Athetosis and dystonia are well known clinical signs, described in disorders of basal ganglia. As opposed to pseudoathetosis, true athetosis was hitherto not reported in cord lesions. We here report three patients with athetosis and dystonia of hands due to intramedullary lesions of cervical cord: two patients with syringomyelia and one with glioma. Even though pseudoathetosis can be produced by lesions of posterior columns and likely to be confused with the involuntary movements of our patients, they had clinical and EMG findings consistent with true athetosis. A possible explanation for the athetosis and dystonia due to cord lesion is being postulated.

Two cases of severe thyrotoxicosis are described. They both exhibited choreo-athetoid movements which were abolished by successful treatment of the thyrotoxicosis. It is suggested that the tremor of mild thyrotoxicosis is one end of a spectrum at which choreo-athetosis is at the most severe end. A tentative explanation of this hypothesis is given in the discussion.

Prior work has highlighted the challenges faced by people with athetosis when trying to acquire on-screen targets using a mouse or trackball. The difficulty of positioning the mouse cursor within a confined area has been identified as a challenging task. We have developed a target acquisition assistance algorithm that features transition assistance via directional gain variation based on target prediction, settling assistance via gain reduction in the vicinity of a predicted target, and expansion of the predicted target as the cursor approaches it. We evaluated the algorithm on improving target acquisition efficiency among seven participants with athetoid cerebral palsy. Our results showed that the algorithm significantly reduced the overall movement time by about 20%. Considering the target acquisition occurs countless times in the course of regular computer use, the accumulative effect of such improvements can be significant for improving the efficiency of computer interaction among people with athetosis.

Revue Neurologique Jan 2004Paraneoplastic choreo-athetoses are rare. We report a case of anti-Hu syndrome with choreo-athetosis.
INTRODUCTION
Paraneoplastic choreo-athetoses are rare. We report a case of anti-Hu syndrome with choreo-athetosis.
CASE REPORT
A 48-year-old woman developed a small-cell lung carcinoma revealed by an anti-Hu syndrome. The neurological features included choreo-athetosis predominating in the upper limbs, chronic sensorimotor axonal polyneuropathy, and opsoclonus. The cerebrospinal fluid was acellular and contained several oligoclonal IgG bands, not found in the corresponding serum. Magnetic resonance imaging revealed bilateral high-intensity lesions on T2/FLAIR sequence in the corona radiata. Moderate transitory improvement of the paraneoplastic neurological syndrome was observed after several carboplatin-etoposid cycles.
CONCLUSION
A paraneoplastic origin must be considered in all cases of unexplained choreo-athetosis. Paraneoplastic choreo-athetosis is most often associated with other neurological symptoms. The most frequent associated tumor is a small-cell lung carcinoma with anti-CRMP5 and/or anti-Hu antibodies. Our patient developed paraneoplastic choreo-athetosis related to an anti-Hu syndrome in the absence of anti-CRMP5/CV2 antibodies. Paraneoplastic choreo-athetosis might result from a central lesion, and/or from proprioceptive deafferentation subsequent to peripheral neuropathy.

Review
Paroxysmal Choreoathetosis (PC) is a rare disorder which is characterized by spells of involuntary movements of the limbs, the head and the trunk lasting from a minute to several hours. PC is classified in two main types. In Paroxysmal Dystonic Choreoathetosis (PDC) the attacks are prolonged and precipitated by alcohol, emotion or fatigue, in Paroxysmal Kinesigenic Choreoathetosis (PKC) the attacks last less than 5 minutes and are precipitated by sudden movements. Although the pathophysiology of the disorder ist still uncertain, it is supposed to be an extrapyramidal disorder. Clinical features, therapeutical and differential diagnostic aspects are discussed. There is a certain risk that the disorder is misinterpreted as psychogenic or hysterical in nature. The mostly good response to medication can help the patients avoid superimposed emotional problems.
