Introduction

The Internet of Things (IoT) technology in healthcare has paved the way for innovative solutions to enhance patient care. One such advancement is the development of telerehabilitation. The prototype of the system we created for our client, a startup that provides personalized, remote physical therapy is an excellent example of what can be achieved with a lot of knowledge and minimal funding.

Development Process of the Product

The telerehabilitation system combines wearable muscle sensors, a motion controller, and a camera to facilitate interactive physical therapy at home. The development involved several key stages:

1. Conceptualization and Design: Since our client is a startup, the initial phase focused on identifying the possibilities of adapting gaming equipment and simple, already available solutions for remote rehabilitation solution. We incorporated IoT technologies to monitor and guide patients effectively during physical therapy exercises.
2. Sensor Integration: The system utilizes muscle sensors that measure muscle activation via electrical potential. These sensors are connected to a microcontroller (such as Arduino) to gather electromyography (EMG) data. Motion controller and a camera are employed for body tracking capabilities, allowing for detailed monitoring of patient movements.
3. Software Development: Custom software was developed to process data from the sensors, camera, and motion controller. This software provides real-time feedback, tracks progress, and adapts exercises based on patient performance. 
4. Pilot Implementation: Early experiments were conducted to validate the system’s feasibility and effectiveness. These trials involved real people who volunteered to gather data on the system’s performance and make necessary adjustments.

Main Groups of Patients

The telerehabilitation system is designed to cater to a wide range of patients requiring physical therapy, including:

1. Neurological Patients – Individuals suffering from strokes, traumatic brain injuries, cerebral palsy, or other neurological conditions benefit from this system. It helps in regaining motor skills and improving coordination.
2. Musculoskeletal Patients: Patients with musculoskeletal disorders and trauma, such as those recovering from surgeries or dealing with chronic pain, may use this system for rehabilitation to restore function and reduce pain.
3. Cardiovascular Patients: The system assists cardiovascular patients in managing conditions that require monitored physical activity to improve cardiovascular health, such as hypertension, aneurysms, recovering from heart attacks, and others.
4. Elderly Population: Elderly patients who require rehabilitation for various age-related conditions find this system beneficial due to its ability to provide therapy in the comfort of their homes.

Main Reason for Creation

The primary motivation for developing the telerehabilitation system was to address the limitations of traditional rehabilitation services, especially in the trying times of COVID-19, when the possibilities of receiving the proper care were severely limited. Key reasons include:

1. Accessibility: Rehabilitation centers are often limited in capacity and geographic reach. This system enables patients to receive quality therapy regardless of their location.
2. Cost-Effectiveness: Frequent travel to rehabilitation centers can be costly and time-consuming. The system reduces these expenses by allowing patients to undergo therapy at home.
3. Continuous Monitoring: The IoT-enabled system provides continuous monitoring of patients’ progress, offering data-driven insights that can improve treatment outcomes.
4. Insight: The data from the system might be presented to the physicians and doctors, for a better understanding of patients’ condition and adjustment of prescribed activity.
