EMS refers to a technology that sends mild electrical impulses through electrodes (pads or built-in components) to specific muscles. These impulses cause the muscles to contract involuntarily, mimicking the signals your brain sends during natural movement or exercise.

Key aspects and uses of EMS in massagers:

• Muscle Contraction: The primary function is to cause muscles to contract and relax rhythmically.

• Muscle Strengthening & Toning: It can help to strengthen weak muscles, improve muscle tone, and prevent muscle atrophy (wasting away due to inactivity).

• Rehabilitation & Recovery: Often used in physical therapy to aid in muscle recovery after injury or surgery, improve circulation, and reduce swelling.

• Pain Relief (Indirectly): While TENS (Transcutaneous Electrical Nerve Stimulation) is primarily for pain relief by blocking nerve signals, EMS can indirectly help pain by reducing muscle spasms, tension, and improving blood flow.

• Enhanced Blood Flow: The muscle contractions stimulated by EMS can help increase local blood circulation, which aids in recovery and healing.

• Relaxation: By promoting muscle contraction and then relaxation, it can help release tension and contribute to overall muscle relaxation.
