BACKGROUND:  Prevalent types of movement disorders (MD) and their etiologies are likely to differ with region. Response to therapy in MD  is unpredictable.

AIM:  To study  spectrum and  etiology of MD seen  at a tertiary care  public hospital in northern India and  document response to therapy.

METHODS: Consecutive patients presenting with MD as the main complaint were enrolled.    History and examination were charted in predesigned data collection forms.  Two minute video was taken.  Cerebral palsy was excluded.  Investigative work up was done as required  to establish etiology.  Severity was assessed by Battini scale. Treatment given was charted and response assessed by repeat  video and parental report after 2 and 4 weeks.

RESULTS:  71 patients were enrolled [mean (SD) age in months  67.4 (45.2) ; boys  64.8%]. 44 inpatients,  27 outpatients.  The most common MD was dystonia  [17 patients (23.9%)] followed by tremor [16 patients (22.5%)], ataxia [13 (18.3%)], chorea  [9 (12.,7%)]  hemiballismus [5 patients (7%)], myoclonus and tics in 4 (5.6%) each, while one was unclassifiable.  Initial mean (SD) Battini score for dystonia was 42.9 (8.6) and most common etiology was encephalitis (8 patients).   Initial mean score in tremor patients  was  23.8 (7.4) and most common cause infantile tremor syndrome (ITS) in 9. Mean initial score of chorea was 34.4 (14.2), most common  cause being  rheumatic chorea.  For each MD, etiology and response to therapy will be presented.

CONCLUSIONS:  A wide variety of  MDs  were seen.  Response to therapy can be gauged by  serial scoring.
