I have downloaded some apps illustrating sign language from the Android play store, but I have something remotely related to muscular dystrophy.
Is fitness of the arms and hands and face muscles a prerequisite for doing sign language? What if one cannot due to fatigue, sickle cell anemia, or ano other drug-induced or other tiredness condition?
Thanks.
(Also, why are the [face] and [mouth] tags missing from the list of tag choices)?
