Gesture imitation with lower limbs following left hemisphere stroke.
Ideomotor apraxia (IMA) of lower limbs has rarely been investigated systematically. This is the aim of the current study. Thirty-five patients with a unilateral stroke in the left hemisphere were tested within 30 days from onset with an upper limb IMA test and with a newly devised test assessing leg IMA. Seventeen patients presented with arm apraxia, six of them also showed severe leg apraxia. Results suggest that IMA of lower limbs emerges in association with severe arm IMA in patients with large lesions, and is a sign of general severity of the patient's conditions.
