PainSci summary of Unger 1998?This page is one of thousands in the PainScience.com bibliography. It is not a general article: it is focused on a single scientific paper, and it may provide only just enough context for the summary to make sense.

This study won an “Ig Nobel Prize,” awarded to Donald L. Unger for diligently cracking the knuckles of his left hand only — never his right — every day for more than sixty (60) years. What did he find? “There was no arthritis in either hand, and no apparent differences between the two hands.… there is no apparent relationship between knuckle cracking and the subsequent development of arthritis of the fingers.”
