  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
