Do You Crack Your Knuckles?

Although studies have been made on knuckle cracking, there is no definitive answer on whether or not it is bad for your knuckles. A 1990 study indicates that people who crack their knuckles are more likely to experience hand swelling and a lighter grip. However, the study does not provide direct evidence correlating the two and is inconclusive. A more recent study was performed by a hand surgeon and a radiologist at UC Davis Medical Center which investigated the hands of people who crack their knuckles versus those who did not crack their knuckles. There was nothing to indicate that damage was done by cracking your knuckles, including swelling of the hands and waning of the grip. Actually, they determined that range of motion increased after the knuckles were cracked. Even though it appears to be good to crack your knuckles, the two doctors admitted that an even broader study could be made contradicting their findings.

What does happen when you crack your knuckles?

It is commonly believed that gas bubbles are released as the joint is extended. However, it is now believed that joint cracking is related to cavity formation as opposed to the popping of gas bubbles. One study collected real-time footage through the use of MRI. The results of the imaging tests showed that the sound was produced at the moment a cavity was created in the joint at the point of joint separation. The cavity remains visible even after the sound has been made.

Does knuckle cracking cause arthritis?

This is an old wives tale. It has been speculated that grandmothers, aunts, and mothers over time reacted to the noise with disdain. In order to discourage knuckle cracking, these women spun these tales. There is no evidence to substantiate these claims.
