Pocket PD: Track Parkinson’s Symptoms & Medication
The University of Tokyo has developed Pocket PD, a mobile application designed to support individuals living with Parkinson’s disease. This tool helps users monitor their medication schedules and track "off" episodes—periods when symptoms worsen despite medication. By recording symptoms, completing structured assessments, and capturing video evidence, patients can gain deeper insight into their condition.
The app is tailored for patients seeking better self-management and improved communication with healthcare providers. It enables users to visualize symptom patterns over time, making it easier to identify triggers and adjust treatment plans. Real-world use cases include daily symptom logging before doctor visits, recording motor fluctuations during "off" periods, and sharing documented data with medical teams.
The app also integrates the MASAC-PD31 questionnaire, a validated tool for assessing both motor and non-motor symptoms. While the developer did not specify additional system requirements, the application is designed to run on modern smartphones with standard health tracking capabilities.
Key Features & Capabilities
- Medication Tracking – Users can log doses and times of medication, helping to maintain consistency and identify timing patterns that may affect symptom control.
- Off Symptom Visualization – The app displays "off" episodes on a timeline, allowing patients to correlate symptom severity with medication intake and daily activities.
- MASAC-PD31 Questionnaire Integration – A clinically validated tool embedded within the app to assess motor and non-motor symptoms, providing structured feedback for both patients and clinicians.
- Video Documentation – Patients can record short videos of their symptoms during "off" periods, offering visual evidence that enhances clinical evaluation.
- Doctor Communication Support – The app highlights key discussion points for medical appointments, helping patients prepare and make the most of limited consultation time.
- Progress Tracking – Users can review historical data to observe symptom trends and medication effectiveness over time.
These features support a proactive approach to managing Parkinson’s disease. For example, a patient might record a tremor episode after missing a dose, then use the timeline to show their doctor how timing affects symptom severity. The video feature allows for objective documentation of gait changes or facial masking, which are often difficult to describe verbally. By integrating validated assessment tools, Pocket PD ensures that patient-reported data meets clinical standards, increasing its usefulness during medical consultations.
User Interface, Workflow & Performance
The user interface of Pocket PD is designed with accessibility and clarity in mind, featuring intuitive navigation and minimalistic layouts. Users can access core functions—medication logging, symptom recording, and questionnaire completion—through a centralized dashboard. The workflow is streamlined to reduce cognitive load, which is especially important for individuals managing a chronic neurological condition.
Tasks such as starting a symptom entry or recording a video are accomplished with few taps, promoting consistent use. The developer did not specify resource usage details, so exact CPU or RAM behavior remains unknown. However, based on its 50MB size and mobile-first design, the app is expected to operate efficiently on standard Android and iOS devices.
Stability is assumed to be solid, given its development by a reputable academic institution. Performance observations are based on general software behavior patterns, and no issues with crashes or lag were reported in the provided materials.
Compatibility & System Requirements
Pocket PD is available for both Android and iOS platforms, ensuring broad accessibility for smartphone users. The software version is 1.0.0, with a download size of 50MB, indicating a lightweight installation. The developer did not provide detailed system requirements, so specific hardware specifications such as minimum RAM or processor speed are not available.
Compatibility information was partially provided, and users should ensure their device meets standard smartphone requirements for running modern health applications. The app is designed to function on devices with built-in cameras and reliable internet connectivity, as video recording and data synchronization may be required. For users with older devices, performance may vary, though no compatibility issues were reported in the official release notes.
