hereditary bimanual synkinesis
Last reviewed 01/2018
Hereditary bimanual synkinesis is as its name implies an inherited movement disorder affecting the hands and fingers. In this condition repetitive voluntary movements of one hand are accompanied by involuntary mirrored movements of the other hand.
Individuals affected by this condition do not notice this until it is noticed by others, and it may effect their performance at particular bimanual tasks such as playing the piano, typing or climbing ladders.
This condition may be associated with the the X-linked form of Kallmann's syndrome.
