Dysdiadochokinesia (DDK) is the medical term for an impaired ability to perform rapid, alternating movements (i.e., diadochokinesia). Complete inability is called adiadochokinesia. The term is from Greek δυς dys "bad", διάδοχος diadochos "working in turn", κίνησις kinesis "movement". The term was first described by neurologist Joseph Francois Félix Babinski in 1902.
