Abstract

Aim: This study aimed to examine the effect of clinical factors including side of stroke, region of affected cerebral circulation, type of stroke and time since stroke, as well as age on the number and type of impairments of visual perception and praxis in patients following stroke.

Methods: Two hundred and eight participants with stroke were conveniently sampled from 12 hospitals in Brisbane and the Gold Coast. Background information was collected and each participant was assessed for impairments of visual perception and praxis using the Occupational Therapy Adult Perceptual Screening Test.

Results: Participants with left‐hemisphere stroke were more likely to have impaired body scheme than participants with right‐hemisphere stroke. Additionally, participants with right‐hemisphere stroke were more likely to have unilateral neglect and impaired constructional skills than those with left‐hemisphere stroke. There was a significant relationship between region of affected cerebral circulation and the occurrence of agnosia, unilateral neglect and constructional skill impairment. Moreover, the number of visual perceptual impairments experienced by participants was associated with the region of affected cerebral circulation. Increasing age was significantly related to the occurrence of constructional skill impairment and acalculia.

Conclusions: Side of stroke, region of affected cerebral circulation and age affected the type of impairments of visual perception and praxis experienced by patients following stroke. Furthermore, region of affected cerebral circulation also influenced the number of impairments of visual perception and praxis in patients after stroke. The results have implications for more specific targeting of assessment and treatment practices following stroke.
