<![CDATA[The use of medical equipment in the world of health is very much needed, one of which is an electrostimulator which can be used to help recovery in post-stroke patients. Electrostimulators can be made with several conditions, namely: controller, stimulator, and electrodes. Apart from that, there are 4 parameters needed for the electrostimulator, namely 1) Pulse Amplitude, 2) Pulse Width, 3) Pulse Shape, 4) Pulse Frequency. In this electrostimulator, it is highly recommended to use a surface electrode, apart from being a non-invasive electrode, this electrode also provides comfort and is easy to use. Judging from this, an innovation was carried out, namely making an electrostimulator with the choice of 2 modes, namely continuous and intermittent. The research procedure was carried out in several stages starting from preparing tools and materials, measurements and functional tests. The results of the research are a design for an electrostimulator therapy device with a power supply connected to a microcontroller and displayed on an LCD. The test results showed that the error percentage at the power supply input was 5.9%, the power supply output was 3%, and the buzzer output was 0%. The results of testing and analysis of the tool on the oscilloscope showed that the error percentage at frequency values of 2 Hz, 4 Hz, 5 Hz, 7 Hz and 8 Hz was 0.05%, 0%, 2%, 4% and 8% respectively. Based on the results of this research, it can be concluded that the tool is as desired and good to use.]]>
