The RoovJoy 3-in-1 is a dual-channel output TENS, EMS and Massage stimulator.
The RoovJoy 3-in-1 belongs to the group of electrical stimulation systems.
It has three basic functions–TENS (Transcutaneous Electrical Nerve Stimulation), EMS (Electronic Muscle Stimulation) and Massage.
The device has 22 programs (9 TENS programs, 8 EMS programs and 5 Massage programs) and applies electric currents in the low-frequency range for therapy. Each program controls the generated electric impulses, their intensity, frequency and pulse width. Based on stimulating the body’s natural pulses, the mechanism of electrical stimulation equipment is to create electric impulses that are transcutaneous transmitted to the nerves or muscle fibres through electrodes.
The intensity of the RoovJoy 3-in-1 can be adjusted independently and can be applied individually to one body part. The RoovJoy 3-in-1 can be used with four electrodes, which allows you to stimulate one muscle group simultaneously with a wide selection of standard programs. The electrical pulse is first transmitted to the tissue, then it affects the transmission of stimulation in nerves as well as muscle tissues in the body.

Features:
The TENS (Transcutaneous Electrical Nerve Stimulation) function provides fantastic relief for joint pain, muscle soreness, arthritis, and more.
The EMS (Electric Muscle Stimulator) mode specializes in increasing blood flow, preventing/relieving soreness, muscle strengthening, and active recovery for post-workout.
The massage mode provides soothing relief for sore muscles, assists with healing and also increases blood flow.
The RoovJoy 3-in-1 also features an easy to use operating system, that is easy to learn.
