title: Reversible pseudoathetosis and sensory ataxic gait caused by cervical spondylotic myelopathy.
abstract: Proprioceptive deafferentation of spinal cord origin can cause pseudoathetosis, sensory ataxic gait, or both. The co-existence of pseudoathetosis and sensory ataxic gait caused by a surgically treatable condition of the spinal cord has been rarely reported. An 80-year-old man with cervical spondylotic myelopathy presented with severe sensory ataxic gait which confined him to a wheelchair. He also had poor control of his hands due to the pseudoathetoid movements of the fingers, which prevented him from sustaining constant muscle contraction. He underwent C3-4 and C4-5 anterior discectomies and anterior fusion. His neurological deficits gradually improved after the decompressive surgery. About 7months postoperatively, he was totally independent in activities of daily living and needed no mobility aid. This case highlights the clinical importance of recognizing a surgically treatable and reversible condition of the spinal cord that causes pseudoathetosis and sensory ataxic gait.
