There is limited evidence regarding the use of virtual reality (VR) and interactive video gaming for improving arm function because there are few such commercial devices and little relevant research. However, evidence of the greater effectiveness of upper extremity VR training over that of conventional therapy after stroke has recently grown due to the adoption of various therapeutic devices. VR applications are novel and potent technologies for upper extremity rehabilitation after stroke because the interface technologies, augmented reality technologies, and various sensorimotor feedback techniques are rapidly advancing. Going forward, VR technology should be designed to provide the possibility of intense functional repetitive practice for patients. The combination of VR with robotic devices, neuromodulation, mirror therapy, and telerehabilitation may synergistically improve upper extremity function after stroke. In severely injured patients, robotic interfaces should be considered, the level of difficulty should be fitted appropriately to the severity of the deficits, and the fact that it is difficult to train patients repeatedly and effectively in a real-world environment should be considered. Further research should be conducted on the application of VR programs in larger populations, VR involving various training paradigms, VR at different exercise levels, and the long-term sustained effects of VR. In addition, synergistically enhanced effects of combining other treatments and feedback paradigms with well-designed interfaces should be investigated.

2.Novel Virtual Reality Application in Field of Neurorehabilitation.
Brain & Neurorehabilitation 2018;11(1):e5-
Virtual reality (VR) therapy has many benefits to promote neurological and functional recovery in the field of neurorehabilitation after brain injury. VR-assisted neurorehabilitation can be applied in motor, sensori-motor, cognitive, activities of daily living (ADL), and telerehabilitation. Recent reports found that VR therapy appears to be a safe intervention that is effective at improving arm function and ADL function following stroke. Greater improvements were seen at a higher VR therapeutic dose. There has been insufficient evidence that VR therapy improved lower extremity gait speed, balance, and cognitive function after brain injury. As a result, the number of commercially available devices have increased and large-scale controlled trials have reported positive effects recently. Interface devices, various feedback methods, and the advancement of augmented reality technology are quickly developing, therefore, the potential value of VR therapy in neurorehabilitation will be high and its clinical application will be diversified.

OBJECTIVE: To delineate the changes in corticospinal excitability when individuals are asked to exercise their hand using observation, motor imagery, voluntary exercise, and exercise with a mirror. METHOD: The participants consisted of 30 healthy subjects and 30 stroke patients. In healthy subjects, the amplitudes and latencies of motor evoked potential (MEP) were obtained using seven conditions: (A) rest; (B) imagery; (C) observation and imagery of the hand activity of other individuals; (D) observation and imagery of own ipsilateral hand activity; (E) observation and imagery of the hand activity of another individual with a mirror; (F) observation and imagery of own symmetric ipsilateral hand activity (thumb abduction) with a mirror; and (G) observation and imagery of own asymmetric ipsilateral hand activity (little finger abduction) with a mirror. In stroke patients, MEPs were obtained in the A, C, D, E, F conditions. RESULTS: In both groups, increment of the percentage MEP amplitude (at rest) and latency decrement of MEPs were significantly higher during the observation of the activity of the hand of another individual with a mirror and during symmetric ipsilateral hand activity on their own hand with a mirror than they were without a mirror. In healthy subjects, the increment of percentage MEP amplitude and latency decrement were significantly higher during the observation of the symmetric ipsilateral hand activity with a mirror compared to the observation of the activity of the asymmetric ipsilateral hand with a mirror of their own hand. CONCLUSION: In both groups, corticospinal excitability was facilitated by viewing the mirror image of the activity of the ipsilateral hand. These findings provide neurophysiological evidence supporting the application of various mirror imagery programs during stroke rehabilitation.

Myopathy due to hypothyroidism can be detected in its early stage, but as the symptom is mild, complications such as rhabdomyolysis are rare. Thrombotic thrombocytopenic purpura in hypothyroidism is not yet clearly defined, and rare cases of it are reported. Reported herein is a case of thrombotic thrombocytopenic purpura and rhabdomyolysis associated with acute renal failure in hypothyroidism. A 70-year-old male was admitted to the hospital due to general weakness and muscle pain. Later, based on the laboratory findings, he was diagnosed with rhabdomyolysis associated with acute renal failure and thrombotic thrombocytopenic purpura combined with hypothyroidism. Initially, he was treated with fluid resuscitation due to rhabdomyolysis combined with acute renal failure but eventually, the levothyroxine supplement lowered the thyrotropin-stimulating hormone level. As a result, the patient recovered from rhabdomyolysis and thrombotic thrombocytopenic purpura without receiving plasmapheresis treatment.

Diabetic ketoacidosis (DKA), a fatal acute diabetic complication, is characterized by severe metabolic decompensation and intravascular volume depletion. These conditions may result in hypercoagulability and prothrombic state. Pulmonary thromboembolism (PTE) could be presented as an uncommon and life-threatening complication of DKA. Reported herein is a case involving a 54-year-old male patient who was admitted with DKA due to chronic alcohol consumption and stopping the intake of oral antidiabetic drugs. After low-molecular-weight heparin and warfarin treatment because of PTE during the DKA treatment, the patient's condition improved over the week that he was discharged on insulin and warfarin.

OBJECTIVES: Virtual reality has been increasingly used in the psychiatric field. Presence, the sense of "being there," is an essential concept in terms of the effectiveness of the virtual reality. The present study aimed to investigate the characteristics of the presence-related brain regions in patients with schizophrenia. METHODS: Using fMRI, brain activities were measured while performing the virtual reality tasks in fifteen healthy normal subjects and fifteen patients with schizophrenia. The tasks consisted of listening to some stories and inferring the content of the previous events. Ambiguous information was given for the experimental task, whereas clear information was given for the control task. Correlations between the image contrast values and the presence scores were analyzed. RESULTS: The presence-related brain regions in healthy controls were identified in the two discrete region groups that could be referred to as the cognitive neural correlates and the perceptual neural correlates. The former included the anterior cingulate, the left inferior temporal gyrus, the right lingual gyrus, and the right cuneus, whereas the latter consisted of the right posterior cingulate, the left lingual gyrus and the right fusiform gyrus. Compared with healthy controls, regional correlation patterns were different in patients with schizophrenia, including that the posterior cingulate had significant correlations. CONCLUSION: These results suggest that patients with schizophrenia utilize perceptual apparatus for the presence more than the cognitive aspect. A peculiar pattern of the presence in schizophrenia may be related to increased correlations between the posterior cingulate and other brain regions.

A 27-year-old male with nonobstructive hydronephrosis was referred from the urology department for polyuria evaluation and management. The patient was hospitalized for urinary tract infection and cystostomy was performed due to neurogenic bladder of unknown origin. The patient was of short stature and had visual impairment. From the interview, we discovered he had been suffering from polyuria and polydipsia for more than 20 years. Urine output was 13 L/day and urine osmolarity was 85 mOsm/kg. The results of a water deprivation test were consistent with central diabetes insipidus. Septo-optic dysplasia (SOD) was observed on brain magnetic resonance imaging (MRI). SOD is a very rare condition characterized by agenesis of the septum pellucidum or corpus callosum, which may cause optic nerve aplasia or hypoplasia, midbrain abnormalities and/or hypopituitarism. After desmopressin treatment, polyuria and hydronephrosis were improved. We report a case of a 27-year-old male diagnosed with SOD including diabetes insipidus, resulting in nonobstructive hydronephrosis.
