What are the significant differences between athetosis and ataxia?

A) Fluctuating or uneven muscle tone characterizes athetosis; a lack of motor coordination with poor balance and a lurching walk characterizes ataxia.
B) A lack of motor coordination with poor balance and a lurching walk characterizes athetosis; fluctuating or uneven muscle tone characterizes ataxia.
C) Children with athetosis may have great difficulty with fine motor activities such as feeding themselves, writing, cutting with scissors, and picking up small objects; children with ataxia tend to retain primitive reflexes such as grasping and sucking past the normal time.
D) Involuntary movements resulting in materials being dropped or pushed off the table are particular to athetosis; the retention of primitive reflexes of children with ataxia affects the development of voluntary motor responses.
