Dear Editor:

Compared with cerebral infarction, spinal cord infarction, accounting for 0.3–1% of all strokes, is a rare condition [1]. Posterior spinal cord infarction, accounting for approximately 22% of all spinal cord infarctions, is rarer than anterior spinal cord infarction [1]. Impaired proprioception is a characteristic feature of posterior spinal cord infarction.

Dystonia, associated with impaired sensorimotor integration, is a heterogeneous group of hyperkinetic movement disorders characterized by involuntary sustained muscle contractions that lead to abnormal postures and repetitive movements [2]. The sensory aspects of dystonia include intrinsic sensory abnormalities and the effects of external sensory input on the underlying motor abnormality. The basal ganglia, cerebellum, thalamus, and their connections, coupled with altered sensory input, seem to play key roles in abnormal sensorimotor integration [3]. Both organic brain lesion and altered sensory input will result in...
