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.

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.
April 2002 novel emed systems novelgmbh © 2002
Data Acquisition
It is possible to view the pressure, force, and area-time information as line or bar graphs by selecting the corresponding button.
April 2002 novel emed systems novelgmbh © 2002
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.

Data Acquisition
Select the 3D icon to view 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).
April 2002 novel emed systems novelgmbh © 2002
Database SoftwareTo 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
April 2002 novel emed systems novelgmbh © 2002
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 AcquisitionThis 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.
April 2002 novel emed systems novelgmbh © 2002
Data Acquisition
Data files can be automatically saved by selecting the option ‘automatically save measured data’. This will speed the process of data collection.
