FoG Parkinson’s wearable device based on Seeed Studio XIAO RP2040

The objective of this project is to design a wearable device that can assist Parkinson’s patients who experience freeze of gait (FoG) issues. FoG is a common symptom of Parkinson’s disease that causes sudden and temporary episodes of immobility or difficulty initiating movement. The wearable device will aim to provide sensory cues or signals that can help alleviate FoG episodes and improve mobility.

The project will involve researching various technologies and solutions that have been used to address FoG in Parkinson’s patients, such as visual, auditory, or haptic cues. The wearable device will need to be designed to be comfortable, unobtrusive, and easy to use, while also providing effective sensory feedback to the wearer.

Background

FoG is a situation where a patient, usually with Parkinson’s disease, having trouble walking on their own. When FoG occurs, they will have issues like trouble moving their feet forward for next step, reduce walking speed and reduced ability to balance. However, with the help of some external stimulant, like sound, vibration or light, they can restore their normal walking gait very soon by following the rhythm of the external stimulant. That is why we need to make a device that help them “walk normally” in some sense.

The background of this project is rooted in the growing prevalence of Parkinson’s disease and its associated symptoms, such as freeze of gait (FoG). Parkinson’s disease is a progressive neurodegenerative disorder that affects the central nervous system, and is characterized by tremors, muscle rigidity, and impaired movement. FoG is a common symptom of Parkinson’s disease that can significantly impact patients’ mobility, balance, and quality of life.

According to the Parkinson’s Foundation, approximately one million people in the United States are living with Parkinson’s disease, and the number is expected to increase in the coming years due to an aging population. The prevalence of FoG in Parkinson’s patients is also significant, with estimates ranging from 53% to 82% of patients experiencing FoG episodes during the course of their disease.

FoG can lead to falls, injuries, and reduced independence, making it a pressing issue for both patients and caregivers. While there are medications and therapies available to manage Parkinson’s symptoms, they may not always be effective for FoG. External sensory cues, such as auditory, visual, or haptic feedback, have been shown to be an effective and non-invasive method for managing FoG and improving mobility in Parkinson’s patients.

Therefore, the goal of this project is to design a wearable device that can provide sensory cues to Parkinson’s patients when they experience FoG, helping them overcome FoG and restore their normal walking gait. By providing an innovative and accessible solution to this common symptom, the project aims to improve the quality of life and independence of Parkinson’s patients.

The Challenge

When it comes to implementing this project, there are several challenges that may arise. Here are some potential challenges:

User Acceptance: Patients with Parkinson’s disease may have varying degrees of acceptance towards using a wearable device to manage FoG. Some patients may find the device helpful and comfortable, while others may not want to wear it due to concerns about stigma or discomfort.

Design and Functionality: The wearable device will need to be designed to be lightweight, comfortable, and unobtrusive, while also providing effective sensory feedback to the wearer. The device will need to be tested and refined through user feedback to ensure that it meets the needs and preferences of Parkinson’s patients.

Technical Challenges: Developing the technology necessary to provide effective sensory feedback, such as sound, vibration, or light, may be challenging. The device will need to be designed to be power efficient and reliable, and may require extensive testing to ensure its effectiveness.

Regulatory Compliance: Depending on the intended use of the device, there may be regulatory requirements that must be met before it can be marketed and sold. This may include obtaining necessary certifications, such as FDA approval, which can be a lengthy and costly process.

Market Competition: There may be existing products or technologies available to manage FoG in Parkinson’s patients, which could limit the market potential for the device. The device will need to be differentiated from existing solutions and marketed effectively to target audiences.

Overall, the success of this project will depend on its ability to address these challenges and provide a useful and innovative solution for Parkinson’s patients who experience FoG. By understanding these challenges and developing strategies to overcome them, the project has the potential to make a meaningful impact on the lives of Parkinson’s patients.

The Solution

User Acceptance: Involving Parkinson’s patients and caregivers in the design and development process can help ensure that the device meets their needs and preferences. Conducting user testing and gathering feedback on the device’s usability and comfort can also help improve user acceptance.

Design and Functionality: Working with experts in wearable technology and user-centered design can help ensure that the device is designed to be lightweight, comfortable, and effective. Incorporating user feedback and conducting iterative design cycles can help refine the device’s functionality and improve its overall effectiveness.

Technical Challenges: Conducting thorough research and development on the technology necessary for providing effective sensory feedback can help address technical challenges. Partnering with experts in sensory feedback technology can also help ensure that the device is optimized for power efficiency and reliability.

Regulatory Compliance: Engaging with regulatory experts and obtaining necessary certifications, such as FDA approval, can help ensure that the device meets necessary regulatory requirements. Conducting thorough testing and documentation can also help streamline the regulatory process.

Market Competition: Conducting market research and identifying the unique value proposition of the device can help differentiate it from existing solutions. Developing a strong marketing strategy that targets key audiences, such as Parkinson’s patients, caregivers, and healthcare providers, can also help increase market awareness and adoption.

Overall, addressing these challenges will require a collaborative and iterative approach that involves engaging with stakeholders, conducting thorough research and development, and adapting the device’s design and marketing strategies based on feedback and market trends. By implementing these solutions and strategies, the project can increase its chances of success in providing a useful and innovative solution for Parkinson’s patients who experience FoG.

The Results

Improved Mobility: The wearable device can provide sensory cues to Parkinson’s patients when they experience FoG, helping them overcome the symptom and restore their normal walking gait. This can lead to improved mobility, balance, and overall quality of life for patients.

Increased Independence: FoG can limit patients’ ability to perform daily activities and reduce their independence. By managing FoG with a wearable device, patients can regain their ability to move independently and perform daily tasks with greater ease.

Cost-Effective Solution: Compared to other medical interventions, such as medications or surgeries, a wearable device can be a cost-effective solution for managing FoG in Parkinson’s patients. This can reduce healthcare costs for patients and healthcare systems.

User-Centered Care: The wearable device can be designed based on user-centered principles, taking into account patients’ needs, preferences, and feedback. This can provide a more personalized and effective solution for managing FoG, improving patient satisfaction and engagement.

Innovation and Advancement: Developing a wearable device to manage FoG in Parkinson’s patients can contribute to the advancement of technology and medical care. The device can also serve as a platform for further research and development in the field of Parkinson’s disease and wearable technology.

Overall, completing this project can have a significant impact on the lives of Parkinson’s patients who experience FoG, improving their mobility, independence, and overall quality of life. It can also contribute to the advancement of medical technology and care, leading to potential benefits for patients with other medical conditions.
