Computer-aided tremor
analysis, using optical
recognition system
Multi-disciplinary approach
                Trepetlika – Association of Patients
                 with Parkinson’s Disease in
                 Slovenia

                Wise Technologies Ltd. – Innovative
                 software solutions company
                 Ljubljana

                Neurology Clinic, University
                 Clinocal Center, Ljubljana

                Institute for Pathophysiology,
                 Medical faculty, Ljubljana
Parkinson’s disease
 tremor
 bradykinesia
 rigidity
 postural instability
Need for quantification
 Objectivity
 Differential diagnosis (PD, ET,
  psychogenic..)
 Tremor progression
 Treatment follow-up
Why optical measurements?
 Precise measurements of tremor
  parameters
 Keeping track of the patients history –
  video clips, measurements, comments
 Excluding subjectivity
 Objective comparison of recorded
  measurements
How we use the system?
                Up to 32 different,
                 color-coded markers
                Tremor tracking with
                 1-4 cameras
                3D measurements
                 with two cameras
                Comprehensive
                 analysis
Friendly user interface
Powerful analysis
                  Graphs of horizontal
                   and vertical motion
                  X/Y graph
                   reproducing tremor
                  Frequency analysis
                  Comparing tremors
                   on diff. extremities
Future development!
 Design of a low-cost system for private
  use.
 Adding more analysis, giving doctors an
  instrument for tremor research
 To enable physicans to use the patient’s
  measurements for follow-up of tremor
