Dysdiadochokinesia
Also known as Dysdiadochokinesis
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. Impaired pronation/supination of the upper extremities, hand/finger tapping, and heel-to-shin test are some clinical ways to test for dysdiadochokinesia. Causes can either be from cerebellar or extrapyramidal origin. Management inc

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. Impaired pronation/supination of the upper extremities, hand/finger tapping, and heel-to-shin test are some clinical ways to test for dysdiadochokinesia. Causes can either be from cerebellar or extrapyramidal origin. Management includes treating the underlying cause and neurorehabilitation therapies.
== History of name and origin == The term dysdiadochokinesia came into fruition in 1902 after the neurologist Joseph Francois Félix Babinski observed patients with cerebellar lesions. He noticed that these patients could not perform rapid, alternating movements of agonist and antagonist muscles. During this time period, neurophysiologists discovered that voluntary movements came from the cerebellum. The term has the Greek roots, "dys", "diadochos", "kinesis", meaning impaired, succeeding, and movement, respectively.
