I emailed Ad a few years ago.
On the second link you can send him a message. It would be great if you could contact him - he is a really nice guy.
For the section in Galicia, you can use the resources of Cogami:
COGAMI (La Confederación Gallega de Personas con Discapacidad)
This site has a lot (hundreds!) of photos for the stages between O Cebreiro and Santiago on the
Camino Frances. If you are in a wheelchair, you will see what type of road/surface you can expect plus sections that might be difficult. The site is only in Spanish and Gallego. The photos and text have been collected/ written by people at COGAMI (La Confederación Gallega de Personas con Discapacidad) who have a lot of experience with this type of material.

Also, in 2004 Ibermutuar (a Spanish mutual insurance conglomerate), together with several Spanish charity organisations and companies, sponsored a guide aimed at pilgrims with restricted mobility. Three pilgrims that covered the
Camino Frances in wheelchairs participated directly in the preparation of the guide. The site is in Spanish but you can copy the link into an online translator to convert it to your language.
It breaks each day into small sections of 8 km per day and describes how easy/difficult they are with distances, facilities such as banks and shops, which towns offer repairs and more importantly, on which parts of the route you might need assistance. There is also information about the pilgrim credential and obtaining the Compostela.
An outline of the guide
The advice, suggestions, alternatives and remarks are the result of hours of efforts during the tour, which gives a look at the difficulties that face disabled pilgrims. The daily stages are not those suggested in other guides because it was considered that a person with disabilities would find it difficult to follow a pace of 25–30 km per day.
Each stage is described according to the original path, with alternatives for people with reduced mobility where, due to its difficulty, it must be separated from the ancient route. The difficulties described in the different stages refer to those found by a disabled person in a wheelchair, with a reduced physical strength. It also outlines cultural sites, entertainment, basic services in localities where the stage ends and accommodation, describing their conditions of accessibility.
