Whether the arrest was appropriate in the first place, and whether they paid attention to the mother explaining her daughter's disabilities, are entirely different questions.)
In this video at frame time 0.05 to 0.14 the mother's leg is clear and presence of the medical boot is unmistakeable. This is a difference angle than I have seen before.
In a different video, sorry don't have the link, where the mother is seen sitting on the bench early in the event I believe she can be seen putting on the boot but I could be mistaken on that point, just going from memory.
