Problem Statement

• To develop an interactive, web-based
  strengthening and testing program for patients
  with multiple sclerosis-induced hand weakness for
  use in the home. The program will focus on the
  lateral pinch exercise and be user-friendly for
  new or inexperienced users.

4
Background Information

• Autoimmune disease
• Myelin damaged
• Scar tissue called sclerosis

5
Epidemiology

• Northern climates
• Twice as many women as men
• Ages 20-40

6
Possible Factors

• Genetic
• Environmental
• Infectious agents

7
Treatments

• Methylprednisolone
• Immunomodulatory
• Exercise

8
Treatment of Hand Tremors

• Daily practice and monitoring
• Currently all tests occur in a hospital setting
  using
• DOS program
• Transducer
• Amplifier
• Signal generator

9
Control Test

• Line produced by patient matches stationary line

10
Strength and Speed Test

• Patients squeezes the pinch as hard as possible
  as quickly as possible
• Tests the patients maximum strength as well
  their ability to reach the maximum

11
Motivation

• The importance of regular testing for effective
  treatment
• Cost of testing
• Transportation issues

12
Product Design Specification

• Assume patients have home computers with at least
  dial-up Internet access
• Monitor performance using software
• Send data to UW Neurology Dept. server
• Manual needed
• Absence of computer vernacular essential
• Audio and visual guidance

Software Implementation(specifications)

• The program must record convert incoming data
  from a transducer (via USB port).
• Data needs to be calibrated from electrical input
  to represent force.
• After the conversion, the numeric values of load
  applied will be plotted vs. time.
• Information must be made available for physicians
  to analyze.

21
Design Alternatives

• 1. Client-Based Programming
• 2. Web-Based Programming

22
Client-Based Application

• Visual Basic or Java application on hard drive
  direct patient through test.
• Test data processed and stored locally.
• Application linked to Neurology database with
  ADO.net.

23
Client-Based (cont.)

• Advantages
• Faster more powerful
• Can include more graphics accessories
• Compatible with 56K modem

• Disadvantages
• Harder to update
• Application can crash

24
Web-Based Application

• Program which instructs patient located on
  website.
• Written using server-side programming languages
• JAVA HTML PEARL
• Run and directly accessed by Neurology server

25
Web-Based (cont.)

• Advantages
• Accessible anywhere
• Updating can be done at one place

• Disadvantages
• JAVA applets/ JavaScript have difficulty
  accessing USB ports.
• Slower
• Cannot support much graphics
• Internet or server can crash
