It has recently been proposed that the ataxia in ataxic hemiparesis is a clumsiness common to all patients with hemiparesis and not indicative of any involvement of corticopontocerebellar or cerebellocortical pathways. In disagreement with this view, we report here that a patient with ataxic hemiparesis, following a lesion of the corona radiata, showed the disorders in kinematic and electromyographic (EMG) parameters of goal‐directed movements that have recently been demonstrated to be characteristic of patients with cerebellar lesions. This suggests involvement of corticopontocerebellar or cerebellocortical pathways in ataxic hemiparesis.
