Material and Methods

Our system integrates wearable sensors, real-time signal processing, wireless data transmission, and multi-modal analytics to deliver continuous, accurate, and non-invasive monitoring of Parkinson’s tremors in everyday environments. Designed as part of custom software development for healthcare, this solution ensures reliable performance in both clinical and home settings.

The system features a compact, three-axis accelerometer (LIS33LDH by STMicroelectronics) with a ±2 g range and 1 mg/digit sensitivity, ideal for capturing subtle tremor movements. Worn on the wrist, the sensor records motion data at 100 Hz, ensuring accurate detection of 4-6 Hz Parkinsonian tremors. A high-pass filter (0.25 Hz cutoff) removes gravitational interference, isolating tremor-specific signals. The module operates as part of a platform built by a healthcare software development company, ensuring adaptability for real-world medical applications.

All sensor data streams undergo sophisticated signal processing using Short-Time Fourier Transform (STFT) algorithms to handle non-stationary biological signals effectively. The system processes data in 5.12-second windows with overlapping segments to capture dynamic symptom variations. Machine learning algorithms analyze temporal patterns, frequency characteristics, and amplitude variations to extract meaningful health indicators. Advanced filtering techniques isolate relevant signal components while removing motion artifacts and environmental noise, showing the value of custom healthcare software development company expertise in building advanced analytics frameworks.

A Bluetooth module (Rev. 2.1+EDR) enables seamless data transfer to mobile devices or PCs for further analysis. This wireless connectivity supports real-time monitoring and data logging, making the system suitable for both clinical and home use. By leveraging custom software development for healthcare, the system ensures scalability and interoperability with existing medical devices.

The platform integrates wearable sensor data with patient-reported outcomes and clinical questionnaires to provide comprehensive health assessments. For neurological monitoring, the system incorporates Parkinson’s Disease Non-Motor Symptoms (PDNMS) questionnaires alongside movement data. Advanced stacking algorithms combine predictions from multiple data sources to enhance overall diagnostic accuracy and reduce false positives. Such integration highlights the strengths of a custom healthcare software development company in designing end-to-end solutions.

Cloud-based infrastructure ensures HIPAA-compliant data transmission and storage while providing healthcare providers with real-time access to patient information. The platform supports integration with electronic health records (EHR) systems and telemedicine platforms for seamless care coordination. By applying custom software development for healthcare, the system bridges wearable technology with secure digital health ecosystems, making it a reliable innovation from a healthcare software development company.

The system's cost-effectiveness shows clear return on investment within the first year of implementation.

Abstract

Parkinson’s Disease (PD) affects millions worldwide, with tremors being a hallmark symptom that impacts daily life. Early detection and continuous monitoring of tremor intensity are crucial for effective treatment management and improved patient quality of life. But modern healthcare faces unprecedented challenges when it comes to deliver personalized, continuous patient care while managing costs and improving outcomes. SB Infowaves introduces an AI-integrated, accelerometer-based system designed for real-time tremor detection and severity analysis in PD patients. This low-cost, wearable solution leverages smart sensor data, short-time Fourier transforms (STFT), and advanced machine learning algorithms to assess tremor types, frequency, and intensity. With real-time data analysis and intuitive interfaces, our system transforms PD care from reactive to preventive, improving quality of life and treatment outcomes.

However, many challenges remain to developing a system that can robustly distinguish PD motor symptoms from normal motion. Stronger feature sets may help to improve the detection accuracy of such a system. In this work, we explore several feature sets compared across two classification algorithms for PD tremor detection. We find that features automatically learned by a Convolutional Neural Network (CNN) lead to the best performance, although our handcrafted features are close behind.

Introduction

The global population is aging, and with it, the prevalence of neurodegenerative conditions like Parkinson’s Disease is on the rise. PD, a neurological disorder characterized by the progressive degeneration of dopamine-producing neurons, leads to debilitating motor control issues such as tremors, muscle rigidity, slowed movement (bradykinesia), and postural instability.

Traditional healthcare delivery relies heavily on periodic clinical visits and subjective symptom reporting, often missing critical changes in patient conditions between appointments. What if PD monitoring could shift from episodic checkups to seamless, continuous tracking at home? What if patients and physicians could receive quantifiable insights into tremor patterns in real time?

At SB Infowaves, we’ve developed a robust accelerometer-based solution that transforms healthcare monitoring for PD patients. With AI-driven diagnostics enhancing precision and efficiency in medical analysis, IoT technologies are developing highly individualized treatment plans by analyzing medical images, laboratory results, and patient histories to identify patterns and anomalies indicative of specific health conditions. The system integrates seamlessly with existing healthcare infrastructure, which deliver immediate value through early detection capabilities, personalized treatment optimization, and enhanced patient engagement.
