How to choose

  • Channels and Pads. The number of channels determines how many areas you can treat simultaneously. Two channels allow for four pads, enabling bilateral treatment or targeting multiple sites.
  • Waveform and Modes. Different pulse patterns like burst, continuous, or modulated target different pain types. EMS modes cause muscle contractions for recovery, while TENS focuses on pain gate control.
  • Intensity and Adjustability. Look for devices with multiple intensity levels (15+) for fine-tuning comfort. Adjustable pulse width and rate offer personalized relief, especially for deep or acute pain.
  • Portability and Power. Consider battery type and size if you travel. Wireless units offer convenience, but wired devices often have longer battery life and stronger output.
  • Electrode Quality and Availability. Standard reusable adhesive pads vary in longevity. Check if replacement pads are easily sourced. Some devices include gel-free pads or different sizes for specific body parts.
