Embedded Stroke Evaluation System

This project aims to create an embedded system that enables occupational therapists to objectively assess stroke severity in patients. By measuring and recording wrist pressure, force, position, and speed, the system provides valuable data to facilitate effective rehabilitation. Components include a keypad, LCD display, three force sensors, and a potentiometer, allowing therapists to interact with the system easily. Furthermore, data will be sent to a PC for comprehensive analysis and reporting, enhancing the therapists' ability to track patient progress over time and improve mobility outcomes.

  1. Embedded Stroke Evaluation System Amanda Sweeney 4ECE Supervisor: Martin Glavin

  2. Background Information • A stroke occurs when the blood supply to a part of the brain is suddenly reduced or cut off, causing the affected area of brain tissue to die • When an individual suffers a stroke, muscles in their arms and legs can tighten significantly, resulting in reduced mobility • Occupational Therapists work with patients to regain lost function by developing programs of activity that gradually increases in complexity to improve strength

  3. Project Abstract • This project involves the development of an embedded system that will allow an occupational therapist to objectively and accurately measure the severity of stroke suffered by patients in their care • The system will measure and record pressure, force, position and speed of the wrist action, to allow the therapist to assess the severity of the stroke

  4. Approach to Project • The basic system will integrate a keypad, LCD, three force sensors and a potentiometer • The outputs from the force sensors and the potentiometer will be displayed on the LCD screen

  5. … Approach to Project • A serial interface to the PC must also be developed, so that the final system will be capable of displaying the information on a PC • The therapist will be able to interact with the system through the use of the keypad • A buzzer will be used to alert the therapist of important information

  6. Approach to Project • The final system must be simple for the therapist to navigate • The data sent to PC will be compiled into a report and the pressures, positions and speeds will be displayed on a graph for evaluation by the therapist

  7. Project Ideas … • Occupational Therapist’s Idea • Impractical to have the display on the patient while working with them

  8. … Project Ideas • Final design will incorporate the occupational therapists idea’s but from an engineering perspective • The LCD display will not be on the wrist splint • The data will also be sent to a computer, for review by the occupational therapist after the session and in future sessions
