Currently, many electromyographs in Japan are used for diagnosis and research purposes and are difficult to manipulate for ordinary users. If the electromyograph becomes a familiar tool, electromyogram information can be used as a common language for exercise guidance, and electromyogram biofeedback using them in daily life. Besides, it is expected that it can be used in various situations such as exercise for health promotion, sports, preventive medicine, and rehabilitation in the community. In this symposium, the introduction of low-cost simple electromyographs that can be manufactured using mobile terminals such as smartphones were presented.
Next, the results of its validity and reliability tests, application examples in clinical settings, and educational settings were showed. In this way, it is expected that simple electromyographs by using an existing smartphone as a monitor will become popular as a familiar measurement tool in Japan. Also, using low-cost devices such as low-cost simple electromyographs that are easy to reach for users, I hope that the time will come when “visualization” will be made, and quantitative exercise guidance will be implemented.
