The story

Notes If this word were borrowed on fully traditional principles it would be cinesthesia (or cinaesthesia); compare cinema from the same root. But more often this Greek root is spelled and pronounced with a k, and in the case of kinesthesia this avoids inconvenient homophony with synaesthesia, the sensation of one type of perception as another (e.g. the perception of smells as colors). Nevertheless the words are still occasionally confused; e.g. http://books.google.com/books?ie=UTF-8&vid=ISBN0849303710&id=_u4sZjHHwCYC&pg=PA581&lpg=PA581&dq=cinesthesia&sig=gFEo5BGoW75XcUVTk44aHGKgGuc.
