When it comes to easing pain or speeding up recovery after a workout, there’s a good chance you’ve come across TENS machines and EMS machines. While both are types of portable therapy devices that use electrical stimulation, they serve different purposes. So, which one should you choose?

Let’s break it down.

Understanding TENS Therapy

What is TENS?

TENS, short for Transcutaneous Electrical Nerve Stimulation, is a drug-free, non-invasive way to help manage pain. It involves a small device—either handheld or tabletop—that’s connected to your body via thin wires and sticky electrode pads.

You place these pads directly on your skin, near the area where you're feeling pain. Once the device is turned on, it sends gentle, low-voltage electrical pulses through the skin to stimulate your nerves.

Don’t worry—it doesn’t hurt. Most people just feel a slight tingling or a warm buzz where the pads are placed. You can easily adjust the intensity and frequency to what feels right for you.

Just keep in mind—TENS doesn’t heal injuries. It won’t fix the root cause of your pain, but it does do a great job of reducing pain signals temporarily, making it easier to move, work, or just get on with your day.

How TENS Devices Work

A  nerve stimulation device sends low-voltage electrical pulses via electrode pads placed on the skin near the pain point. These pulses:

• Block pain signals from reaching the brain
  
• Stimulate the release of endorphins (your body’s natural painkillers)
  
  

Each session usually runs for about 15 to 40 minutes, and the relief often kicks in during or shortly after the session. It’s a great option if you're looking for something quick and easy to help ease discomfort throughout the day.

How TENS works makes it ideal for conditions like arthritis, fibromyalgia, back pain, and even period pain relief.

Understanding EMS Therapy

What is EMS?

Short for Electronic Muscle Stimulation, EMS is a popular tool in both physical therapy and fitness training. At a glance, it looks a lot like TENS—they both use small devices connected to electrode pads that stick to your skin. But the purpose is quite different.

With EMS, the electrodes are placed directly on specific muscle groups, not just areas of pain. For example, it’s often used on the quads after knee surgery to help rebuild strength and prevent muscle wastage.

Once switched on, the EMS machine sends electrical impulses that cause your muscles to contract, just like they would during a workout. These contractions can be quick and repetitive, or they can hold for longer stretches depending on your settings.

It’s basically like giving your muscles a workout without hitting the gym. Pretty handy, right? Especially if you're recovering from injury, dealing with limited mobility, or looking to maintain strength during rehab.

How EMS Devices Work

An EMS machine sends stronger electrical impulses than a TENS device. These pulses cause the muscles to contract, mimicking the action that occurs during physical activity. How EMS works helps activate muscles, making it ideal for:

• Muscle rehabilitation
  
  
• Post-workout recovery
  
  
• Improving muscle tone
  
  
• Preventing muscle atrophy in inactive individuals

Key Differences Between TENS and EMS

Purpose and Application

TENS and EMS units may look similar at first glance, but they serve very different purposes and are designed to target different areas. TENS is primarily used for pain relief therapy and works by targeting the nerves with gentle, lower-frequency pulses. This makes it ideal for conditions like chronic pain, arthritis, and post-op recovery, as it helps alleviate discomfort through gentle nerve stimulation that may cause mild muscle contractions

On the other hand, EMS focuses on muscle stimulation and recovery, delivering stronger pulses that trigger visible muscle movement. EMS is perfect for muscle strengthening, injury rehab, and athletic recovery, as it helps activate and rebuild muscles. So, while both machines use electrical impulses, they’re designed to deliver very different results.

Electrical Impulse Characteristics

While TENS and EMS devices might appear similar, their electrical impulses are quite different in both intensity and effect.TENS delivers gentle, low-frequency pulses aimed at the nerves, providing effective pain relief with minimal muscle contractions. On the other hand, EMS sends stronger impulses that actively stimulate muscle contractions, making it ideal for strengthening muscles and aiding recovery. Despite their similar appearance, these devices are designed to achieve distinct outcomes, with TENS focused on pain relief and EMS on muscle recovery.

Which Device Is Right for You? Enjoy TENS + EMS Benefits in One with PainPod — The Best of Both Worlds.

It depends on your goal. TENS and EMS units are designed for different purposes, so choosing the right one depends on what you're looking to treat. If you're aiming to boost recovery and improve muscle conditioning, EMS might be the way to go. But if you're dealing with back pain and need relief, TENS is probably a better option for you.

Choosing TENS for Pain Relief

If you're struggling with chronic pain—whether it’s from an old injury, surgery, or a condition like endometriosis—TENS therapy can provide fast, soothing relief without the need for medication.

It’s especially effective for conditions like:

• Back and neck pain
  
  
• Sciatica
  
  
• Joint discomfort
  
  
• Period pain

For something compact yet powerful, give the PainPod M a try. It’s a portable unit that delivers effective pain relief with advanced TENS technology, plus a very gentle EMS mode that’s often imperceptible, making it ideal for those who want the benefits of treatment without the typical sensations.

Choosing EMS for Muscle Stimulation

Recovering from a sports injury or surgery, or dealing with limited mobility? An EMS machine could be the solution. Electrical Muscle Stimulation (EMS) uses targeted electrical impulses to activate muscles, helping reduce atrophy, improve circulation, and support your body's natural healing. It's especially useful when muscles aren’t being used due to injury or recovery.

EMS can complement physiotherapy by strengthening weakened muscles and speeding up recovery. Plus, it allows you to engage specific muscles without stressing joints or inflamed areas.

Looking for something more powerful? The PainPod 3  is a professional-grade device used by physios and athletes across Australia. It’s designed for deep muscle work, post-injury support, and conditioning.

Pro tip: Start with a lower intensity and gradually increase. If unsure about how EMS fits into your routine, consult with your physio or health expert.

Frequently Asked Questions

Can I use TENS and EMS together?

Yes, you can. Some advanced devices—like the PainPod 3—are built to support both TENS and EMS modes, meaning you can switch between them depending on your specific needs. Whether you’re easing chronic pain or working on muscle recovery, it’s convenient to have both options in one portable therapy device. Just be sure to follow usage guidelines and give your body time to respond.

Is EMS Suitable for Daily Use? 

In general, EMS therapy is well-tolerated for daily use, especially when sessions are kept short. It’s widely used by athletes, physiotherapists, and people recovering from muscle injuries or surgery. That being said, it’s important to always follow the manufacturer's guidelines for proper use. If you have any concerns—whether you’re managing a medical condition, pregnant, or recovering from surgery—it’s a good idea to consult with your GP, physiotherapist, or other health professionals before starting or continuing daily EMS use. 

What’s better for period cramps: TENS or EMS?

For period pain, TENS therapy is the clear winner. It works by gently stimulating the nerves to block pain signals and release natural pain-relieving endorphins. It’s drug-free, non-invasive, and many users find it works within minutes. EMS, on the other hand, is designed more for muscle contraction than pain blocking, so it’s not the best fit for menstrual cramps.

Many of our customers use the PainPod M or PainPod 3 for discreet, on-the-go period pain relief—whether they’re at work, out and about, or relaxing at home.

Do I need a prescription to buy a TENS or EMS machine?

Nope—there’s no prescription needed to purchase a TENS machine or EMS device in Australia. All of our period pain relief devices are available directly through our website, so you can shop online at your own pace.

However, if you're treating a specific health issue—especially anything related to nerves, muscles, or post-surgery rehab—it’s always a good idea to speak with your doctor, physiotherapist, or healthcare provider before starting any new therapy.
