If you've been dealing with muscle or joint pain — from a sports injury, surgery, plantar fasciitis, or something like a bad back or sore knee — you've probably considered a TENS machine. They're sold at Chemist Warehouse, Kmart, and Priceline, they're affordable, and they've been around for decades.
But TENS isn't the only drug-free option available, and depending on what's causing your pain, it may not be the most effective one either.
This article explains how TENS machines work, what the research actually says about them, and introduces a newer therapy — available now in Australia and New Zealand — that clinical trials show outperforms TENS specifically for musculoskeletal and post-surgical pain.
How Does a TENS Machine Work?
TENS stands for Transcutaneous Electrical Nerve Stimulation. It works by sending low-voltage electrical pulses through adhesive electrode pads placed on the skin. These pulses interfere with pain signals travelling to the brain — a process based on gate control theory, where competing sensory signals reduce the perception of pain.
TENS machines are commonly used for back pain, arthritis, period pain, and general muscle soreness. They require either an electrical outlet or a charged battery, and the adhesive pads need to be replaced regularly.
TENS has a reasonable body of research behind it, particularly for chronic pain. It works for a lot of people, and there's nothing wrong with using one. But for muscle injuries, joint pain, and post-surgical recovery specifically, the research tells an interesting story.
What Is Vibration Therapy for Muscle Pain — and How Is It Different?
Vibration therapy for muscle pain works on the same gate control principle as TENS — but instead of electrical stimulation, it uses mechanical stimulation delivered at a specific high frequency directly to the affected area.
The technology used in VibraCool devices is called M-Stim® — short for Mechanical Stimulation. It was developed by Pain Care Labs, a US-based medical device company that has been researching non-drug pain relief since 2006. Their devices are used in hospitals, physiotherapy clinics, and sports recovery settings worldwide.
Alongside the vibration, VibraCool uses cold or heat therapy simultaneously. The cold reduces inflammation and activates a second pain-relief mechanism — called Descending Noxious Inhibitory Control — where intense cold raises the body's overall pain threshold. The heat option is particularly useful for muscle spasms and chronic stiffness.
The combination of vibration and thermal therapy is what sets it apart from TENS, which uses only electrical stimulation.
What Does the Research Show: Vibration Therapy vs TENS?
A crossover clinical trial presented at the American Academy of Physical Medicine and Rehabilitation in 2019 compared high-frequency vibration therapy directly against TENS for musculoskeletal pain. The results were clear.
Mean pain relief with vibration therapy was 3.60, compared to 1.40 with TENS — a statistically significant difference (P<0.0001). Vibration therapy produced the strongest results for spine pain, injury-related pain, and post-surgical pain. performed better for osteoarthritis.

The takeaway is straightforward: if you're recovering from an injury or surgery, or dealing with muscle and joint pain, vibration therapy has stronger clinical support than TENS for those specific situations. For osteoarthritis or chronic nerve pain, TENS remains a reasonable option.
What Conditions Does Vibration Therapy Help With?
Plantar Fasciitis and Heel Pain
Plantar fasciitis is one of the most common causes of heel pain in Australia, affecting an estimated 900,000 Australians. It involves inflammation of the tissue band running along the base of the foot and is notoriously slow to resolve. Ice is a standard recommendation, but combining it with high-frequency vibration at the arch increases blood flow to the area, which supports healing alongside reducing pain. VibraCool Plantar is specifically designed for this, with the strap and ice packs positioned precisely at the arch of the foot.
Knee and Ankle Pain
For knee pain — whether from post-surgical recovery, ACL injury, IT band syndrome, patellofemoral pain, or general joint inflammation — vibration therapy applied to the area can reduce pain and support recovery. One patient reported sleeping through the night for the first time after using VibraCool for arthritis affecting both the knee and foot. VibraCool Extended is designed for the knee and ankle, with a 28-inch compression strap that fits larger joints comfortably.
Back, Shoulder, Neck, and Hip Pain
A 2023 Phase I clinical pilot study published in Frontiers in Pain Research found that multi-modal mechanical stimulation reduced both acute and chronic low back pain, with results independent of patient age or how long the pain had been present. VibraCool Flex covers the back, shoulder, neck, and hip — and comes with both an ice pack and a heat pack, since heat is often more helpful than cold for muscle spasm and chronic stiffness in these areas.
Elbow and Wrist Pain
For tennis elbow, golfer's elbow, carpal tunnel discomfort, and post-surgical wrist or elbow recovery, VibraCool EasyFit allows one-handed application via a D-ring strap. A 2017 study found that vibration therapy after distal radius (wrist) fracture surgery was an effective management strategy for both pain relief and hand function, with improvements persisting for up to two months.
Post-Surgery Recovery at Home
After surgery, having a way to manage pain at home without relying solely on medication is something most patients want. A 2015 study in the American Journal of Sports Medicine found that five minutes of daily vibration after arthroscopic rotator cuff repair provided meaningful pain relief at six weeks compared to placebo. VibraCool can be placed on the skin above dressings — it doesn't need direct contact with the wound site.
"I used VibraCool and for the first day, I didn't need my pain pills after knee surgery. Wish I had discovered this product years ago!"
— VibraCool customer
"Not gonna lie, was skeptical. But this thing is the only relief for my fibromyalgia pain. I don't like the feeling of ice on my skin, but the vibration helps with both reducing pain and making the ice feel less cold. 100% would recommend to anyone with chronic pain."
— VibraCool Extended customer
Is VibraCool Safe to Use?
Yes. VibraCool is TGA-approved in Australia and MedSafe-approved in New Zealand. It is also approved for use with pacemakers — something that TENS machines are not, as electrical stimulation can interfere with pacemaker function. It contains no medication, no chemicals, and is battery operated with no cords or outlets required.
It is not recommended for use directly over broken skin, open wounds, or areas with known circulatory conditions. As with any pain management device, check with your doctor or physiotherapist if you are unsure whether it's appropriate for your specific situation.
