On first sight, it all seems to make sense and caters to your intuition. Increasing circulation = good; restricting nutrient flow & shutting down the signals between muscles and nerves = bad.
Don’t get me wrong, if you need to make something numb, ice is great. As Mr. Reinl points out, “Yes, (making something numb is good) if the short-term goal is pain control and the prevention of the body’s normal cellular and vascular response to injury.”
But I don’t have the knowledge to judge whether the information provided here is accurate.
Well, I hope it is not just to help selling this $650 Marc Pro device.
What’s the saying, “Extraordinary claims require extraordinary evidence”.
Here are some of the points mentioned:
- on Resting – you need a little bit of stress to increase circulation, immobilization reduces the lymphatic system’s effectiveness
- on Icing – causes a back flow creates more congestion (causes the fluid in the lymphatic vessels to backflow), no study says it works, shuts down the signal between the muscles and the nerves
- focus more on Compression instead, wrap it up instead to avoid swelling
I know there are a bunch of PTs and MDs reading this. Please, leave your thoughts in the comments.
Thanks to Edwin for bringing this to my attention.
Update: Justin chimes in on the discussion. After looking at the cited papers he says that it’s entirely inconclusive and that Kelly’s claims are premature.
In another post he explains how you should use icing.
Injury occurs. Ice it. Compress it. Elevate it. After day one, start figuring out how you can apply progressive stress via movement. After rehab, it is okay to ice. Otherwise, try to compress and elevate the injury as much as possible. Rinse and repeat, but ween off of the icing (since it will eventually not do much other than numb the pain after the early stages).
Update: One year later, here is a follow up from Kelly.
