Doesn’t look out of the ordinary to me in that photo. According to Parkinson literature, hand tremors/issues occur when the hand is at rest. Notice she often puts her hand to her chest or clasps her hands when she doesn’t have a podium or microphone nearby. The right hand/arm is also worthy to watch besides the freezes..
She does see to have some of the parkinson’s side affects from medication....however the nature of the disease does say there are good days and bad days.......I believe possible why they “cycle” her events....
She just had a speech in N.c. followed with a very brief question period for reporters....I believe she was already feeling the bottoming out of the medication used to ramp her up as her eyes were bothering her and she was clearing her throat....she bailed early.
