Incoordination
Pronunciation: in-koh-OR-din-ay-shun
Impaired ability to perform smooth, accurate voluntary movements due to neurological dysfunction affecting motor control.
Full Definition
Incoordination refers to the inability to execute smooth, precise, and well-timed voluntary movements, typically resulting from dysfunction of the cerebellum, basal ganglia, or sensory systems. In rehabilitation medicine, incoordination manifests as difficulties with fine motor tasks, balance disturbances, dysmetria (overshooting targets), dysdiadochokinesia (impaired rapid alternating movements), and intention tremor. Assessment of incoordination involves standardized tests such as finger-to-nose, heel-to-shin, and rapid alternating movement tasks. Treatment focuses on repetitive practice, balance training, and compensatory strategies to improve functional performance.
Usage
Usage note: Distinguish from general weakness - incoordination implies adequate strength but impaired motor control.
