Association of ideomotor apraxia with lesion site, etiology, neglect, and functional independence in patients with first ever stroke.

Ideomotor apraxia (IMA) is characterized by the inability to correctly imitate hand gestures and voluntarily pantomime tool use. The relationship between IMA and characteristics of stroke has not been totally elucidated.

This study aimed to find out associations between presence of IMA and stroke etiology, site of the lesions, neglect, and temporal and functional parameters of stroke in patients with first ever stroke.

Thirty-nine patients with first ever stroke were included. Patients with severe cognitive deficits were excluded. Assessment tools included Ideomotor Apraxia Test, Functional Independence Measure (FIM), Brunnstrom recovery stages, Mini Mental Test (MMT), and star cancellation test. Etiology (hemorrhagic or ischemic) and site of stroke was assessed through brain imaging methods. Location and size of ischemic lesion was determined by using the Oxfordshire Community Stroke Project system.

IMA was identified in 35.9% of the patients. Patients with IMA had significantly lower FIM scores both on admission and discharge (P = 0.001, P = 0.001). Presence of IMA was significantly associated with the presence of neglect (P = 0.004), total anterior circulation ischemia (TACI) (P < 0.001), and lower MMT scores (P < 0.001). Lesion site, patient age, time since onset, and stroke etiology had no impact on the presence of IMA.

IMA was in concordance with poor cognitive and functional state and was not limited to left hemisphere lesions. The study revealed strong associations between IMA, neglect, and TACI. Every patient with stroke should be evaluated for the presence of IMA on admission to rehabilitation unit.
