This study investigates unawareness of apraxia (UA) after left-hemisphere stroke, finding that UA is common, linked to impaired action knowledge, and associated with reduced error correction attempts.

This study investigates whether mechanical reasoning is necessary for novel tool use in apraxia and finds it is not, suggesting tool use is more intuitive.

The paper investigates whether physical reasoning and tool use can dissociate in individuals with left-hemisphere brain damage, finding individual-level dissociations in task performance.

This study investigates whether combining gesture priming and neuromodulation improves verb retrieval in aphasia but finds no additive benefit, instead showing interaction effects.

This study investigates how tool-hand motion incongruence affects movement planning in individuals with limb apraxia, finding increased planning time for incongruent tools and linking impairments to specific brain lesions.

This study identifies praxis, attention, and language deficits as predictors of naturalistic action impairments in left hemisphere stroke patients.

This study investigates response selection mechanisms in tool and non-tool actions after left-hemisphere stroke, finding distinct neural substrates for grasp-use interference and response interference in different tasks.

This study investigates gesture imitation differences across PPA variants, finding that svPPA shows unique impairments in hand posture regardless of gesture meaning.

This study applies a visual attention training method to right hemisphere stroke patients, showing improved attention in some but not all participants with mild left inattention.

The paper identifies two subtypes of limb apraxia based on distinct neuroanatomic lesion profiles using structural MRI and graph analysis in stroke patients.

The paper investigates whether posture-based and trajectory-based imitation are distinct mechanisms by measuring imitation accuracy after different intervening tasks.

This study investigates the role of proprioception in imitation, finding that apraxia patients struggle more with proprioceptively cued movements than visually cued ones.

This study shows that retargeting of efferent projections to residual muscles in lower limb amputees is associated with increased phantom limb pain.

This study identifies predictors of arm non-use in chronic stroke patients, finding that attention/arousal and self-efficacy, along with motor impairment, predict non-use behavior.

The paper identifies structural disconnection patterns in the brain that predict severity of limb apraxia after left hemisphere stroke.

This study investigates tool action errors in left hemisphere stroke patients, finding reduced competition between tool actions in both grasp-on-use conflict and tool neighbor scenarios.

This study investigates how humans imitate movements by analyzing stroke patients' ability to replicate trajectories using different cues, finding that dorsal premotor cortex plays a key role in abstract trajectory representation.
