Knuckle cracking meaning

Related questions
What is knuckle cracking? Here's some of what we know about knuckle cracking The "cracking" of knuckle cracking seems to be produced by increasing the space between finger joints. This causes gas bubbles in the joint fluid to collapse or burst. It's a bit like blowing up a balloon and then stretching the walls of the balloon outward until it pops.
Why do Knuckles crack? When you crack your knuckles, the sound is coming from the compression of nitrogen, oxygen and carbon dioxide bubbles that naturally occur in the spaces of the joints, Dr. Stearns says. The cracking is the sound of gas being released from the joint, an action called cavitation, Dr. Stearns further explains.
What happens if you crack a knuckle? Cracking joints may create a vacuum that the gases then fill. And when a person pulls a finger to crack their knuckle, for example, the sudden, dramatic increase in surrounding pressure pops the gas bubbles, partially or totally, making a sound. This formation and collapse of bubbles is called “cavitation.” Synovial fluid is fluid within joints.
Does cracking knuckles make a difference? No differences have been seen in regards to grip strength or pain experienced before or after cracking. While there was an increase in range of motion seen, this difference was quite small. The relative increase in range of motion seen in pre- versus post-cracked knuckles measured about 5 degrees. What about long-term consequences?
