Frequently Asked Questions
- What do I do if I have an earlier version of the GMAE-2 on my computer?
Once the new version is downloaded, you must select the previous database by going to file- open database in order to continue using your previous database.
- Who do we contact for support if it's needed?
If you have followed the steps outlined in the tutorial and are still experiencing difficulties, please fill out this form. Currently, there is no guaranteed support available for the GMAE-2 but we will try and respond or post responses on our FAQ page.
- Are there normally upgrades for the application? If yes, how will upgrades be communicated to the users?
There are no regular updates planned at this time. GMAE-2 is provided as is. We do suggest you register when you download the software so we may send you an email in the event there is an update.
- Will the GMAE-2 run on a Mac? On a network?
Yes! The GMAE-2 is compatible on both a MAC and a PC but you must have the recent version of JAVA downloaded. The program can also be downloaded and used on a network.
- Is it possible to store data on a network server?
Yes, it is possible to store the data file on a network server, if it is connected as a drive to your computer however only one person can access the database at a time.
- How do we order the GMFM manual?
It is important to purchase the Gross Motor Function Measure (GMFM-66 and GMFM-88) User's Manual before downloading the GMAE-2 program. This manual contains important information on administering, scoring and interpreting the results of the GMFM. In addition, the manual provides information on the development and testing of the GMFM. The Users' Manual can be ordered through Wiley Blackwell Publishing and will be available in October 2013. Cost information is available from the publisher.
- Is an app available for the GMAE so it can run on a tablet?
Currently, we do not have an 'app' available for the GMAE.
- Are there any license or use restrictions?
Yes, you cannot sell this software, or make it available for distribution. For more information, please read the license before downloading the GMAE-2.
- Is there a function to audit (who inputs data, accesses data, etc.)?
No, there is no function available to audit the use of the GMAE-2 software.
- Is the data encrypted?
No, the data is not encrypted. It is strongly recommended that the end-user take all precautions possible to ensure confidentiality of data, i.e. use encrypted USB flash drives, secure access to computer on which GMAE-2 is installed
- Can I load data from the original GMAE into the GMAE-2?
Yes, the GMAE-2 has the ability to upload data from the original GMAE program. For more information on how to transfer data, please visit the tutorial.
- Is there a cost associated with purchasing this software?
The GMAE 1 version is no longer under any development or support plans. The GMAE 2 is openly available for download from our website, but users are strongly encouraged to purchase the manual in order to learn proper administration and scoring.
- Are there any support costs (one-time or yearly, etc.)?
The program is provided as-is. CanChild or McMaster does not guarantee any support, however users encountering issues are encouraged to fill out this form. Currently, there is no guaranteed support available for the GMAE-2 but we will try and respond or post responses on our FAQ page.

The GMAE-2 is a software package for scoring the Gross Motor Function Measure (GMFM). Like the original, it provides an interval-level measure of gross motor function based on a child's score on the items of the GMFM. Because the GMAE was calibrated on a sample of children with Cerebral Palsy, it is valid only for this population and should not be used with other populations of children (Down Syndrome, acquired brain injury, etc.).
The GMAE is made available for downloading on this page. If you appreciate these and other CanChild resources please consider donating to CanChild:
