ABSTRACT
Brain-computer interface (BCI) technology enable humans to interact with external devices by decoding their brain signals. Despite it has made some significant breakthroughs in recent years, there are still many obstacles in its applications and extensions. The current used BCI control signals are generally derived from the brain areas involved in primary sensory- or motor-related processing. However, these signals only reflect a limited range of limb movement intention. Therefore, additional sources of brain signals for controlling BCI systems need to be explored. Brain signals derived from the cognitive brain areas are more intuitive and effective. These signals can be used for expand the brain signal sources as a new approach. This paper reviewed the research status of cognitive BCI based on the single brain area and multiple hybrid brain areas, and summarized its applications in the rehabilitation medicine. It's believed that cognitive BCI technologies would become a possible breakthrough for future BCI rehabilitation applications.
ABSTRACT
ObjectiveTo observe the status of social supports of the patients with advanced cancer and probe the effective nursing measures to improve the social supports of the patients.Methods"Social support rating scale"of Xiao Shui-yuan was applied to investigate the social support state of a total of 58 advanced cancer patients and 63 patients with chronic diseases.ResultsThe total score of patients with advanced cancer was(32.86±6.86),of patients with chronic diseases was(41.83±7.88).Compared with chronic disease group,the patients with advanced cancer received less social supports(P<0.05).The marriage state and economic income were significant factors to influence social support.ConclusionsThe patients with advanced cancer received less social supports than patients with chronic disease.Nursing staff should evaluate the status of social supports correctly,provide health education on patients and members in the net of social supports,make use of relative resources,then improve the social support level of the patients.
