Embedded Stroke Evauluation System

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


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


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

… 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


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


Project Ideas …

• Occupational Therapist’s Idea

• Impractical to have the display on the patient while working with them


… 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
