While ice decreases pain and inflammation, it can also decrease blood flow and stiffen muscles.  Adding massage improves blood flow, enhancing the removal of lactic acid, cytokines and injured tissue, while vibrational massage reduces pain and loosens stiff muscles.  FDA cleared VibraCool™ puts cold and vibration together for the first time! 

Created by a pain management physician, VibraCool™ Massaging Ice Therapy is a reusable over the counter pain device. From aches to injuries to athletic training,  VibraCool™ provides alternative drug-free pain relief. VibraCool™ overwhelms the pain nerves with neutral sensations of cold and vibration, with a strap that keeps the unit in place even with activity. For aches and injuries, place VibraCool™ directly on the site for 10 - 20 minutes with both ice and vibration activated for relief on contact.

Independently verified research shows VibraCool works!

In a study comparing the effect of vibration therapy and massage in prevention of Delayed Onset Muscle Soreness, vibration was superior for clinical early reduction of pain.

Over 5,000 hospitals and clinics and more than 50,000 users have adopted our unique Cool-Pulse™ technology with VibraCool™ or Buzzy®.  Buzzy®, our flagship pain relief device, uses vibration and ice to decrease pain from injections and needle sticks. Buzzy® was a Medical Design Excellence Awards recipient and Georgia Bio Most Innovative Company recipient in 2014.  


how it works - Pain relief physiology


The gate control mechanism is the basis for VibraCool™.  "Gate control” is the term used to describe pain relief by confusing your body's own nerves and distracting away from the pain.  Nerve sensations of temperature (c fibers) or vibration (a beta fibers) combine in the spine to send one message to the brain. Hyperstimulating cold and vibration "shuts the gate" on the small, fast a delta sharp pain sensations, so the brain only perceives cold and motion.


Just as running a burn under cold water stops the burn, stimulating cold receptors can dull pain.  Ice frozen solid also induces Descending Noxious Inhibitory Control, or DNIC, reducing pain by taking up bandwidth in the pain-processing area of the brain and sending inhibitory signals down to block pain throughout the body.

Cold + Vibration research

Cold and vibration together have been extensively studied for needle pain.  If you can numb needles, aches are easy.  Bibliography found here for Buzzy needle procedure research.



Vibration for Athletic Training and Rehabilitation

A Randomized, Double-Blinded, Placebo-Controlled Clinical Trial Evaluating the Effectiveness of Daily Vibration After Arthroscopic Rotator Cuff Repair.  Lam PH, Hansen K, et al.  Am J Sports Med 2015 43: 2774.  5 minutes of vibration was applied daily after arthroscopic rotator cuff repair for 6 months.  Vibration did provide acute pain relief at 6 weeks after surgery (visual analog scale [VAS] score, 2.24 6 0.29 cm) compared with placebo (VAS score, 3.67 6 0.48 cm) (P\.003).

Improvement of stance control and muscle performance induced by focal muscle vibration in young-elderly women: a randomized controlled trial.  Filippi GM, Brunetti O, Botti FM.  Arch Phys Med Rehabil.  2009 Dec(12):2019-25 .  60 sedentary women underwent repeated muscle vibration in three 10-minute sessions a day for 3 consecutive days applied to voluntary contracted quadriceps or relaxed quadriceps. A third group received placebo stimulation (non-vibrated group).  Twenty-four hours after the end of the complete series of applications, the area of sway of the center of pressure decreased significantly by approximately 20%, vertical jump increased by approximately 55%, and leg power increased by approximately 35%. These effects were maintained for at least 90 days after treatment.

­Focal vibration of quadriceps muscle enhances leg power and decreases knee joint laxity in female volleyball players. Brunetti O, Botti FM et al.  J Sports Med Phys Fitness. 2012 Dec;52(6):596-605.  Eighteen voluntary volleyball athletes, belonging to the same senior regional level team (age=22.7 ± 3 years, height=180.3 ± 5 cm, mass= 64 ± 4 kg) were assigned to three groups (N.=6) for vibration on contracted quadriceps (VC), vibration on relaxed muscle (VR), and sham vibration (NV).  Conclusion: Combined bilateral voluntary contraction and vibration of the quadriceps muscles is a short-lasting, non-invasive technique that can significantly and persistently improve muscle performance and knee laxity in volleyball women players.

Vibration for Healing

The acute effects of local vibration therapy on ankle sprain and hamstring strain injuries.  Peer KS, Barkley JE, Knapp DM Phys Sports Med. 2009;37(4):31-38 “Relative to the post-control condition, local vibration for 10 minutes significantly (P < 0.03 for all) increased ankle dorsiflexion and eversion and hamstring flexibility, and significantly (P <or= 0.05) decreased perceived ankle and hamstring stiffness.”

Delayed Onset Muscle Soreness

To Compare the Effect of Vibration Therapy and Massage in Prevention of Delayed Onset Muscle Soreness (DOMS).  Imtiyaz S, Vegar Z, Shareef MY.  J Clin Diagn Res.  2014 Jan;8(1):133-6.  45 nonathletic women were randomized to 15 minutes of massage, 5 minutes of focal vibration, or no intervention prior to exercise. Vibration therapy and massage are equally effective in prevention of DOMS. Massage is effective in restoration of concentric strength (1 RM). Yet vibration therapy shows clinically early reduction of pain and is effective in decreasing the level of LDH in 48 hours post exercise periods.

Vibration Therapy in Management of Delayed Onset Muscle Soreness (DOMS).  Vegar Z. Imtiyaz S.  J Clin Diagn Res. 2014 Jun;8(6)LE01-4.  “Vibration has shown effectiveness in flexibility and explosive power. Vibration can apply either local area or whole body vibration. Vibration therapy improves muscular strength, power development, kinesthetic awareness, decreased muscle sore, increased range of motion, and increased blood flow under the skin. VT was effective for reduction of DOMS and regaining full ROM. Application of whole body vibration therapy in post-exercise demonstrates less pressure pain threshold, muscle soreness along with less reduction maximal isometric and isokinetic voluntary strength and lower creatine kinase levels in the blood.”

Effects of vibratory stimulations on maximal voluntary isometric contraction from delayed onset muscle soreness.  Koh HW, Cho SH et al.   J Phys Ther Sci. 2013 Sep;25(9):1093-5.  60 Healthy adults participated, with DOMS induced in the musculus extensor carpi radialis longus.  Ultrasound or vibratory stimulation for 10 minutes or control was used.  Vibration had a positive effect on recovery of muscle function from DOMS compared to the control group, while ultrasound did not.
