The Gross Motor Function Measure (GMFM) Self-Instructional Training CD-ROMs are designed to enable practitioners to train independently as reliable users of the printed Gross Motor Function Measure. They include details of the administration and scoring of all 88 items in the GMFM, as well as several video examples for each. Examples have been chosen to reflect a variety of scores and to highlight significant training principles. This CD-ROM set will be of interest to professionals using the GMFM for clinical or research purposes who want to gain a better understanding of the main testing, scoring and interpretation issues. The two CDs will take anywhere from 30 minutes to several hours to explore, depending on the user's purposes. The value of the system is the ability of the user to work through the program at their own pace and to return as needed to items previously viewed.
