Motor Imagery for Gait Rehabilitation in Post-Stroke Hemiparesis

Abstract: Background and Purpose . Reports have described the contribution of motor imagery (MI) practice for improving upper-extremity functions in patients with hemiparesis following stroke. The purpose of this case report is to describe the use of MI practice to attempt to improve walking in an individual with hemiparesis. Case Description. A 69-year-old man with left hemiparesis received MI gait practice for 6 weeks. Intervention focused on task-oriented gait and on impairments of the affected lower limb. Preintervention, midterm, postintervention, and follow-up measurements of temporal-distance stride parameters and sagittal kinematics of the knee joint were taken. Main Outcomes . At 6 weeks postintervention, the patient had a 23% increase in gait speed and a 13% reduction in double-support time. An increase in range of motion of the knees also was observed. No changes in gait symmetry were noted. Discussion . The outcomes suggest that MI may be useful for the enhancement of walking ability in patients following stroke. Because improvement was mainly in temporal-distance gait variables and knee movement, imagery practice probably should focus on its specific impairments during gait in order to affect the performance of the paretic lower extremity.

Surviving the Holocaust: A Meta-Analysis of the Long-Term Sequelae of a Genocide

Abstract: The current set of meta-analyses elucidates the long-term psychiatric, psychosocial, and physical consequences of the Holocaust for survivors. In 71 samples with 12,746 participants Holocaust survivors were compared with their counterparts (with no Holocaust background) on physical health, psychological well-being, posttraumatic stress symptoms, psychopathological symptomatology, cognitive functioning, and stress-related physiology. Holocaust survivors were less well adjusted, as apparent from studies on nonselected samples (trimmed combined effect size d = 0.22, 95% CI [0.13, 0.31], N = 9,803) and from studies on selected samples (d = 0.45, 95% CI [0.32, 0.59], N = 2,943). In particular, they showed substantially more posttraumatic stress symptoms (nonselect studies: d = 0.72, 95% CI [0.46, 0.98], N = 1,763). They did not lag, however, much behind their comparisons in several other domains of functioning (i.e., physical health, stress-related physical measures, and cognitive functioning) and showed remarkable resilience. The coexistence of stress-related symptoms and good adaptation in some other areas of functioning may be explained by the unique characteristics of the symptoms of Holocaust survivors, who combine resilience with the use of defensive mechanisms. In most domains of functioning no differences were found between Israeli samples and samples from other countries. The exception was psychological well-being: For this domain it was found that living in Israel rather than elsewhere can serve as a protective factor. A biopsychological stress-diathesis model is used to interpret the findings, and future directions for research and social policy are discussed.

A visitor's guide in an active museum: Presentations, communications, and reflection

Abstract: Technology can play a crucial role in supporting museum visitors and enhancing their overall museum visit experiences. Visitors coming to a museum do not want to be overloaded with information, but to receive the relevant information, learn, and have an overall interesting experience. To serve this goal, a user-friendly and flexible system is needed. The design of such a system poses several challenges that need to be addressed in parallel. The user interface should be intuitive and let the visitors focus on the exhibits, not on the technology. Content and delivery must provide relevant information and at the same time allow visitors to get the level of detail and the perspectives in which they are interested. Personalization may play a key role in providing relevant information to individuals. Yet, since visitors tend to visit the museum in small groups, technology should also contribute to and facilitate during-the-visit communication or post-visit group interaction. The PIL project applied at the Hecht museum extended the research results of the PEACH project and tried to address all of these considerations. Evaluation involving users substantiated several aspects of the design.
