two steps forward two steps back

Since the advent of his epilepsy diagnosis Calvin has made little progress in terms of his ability to walk. His awareness of objects—which to avoid and how—is better, but constant dizziness and gait ataxia, likely caused by high doses of his three antiepileptic medications, impede his progress to the extent that he isn't walking much better—perhaps even worse—than when he was three years old. Unfortunately for all of us it's two steps forward, two steps back.
