Quanrike J48B Computer Medium Frequency Therapy Apparatus, developed based on the theory of medium frequency pulse electrical stimulation, is a medical-grade therapy device. It integrates years of clinical experience from numerous domestic experts and professors, storing 99 treatment programs for common diseases in its computer system. Each program utilizes at least 30 different output waveforms and frequency variations, allowing the human body to experience sensations such as massage, pressing, tapping, pulling, flowing, and vibration. Within 20 minutes, it can induce muscles to perform over 1,000 contractions of various types—fast, slow, clonic, and tonic—significantly outperforming single-parameter medium or low-frequency electrotherapy methods.
