7. Modes Description
The device offers three distinct modes, each with specific benefits:
- TENS (Transcutaneous Electrical Nerve Stimulation) - Modes 1-20: Primarily used for pain relief. TENS works by sending gentle electrical impulses through the skin to block pain signals from reaching the brain and stimulating the body's natural pain-relieving endorphins.
- EMS (Electrical Muscle Stimulation) - Modes 21-40: Designed to relax muscle spasms and improve muscle performance. EMS causes muscles to contract and relax, which can help with muscle recovery, reduce soreness, and improve circulation.
- FITNESS - Modes 41-50: Specialized for muscle toning and strengthening, particularly abdominal muscles. This mode helps to improve muscle development and create a firmer appearance.
8. Electrode Pads
The LIORQUE Electrostimulator comes with high-quality electrode pads designed for durability and effective conductivity.
