parietal lobe, and the occipital lobes but not the temporal lobes.
UNASSIGNED: The audible sounds caused by a thoracic high velocity thrust manipulation did not affect the activity in the audible centers in the temporal brain region. The results support the hypothesis that thrust manipulation with or without audible sound results in a generalized relaxation immediately following the manipulation. The absence of a significant difference in brainwave activity in the frontal lobe in this study might indicate that the audible pop does not produce a \"placebo\" mechanism.
摘要:
在管理关节功能障碍时,通常使用高速推力操纵。通常,这些推力机动会引起一声爆音。目前尚不清楚是什么最终导致了这种可听声音及其临床意义。这项研究旨在确定无症状/健康受试者在俯卧的T7推力操纵后直接听得见的流行音乐对脑电波活动的影响。
这是一项准实验性重复测量研究设计,其中57名受试者完成了研究方案。使用EmotivEPOC测量脑电波活动,它以128HZ的频率收集数据,并有14个电极。测试在受控环境中进行,电干扰最小(用高斯计测量),温度方差,照明变化,声音污染,以及其他可能影响或干扰纯EEG数据采集的变量变化。适应后,每位受试者都进行了俯卧的T7前后推力操作。在推力操纵之后立即测量脑电波活动10秒。
非听觉组(N=20)由55%的男性组成,可听组(N=37)由43%的男性组成。非听得见的组脑电图数据显示,额叶某些电极下的脑电波活动发生了显着变化,顶叶,和枕叶。在可听的组中,额叶所有电极下的脑电波活动都有显著变化,顶叶,和枕叶,而不是颞叶。
由胸部高速推力操纵引起的可听声音不影响颞脑区域可听中枢的活动。结果支持以下假设:有或没有声音的推力操纵会导致操纵后立即产生广义松弛。在这项研究中,额叶的脑电波活动没有显着差异,这可能表明可听见的流行音乐不会产生“安慰剂”机制。
