Incoordination

Incoordination a lack of normal adjustment of muscular action so that the intended movement of the limb or other part is not made smoothly and harmoniously, and does not accurately achieve its objective.

If the abnormality is hypermetric, the condition is referred to as ataxia. If it is inclined to weakness, e.g. knuckling at the turn, stumbling, failure to flex limbs properly, or to misdirection as in a proprioceptive deficit, it is called incoordination.

The judgment is best made with the animal going at a good pace, preferably unrestrained, and on level going.

As affecting sphincters, especially of the alimentary tract, the term is used alternatively to achalasia.
