iWorx RS-CMAP4-SA 专为研究复合肌肉动作电位 (CMAP) 和神经传导速度而设计。该系统还可用于4通道肌电图 (EMG) 记录，或肌电图和心电图 (ECG) 组合记录。针对啮齿动物和其他小动物的数据记录进行了优化。
产品特征
复合肌肉动作电位 (CMAP) 是神经肌肉电生理研究中的重要指标，指在刺激一条运动神经后，在该神经支配的肌肉上记录到的多个肌纤维动作电位的总和。啮齿动物的 CMAP 研究广泛应用于临床前神经科学和神经肌肉研究，以评估运动神经、神经肌肉接头和肌肉的功能。肌萎缩侧索硬化症 (ALS)、脊髓性肌萎缩症 (SMA)、腓骨肌萎缩症或周围神经病变等啮齿动物疾病模型通常使用 CMAP 来追踪疾病的发生和进展。坐骨神经受挤压或横断后，CMAP 记录可以评估功能性神经恢复的程度和时间。
刺激电极用于刺激特定的神经组织，皮下针式电极放置在受神经支配的肌肉组织上，软件控制电刺激输出，生物电放大器实时记录肌电信号，专业的CMAP高级分析软件模块用于分析波形图。
