MedMotion is a German digital health company developing a cloud-based platform for continuous remote monitoring of Parkinson's disease motor symptoms. Founded in Munich, MedMotion's system integrates smartphone-based assessments with wearable sensor data to provide objective, longitudinal measurement of tremor, bradykinesia, dyskinesia, gait, and postural instability. The company focuses on enabling clinicians to remotely track disease progression and treatment response without requiring clinic visits, which is particularly valuable for the progressive and fluctuating nature of Parkinson's disease.
MedMotion addresses the fundamental challenge that clinical assessment of Parkinson's disease occurs in episodic snapshots during office visits, while the disease itself manifests with continuous, day-to-day fluctuations that cannot be captured in brief examinations. By providing continuous remote monitoring, the company enables more informed clinical decision-making and more sensitive clinical trial endpoints.
MedMotion's smartphone application enables patients to perform standardized motor assessments:
- Tremor assessment: Finger-tapping and postural tremor tests using phone accelerometer and gyroscope
- Bradykinesia measurement: Finger-tapping speed, amplitude, and rhythm analysis
- Dyskinesia screening: Movement pattern analysis to detect involuntary choreiform movements
- Gait analysis: Walking tests using phone sensors to measure stride length, cadence, and variability
- Postural stability: Sit-to-stand and standing balance tests
The platform also integrates with:
- Wrist-worn inertial sensors: Continuous tremor and movement monitoring
- Accelerometer patches: Adhesive sensors for prolonged monitoring periods
- Smartwatch data: Integration with consumer smartwatch platforms
- Medication tracking: Wearable-based medication reminder and logging systems
MedMotion's backend provides:
- Signal processing pipeline: Automated filtering and feature extraction from raw sensor data
- Machine learning classification: Algorithms to classify movement patterns into PD symptom categories
- Trend analysis: Longitudinal tracking of symptom severity and variability over time
- Clinical reporting: Summarized reports for clinician review between clinic visits
- Alert system: Notification of significant changes requiring clinical attention
The platform specifically addresses:
- Tremor quantification: Frequency, amplitude, and pattern of resting and action tremor throughout the day
- Bradykinesia tracking: Movement speed and amplitude changes correlating with ON/OFF medication states
- Dyskinesia detection: Identification and quantification of levodopa-induced involuntary movements
- Gait monitoring: Detection of shuffling gait, festination, and freezing of gait patterns
- Motor fluctuations: Tracking of ON/OFF time to optimize medication dosing
MedMotion supports:
- Medication reminders: Customizable alerts for levodopa and other PD medications
- ON/OFF time correlation: Linking symptom fluctuations to medication timing
- Dose optimization: Data-driven recommendations for medication adjustments
- Caregiver alerts: Notification of missed medication doses or significant symptom changes
The platform enables:
- Remote consultations: Clinicians review symptom data to prepare for telemedicine visits
- Virtual PT sessions: Integration with tele-rehabilitation services
- Care team coordination: Data sharing between neurologists, physical therapists, and primary care

Studies demonstrate:
- High patient adherence: Remote monitoring is well-accepted by PD patients for extended periods
- Correlation with clinical scales: Digital measures correlate with MDS-UPDRS motor scores
- Detection of subtle change: Sensitive to smaller changes than clinical rating scales
- Reduction in clinic visits: Remote monitoring reduces need for frequent in-person assessments
