[Purpose] This study investigated the effects of purposeful action observation on upper extremity kinematic patterns in individuals with hemiplegia. [Subjects and Methods] Twelve patients were recruited in accordance with the inclusion criteria. The experimental group (n=6) was trained with a purposeful action observation program. The control group (n=6) was trained with only purposeful action without action observation. The programs were performed 30 min/session, 5 times per week for 30 sessions in 6 weeks of training. Upper extremity kinematic patterns were measured by a 3-dimensional motion analysis system before and after training, and the results were analyzed. [Results] The experimental group and the control group showed improvements in average velocity, trajectory ratio, and movement degree, but no statistically significant differences were observed between the groups. The experimental group showed statistically significant improvements in average velocity, trajectory ratio after the intervention. The experimental group also showed an improvement in movement degree, but the post-intervention difference was not significant. [Conclusion] The results of this study show that purposeful action observation training program improved the average velocity and trajectory ratio of stroke patients. Further research should enroll more subjects divided into more specific groups for treatment.

Background: Volunteers providing nursing services are among the first individuals to arrive at the scene after an incident; therefore, they must use their skills and capabilities to provide necessary care for the injured to prevent problems from worsening and complications from arising. Consequently, having structured empowerment courses for volunteers before disasters seems essential. This research aimed to determine the dimensions and components of empowering volunteer nursing service providers in disasters.

Purposeful movement often requires selection of a particular action from a range of alternatives, but how does the brain represent potential actions so that they can be compared for selection, and how are motor commands generated if movement is initiated before the final goal is identified? According to one hypothesis, the brain averages partially prepared motor plans to generate movement when there is goal uncertainty. This is consistent with the idea that motor decision-making unfolds through competition between internal representations of alternative actions. An alternative hypothesis holds that only one movement, which is optimized for task performance, is prepared for execution at any time.

Background: Sepsis is defined as invasion of pathogens into the blood stream together with the host response to this invasion. Thus, sepsis consists of the systemic inflammatory response syndrome (SIRS)caused by infection. It is a life-threatening condition that requires prompt detection and early definitive medical intervention.

Background: African Americans experience cardiovascular disease (CVD) disparities, and the burden is greatest in the rural south. Although evidence-based CVD prevention and management programs have been tailored to this context, implementation has been limited and not sustained long-term. To understand how to implement and sustain evidence-based CVD programs at scale, we must explore the perspectives of organizations serving rural African American communities and situate findings within foundational Implementation Science frameworks.
