Cross Neuro Database


Each EMG system stores its data in its own format, unreadable by standard programs, such as the Microsoft Office programs.

The Cross Neuro Database program has an automatic Import function that scans your EMG systems data files and imports data, and for some systems also curves, into a SQLite, MySQL or MS-SQL database.

Once in the database, data extraction, statistics and result presentation possibilities are almost unlimited.
The built-in Data Mining features (search and filter) presents extracted data, curves and graphs in MS-Excel® and MS-PowerPoint®.

Supported EMG systems

Cross Neuro Database is compatible with the following EMG systems:
  • Keypoint®Net
  • Keypoint®Classic

Imported Data

The following data is Imported:


  • Patient Data including Comments fields
  • Motor Sites and Segments. Note: MNCS Tests marked as "Separate Test" are NOT imported.
  • Sensory Sites and fSegments. Note: SNCS Tests marked as "Separate Test" are NOT imported.
  • F-Wave Summary Data. Note: Individual F-Wave data are NOT imported.

  • Clear Database before Import: All data in the database will be cleared before a new Import starts. If not selected, the database will be updated with new and updated studies.
  • Delete studies in the database that are deleted in the EMG System: Check to have a full synchronization between the Cross Neuro Database and the EMG systems database.

Prepare for Keypoint®Net Import

To Import Keypoint®Net data a few steps are required:

(1) The 'Keypoint.Net Integration Service' (KPIS) and 'Keypoint.Net Service' must be installed and running on the computer where the Cross Neuro Database application is running.
To check that:
- Right click on the Win-key (lower left flag) icon
- Select Task Manager - Services

If any of these services are not running, follow these steps:

- Right click on the Win-key (lower left flag) icon
- Select Computer Management
- Expand 'Services and Applications'
- Select Services
- Right Click on 'KeypointNET Integration Service' and select Properties
- Set Startup Type to 'Automatic (Delayed)'
- Click Start, Apply, OK
- Repeat the procedure for the 'KeypointNET service' if necessary.
- Close all windows

(2) The Keypoint®Net report template 'CrossNeuroDatabase' must be installed:
- Start Keypoint®Net
- Enter 'Options' - 'System' - 'Reports'
- Right click in the upper left report template area and select 'Import'
- Select the file 'C:\Users\< user >\My Documents\CrossNeuroDatabase\System\crossceurodatabase.wrs'
- Exit Keypoint®Net

(3) Change check-in mode. NOTE: Only necessary if Keypoint Datacenter (network server) is used.
- Start the 'Keypoint Admin Tool' program as an Administrator (right click on the desktop icon and selecxt 'Run as administrator').
- Select Networking
- Change Network check in mode to: 'Use Keypoint.Net Service' (2.40) or 'Use KPIS' (2.32).

- Exit
- Restart the computer.

CrossNeuroDatabase can now be started and perform an Import of Keypoint®Net data.


If multiple databases are Active (see Database Setup), select the database to be used. The last used database will be selected by default.
Local MySQL database: enter the "Root password" as inserted during MySQL installation.
Remote MySQL database: enter the "User password" as inserted during MySQL installation.
Local or remote MS-SQL database: enter the password set during MS-SQL database configuration. This field is not seen if a trusted connection is established, i.e. no password is used.
SQLite database: password protection is not used.
Insert password, if required, and click [Login] to continue. Click [Setup] to access the Database Setup.

After successful login, the main menu is seen:

To logout, switch database or edit settings, click [Logout] or exit and restart the Cross Neuro Database program.

Import Data

The Import function reads data from the EMG System(s) and places the results in currently selected database.
Data and curves (if selected) are imported into the database tables, one per test type.

Click [Import] followed by [Start Import] to import data from all data sources defined in Setup.
A log is kept for the last Import process. Click [Last Import Log] to view the log.
During Import, temporary files are created in C:\users\<user>\Cross Neuro database\Temp.
The Temp folder must have at least 4GB free space if both Data and Curves are Imported, and 2GB if only data is imported.
Keypoint®Classic: Verify in the config.xml file that correct Code Page is specified. Find and edit the item 'importCodePage'.

Import running:

Import usually takes a long time (hours), depending on number of studies and computer performance.
Excluding curves (see Setup), significantly reduces the total import time.
Uncheck 'Clear database before Import' in Setup to only Import studies added since last Import.

All data are now saved inside the database and ready to be processed by Data Mining features.

Do not delete the original EMG System data!
It is likely that the database needs to be refreshed by future versions and the data files are required at each Import procedure.

Patient Review

  • Select Patient Review from the main menu.
  • Insert patient ID.
  • Note: Patient Review doesn't work with an Anonymous database since Patient ID is not available.
  • All visits found for the patient are listed.
  • Select result options.
    • Summary Data = An Excel sheet with selected parameters from selected data tables for all visits.
      Tables and parameters are selected using [Setup].
    • Detailed Data = One Excel sheet per data table. All parameters from all visits.
    • Curves = A Powerpoint presentation with selected curves.
      Included curve types are selected using [Setup].
      Select resolution of curves.
      • High resolution: all samples.
      • Standard resolution: plots every Nth sample depending on curve type.
  • Select Setup to change content of output.

    • Click on a Data table to view selected parameters.
    • Use the control buttons to add, deselect and position selected tables and parameters.
    • The layout is saved when pressing OK.

  • The displayed results are overwritten next time you do a Patient Review.
    Use 'Save As' in Excel and PowerPoint to save files permanently.

Summary Data presented in an Excel sheet:

Detailed Data presented in one Excel sheet per type:

This table layout allows follow up on one or multiple parameters for a selected patient.

This is how to do it:
  • Select datatable using the bottom tabs.
  • Filter the nerve, side etc. to be included in the follow up using the arrow in the field header.
  • Select the entire Study Date column (click on the header letter).
  • Select parameter(s) to monitor by holding the keyboard Ctrl-button down while clicking on the parameters column header letter.
  • Select Insert-Line chart

An example:

Curves in a Powerpoint presentation: (Note: curves not available for Keypoint.Net studies)

Curves of same type are drawn with same X and Y scales to allow graphical comparison (eg. superimpose).
Use Powerpoints rescale features to resize individual curves.

Data Mining

Select Data Mining in the Analysis window from the main menu.

(1) Select Studies
As the first step of the Data Mining process, insert filtering details for the studies to be extracted. Number of studies found in the database, matching the inserted filters are shown on the last line. Wildcards (*=any text and ?=any character) may be used for text fields (Technician, Physician, Diagnosis). E.g. Diagnosis = 'N35*' will select both N351 and N35678. Diagnosis = 'P3?X' selects all 'P31X' and 'P32X'.

Link File selects the studies listed in a text-file.
The file may consist of either Study ID's, Patient ID's or Study Keys.
Inserting Patient ID will select all studies for the specified patient.
Create a text file (e.g. using Notepad) and enter one number per row.
Save the Link files in \MyDocuments\Cross Neuro Database\LinkFiles.
Click on […] and select the text file.
Select contents of the file. A warning will be given if any errors are found. Duplicate numbers will only be included once.

The study identification fields are used as follows:
Study ID: Study identification number. Manually inserted in Keypoint®Net. Sequential Keypoint number (without zeros) used in Keypoint®Classic.
Patient ID: Patient identification. Same for all studies for each patient.
Study Key: Unique, internal GUID value created for each study by Cross Neuro Database. This value may be updated by the Import function.
Patients matching current filter can be reviewed in Excel.

Click the green right arrow at the top (Next) when the patient group is selected.

(2) Select Data

Each test type is stored in a ‘table’ inside the database. One parameter per column and one recording per row. Take a look at the MNCS Sites table as one example:

Curves are stored in tables as well, with one curve per row and each sample value per column. Like this:

Similar tables are created during Import in the database for each test type. Some tests are divided in to several tables, e.g. MNCS Sites, MNCS Segments. There are in total 32 data tables, 21 curve tables and one Study table. The field ‘Study Nr’ is available in all tables. It is unique for each study and used to connect all tables and link information belonging to the same study.

Extracting data and curves using the Data Mining features are divided into three output structures:
  • Data Parameters
  • Data Parameters - Merged
  • Curves (Keypoint®Classic only)

Select Data Parameters
Output will have same format as the database table, but with possibility to select/exclude parameter columns. This type shall be used to analyse parameter(s) for one test type, e.g. MNCS Median Distal Latency. Anatomies (nerves/sites, muscles) will be placed under each other.

Left column:
  • Select Table type
  • Specify the anatomy filter settings. Leaving a field empty or *ALL* means no filter. All table rows matching the filter will be extracted.
  • Click [Add] to save the filter.

Right Column:
  • Topmost section shows all added data table types.
  • The section below shows all anatomy filters for the selected table type.
  • Select parameters for each table type to be included in the output.
  • Select additional patient data fields to be added to the output.
  • To save time, use [Save Setup] to save current filter settings and [Load Setup] to load previously saved settings.

Click the green right arrow to Start Extraction (see below)

An example of a Data Parameters table:

Select Data Parameters – Merged

Output will be one merged table, with columns extracted from one or multiple database tables. This allows comparison of for example MNCS Site with an EMG parameters recorded on the same patient. This type shall also be used when comparing parameters from the same table, but different anatomies. E.g. MNCS Left Motor Median Wrist-APB Latency --- MNCS Left Motor Ulnar Above Elbow – ADM Latency.

Left column:
  • Select Table type
  • Specify the anatomy filter settings.
  • All fields must be inserted.
  • All table rows matching the filter will be extracted.
  • Select parameter(s) to be included. Click [Add] to save the filter.

Right Column:
  • Topmost section shows all added parameters. Each parameter will result in one column in the output file.
  • Use control buttons to delete and rearrange the parameters/columns.
  • Select Keep rows filter rules.
    • Data in all columns: Only rows with data in all columns will be included.
    • Data in any column: rows with data in any column will be included. Fields with missing data will be grayed in the output file.
    • No data: include all rows for selected patients, even if no measurement data is available. This mode is useful when merging output result files to get data from the same patient on the same row.
  • Select additional patient data fields to be added to the output.
  • To save time, use [Save Setup] to save current filter settings and [Load Setup] to load previously saved settings.

Click the green right arrow to Start Extraction (see below)

Below is an example of a Merged Data table. Grayed field indicates that no data were recorded for the patient/parameter.

Select Curves

Output will be curves from one or multiple test types.

Left column:
  • Select Table type
  • Specify the anatomy filter settings.
    Leaving a field empty or *ALL* means no filter.
    All table rows matching the filter will be extracted.
  • Click [Add] to save the filter.

Right Column:
  • Topmost section shows all added data table types.
  • The section below shows all anatomy filters for the selected table type.
  • Select parameters for each table type to be included in the output.
  • Select additional patient data fields to be added to the output.
  • Select output format
  • To save time, use [Save Setup] to save current filter settings and [Load Setup] to load previously saved settings.

Click the green right arrow to Start Extraction (see below)

An example of MS-PowerPoint output:

Sample values are saved in uV in MS-Excel output:

Start Extraction
Click [Start], insert a project name and click [OK] to start the Extraction. The project name will be used as the folder name where all result files will be saved. The default location for output results is: \MyDocuments\Cross Neuro Database\Results.

When the Extraction is completed, Windows Explorer will be displayed showing the result folder. Double click on the result files to review the result. If sensitive patient data is included in the resulting file, such as ID or name, the file will be password protected. The same password as for the database/login will be used. To change it, please read about passwords for Excel file on the Internet. A ReadMe.txt file is created and saved in the output folder. It contains information about which filter criteria etc. that was used for the extraction.

Production Statistics

Select Production Statistics in the Analysis window from the main menu.

Click [Start] and select result output folder.

Detailed numerical results for patient and test statistics are saved on sheets 3 (Patient Data) and 4 (Test Data). On sheet 1 (Patient Summary) and sheet 2 (Test Summary), Pivot tables and Charts are created automatically. The Pivot table function in MS-Excel is very powerful and gives large possibilities to display and format data in various ways. Please read more about “Excel Pivot tables” on the Internet.
A few examples are shown below.

Number of patients per year over many years:

Number of patients per month for a selected year:

Total number of tests (EMG’s, MNCS’s….) over many years:

Total number of EMG’s over many years:

20 most commonly studied muscles:

Patient Integrity

Patient integrity has high priority in a medical database system. To address this subject and maximize integrity while still have the required analysis features, the Cross Neuro Database has the following security/integrity features:
  • Database password For a local database, define the password in Database Setup. For a remote server database, contact your IT-administrator.
  • Automatic logout Specify the logout time under Options-Autologout Time.
  • Anonymous Import Activate under Options-Anonymous. Patient name and ID will be excluded during the Import procedure. I.e. not physically available in the database. Patient name and Patient ID are set to blank.
  • Anonymous Data Mining The output from Data Mining will never include Patient Name or ID in resulting MS-Excel® and MS-Powerpoint® files.
  • Patient Filter Data Mining does not allow filter on name or ID.
  • Patient Review Allows search on Patient ID, but will not include name or ID in any resulting files.
  • Logging All searches in Patient Review will be saved in a hidden log-table inside the database.
