Frequently Asked Questions

Product information

Are DR-HO’S products safe?

DR-HO’S electrical stimulation devices are pain relief medical devices that are FDA cleared and authorized by Health Canada and are completely safe to use. It is, however, not recommended for people with pacemakers, infants, and pregnant women. For those who are epileptic or if you have any concerns with a specific medical condition, we always recommend you consult with your doctor or healthcare practitioner.

Are DR-HO’S devices drug-free?

Yes, DR-HO’S electrical stimulation devices are completely drug-free solution to help you manage your pain and can be used in combination with your medications. They do not require any over the counter or prescription drug supplements in order to be effective. If you have any health concerns or are unsure about alternative therapies then it’s always a good idea to consult your healthcare provider when starting any new forms of therapy to ensure that it’s the correct solution for you.

Do I need to use gel on the gel pads?

The gel pads can be used on any body part to provide you with a comforting massage and to help relieve your pain. They comfortably conform to your body and allow the electrical stimulation to effectively relieve your pain. Simply ensure that the pads are nice and sticky before use or add some water to them before you start.

Are DR-HO’S products clinically tested?

DR-HO'S products are clinically tested to relieve pain, reduce muscle tension and spasms, increase tissue oxygenation and improve circulation. The Pain Therapy System was part of a scientific study conducted by Dr. Stuart M. McGill, Ph.D. and commissioned by Dr. Michael Ho. You can view the full study here.

Does the stimulation hurt?

The stimulation from our devices is very gentle and comfortable. In fact, the different modes in our devices feel like you’re getting a massage such as kneading, chopping, or fingers gently running over your muscles. You are in control of the stimulation and increase or decrease the intensity as you require. For best results, we recommend that the gel pads feel nice and sticky to enhance the feeling of the stimulation and when using the fabric electrode make sure to add enough of the electrode gel before using the device.

How long does it take the devices to start working?

DR-HO’S devices will start working right away. The stimulation from our devices will contract the muscles to help them relax but more importantly, help to increase circulation to relieve your pain. Remember pain doesn’t disappear overnight so for the best results we recommend that you use our devices daily at least 3-5 times a day for the best results and you will notice a difference within a short period of time.


What makes DR-HO'S devices different?

Most competing TENS machines block pain at first, but within several minutes the pain persists. These TENS machines offer a single, predictable mode of electrical stimulation. The body learns to bypass this stimulation and continues to deliver pain signals to the brain. Dr. Michael Ho worked with a team of skilled engineers to create a device that could prevent neural adaptation. All of DR-HO’S devices utilize TENS, EMS, and NMES to deliver different combinations of electrical stimulation with modulated frequencies, wave durations, and waveforms. We refer to this proprietary type of stimulation as Auto-Modulating Pulse (AMP). This means no matter how long you use a DR-HO’S device, the pain will be kept at bay. All of DR-HO’S massage modes deliver the electrical stimulation in different frequencies so the pain signals continue to be blocked. The auto-modulating waves are the key differentiator between DR-HO’S and other TENS and electrical stimulation machines available for sale.

What is AMP Technology?

DR-HO’S AMP Technology stands for Auto-Modulated Pulse. AMP Technology utilizes three different electrical stimulation modalities known as TENS, EMS, and NMES to provide a comprehensive approach to pain management. AMP takes it a bit further by providing over 300 different types of electrical stimulations that randomly change every few seconds to avoid muscle adaptation. In addition, AMP varies the intensity, waveform duration, and waveform frequencies so that you can use our device on a regular basis.

What is TENS therapy?

TENS machines are a safe, powerful alternative to harsh drugs or invasive treatments. DR-HO’S TENS machines help people experience clinically-tested pain relief from the comfort of their home. TENS machines work by sending electrical impulses to the sensory nerves that block pain signals from reaching the brain. This provides a natural analgesia in the body without the need to ingest medication or undergo manual manipulation or surgery. TENS therapy machines can help relieve pain associated with chronic and acute conditions such as headaches, migraines, neck pain, shoulder pain, back pain, sciatica, leg pain, lower limb pain, foot and ankle pain, poor circulation, fibromyalgia, joint pain, carpal tunnel syndrome, sciatica, athletic or exercise injuries and more.
