How does a TENS unit work?
TENS units have different adjustable settings to control the amplitude (intensity) of stimulation by controlling the voltage, current, and pulse width (duration) of each pulse. Electrodes are placed at specific sites on a user’s body depending on the physical location of their pain. The current travels through electrodes and into the skin, stimulating specific nerve pathways to produce a tingling or massaging sensation that reduces the perception of pain. When used as directed, a TENS unit is a safe, non-invasive, drug-free method of pain management, offering a better quality of life for people with pain. There are two main ways TENS can successfully decrease or eliminate pain.
What is the difference between a TENS and EMS unit?
TENS Unit (Transcutaneous Electrical Nerve Stimulation) can help with back and neck pain caused by trauma or continuous strain. Muscle guarding in response to pain impairs circulation and leads to waste product accumulation. TENS therapy helps break this cycle, aiding the normal healing process.
EMS (Electrical Muscle Stimulation) helps relieve pain, reduce spasms, tone muscles, and assist healing. EMS increases blood circulation and treats muscles rather than nerves, reducing swelling and muscle inflammation that may negatively affect joints.
How does an EMS unit work?
When exercising, the brain sends messages to muscles through nerves to contract. An EMS unit uses electrical impulses to mimic this process, stimulating muscles that may not be voluntarily exercised, allowing training of less active muscles.
What unit would be best for me?
Consult your doctor or physical therapist to determine which features you need for the best results from TENS or EMS therapy. Consider factors such as battery life, controls, and cost-effectiveness when choosing a unit.
Is a prescription required in order to purchase a unit?
Some states require a prescription for owning a TENS unit. Check with your doctor regarding your state's regulations. While we do not require a prescription for purchase, you may need one for your records.
Do you accept insurance?
We are not set up to accept medical insurance, including FSA/HSA debit cards. However, many customers have successfully arranged for reimbursement from their insurance providers. Contact your provider to explore this option.
What units are FDA approved?
All TENS and EMS units are FDA approved.
Are the electrodes compatible with a unit?
As long as electrodes have standard connectors, they should be compatible with your unit.
Where do I place the electrodes?
This link has an electrode placement chart, including instructions on skin care and application of reusable self-adhesive electrodes.
How long do the electrodes usually last?
The lifespan of electrodes depends on factors like usage time, body hair, and humidity. Alternating between two sets of electrodes and allowing them to dry completely can extend their usage. Following the instructions on the electrode bag will also help maximize their lifespan.
When should I replace my electrodes?
Replace electrodes when they no longer stick firmly, have been re-applied more than the recommended number of times, or are not conducting effectively.
Can a unit be used if you have a pacemaker or defibrillator?
You cannot use a TENS or EMS unit if you have a pacemaker or implantable cardioverter-defibrillator.
Can you use a TENS or EMS unit while pregnant?
No, you cannot use a unit while pregnant.
