Seeking expert counseling is a sign of strength. A personal relationship with a caring professional is proven clinically effective.
I believe that I can help.
You have, in most likelihood, correctly identified this woman as having Asperger's Disorder. Her lack of communication, her social anxiety, her lack of empathy (for injured coworker), her lack of focus (needing instructions to be repeated) and her gait and posture are all tell-tale symptoms.
Gait abnormalities have been widely reported in individuals with autism and Asperger's disorder. Furthermore they show abnormal arm posturing. These odd movements and postures are associated with the basal-ganglia frontostriatal region of the cerebellum.
I hope that this answers your question. If you have any follow up questions please feel free to get back to me.
Another clue may be the difficulty of making eye contact which is often but not always the case. She could be high-functioning and very intelligent but still have this disorder.
