“You’re going to get arthritis!”
You’ve heard it. Is it an urban myth, or is cracking your knuckles actually good for you? Well according to a study completed by UC Davis radiologist, Dr. Robert Boutin – it might be! As described in this CNN article:
The idea was simple: Gather a bunch of knuckle-crackers (Johnson among them) and have them do their thing under ultrasound to see what was really going on inside the joint. Then examine the knuckles pre- and post-crack, along with the knuckles of a group of non-crackers, to look for problems, including hand swelling and waning grip strength.
And what did they find?!
The knuckle-crackers didn’t have any hand problems. In fact, after someone cracked a knuckle, it had an increased range of motion compared with knuckles they hadn’t cracked.
My mother has long told me that cracking my knuckles is an awful habit…well take that, Mom!
