在这篇文章中，我们提出了一种新的方法，方便水下肌电测量，而不使用粘合剂防水膜。该方法采用防水绝缘电极和高输入阻抗放大器。组装组件原型，并用于腓肠肌、胫骨前肌和腓骨长肌在水中和水中跖屈时的肌电图测量。8名受试者参加了实验。对于每个测量部位，将水下肌电图（EMG）积分与在水外进行的肌电图积分进行比较，然后计算衰减率。结果表明：（1）8名受试者水下肌电的平均衰减率为-1.58%;（2）根据不同的条件，只有2 ~ 3名受试者在3个部位中的任何一个部位表现出明显的衰减。相比之下，当非防水，一次性电极和市售放大器用于肌电图测量，所有8名受试者在所有三个地点的水下EMG显着衰减，平均衰减率为80.5%。这些结果表明，所提出的方法是有前途的水下肌电测量。此外，它不需要防水准备，这可能会导致皮肤刺激和/或损伤，从而允许更容易的设置。
In this article, we propose a novel method for facilitating underwater electromyographic measurement, without using an adhesive waterproof film. This method employs a waterproofed insulated electrode and an amplifier with high-input impedance. The prototypes of the components were assembled and used for electromyographic measurement of the gastrocnemius, tibialis anterior, and long fibular muscles during plantar flexion both in and out of water. Eight subjects participated in the experiment. For each measurement site, the integrated underwater electromyography (EMG) was compared with that performed out of water, and the attenuation rate was then calculated. The results showed that(1) the mean attenuation rate of underwater EMG among the eight subjects was - 1.58%, and(2) depending on the conditions, only two or three subjects showed significant attenuation at any of the three sites. In contrast, when non-waterproofed, disposable electrodes and a commercially available amplifier were used for electromyographic measurement, all eight subjects showed significant attenuation in underwater EMG at all three sites, with a mean attenuation rate of 80.5%. These results indicate that the proposed method is promising for underwater electromyographic measurement. In addition, it requires no waterproofing preparations, which might cause skin irritation and/or damage, thus allowing easier setup.
