MedMotion is a German digital health company developing a cloud-based platform for continuous remote monitoring of [Parkinson's disease](/diseases/parkinsons-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[@medmotion_corp]. 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_platform].
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[@maetzler2013].

Technology Platform
Smartphone-Based Assessment
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[@sinclair2019]
Wearable Sensor Integration
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
Cloud Analytics
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[@rodriguez2020]
Parkinson'S Disease Features
Motor Symptom Monitoring
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[@adss2022]
Medication Management
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[@ossendryver2016]
Telemedicine Integration
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[@maetzler2013]
