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 areatime curves are shown on
the right.

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.

Data Acquisition
It is possible to view the
pressure, force, and areatime information as line or
bar graphs by selecting
the corresponding button.

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.

the data as a 3D pressure
map.

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).

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 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

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.

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.

Data Acquisition
Data files can be
automatically saved by
selecting the option
‘automatically save
measured data’. This will
speed the process of data
collection.
