There are several common areas you should avoid placing electrodes. These guidelines can help reduce risk and improve comfort:

• Around the eyes, mouth, or over the front of the neck (carotid sinus).
• Directly over the chest where a pacemaker or implanted device might be located, unless cleared by a clinician.
• On broken, irritated, or infected skin, or over areas with reduced sensation.
• Across the head, throat, or over the heart.

Always follow the device manual for approved placements and consult a healthcare professional for personalized guidance.

Think about how you plan to use the device and what features matter most to you:

• Mobility: Wireless units offer more freedom of movement and fewer tangles; wired units can be simpler and sometimes less expensive.
• Controls: Wireless models often include remotes or apps for presets; wired units typically have on-device controls.
• Channels and pads: Check how many channels and pads the unit supports‚Äîmore channels let you treat multiple areas at once.
• Battery and maintenance: Look for rechargeable batteries, pad compatibility, and how easy replacements are to find on Walmart.

Compare product specs, read customer reviews, and use Walmart's return policy if the unit doesn't meet your needs.

Proper care can extend pad life and keep treatments hygienic. Try these practical steps:

• Clean and dry skin before each session to remove oils and lotions so pads adhere better.
• After use, place pads back on their protective plastic backing and store them in a cool, dry place away from direct sunlight.
• Avoid using alcohol or harsh cleaners on the gel surface‚Äîcheck the manufacturer‚Äôs care instructions for your pads.
• Replace pads when they lose stickiness or the gel is damaged; Walmart carries replacement pads and accessories.

Following the manual helps maintain performance; results can vary by pad type and usage.

They use electrical pulses but aim for different effects:

• TENS (Transcutaneous Electrical Nerve Stimulation): Generally delivers pulses intended to interact with sensory nerves. People use it for symptom relief and to change how nerves signal.
• EMS (Electrical Muscle Stimulation): Typically produces stronger pulses that cause muscle contractions and are often used for muscle activation or rehabilitation.
• Device features: Some units offer both TENS and EMS modes‚Äîcheck the mode descriptions and intensity ranges on product pages.

If you're unsure which is appropriate for your needs, consult a healthcare professional. Use Walmart’s product info and reviews to compare features and compatibility.
