The combination of "stairs, chairs, and hair" symtoms of proximal myopathy, dermatologic symptoms (rash) and positive antinuclear antibody (ANA) makes dermatomyositis the most likely diagnosis [FA2020 p471].
The other autoimmune conditions listed (which could be associated with ANA) are not likely to have the same muscular involvement. Myscular dystrophy does not have dermatologic involvement or ANA+.
