2.结果综合所有受试者(n=16)，VS-Tacs和AM-Tacs的手指运动间隔分布呈右倾(图1B)，这在以前的自愿行动研究中是常见的。VS-TAC组手指运动间隔为12.0±5.9秒，AM-TAC组为11.6±6.2秒。两组间差异无统计学意义(t检验，p=0.253)。卡方检验表明，在VS-TAC(图1C)中，运动起始的分布明显偏离均匀(p=0.027)。这一运动最常在π/2-π发起。在AM-TAC中，运动起始的分布没有明显偏离均匀度(p=0.620)。相对于肌电(EMG)起始点的平均VS-TAC在其前面显示一个逐渐上升的波形(图1D)，这与MRCP的波形相似[1]。从肌电开始前的1.68秒开始，它明显偏离了95%的可信区间。讨论
2. ResultsWhen pooled across all participants (n= 16), the distribution of intervals between finger movements in both VS-tACS and AM-tACS showed a rightward skew (Fig. 1 B), which was commonly observed in previous voluntary action studies. The intervals between finger movements were 12.0±5.9 seconds in VS-tACS and 11.6±6.2 seconds in AM-tACS. They were not significantly different (t-test, p= 0.253). Chi-square test demonstrated that the distribution of movement initiation was significantly departed from uniformity (p= 0.027) in VS-tACS (Fig. 1 C). The movement was initiated most frequently in π/2–π. In AM-tACS, the distribution of movement initiation was not significantly departed from uniformity (p= 0.620). The averaged VS-tACS with respect to the electromyography (EMG) onset showed a gradually rising waveform preceding it (Fig. 1 D), which is similar to the waveform of MRCP [1]. It deviated significantly from the 95% CI approximately from 1.68 seconds prior to the EMG onset.3. Discussion
