Prevalence of apraxia among patients with a first left hemisphere stroke in rehabilitation centres and nursing homes

Objective: To investigate the prevalence of apraxia in patients with a first left hemisphere stroke. Subjects: Left hemisphere stroke patients staying at an inpatient care unit of a rehabilitation centre or nursing home and receiving occupational therapy (n = 600). Measures: A short questionnaire on general patient characteristics and stroke-related aspects was completed by occupational therapists for every left hemisphere stroke patient they treated. A diagnosis of apraxia or nonapraxia was made in every patient, on the basis of a set of clinical criteria. Results: The prevalence of apraxia among 492 first left hemisphere stroke patients in rehabilitation centres was 28% (96/338) and in nursing homes 37% (57/154). No relationship was found between the prevalence of apraxia and age, gender or type of stroke (haemorrhage or infarct). Conclusions: This study shows that approximately one-third of left hemisphere stroke patients has apraxia.
