Neuromodulator treatments limit the contractility of the frontalis muscle, resulting in reduced dynamic and static horizontal forehead line formation of the overlying skin. This interventional study investigated the electrophysiologic response (via signal-to-noise [SNR] ratio) and the overlying skin displacement of the frontalis muscle following neuromodulator injections in a total of 11 healthy neuromodulator-naïve volunteers. Relating SNR to the respective skin movement revealed that the higher the SNR, the more vertical the skin displacement is; this remained statistically relevant after gender stratification. These results are novel and will help the aesthetic community to understand neuromodulator effects on the frontalis muscle.
神经调节剂治疗会限制额肌的收缩能力，导致覆盖其上的皮肤的动态和静态水平额纹线形成减少。这项介入性研究共调查了 11 名从未接受过神经调节剂治疗的健康志愿者在接受神经调节剂注射后的额肌的电生理反应（通过信噪比[SNR]比）和覆盖其上的皮肤位移。将 SNR 与各自的皮肤运动相关联，结果表明 SNR 越高，皮肤位移越垂直；这在按性别分层后仍然具有统计学意义。这些结果是新颖的，将有助于美容界了解神经调节剂对额肌的影响。
