Deep tissue penetration, precise action range

Medium frequency current penetrates 2-5cm into deep tissues (low-frequency current only acts 0.5-1cm under the epidermis), directly stimulating muscles, nerves, and joint synovium. It’s particularly effective for deep soft tissue injuries like lumbar muscle strain or knee arthritis. With "directional current conduction technology", it focuses on pain points (e.g., nerve root compression in lumbar disc herniation), reducing interference with surrounding tissues, with 60% higher precision than low-frequency devices.

Multi-waveform modulation, adaptable to various symptoms

Using "medium-frequency carrier + low-frequency modulation" technology, it generates 8-12 waveforms (continuous, intermittent, dense-sparse waves, etc.) for different symptoms: intermittent waves for muscle weakness recovery, dense-sparse waves for chronic pain relief, continuous waves for blood circulation promotion. Clinical data shows 92% efficacy in sciatica with dense-sparse waves, higher than 78% with single waveforms.

Low skin irritation, suitable for long-term use

Medium frequency current uses "capacitive reactance penetration" (instead of low-frequency resistance conduction), avoiding strong stimulation to epidermal nerve endings, with only mild warmth or soreness. Friendly to sensitive skin, the elderly, and children (e.g., auxiliary treatment for infant torticollis), usable 1-2 times/day (15-30min/session) for 4-6 weeks without adaptation (unlike low-frequency devices with reduced efficacy due to nerve adaptation).
