About 40 years ago, Dr. Gabe Mirkin coined the acronym RICE – Rest, Ice, Compression, Elevation – which has been the standard treatment protocol for most athletic injuries ever since.
Recently, however, a slew of studies have begun to show that icing actually delays healing. (For some good examples, see this one and this one.) The studies are persuasive; so much so that even Dr. Mirkin has changed his mind, updating RICE to the new (albeit much less pronounceable) MCE: Movement, Compression, Elevation.
In short, while inflammation was initially considered to be a source of damage (hence icing, which reduces that inflammation), scientists increasingly understand that inflammation is actually a key part of the healing process, with inflammatory cells called macrophages releasing hormones into the damaged tissue to help with repair. (Here’s a recent study on that process.)
Eagle-eyed readers will note that Mirkin isn’t just dropping icing, he’s also swapping rest for movement (or, more specifically, for “move safely when you can as much as you can”). Continuing to gently move an injured joint or muscle promotes the flow of fluid into and out of the area around the injury (which allows those macrophages to get in when they need to work, and to depart once they’re done), and prevents the injured tissues from wasting as they would with complete rest.
So throw out that stack of old ice packs in your freezer, and start thinking of creative ways to say “MCE” out loud.
