Imitating gesture learning in apraxic patients.

The authors studied a group of patients with ideomotor apraxia (IMA) to verify if these patients had some difficulties in gesture learning task in respect to non-apraxic patients and normal control subjects. The results show that learning difficulties are present in patients with IMA. Apraxic patients are not able to perform the gestures in the testing situation and non in everyday life; this fact would demonstrate that the motor pattern still exists in these patients but is inaccessible unless elicited by a strong stimulation.
