“…Partial and elementary actions were maintained, but there were various errors in the movements he appeared to perform correctly. In the present study, five types of 10 patterns of errors were identified, based on two classifications by De Renzi and Lucchelli [6]and Hayakawa et al [10](table 2). First, he made errors in the relation between a hand and a tool.…”

“…De Renzi and Lucchelli [6]reported that in 20 left-brain-damaged patients performance in the single-object test was highly correlated with that in the multiple-object test. Recently Yamadori [9]and his colleagues have proposed the descriptive term of ‘apraxia of single-tool use’, based on their encounter with a rare case in which the ability to demonstrate the use of a single tool was disproportionally impaired [10]. Nevertheless, there have been few analyses of single-tool use.…”

“…They analyzed the multiple-object tests according to De Renzi and Lucchelli [6]but did not analyze the error patterns in the single-object test. The following 4 aspects which were proposed by Hayakawa et al [10]are the first criteria to analyze errors in single-tool use tests: the part of a tool the patient held, his/her way of holding it, the locus of the target where he/she applied it and his/her way of its manipulation.…”

Although disorders in the use of single objects have been reported, there have been few detailed analyses. We describe the autopsy case of a 65-year-old, right-handed male patient with severe impairment of actual tool use which was caused by biparietal infarctions. He persistently and stably showed a severely defective use of actual objects, single or multiple, and relatively well-preserved pantomimes of object use and intransitive gestures. He did not have aphasia or dementia, and his ability for tool naming and function description was completely preserved. The author identified similar patterns of errors about a tool-action(-target) relationship both in single-object use and multiple-object use. Lesion analysis showed cortical infarcts mainly located in the bilateral inferior parietal lobules, extending into the temporal lobe on the right side.

Apraxia is thought to reflect a disruption to high-level perceptual, cognitive and motor systems that form a distributed praxis network. Some authors suggest that apraxic deficits are unique to the neurology clinic; however, mounting evidence suggests that apraxic deficits are observable in natural contexts (e.g. Foundas et al., 1995). Naturalistic gesture production involves the integration of conceptual knowledge, gesture ideation, visual and somatosensory cues, and executive processes. Impairments in this context are therefore of interest from a clinical and theoretical standpoint. We present the case of a young female stroke patient (CK) demonstrating a novel limb praxis profile. CK's conceptual, evocation and praxis executive stages were evaluated: performance was contrasted to 30 healthy controls. CK was able to pantomime and imitate transitive gestures, suggesting that her ideational, executive and visual analytic systems were intact. Moreover, CK showed a good conceptual understanding of tools, objects and actions. However, CK demonstrated poor gesture production when actually using the tool associated with the action--a chronic and bilateral deficit that persisted at a 5-year follow-up assessment. Thus, CK's deficit appears to represent a specific and chronic disruption to high-level praxis systems that incorporates tactile inputs into the unfolding gesture production sequence.
