The temperature change rate
The number of subjects which the normative data statistics is
based on.
The average threshold of the subjects that were tested to
collect the specified normative data.
The standard deviation of the threshold of a sample subject who
was tested to collect the specified normative data.
The upper limit as calculated from the normative data.
Upper Limit = AVG + 2xSTD.
The lower limit as calculated from the normative data.
Lower Limit = AVG – 2xSTD.
Thermode size used to collect this Normative Data (30x30,
16x16, …)
Note: In order to apply the normative data to test results, it is necessary to provide the upper
limit for Warm Detection Threshold and Heat Pain or the lower limit for Cold Detection
Threshold and Cold Pain. However, if these parameters are left blank, the software will
calculated them from the average and standard deviation. In this case of course, the average
and standard deviation must be provided instead.
The following operations are available:
Export or import a list of normative data – The list of normative data can be exported
or imported from a excel file. To see the required configuration of the excel file required for
import, export the manufacturer normative data list and use the same format. The user
normative data list can also be exported and important as an *.ats file for backup.
Add or remove data from the list of User Normative Data – add, edit or remove
normative data from the user normative data list.
To add new normative data to the list:
1. Click the New button to add a new row to the User Normative Data table
2. Enter the details for the normative data (for information about the specific parameters see
Table 33 above)
3. Click the New button to add more rows or Apply to save and apply the new data.
12.4 Selecting Normative Data Source
The built-in Normative Data includes several normative data tables from different sources.
Each Normative Data table is usually based on a different publication. The normative data
tables may differ in age groups, body sites and even in normative values for same gender, age
group and body site. Before using the built-in normative data select the source of the data
which best fit your application.
To select a Normative Data table following the instructions below:
1. Open the Normative Data editor: select Utilities from the top menu bar, and then
select Normative Data.
2. Click the arrow to right of the data source name. A list will open displaying the list of
available sources.
