“…Based on the known involvement of the left posterior temporal cortex and inferior parietal lobe in tasks that engage action knowledge (e.g., Kellenbach et al, 2003;Weiss et al, 2008;Kalénine et al, 2010;Randerath et al, 2011), we predicted that the Posterior participants would perform differently than Anterior or Control participants on triads in which Action association is a determining feature, namely, the Th+A vs. Th-A triads. Thus, the Anterior group served as a neurologically-impaired control group, and its members' lesions did not include regions predicted to disrupt action knowledge (i.e., inferior parietal and posterior temporal cortex).…”

The Role of Action Representations in Thematic Object Relations

A number of studies have explored the role of associative/event-based (thematic) and categorical (taxonomic) relations in the organization of object representations. Recent evidence suggests that thematic information may be particularly important in determining relationships between manipulable artifacts. However, although sensorimotor information is on many accounts an important component of manipulable artifact representations, little is known about the role that action may play during the processing of semantic relationships (particularly thematic relationships) between multiple objects. In this study, we assessed healthy and left hemisphere stroke participants to explore three questions relevant to object relationship processing. First, we assessed whether participants tended to favor thematic relations including action (Th+A, e.g., wine bottle-corkscrew), thematic relationships without action (Th-A, e.g., wine bottle-cheese), or taxonomic relationships (Tax, e.g., wine bottle-water bottle) when choosing between them in an association judgment task with manipulable artifacts. Second, we assessed whether the underlying constructs of event relatedness, action relatedness, and categorical relatedness determined the choices that participants made. Third, we assessed the hypothesis that degraded action knowledge and/or damage to temporo-parietal cortex, a region of the brain associated with the representation of action knowledge, would reduce the influence of action on the choice task. Experiment 1 showed that explicit ratings of event, action, and categorical relatedness were differentially predictive of healthy participants' choices, with action relatedness determining choices between Th+A and Th-A associations above and beyond event and categorical ratings. Experiment 2 focused more specifically on these Th+A vs. Th-A choices and demonstrated that participants with left temporo-parietal lesions, a brain region known to be involved in sensorimotor processing, were less likely than controls and tended to be less likely than patients with lesions sparing that region to use action relatedness in determining their choices. These data indicate that action knowledge plays a critical role in processing of thematic relations for manipulable artifacts.

“…Eight different tools were presented, and the patients were requested to demonstrate their use. A detailed description of the test and the scoring system used can be found in Randerath et al (2009Randerath et al ( , 2011. As expected, LBD patients scored worse than RBD patients (LBD: mean = 71.05%, range: 0-100%, RBD: mean = 99.2%, range: 97-100%).…”

“…Their errors vary widely from severe errors, such as no movement response or unrecognizable movements, to milder errors, such as incorrect hand grips at the imagined tool. A number of studies reported that patients perform better when they are allowed to actually use tools as compared to when they pantomime tool use (Buxbaum et al 2000;Clark et al 1994;De Renzi 1990;Goldenberg and Hagmann 1998;Goldenberg et al 2004;Hermsdörfer et al 2006;Laimgruber et al 2005;Liepmann 1908;Wada et al 1999), although errors or even inability of actual tool use have also been reported (De Renzi and Luchelli 1988;Goldenberg and Hagmann 1998;Goldenberg and Spatt 2009;Westwood et al 2001;Randerath et al 2011). In one of these studies (Goldenberg et al 2004), a neutral wooden implement resembling the handle of the tools was provided instead of the real tool (i.e., a 10-cm-long stick with a diameter of 3 cm instead of the hammer).…”

“…The hammering task studied by Randerath et al (2011) was also subjected to kinematic analyses . This study revealed a partial independence of apraxic pantomime errors as revealed by video analyses from kinematic movement abnormalities, suggesting that more conceptual apraxic errors may be dissociable from deficits in movement programing.…”

“…In addition, the fast hitting movement is largely open-loop. In order to analyze the role of task characteristics in our previous findings, we performed kinematic analyses of the scooping task that was also used by Randerath et al (2011). This study compared apraxic errors between tasks as assessed by video scoring, while the present kinematic approach allows for objective comparisons of performance aspects that are not limited to errors.…”

Movement goals and task mechanics differ substantially between actual tool use and corresponding pantomimes. In addition, apraxia seems to be more severe during pantomime than during actual tool use. Comparisons of these two modes of action execution using quantitative methods of movement analyses are rare. In the present study, repetitive scooping movements with a ladle from a bowl into a plate were recorded and movement kinematics was analyzed. Brain-damaged patients using their ipsilesional hand and healthy control subjects were tested in three conditions: pantomime, demonstration with the tool only, and actual use in the normal context. Analysis of the hand trajectories during the transport component revealed clear differences between the tasks, such as slower actual use and moderate deficits in patients with left brain damage (LBD). LBD patients were particularly impaired in the scooping component: LBD patients with apraxia exhibited reduced hand rotation at the bowl and the plate. The deficit was most obvious during pantomime but actual use was also affected, and reduced hand rotation was consistent across conditions as indicated by strong pair-wise correlations between task conditions. In healthy control subjects, correlations between movement parameters were most evident between the pantomime and demonstration conditions but weak in correlation pairs involving actual use. From these findings and published neuroimaging evidence, we conclude that for a specific tool-use action, common motor schemas are activated but are adjusted and modified according to the actual task constraints and demands. An apraxic LBD individual can show a deficit across all three action conditions, but the severity can differ substantially between conditions.

Apraxia is defined as the difficulty or inability to perform learned skilled actions. Identifying apraxia in patients has prognostic implications. The praxis network is predominantly in the left hemisphere, and comprises parietal lobe regions that connect to several circuits involving the frontal, temporal and occipital cortices and the basal ganglia. This review discusses the types of apraxia and the disorders associated with apraxia, highlighting studies based on corticobasal syndrome and stroke as disease models. The evolution of historical concepts of praxis leading up to the current ‘pathway’ models is discussed in the context of neuroanatomical and imaging studies. Bedside testing and interpretation of apraxia are elucidated with examples. Key Concepts Apraxia is the difficulty in performing acquired actions and can be seen independent of other symbol‐mediated disorders such as aphasia. Apraxia is associated with several neurodegenerative disorders such as corticobasal syndrome, as well as with strokes and head trauma. There are several different forms of apraxia such as ideomotor, ideational and orofacial apraxia, and each is characterised by the specific manner in which action performance or interpretation is compromised. The praxis network involves circuits from frontal, temporal and parietal cortices and the basal ganglia. Left parietal lobe is pivotal for the praxis network. Newer models of praxis propose bilaterally represented ventral and dorsal processing streams, with the dorsal stream further subdivided into dorso‐dorsal and ventrodorsal substreams. The dorso‐dorsal or the ‘grasp’ system processes characteristics of a tool such as size, shape and orientation, while the ventrodorsal or the ‘use’ system stores object‐specific actions. In patients with left hemisphere damage, apraxia often coexists with aphasia; in patients with right hemisphere lesions, apraxia is often associated with a visuospatial disorder. Testing of apraxia at bedside is important for diagnostic and prognostic reasons.
