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

Embedded Stroke Evauluation System

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

Embedded Stroke Evauluation System

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

Embedded Stroke Evauluation System

… 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

Embedded Stroke Evauluation System

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

Embedded Stroke Evauluation System

Project Ideas …

• Occupational Therapist’s Idea

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

Embedded Stroke Evauluation System

… 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
