K824 Type Medium Frequency Electrotherapy Device stores 99 specific series program prescriptions internally. Its main feature is multi-step program prescription current therapy, this unique

multi-step program prescription is stored in the computer memory, with the CPU controlling the output of various waveforms (such as square wave, sine wave, exponential wave, tri-

angular wave, spike wave, sawtooth wave) modulated medium frequency current, which then acts on the human body through electrode plates. During the entire treatment process, patients will experience

pushing, grasping, pressing, squeezing, tapping, vibrating, and other sensations. It is precisely this variability that prevents the treated area of the body from easily developing adaptability. Moreover,

within a certain frequency range, the impedance of human tissues is inversely proportional to frequency, so medium frequency current can reach deeper into human tissues

more effectively than low-frequency current, and the skin feels comfortable. Therefore, this multi-step program prescription current therapy has effects such as pain relief, anti-inflammatory, scar softening, muscle

exercise, and improving local blood circulation.
