emed systems

• There are 2 basic emed systems
• emed-at (clinic)
• emed-st (clinic research)
• The following slides will describe the hardware
  and software options of each system. At the end,
  a summary will be provided to compare the systems.

emed-at system

• There are 2 main configurations for the emed-at
  system
• emed-at 25
• emed-at 50
• Within these hardware systems, there are 4
  different software options available
• A, B, C, and D (each level builds on the previous
  level)

emed-at software overview

• The following slides will give a brief overview
  of the emed-at software screens.
• Note refer to previous chart for features
  available in each software package

Data Acquisition

• This screen shows the data collection software
  just after data have been collected. The pressure
  picture with gait line (center of pressure) is
  shown on the left and the pressure, force, and
  area-time curves are shown on the right.

9
Data Acquisition
The icons along the top of the window allow the
file to be played dynamically or frame by frame.
There are fields to enter subject name and
comments.
10
Data Acquisition
It is possible to view the pressure, force, and
area-time information as line or bar graphs by
selecting the corresponding button.
11
Data Acquisition
This software also allows you to view the
actual pressure value of each sensor. You can
zoom in to better display the numbers. This is a
picture of frame 33 zoomed in on the first
metatarsal head and great toe. Also notice the
white dot on the gait line represents the center
of pressure for that frame.
12
Data Acquisition
Select the 3D icon to view the data as a 3D
pressure map.
13
Database Software
This screen shows the db-light software. Patient
information (top) can be stored along with data
files (bottom left) and additional comments
(bottom right).
14
Database Software
To make data collection and storage easy, the
patient information can first be entered and then
the emed-at software can be started directly from
the database. This will allow the data to be
directly linked to the patient. No further
organizational work is necessary! Simply select
the patient name, click on the start application
icon. Then select the program you want to start
(emed). The emed-at program will start. Once the
data are collected, the file will be saved and
linked to the database.

emed-st
16
emed-st system

• All emed-st systems have the same software and
  electronic box
• There is a choice between 2 different platforms
• emed-st 2
• emed-st 4
• The electronic box is used for signal processing
  and synchronisation with other systems
• The following screens will describe the different
  platforms and software features that build on the
  emed-at software

17
emed-st system overview
18
emed-st system overview

• Dynamic and static measurement
• Mode for automatic/manual storage of data files
• Integrated overview display for up to 10
  measurements
• Display of each frame in rollover process (ROP)
• Vertical force-time curve
• Maximum pressure-time curve
• Contact area-time curve

• Maximum pressure picture (MPP)
• Center of pressure display (COP) 2D and 3D
• Display of sensor value for each sensor
• 3D dynamic color display of ROP and MPP
• 11 print out of pressure picture
• Screen Copy
• Database DB light

19
emed-st software overview

• The following slides will give a brief overview
  of the emed-st software screens
• All features previously shown in the emed-at
  software are available in the emed-st software
• The following slides will show ADDITIONAL
  features

20
Data Acquisition

• This screen shows the data collection software
  just after several data files have been
  collected. The pressure picture with gait line
  (center of pressure) is shown on the left and the
  pressure, force, and area-time curves are shown
  in the middle. MPP pictures of each data file are
  shown on the right. Simply click on the thumbnail
  picture to view the corresponding file.

21
Data Acquisition
Select the 3D icon to view the data as a 3D
pressure map. The COP is superimposed over the 3D
picture. Use the navigation icons to play through
the file in the 3D view.
22
Data Acquisition
Data files can be automatically saved by
selecting the option automatically save measured
data. This will speed the process of data
collection.
