ITO TENS 120Z: Palm-Sized Precision Pain Relief Stimulator
The gold standard in clinical-grade portable TENS therapy, combining dual-channel independent amplitude dials, adjustable pulse frequency, and durable Japanese engineering for hospital and home rehabilitation.
• Biophysical Mechanism: Melzack-Wall Gate Control & Endorphin Release
Spinal Gate Mechanism
High-frequency TENS (80–120 Hz) selectively stimulates large myelinated A-beta cutaneous sensory fibers, exciting inhibitory interneurons in the dorsal horn substantia gelatinosa to block nociceptive C-fiber signals from ascending to the brain.
Endogenous Opioid Modulation
Low-frequency TENS (2–10 Hz) triggers the descending pain inhibitory pathways in the brainstem, stimulating central release of beta-endorphins and met-enkephalins for prolonged systemic pain modulation.
Key Clinical Innovations & Advantages
Pocket-Sized Ergonomics
Weighing only 120g with built-in belt clip, enabling continuous patient ambulation and active home-care pain control.
Independent Intensity Knobs
Dedicated rotary dials for channels A and B allow micro-adjustment of current intensity with zero accidental jumps.
Constant, Burst & Modulated
Select Constant mode for acute pain, Burst mode for chronic musculoskeletal tension, or Modulated mode to prevent nerve accommodation.
Drop-Resistant Build
Precision industrial molding and robust jack sockets built to withstand rigorous clinical daily handling.
