“Coaches have used my “RICE” guideline for decades, but now it appears that both Ice and complete Rest may delay healing, instead of helping.” – Gabe Mirkin, MD, March 2014
In 1978, Gabe Mirkin, MD coined the term RICE. Health care practitioners to laypersons are quick to recognize RICE as the ‘gold standard’ treatment option following injury. Followers of my blog know my stance against ice and now there is support from the physician who coined the term. Yes, the very same physician, Dr. Gabe Mirkin, who coined RICE, is now taking a step back. I reached out to Dr. Mirkin and asked for permission to share his story. As you will read below in Dr. Mirkin’s full post, the lack of evidence for cryotherapy is something we must listen to.
This is a controversial topic. My blog Why Ice and Anti-inflammatory Medication is NOT the Answer sparked a lot of debate. I had nearly 30,000 page hits per day for several weeks. I recently received a tweet from a peer (@AlanMRussell) who attended a presentation by Cindy Trowbridge from the University of Texas-Arlington refuting many of my comments. The debate continues, but given the evidence – or lack thereof – I stand by my thoughts that ice does not facilitate tissue healing.
I recently had the pleasure of connecting with Nichan “Nick” Zourikian a physiotherapist and researcher at Sainte-Justine University Hospital Center in Quebec. Nick published a study with Angela Forsyth, DPT (Rush University Medical Center) that led to a unique, in-journal debate among experts. The original review article published in Haemophilia, challenged the effectiveness of ice (1). This led to a “Letter to the Editor” rebuttal published one year later (2), which led to a rebuttal to the rebuttal published in the same journal (3). Why is this such a hot topic? Nick summed it up perfectly in an email:
“There clearly exists a dogmatic polarization on the use of ice in our physiotherapist/athletic therapist communities! Old habits die hard. Many colleagues (even in our hemophilia community) still insist on using ice…despite the current scientific evidence available.” Nick is spot on, RICE is an old habit that is dying hard.
I have long said modalities are overused and exercise is under used. Ice: The Overused Modality was my first post to make this point. I have added several posts that demonstrate the need for exercise and the positive effect mechanical load has on tissue healing and repair. See my posts on Mechanotransduction, Achilles Tendinopathy and reversibility as these explain more.
The NATA’s position statement in August 2013 on management of ankle sprains would support my anti-ice case. The researchers for the NATA position statements take years to critically appraising data to make conclusions. They comb over all the data and rate evidence from best “A” to worst “C”. In this particular position statement cryotherapy was overall a C rating for evidence (4). The article says “Strong clinical evidence for advocating cryotherapy is limited”. The evidence that had the better ratings: functional rehabilitation, proprioception, balance, and range of motion (note: these are all tissue loading exercises) (4). What’s interesting is many of the readers to my blog are athletic trainers, physical therapists, and physiotherapists. Yet, they are the ones who think I am nuts. Your own organization has a comprehensive position statement that supports my thoughts. Am I that crazy?
I read a piece on Medscape the lead author of the NATA position statement, Thomas W. Kaminski, PhD, ATC, said that he believes that many practitioners are still following the prescription too closely (5). The article goes on to quote Dr. Kaminski: “I wish I could say that what we found is what is really being done in a clinical setting.” There is another quote: “Maybe our European colleagues know something we don’t”…”there is very little icing over there.” (5)
Despite the lack of evidence advocating the use of ice the debate continues. Peers continually challenge me and would like to see me hung, drawn, and quartered for suggesting no ice. ‘My gosh, you mean I shouldn’t take 30 ice bags out to the baseball field wrap shoulder and elbows? You’re insane!’ A shift in paradigmatic treatment is on the horizon. Exercise is heating up and ice is melting down. Below is the full article from Dr. Mirkin’s website, which will only fuel the end of the ice age.

by Gabe Mirkin, MD
When I wrote my best-selling Sportsmedicine Book in 1978, I coined the term RICE (Rest, Ice, Compression,Elevation) for the treatment of athletic injuries (Little Brown and Co., page 94). Ice has been a standard treatment for injuries and sore muscles because it helps to relieve pain caused by injured tissue. Coaches have used my “RICE” guideline for decades, but now it appears that both Ice and complete Rest may delay healing, instead of helping.
In a recent study, athletes were told to exercise so intensely that they developed severe muscle damage that caused extensive muscle soreness. Although cooling delayed swelling, it did not hasten recovery from this muscle damage (The American Journal of Sports Medicine, June 2013). A summary of 22 scientific articles found almost no evidence that ice and compression hastened healing over the use of compression alone, although ice plus exercise may marginally help to heal ankle sprains (The American Journal of Sports Medicine, January, 2004;32(1):251-261).
Healing Requires Inflammation
When you damage tissue through trauma or develop muscle soreness by exercising very intensely, you heal by using your immunity, the same biological mechanisms that you use to kill germs. This is called inflammation. When germs get into your body, your immunity sends cells and proteins into the infected area to kill the germs. When muscles and other tissues are damaged, your immunity sends the same inflammatory cells to the damaged tissue to promote healing. The response to both infection and tissue damage is the same. Inflammatory cells rush to injured tissue to start the healing process (Journal of American Academy of Orthopedic Surgeons, Vol 7, No 5, 1999). The inflammatory cells called macrophages release a hormone called Insulin-like growth Factor (IGF-1) into the damaged tissues, which helps muscles and other injured parts to heal. However, applying ice to reduce swelling actually delays healing by preventing the body from releasing IGF-1.
The authors of one study used two groups of mice, with one group genetically altered so they could not form the normally expected inflammatory response to injury. The other group was able to respond normally. The scientists then injected barium chloride into muscles to damage them. The muscles of the mice that could not form the expected immune response to injury did not heal, while mice with normal immunities healed quickly. The mice that healed had very large amounts of IGF-1 in their damaged muscles, while the mice that could not heal had almost no IGF-1. (Federation of American Societies for Experimental Biology, November 2010).
Ice Keeps Healing Cells from Entering Injured Tissue
Applying ice to injured tissue causes blood vessels near the injury to constrict and shut off the blood flow that brings in the healing cells of inflammation (Knee Surg Sports Traumatol Arthrosc, published online Feb 23, 2014). The blood vessels do not open again for many hours after the ice was applied. This decreased blood flow can cause the tissue to die from decreased blood flow and can even cause permanent nerve damage.
Anything That Reduces Inflammation Also Delays Healing
Anything that reduces your immune response will also delay muscle healing. Thus, healing is delayed by:
- cortisone-type drugs,
- almost all pain-relieving medicines, such as non-steroidal anti-inflammatory drugs like ibuprofen (Pharmaceuticals, 2010;3(5)),
- immune suppressants that are often used to treat arthritis, cancer or psoriasis,
- applying cold packs or ice, and
- anything else that blocks the immune response to injury.
Ice Also Reduces Strength, Speed, Endurance and Coordination
Ice is often used as short-term treatment to help injured athletes get back into a game. The cooling may help to decrease pain, but it interferes with the athlete’s strength, speed, endurance and coordination (Sports Med, Nov 28, 2011). In this review, a search of the medical literature found 35 studies on the effects of cooling . Most of the studies used cooling for more than 20 minutes, and most reported that immediately after cooling, there was a decrease in strength, speed, power and agility-based running. A short re-warming period returned the strength, speed and coordination. The authors recommend that if cooling is done at all to limit swelling, it should be done for less than five minutes, followed by progressive warming prior to returning to play.
If you are injured, stop exercising immediately. If the pain is severe, if you are unable to move or if you are confused or lose even momentary consciousness, you should be checked to see if you require emergency medical attention. Open wounds should be cleaned and checked. If possible, elevate the injured part to use gravity to help minimize swelling. A person experienced in treating sports injuries should determine that no bones are broken and that movement will not increase damage. If the injury is limited to muscles or other soft tissue, a doctor, trainer or coach may apply a compression bandage. Since applying ice to an injury has been shown to reduce pain, it is acceptable to cool an injured part for short periods soon after the injury occurs. You could apply the ice for up to 10 minutes, remove it for 20 minutes, and repeat the 10 minute application once or twice. There is no reason to apply ice more than six hours after you have injured yourself.
If the injury is severe, follow your doctor’s advice on rehabilitation. With minor injuries, you can usually begin rehabilitation the next day. You can move and use the injured part as long as the movement does not increase the pain and discomfort. Get back to your sport as soon as you can do so without pain.
I want to thank Dr. Mirkin for allowing me to share his article. I really appreciate his continued contributions to health and wellness.
