Tandem gait is a gait (method of walking or running) where the toes of the back foot touch the heel of the front foot at each step. Neurologists sometimes ask patients to walk in a straight line using tandem gait as a test to help diagnose ataxia, especially truncal ataxia, because sufferers of these disorders will have an unsteady gait. However, the results are not definitive, because many disorders or problems can cause unsteady gait (such as vision difficulties and problems with the motor neurons or associative cortex). Therefore, inability to walk correctly in tandem gait does not prove the presence of ataxia.
Profoundly affected tandem gait with no other perceptible deficits is a defining feature of posterior vermal split syndrome.
Suspects may also be asked to perform a tandem gait walk during the "walk and turn" part of a field sobriety test.
Famous quotes containing the words tandem and/or gait:
“We are bare. We are stripped to the bone
and we swim in tandem and go up and up
the river, the identical river called Mine
and we enter together. No one’s alone.”
—Anne Sexton (1928–1974)
“Now a Jew, in the dictionary, is one who is descended from the ancient tribes of Judea, or one who is regarded as descended from that tribe. That’s what it says in the dictionary; but you and I know what a Jew is—One Who Killed Our Lord.... And although there should be a statute of limitations for that crime, it seems that those who neither have the actions nor the gait of Christians, pagan or not, will bust us out, unrelenting dues, for another deuce.”
—Lenny Bruce (1925–1966)
