Measurement Application

2. Hand Tremor
 Parkinson’s Disease (PD) affect one million people only
in US (4 million worldwide)*
 14th leading cause of death in US
 Economic burden: 6 billion USD annually
 Expected to increase substantially in the next years due
to the aging of the population
 Most common symptom: constant shaking of muscles
(hands, fingers, writs, neck, and face)
 Other muscular disorders also share this symptom

3. Symptom evaluation
 Physician observe the tremor
 Patient evaluate the intensity with a 1 to 10 scale
 Other approaches:
◦ Gloves
◦ Individual accelerometers
◦ Touch screens
◦ Wearables (wristbands)
◦ Smartwatches

4. Problem with current
approaches
 Patient evaluation is subjective to emotional stress
 Physician observation lacks precision
 Other approaches:
◦ Require instrumentation
◦ Do not provide accurate data for each finger, writs, and palm
 The precise measurement of hand parts with tremor can:
◦ Help diagnose the stage of the symptom
◦ Avoid a physical appointment with a doctor
◦ Track the symptom’s evolution over time
◦ Creates a global database with precise information about the
symptom
◦ Provide valuable data for products, services, treatments, and

5. HTMA – Hand Tremor Measurement
Application
 HTMA uses the hand/finger tracking of the Intel®
RealSense™ Developer Kit and the Creative Camera
 22 data points are computed for each hand:
◦ Only the average X and Y micro variation for each finger, palm, and
wrist is stored
 A 10 seconds session for each hand gathers the writs,
palm, and five fingers micro variations
 A CSV text file is generated after the session and it is
ready for database import, graph generation, and
analysis
 The interface shows line graphs with the X and Y
variation for each finger, palm, and wrist
 Overall movement variation is also shown and stored

8. HTMA - Conclusion
 Parkinson’s Disease and other muscular disorders have hand
tremor symptoms
 Current approaches to measure tremor are subjective, lack
precision, or require instrumentation
 HTMA provide accurate micro variations measurements of
palm, wrist, and fingers
 Avoid a physical visit to the doctor to check the symptom
progression during a treatment or therapy
 Future features: other hand/finger positions and Z dimension
variation
 The data gathered can be used to:
◦ Help diagnose diseases and symptom progression over time
◦ Classify symptoms stages from a global database
◦ Provide precise data to new treatments, therapies, services, and
