The significance of clumsy gestures in apraxia following a left hemisphere stroke

摘要: Individuals who sustain a cerebrovascular accident (CVA) in the dominant (typically left) hemisphere, are at increased risk of developing motor skill deficits due to motor-sensory impairments, as well cognitive impairments (e.g., apraxia). Clumsiness is central component affecting skills individuals with left hemisphere CVA (LCVA). The term "clumsiness" however, has not been adequately operationalised apraxia literature clinical terms, thereby making diagnosis difficult and its contribution apraxic disorders uncertain. Accordingly, this study was explicitly defined by establishing set four criteria. non-dominant (left) hand movements three groups participants were examined: 10 limb-apraxia (APX); 8 without limb had sustained LCVA (NAPX); 19 healthy history brain impairment (NBD). Performance examined on sets tasks, including conventional praxis test, basic perceptual-motor co-ordination fine movement naturalistic actions test. A striking finding that emerged clumsy errors occurred frequently all groups, NBD group, particularly tasks. In terms quantity emitted, APX group made significantly more gestures across tasks comparison group. No differences between two total emitted action or type Thus, frequency types partly determined task demands. These results highlight need consider functioning following hemispheric damage. broad these findings emphasise importance adopting detailed analyses assessments cognitive-based impairment.
