HiDow markets medical solutions that include a Class II medical device that is approved and licensed by the US Food and Drug Administration, SA Department of Health, and Conformité Européenne. Side effects entailed to a TENS unit are very rare; however, our devices cannot be used by any individual impacted by the following medical conditions.


Pacemaker and Severe Heart Disorders

It is possible that TENS therapy can interfere with an implanted medical device. You should avoid any TENS unit if you have a pacemaker or heart disease. Electrical currents generated from TENS units can interfere with the functionality of the pacemaker which can possibly ruin the implanted device and can put yourself at risk.

While some pacemakers are made safe with TENS therapy, it’s best to speak to a healthcare professional before trying the device.



If you’re pregnant, or think you’re going to get pregnant, you should avoid using a TENS unit. To be clear, pregnant women are not at risk when opting for electrotherapy. But the effects of TENS therapy to an unborn child can pose risks which is why you should avoid it.

You may use electrotherapy under the supervision of your practitioner. However, even with this intention, you should avoid it during the first and second trimester. Also, never place the electrodes above the uterus.


Epilepsy and Seizures

While the research is still inconclusive, there is a possibility that electrical currents can trigger epileptic episodes and seizures. Some medical professionals warn to avoid it while others suggest to practice caution.

For safety reasons, do not use them to avoid any episodes.



TENS therapy influences the circulatory system which can causes issues within the lymphatic system and can cause additional fluid retention. Because lymphedema compromises the skin’s integrity and causes swelling, it is advisable to only use TENS units on healthy skin.

Cochlear Implant

Electrical currents from TENS devices can adjust the frequency of your cochlear implants resulting for a re-tune. Simply put, this can alter the cochlear implant’s maps. A medical professional will have to reprogram them leaving you deaf for the time-being.

Side-effects to TENS therapy is rare, but if you have any conditions mentioned above, you should not use electrotherapy devices. You should also avoid it if you have the following:

  • Deep vein thrombosis (DVT)

  • Cancer or are recovering from cancer

  • Any electronic implanted device

  • Plates in your body and/or titanium screws and/or pins


Important: Never place gel pads or accessories directly on your heart or the temple region on either side of your head. If you are unsure, please, consult with your doctor before using our device.


1. Place both electrode pads on the area of your body where you are experiencing stress, stiffness, aches or pain.
2. Set the unit to the mode and intensity level that fits your personal preference.
Always start at the lowest intensity first and work up. Never start at a very high intensity level.
3. Sit back and enjoy the deep, relaxing sensations of your HiDow electronic muscle stimulator.

Never place electrode pads on the following areas:

  • Sinus nerves

  • Throat or mouth

  • Temples or around the brain

  • Swollen, Infected, or Inflamed areas

  • Skin eruptions

  • Cancerous lesions

  • Directly on your heart

Extending the life of your electrodes:

  • Attach your electrodes to pads before you remove the plastic protector cover and before you place it on your body.

  • Don’t touch the gel on the pads as this will reduce the life of your pads. Your pads are reusable so please don’t throw them away after use. Before you place your pads on the area to be treated put a few drops of water on the pads to improve adhesiveness to your skin.

Charging Your Device

  • The lithium battery can be recharged through both AC adapter and USB cable.

  • While charging, the screen in ON position indicates the charge, while in OFF position the screen is blank.

  • The battery will charge in either one of the power positions (ON or OFF).

  • The battery should be charged for 8-10 hours before first use.

  • The device battery is built into our HiDow devices and is non-removable.

HiDow Maintenance and Care

  • Make sure your skin is free from any dirt, oil, or lotions.

  • Before applying the gel pads, put a few drops of water on your fingers and rub them on both pads. This will help the gel pads maintain their adhesiveness.

  • When you finish using the device, turn it off.

  • Take off the gel pads.

  • Place the protective films back on the gel pads or place them on the pad holder.

  • Take the electrode wires out from the device and place back in the box until next use.

  • Store your HiDow device in a cool, dry place until next use.

  • TENS – Transcutaneous Electrical Nerve Stimulation
    TENS is a therapy that has been around for years and used to treat nerve related pain conditions. Prescribed by doctors, physical therapists, pain management clinics and personal trainers since the 1960s, TENS units uses low-voltage electrical pulses to interrupt pain signals before they reach the brain through soothing pulses that simulate natural painkillers, called endorphins.
  • What kind of pain conditions does TENS target?
    TENS provides pain relief for many different types of conditions and illnesses, including, but not limited to, pulled or strained muscles, tendinitis, bursitis, lower back pain, osteoarthritis, fibromyalgia, bone pain, and diabetic peripheral neuropathy. In addition, TENS is often used by fitness and sports enthusiasts to provide relief for post-workout pain or soreness and to help muscles relax and recover.
  • How does TENS work?
    Using the HiDow TENS unit of your choice is easy. Gone are the days when these units were bulky, costly, and only available by prescription. HiDow TENS units are a real game-changer: portable, hands-free and rechargeable with a streamlined, modern look. To get started, you simply connect the electrodes from the small, battery-powered machine to your skin, using reusable and self-adhesive silicon electrode gel pads as the conduit. By doing so, you create a circuit of electrical impulses that painlessly travel along your nerve fibers.
  • Is it possible to customize the TENS unit?
    Many TENS units from HiDow’s product portfolio can be customized to your preferences, thanks to a variety of wavelength frequencies. Choose from intensities of current or even a stable flow of pulses. For optimal results, consult with your doctor to see which settings are the best for your pain management.
  • Is using a TENS unit safe?
    The treatment is generally very safe and relief is almost immediate. Using HiDow TENS gives you freedom from drugs that often come with side effects. If you’re seeking pain management or fast relief, TENS can be a used instead of, or in addition to, medication.
  • Can TENS augment physical therapy?
    Absolutely. You can use TENS therapy between your physical therapy sessions, right in the comfort of your own home. The HiDow TENS unit could even strengthen the results you get from your physical therapy by facilitating movement between sessions.
