K8832-TMedium Frequency Electrotherapy Device is a medical device used for physical therapy.
This unit employs microcomputer control technology, composed of medium and large-scale integrated circuits, featuring dual-channel synchronous or asynchronous output. The output current intensity is adjusted via increment and decrement buttons (200 levels, 0.5mA per level), and includes various display functions.

The device stores 90 specific series program prescriptions, 20 of which are multi-step program prescriptions. This innovative multi-step program current therapy is a classic summary derived from years of clinical research by physical therapy experts. Waveform data and various treatment parameters are stored in the computer memory in the form of prescriptions. The CPU controls the output of medium-frequency currents modulated with various waveforms (such as square wave, sine wave, exponential wave, triangular wave, spike wave, sawtooth wave), which are then applied to the human body through electrode pads. During the entire treatment process, patients may experience various sensations such as pushing, grasping, pressing, squeezing, tapping, and trembling. It is this variability that prevents the treated area from developing adaptability. Within a certain frequency range, the impedance of human tissues is inversely proportional to frequency, so medium-frequency currents can penetrate deeper into human tissues than low-frequency currents, while also providing a comfortable skin sensation. Therefore, this multi-step program current therapy has effects such as pain relief, anti-inflammatory action, scar softening, muscle exercise, and improvement of local blood circulation. The device also features interferential current therapy and iontophoresis functionality.
