Research output: Contribution to journalArticlepeer-review


The quantitative assessment of tremor represents the main difficulty in clinical evaluation. We developed a software package - T-Lab - for the biomechanical analysis of hyperkinetic movement disorders. This software can receive and elaborate data from an electronic device interfaced with a personal computer. The aim of our study was to verify the validity of the PC-aided method proposed in the routine assessment of tremor. We did this by a correlation (regression) analysis between the scores obtained by Webster's Amplitude Clinical Scale and the amplitude data by T-Lab and between EMG data and frequency measures of T-Lab. Forty-seven patients presenting with upper limb tremor were enrolled. Four series of data were obtained: two series for frequency and two for amplitude. A significant correlation between all sets of data compared was found. T-Lab represents a valid, objective and useful device of quantifying tremors in clinical practice.
