I search about tools about disability in moodle and how enable or download ,
i review accessibility block but it is not useful .
i find letter about tools enable users to control it in profile.
I don't really know of specific tools for disabilities in Moodle. Perhaps you could tell us what type of disability you want to accommodate and we might be able to come up with ideas and methods of using Moodle that might work for what you need.
Moodle should not require specific disability tools. Users with a disability should be able to access Moodle using the same assistive technologies that they use to access other web sites.
