According to YouTube user Rumurril, the girl in the wheelchair was suffering from unexplained paralysis, then she just as mysteriously regained her ability to walk.
Our daughter, Bailey, had complete paralysis from the waist down for 11 days with no explanation as to why. This video is of one of her favorite nurses coming onto her shift and not knowing that Bailey had started walking this day.
Nurses get a chance to interact more intimately with patients than doctors do. This is a very moving scene and illustrates the level of compassion that nurses show.
