Explanation: 

Detailed explanation-1: -Dysmetria is the inability to control the distance, speed, and range of motion necessary to perform smoothly coordinated movements.

Detailed explanation-2: -The term dysmetria describes the inability of patients to execute complex movements in which the judgment of distance is impaired and expressed as inaccurate control of the range and direction of movement.

Detailed explanation-3: -The actual cause of dysmetria is thought to be caused by lesions in the cerebellum or by lesions in the proprioceptive nerves that lead to the cerebellum that coordinate visual, spatial and other sensory information with motor control.

Detailed explanation-4: -The first symptoms include progressive ataxia, clumsiness of the hands, loss of proprioception, and areflexia. Other features often observed are dysdiadochokinesia, dysarthria, positive Romberg sign, head titubation, decreased visual acuity, and positive Babinski sign.
