Knuckle cracking – A Model
Interestingly, a paper was recently published challenging what we had seen in our PLOS One study. It would seem reasonable that there would be others looking to crack the code on the sound source of a joint pop. It is such a common phenomenon. In their study, they used a mathematical model to simulate what they believe is going on inside a joint when it makes an audible release sound. You know, that cracking sound that chiropractors generate to help those with joint pain.
To take you back a bit on what all the fuss is about, it was a researcher by the name of Roston
