Common questions

Is this the same as a TENS unit?

No. TENS stimulates sensory nerves, which can mask pain while the device is on. ALIV uses NMES, which stimulates motor nerves to make muscles contract. You should feel a rhythmic muscle contraction, not just a surface buzz.

I've tried everything. Why would this be different?

Most treatments target pain signals, inflammation or structure. ALIV is built around a different idea: chronic pain can cause the deep muscles around a joint to stop firing properly, and NMES is designed to activate them again. It isn't right for everyone, and results vary. That's why there's a 90-day guarantee.

How long is a session, and when might I notice something?

Each session is 15 minutes, and the device shuts off automatically. Some people notice a difference within the first couple of weeks of regular use, others take longer, and some don't respond. Use it consistently for the full 90 days before deciding.

Is it safe? Does it hurt?

You'll feel a pulsing sensation and your muscles contracting. It should be firm but not painful, and you set the intensity, starting low. Don't use ALIV if you have a pacemaker or other implanted electrical device, or if you're pregnant. Talk to your doctor first if you've had recent surgery or have any serious medical condition.

What if it doesn't work for me?

Return it within 90 days for a full refund. No restocking fee, no subscription, no hidden charges.

Is it FSA/HSA eligible?

Eligibility depends on your plan, and many plans require a letter of medical necessity. Check with your plan administrator before you buy.

How long do the gel pads last?

Typically around 20–30 uses, depending on your skin and how you care for them. Replacement pads are $24.95 (small, 2-head) and $29.95 (large, 4-head).

How do I charge it?

ALIV is rechargeable and comes with a charger. Full charging instructions are included in the box.

How ALIV works

Three steps, about 15 minutes, no clinic visit.

Place

Put the wireless patch over the area. Use the large 4-head patch for your back and the small 2-head patch for your knee.

Set

Pick a mode and start at a low intensity. Raise it until you feel a comfortable muscle contraction.

Relax

Sit or lie down for 15 minutes. The device turns itself off.

Simple to use. No cords. No clinic.

TENS vs. NMES

Both use electrical stimulation, but they work on different nerves.

	Typical TENS unit	ALIV (NMES)
Targets	Sensory nerves	Motor nerves
Designed to	Mask pain while worn	Activate muscles
What you feel	Tingling or buzzing	Rhythmic muscle contraction
Cords	Usually yes	None, fully wireless

Where NMES comes from

The technology isn't new. This describes NMES in general, not ALIV specifically.

◆

Clinical rehab. Therapists use NMES to help rebuild muscle after injury and surgery.

◆

Space research. In 2025, astronauts on the ISS tested electrical muscle stimulation to counter muscle loss in space.

◆

ESA experiment. The European Space Agency's EasyMotion-2 is testing it on the neck, back, shoulders, thighs and knees.

◆

Sports medicine. Athletes have used electrical muscle stimulation in training and recovery for decades.

Who ALIV is for

Adults with ongoing muscle-related back or knee discomfort who want a drug-free option to try at home.

→

Chronic lower back pain that keeps coming back after other treatments

→

Knee discomfort from everyday wear, activity or aging

→

Anyone who wants an at-home option instead of another trip to the clinic

→

Gift buyers helping a parent or spouse. Setup takes three steps.

Not for people with a pacemaker or other implanted electrical device, or who are pregnant. Ask your doctor first if you've had recent surgery.

What to expect

Everyone responds differently. Here's a realistic picture.

Your first session

You'll feel your muscles contract in a steady rhythm. Start low and build up. It shouldn't hurt.

The first few weeks

Use ALIV regularly, ideally daily. Some people notice changes in stiffness, movement or sleep during this time.

Up to 90 days

Give it the full 90 days. If you don't feel it's helping, send it back for a full refund.

Try it for 90 days. Keep it only if it helps.

You're covered by a full refund, with no subscription and no hidden charges.
