Did your parents always warn you not to crack your knuckles otherwise you would end up getting arthritis in your hands? For many years now, repeated knuckle cracking has long been thought of as a leading contributor to joint trouble, particularly arthritis.
A recent case-controlled study in the Journal of the American Board of Family Medicine (1) has put this old wives tale to the test. They examined the connection between habitual knuckle cracking and eventual osteoarthritis. Interestingly, they found that there was no correlation between habitual knuckle cracking and hand arthritis.
In the same study, they also put forward the question as to why individuals crack their knuckles. The author proposed that it actually causes temporary relief to joint stiffness and reduces symptoms of arthritis. It’s also suggested that when one cracks their own knuckles it has close neurological relationship between the hands and the cortex of the brain. Meaning, manipulating the knuckles has a profound stimulatory effect upon the cortex and may serve as a ‘manual caffeine’ to give us a mental lift.
