The ability to perform rapid alternating movements, especially tested in neurological exams by having patients tap their fingers or alternate hand positions quickly.
From Greek diadochos (successive) + kinesia (movement, from kinein to move). A medical term describing the smooth execution of opposing muscle movements in sequence.
Neurologists use this as a secret test—if you can't do rapid finger-tapping smoothly, it hints at problems in your cerebellum, the brain's 'dance choreographer' for movement!
