Watch her left hand, she’s not holding on. He is holdeing her arm tightly. There is something wrong with her left side, same side her foot slips. She throws her sandals because she’s pissed.
You’re right, watching her left arm/hand makes me think stroke.
This is my observation, as well.
She is being held by her left side, and she cannot negotiate stairs on her left side.
I would feel sorry for her if she had chosen to not LIE about her health (but then, she lies about everything; she lies when the truth would have served her better; she lies to herself about why she lost the election.)

You are right...something is wrong with her left hand.
