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.

As Korea is one of the fastest aging countries in the world, the management of dementia has become a major social issue. An ideal way of treating dementia is to prevent the onset of the disease, as effective cure remains elusive yet. Therefore, every effort is needed to provide any interventions to delay the progression of dementia. Comprehensive assessment of dementia includes evaluation of cognitive functions, activities of daily living and neurobehavioral symptoms. Detailed history from the family member or the caregiver is essential and standardized assessment tools are recommended when evaluating a patient's functions. By putting all the information together, we estimate the severity of the disease and the prognosis to set up a therapeutic plan. As the incidence of dementia is on the rise, it is advisable for all members of rehabilitation medicine team to be well-acquainted with the assessment methods of dementia for early identification of problems and the monitoring of therapeutic interventions. This article provides a brief overview of the assessment of dementia to assist clinicians in evaluating and treating these patients.

OBJECTIVE: To investigate the effects of using motor imagery (MI) in combination with a virtual reality (VR) program on healthy volunteers and stroke patients. In addition, this study investigated whether task variability within the VR-guided MI programs would influence corticomotor excitability. METHODS: The present study included 15 stroke patients and 15 healthy right-handed volunteers who were presented with four different conditions in a random order: rest, MI alone, VR-guided MI, and VR-guided MI with task variability. The corticomotor excitability of each participant was assessed before, during, and after each condition by measuring changes in the various parameters of motor-evoked potentials (MEPs) of the extensor carpi radials (ECR). Changes in intracortical inhibition (ICI) and intracortical facilitation (ICF) were calculated after each condition as percentages of inhibition (%INH) and facilitation (%FAC) at rest. RESULTS: In both groups, the increases in MEP amplitudes were greater during the two VR-guided MI conditions than during MI alone. Additionally, the reductions in ECR %INH in both groups were greater under the condition involving VR-guided MI with task variability than under that involving VR-guided MI with regular interval. CONCLUSION: The corticomotor excitability elicited by MI using a VR avatar representation was greater than that elicited by MI with real body observations. Furthermore, the use of task variability in a VR program may enhance neural regeneration after stroke by reducing ICI. The present findings support the use of various VR programs as well as the concept of combining MI with VR programs for neurorehabilitation.

To develop the occupational cancer surveillance system in Korea, data linkage analysis was performed on the subjects of Health-monitoring-pocketbook (the list of subjects who were exposed to selected occupational carcinogens) and the retired workers of a cokes manufacturing factory using the Korean medical insurance data, Korean death certificate data and Korean cancer registry data. Study subjects comprised the 822 retired subjects and the 3101 present-post subjects of Health-monitoring-pocketbook and the 182 retired workers of a cokes manufacturing factory. The incidence of cancer of these study subjects was ascertained by linkage of Korean medical insurance data of year 1995-6, Korean death certificate data of year 1992-8 and Korean cancer registry data of year 1993-5. In the study subjects, Eighty seven percent were males and mean age was 39.3+/-8.9 year-old, Average work duration was 8.0+/-5.5 years. Chrome, asbestos and cokes were the most frequent exposed agents. In the study subjects, total 13 cancer cases were ascertained by data linkage analysis. In the ascertained cancer cases, 8 cases were male and 5 cases were female, and 7 cases were aged 40-49 yr, 5 cases were aged 50-59 yr and 1 cases were aged 30-39 yr. The commonest exposure agent in the ascertained cancer cases was asbestos and cokes. By the site of cancer, 3 stomach cancer cases, 2 hematopoietic cancer cases and 2 biliary tract cancer cases were ascertained. The occupational cancer surveillance system using data linkage analysis on the workers exposed to hazardous agents was the most feasible and efficient method in Korea. And to do this, establishment of occupational history information in several disease registry database is needed with the effort of estimating the proper size of workers exposed hazardous agents.

OBJECTIVE: We studied the use of smartphone technology in stroke rehabilitation in Korea and gathered opinions on how it would best be utilized it in a clinical setting. METHOD: Physiatrists, occupational therapists, physical therapists, and rehabilitation ward nurses were surveyed to examine smartphone propagation among the rehabilitation team, current therapeutic knowledge, the use of smartphone technology, and perceptions regarding the potential therapeutic use of smartphones in rehabilitation. The respondents were also asked to specify the applications considered to be the most appropriate for rehabilitation. We also examined applications available for stroke rehabilitation at Android and Apple stores. RESULTS: Of the respondents, 92% had never using smartphone technology in rehabilitation with their clients. The greatest barrier to use was that "smartphone technology and appropriate applications were not available for rehabilitation settings" (71.4%). Areas identified as most appropriate for smartphone use in therapy included provision of information (82.4%) and cognitive (72.5%) and language training (68.1%). We found only a few applications in android and Apple application stores. Of the respondents, 89% intended to use smartphone applications in rehabilitation in the future. CONCLUSION: Smartphone applications developed for stroke rehabilitation are promising. Further research and the development of new therapeutic applications for use in rehabilitation and across health care are needed.
