TENS and EMS unit for pain relief and muscle stimulation. There are replacement pads with different shapes and sizes in the package. This electronic pulse massager is made by HealthmateForever, model number PRO24AB. TENS stands for Transcutaneous Electrical Nerve Stimulation, and EMS stands for Electrical Muscle Stimulation. Basically, TENS stimulates the nerves and by this relieving the pain, while EMS stimulates the muscles, making them grow. Some more cables and HealthmateForever replacement sticking pads. This is the charger, which is used to charge the built-in battery. This means that the TENS unit is wireless, and the only thing it is connected to is your body. The electric muscle stimulator is small and portable, and the design is pretty stylish. It has two channels, each of which can support up to 4 sticking pads. An on/off switch and a mini USB charging port on the top. There are 24 different massaging modes. As you can see, I am testing the massager on my shoulder, since I have been having some shoulder pain for a while now. But you can use it on any part of your body, such as your back, your neck, your knee, or even your feet. The different massaging modes release the electrical impulses in different manners. Subscribe!
