For physiotherapists and sports medicine clinics
VibraCool for physiotherapists: drug-free pain relief your patients can use between sessions
VibraCool uses M-Stim, a patented mechanical stimulation technology, with ice or heat. Your patients wear it in your treatment room and at home, so the relief continues between sessions and they come back ready to work. In a crossover trial, patients rated it up to 3.4 times more effective than TENS.
The technology
What is M-Stim?
M-Stim is short for mechanical stimulation. It is the patented technology behind VibraCool, developed by Pain Care Labs with NIH research funding. Instead of electrical current, M-Stim uses fast vibration to switch on the nerves that block pain.
Deep touch receptors called Pacinian corpuscles respond best to fast vibration. Research found they drive about 90% of the pain relief vibration gives (Hollins, 2017). VibraCool runs at 150 to 200 Hz, the range these receptors respond to. Their signals travel on large, fast A-beta fibres and crowd out pain signals at the spinal cord. Above 150 Hz, vibration also increases local blood flow.
How VibraCool eases pain
What is the difference between M-Stim and E-Stim?
| M-Stim (VibraCool) | E-Stim (TENS) | |
|---|---|---|
| How it works | Vibration at 150 to 200 Hz | Electrical current |
| Nerves it targets | Deep Pacinian receptors | Light touch receptors |
| How it feels | Relief on contact | Tingle or muscle twitch |
| Cold or heat | Built in | None |
| Pacemakers | Safe to use | Check with a doctor first |
| Ongoing costs | None, reusable | Replacement electrodes |
Is VibraCool better than TENS for patients who already own one?
In a crossover trial, the same patients rated VibraCool up to 3.4 times more effective than TENS. Many of your patients arrive with a TENS unit that stopped helping, and they are a good group to start with. See the full vibration therapy vs TENS comparison.
What it is
What is VibraCool?
VibraCool is a wearable pain relief device that combines M-Stim vibration with ice or heat. It was invented by Dr Amy Baxter MD, an emergency physician and pain researcher, and is made by Pain Care Labs, the team behind Buzzy. Buzzy4Shots is the official distributor in Australia and New Zealand.
If you know Buzzy from hospitals or vaccination clinics, this is the same physiology applied to muscle and joint pain. It sits alongside your treatment, not in place of it. You keep your assessment, loading and hands-on work.

The VibraCool advantage
Proven
Patented M-Stim technology gave up to 3.4 times the pain relief of TENS in a crossover trial.
Ice
Ice blocks pain and reduces inflammation.
Vibration
Vibration vasodilates to increase blood flow, mechanically separates muscle fibres to reduce DOMS, and reduces spasm.
Portable
Lightweight and portable, VibraCool makes compliance easy. It can be used for rehabilitation exercises and pain relief in the clinic, on the field, at work or at home.
The gap between sessions
Pain doesn't stop when the session ends
Between sessions
At home, your patients manage pain with ice, rest or medication until their next appointment. A flare-up can undo the progress you made together.
After surgery
Opioids are often the default. Australia's opioid stewardship standard asks clinicians to discuss non-drug options too.
In the session
Sore patients guard and tire quickly, so loading and hands-on work take longer than they need to.
VibraCool gives your patients a drug-free option that is simple enough to use every day.
Why use it in your clinic
How does VibraCool help your sessions go further?
Less pain means your patients can do more in the time you have with them.

Cleared for physio use
VibraCool is FDA cleared for use before or during physical therapy, for trigger point pain, restricted motion and muscle tension.
Easier on your hands
In a 2023 study, VibraCool was as effective as manual compression for trigger point pain, with less strain on your thumbs.
Hands-free
It straps on, so it keeps working while you treat another area or supervise exercises.
A plan for home
Patients take the same protocol home. Stock kits in your clinic so they leave with relief for between visits.
Wider vibration research also shows better ankle and hamstring flexibility after 10 minutes of local vibration, and lower muscle soreness 24 to 72 hours after exercise. These studies used local vibration, not VibraCool itself.
The evidence
What does the research show about VibraCool?
For your clinic
What is VibraCool Pro?
VibraCool Pro is the clinic range. The motor units are built for daily use across many patients and wipe clean between them. There are three models, each suited to a different part of your caseload.

In the treatment room
VibraCool Pro Healthcare
One motor unit, five single-chamber ice packs and two hands-free straps.
- Warm up muscles for 5 to 10 minutes before treatment, without ice
- Settle pain after treatment with ice, 20 minutes
- Pain Care Labs suggests using it any time you would use E-stim in clinic

Knee, ankle and leg
VibraCool Pro Lower Extremity
Two motor units, a 30-inch neoprene compression cuff, a four-chamber ice pack and a hot pack.
- Knee and ankle pain, and muscle pain after lower-limb surgery
- Two units sit on opposite sides of the limb to cover more of the painful area
- After surgery, it sits just above the bandage

Elbow, wrist and arm
VibraCool Pro Upper Extremity
Two motor units, a 22-inch neoprene cuff with D-ring, a two-chamber ice pack and a hot pack.
- Tennis and golfer's elbow, and tendinitis around the elbow and forearm
- Muscle pain after upper-limb surgery
- The D-ring lets you tighten it snugly on the arm
Take-home models
Which conditions can physiotherapists use VibraCool for?
Four take-home models, each shaped for a different body area. Stock them in your clinic so patients keep the same routine at home.

Knee and ankle
- Knee pain and ACL recovery
- Meniscal injury
- Runner's knee (patellofemoral pain)
- IT band pain
- Ankle pain and sprains

Elbow and wrist
- Tennis and golfer's elbow

Questions from physios
Common questions about vibration therapy in physiotherapy
In physiotherapy, localised vibration is mainly used for pain relief and muscle soreness, so patients can move and load with less pain. VibraCool straps onto the painful area. Physios use it for knee, elbow, shoulder, neck, back, hip, ankle and heel pain.
E-Stim, such as TENS, uses electrical current on the skin. M-Stim uses mechanical vibration at a set frequency, with no current. VibraCool's M-Stim runs at 150 to 200 Hz, which targets deep Pacinian touch receptors. It adds ice or heat, needs no electrodes and is safe with pacemakers.
VibraCool Pro is the clinic range of VibraCool. Pro Healthcare is a single unit for the treatment room. Pro Lower Extremity and Pro Upper Extremity each have two motor units on a compression cuff for the leg or arm, with ice and hot packs. The motor units wipe clean between patients.
TENS helps some patients. In a trial where the same patients tried both, they rated VibraCool up to 3.4 times more effective. VibraCool uses vibration instead of electrical current, so there are no pads to place or replace. Patients who stopped getting relief from TENS are a good group to start with. See the full vibration therapy vs TENS comparison.
Exercise and graded loading, manual therapy, education, heat, cold, bracing, TENS and vibration. Australia's Opioid Analgesic Stewardship in Acute Pain Clinical Care Standard asks clinicians to discuss these non-drug options with patients. VibraCool combines two of them, vibration and cold, in one device patients can use at home.
TENS units, heat and cold packs, ultrasound, shockwave and massage devices are the most common. Wearable vibration devices such as VibraCool are a newer option, used in the treatment room and sold to patients for home use. In Australia and New Zealand, clinics order VibraCool from Buzzy4Shots, the official distributor, through the clinician order form.
For pain relief, yes. A 2025 review in the International Journal of Sports Physical Therapy found the strongest evidence for vibration in pain relief, flexibility and muscle soreness. A 2023 NIH-funded study of VibraCool-style vibration found a 57% average drop in pain.
No. Vibration plates are for strength and balance training, and massage guns use heavy, slower strokes. VibraCool is a small wearable strapped over the painful area, with light, fast vibration plus cold. Most massagers run well below 150 Hz, the level Pain Care Labs says is needed to increase blood flow.
Yes. There is no electrical current, only vibration with cold or heat.
Use vibration on its own, which Pain Care Labs says gives more than 40% of the pain relief. Or swap the ice pack for the heat pack.
VibraCool adds high-frequency vibration to cold, and it is small enough to wear during exercise. Ice machines cover a larger area, which some patients prefer for a swollen knee in the first days after surgery. Many patients use both.
Pain Care Labs suggests 5 to 10 minutes of vibration on its own to warm up muscles before treatment or exercise. Clinicians also use it before taping, kinesiology tape or instrument-assisted soft tissue work. Patients can wear it during rehab exercises. After exercise, use vibration with the ice pack, or the heat pack, for 20 minutes.
Do not use it over broken skin, a rash or a burn, or when a patient has calf pain you cannot explain. Skip the ice pack for patients who are sensitive to cold, such as with Raynaud's, CRPS or sickle cell disease. Use vibration on its own or the heat pack instead.
Pain Care Labs suggests 20 minutes, 2 to 3 times a day. For acute injury and after surgery, use ice and vibration 2 to 3 times a day for at least 5 days. For tendinitis and plantar fasciitis, use it 2 to 3 times a day for 10 days, then daily. For persistent pain or spasm, swap the ice pack for the heat pack.
Place the ice pack on or just above the point of pain, with the unit over it, and strap it in place. For tennis elbow, that is the outer elbow just below the joint. After surgery, place it on the skin just above the dressing, never over the incision. The step-by-step guide is on how to use VibraCool.
