6. Modes and Applications

The BHK-TENS 280 offers 24 pre-programmed modes, combining TENS, EMS, and massage therapies. These modes are designed to target various types of pain and muscle conditions across different body parts.

6.1 TENS (Transcutaneous Electrical Nerve Stimulation)

TENS therapy is primarily used for pain relief by sending low-voltage electrical currents through the skin to stimulate nerves, blocking pain signals to the brain. It is effective for chronic and acute pain conditions.

6.2 EMS (Electrical Muscle Stimulation)

EMS therapy uses electrical impulses to stimulate muscle contractions, which can aid in muscle strengthening, rehabilitation, and preventing muscle atrophy. It helps improve and facilitate muscle performance.

6.3 Massage

The massage modes provide gentle electrical pulses to relax muscles, reduce tension, and improve circulation, offering a soothing effect similar to traditional massage.

6.4 Recommended Application Areas

The device can be used for various body parts, including but not limited to:

• Neck
• Shoulders
• Back (upper, middle, lower)
