“…[ 17 , 18 ] A recent review suggested that rehabilitative training alone would be insufficient for a sustained benefit. [ 19 ] However, our patient showed significant recovery from apraxia 3 months after completion of our intervention. More studies and large-scale clinical trials are needed to determine the therapeutic efficacy and its mechanism in VR application for apraxia.…”

Rationale: We report the possible therapeutic efficacy of immersive virtual reality (VR) rehabilitation for the treatment of ideomotor apraxia in a patient with stroke. Patient concerns: A 56-year-old man with sudden weakness of his left side caused by right frontal, parietal, and corpus callosal infarction was transferred to rehabilitation medicine center for intensive rehabilitation. Although his left-sided weakness had almost subsided 10 days after the onset of symptoms, he presented difficulty using his left hand and required assistance in most activities of daily living. Diagnoses: Ideomotor apraxia in a patient with right hemispheric infarction. Interventions: VR content was displayed to the study participants using a head-mounted display that involved catching of moving fish in the sea by grasping. Before and after of rehabilitative intervention including VR, functional measurements incorporating the Test of Upper Limb Apraxia (TULIA) were conducted. To directly compare therapeutic potencies under different conditions, success rates of consecutive grasping gesture performance were observed in VR, conventional occupational therapy setting, and augmented reality intervention. Outcomes: The patient demonstrated remarkable amelioration of apraxic symptoms while performing the task in the VR environment. At 1 and 3 months after the training, he showed significant improvement in most functions, and the TULIA score increased to 176 from 121 at the initiation of therapy. The number of successful grasps during 30 trials of each grasp trial was 28 in VR, 8 in the occupational therapy setting, and 20 in augmented reality. Lessons: This case report suggests the possible therapeutic efficacy of immersive VR training as a rehabilitative measure for ideomotor apraxia.

“…Apraxia has been defined as the inability to carry out learned skilled motor acts despite the motor and sensory systems being intact with respect to coordination, comprehension and co-operation (Gross and Grossman, 2008;Heilman and Valenstein, 2003). Apraxia is seen in various neurological disorders, including stroke and neurodegenerative disorders, such as Alzheimer's disease, Parkinson's disease and atypical Parkinsonism, the latter of which includes corticobasal syndrome, multiple system atrophy and progressive supranuclear palsy (Park, 2017).…”

Background Apraxia has a major impact on activities of daily living in stroke patients. The proper assessment and treatment of apraxia is important for maintaining a good quality of life. We developed a short evaluation test for upper limb apraxia. Patients and Methods The present Screening Test of Gestures for Stroke consists of 10 items for each verbal instruction and imitation. Each item includes three meaningless gestures, three meaningful gestures and four pantomimes. The Screening Test of Gestures for Stroke is scored based on a 3-point system: 10, 5 or 0 (maximum score: 200). The test took approximately 2–5 min to complete. We recruited 65 patients admitted to our hospital with left hemisphere stroke and 50 healthy subjects. Results The reliability of the Screening Test of Gestures for Stroke was as follows: the intraclass correlation coefficient of intra-rater reliability was 0.93 for both verbal instructions and imitations, and the intraclass correlation coefficient total scores for inter-rater reliability for verbal instructions and for imitations were 0.97 and 0.95, respectively. The alpha coefficient was ≥0.80. Conclusions The Screening Test of Gestures for Stroke is a reliable and valid bedside test that has a short assessment time, does not require special equipment and can evaluate upper limb apraxia in stroke patients from the acute to the chronic phase.

“…Deficits in praxis functions can have obstructive effects on the activities of daily living and can significantly impair the patients' ability to live autonomously (Dovern et al, 2012; Foundas et al, 1995; Hanna–Pladdy et al, 2003). Apraxia occurs in a variety of neurological diseases including stroke, dementia, and movement disorders (Park, 2017; Zadikoff and Lang, 2005). With a prevalence rate varying between 17 and 64%, a substantial number of patients with Parkinson's disease (PD) suffer from apraxic symptoms (Grossman et al, 1991; Leiguarda et al, 1997; Vanbellingen et al, 2012).…”

Apraxia is a deficit in central motor planning impairing praxis functions such as gesture production or tool use that affects a substantial number of patients with advanced Parkinson's disease. We investigated the functional connectivity of the praxis network in patients in early stages of Parkinson's disease having an increased risk for apraxia and evaluated the influence of dopaminergic therapy on praxis abilities and related networks. 13 patients with mild to moderate Parkinson's disease (ON and OFF dopaminergic therapy) and 13 healthy controls completed a praxis sensitive functional MRI task and apraxia assessments. Functional connectivity analyses included a graph theoretical approach analyzing the global efficiency within the praxis network followed by a seed-to-voxel functional connectivity analysis. Patients in the OFF but not in the ON state showed significantly lower praxis scores than controls. Patients in both states displayed higher global efficiency within the praxis network than controls revealing the bilateral supramarginal gyri as hubs. Seed-to-voxel functional connectivity analyses showed aberrations of right-hemispheric praxis areas in the OFF but not in the ON state. Patients in the ON state exhibited a significantly higher functional connectivity between the supramarginal gyrus and the primary motor cortex, basal ganglia, and frontal areas than in the OFF state. Dopaminergic therapy seems to normalize praxis abilities and related praxis networks in early stages of Parkinson's disease potentially by facilitating the propagation of long-term representations of object-related actions to motor execution areas.
