Dyskinesia analysis. Histogram analysis of cineseismograms of human dyskinesia.

The report presents a method developed to analyze strip chart records generated by a system previously described and termed cineseismography which makes available quantitative records of abnormal involuntary movements in the human. In this report, method for converting measurements made on the strip chart record is described. Application of the method is made in three cases with diagnosis of Huntington's disease (chorea). Case histories are presented for each subject detailing the medications and dosage, and the quantitative data together with the histograms derived are provided. Preliminary trials indicate that movement decomposition, as in ataxia, can also be detected and quantified.
