You might try looking down when she needs to be looking down. Don't know where your hands, balance and body intentions are, but all of you focusing on that intention consistently and gently, with lots of encouragement may help. If your consistent and it seems to help, you can get more subtle with cues as time goes on and she'll probably have the confidence and self assurance by then.
You might try doing some massages, stretches, belly lifts etc. with her. If she's not fully aware of herself or is "somewhere else," sometimes massaging and stretching helps, and/or maybe spicing things up a bit with a break in routine. Another thing that crossed my mind is possible physiological discomfort causing her to "drag" herself over the poles.
