About The Project

Patients recovering from knee surgery can have inferior long-term mobility if they do not perform specific rehabilitation exercises soon after surgery. Rehabilitation can fail if the patient does not begin it immediately after surgery, or if they do not have good compliance to the treatment plan. We present a device to assist patients and physicians with visualization of the rehabilitation process, to help them make better decisions about how to tailor a recovery plan. The device can display real time muscle activity feedback using reusable fabric electrodes with equivalent sensitivity to a much more expensive commercial sensor, and store and process the data to provide clinical information.

Design

The system architecture of data communication is shown in figure 1. Product Name Screen Shot

Electrical and Hardware

The system uses pairs of fabric electrodes integrated into a wearable device to detect muscle activity from the patient. A circuit was implemented to amplify and filter the signals before passing them to a microcontroller, and the EMG signal sensitivity can be adjusted using an integrated potentiometer. The bluetooth module HC-05 is used to communicate between the signal detection circuit and the mobile application. Data sampling rate is currently set to 1KHz.

Mobile applicaton

The mobile app was implemented using React Native open-source mobile application framework. It supports user authentication, Bluetooth connectivity for real-time data monitoring, recording of monitored data, and uploading to cloud computing for further processing. It also allows one to see the archive of previous measurements and their corresponding analysis.

Cloud computing

The project utilizes Google firebase product which powers up authentication and cloud data storage functionalities. Firebase was chosen due to its robustness and sensitive data safety. Backend analysis is implemented using python3.7 open source programming language which is mainly used for EMG signal analysis, filtration, and processing with the data collected from the cloud. The dataset we created from various sources used to recognize muscle recovery over time and muscle fatigue level.
