Visual stimulation as pain relief for Hong Kong Chinese patients with leg ulcers

Analgesic potential of visual stimulation was examined in 33 patients with leg ulcers in a randomized, controlled, crossover clinical trial. Patients were alternating between wearing an eyeglass display with soundless VCD broadcast (V-sessions) and a static blank screen (B-sessions) while receiving superficial debridement and wound dressing for their leg ulcers. A significant reduction in pain scores was found during V-sessions (VAS 67.7 ± 28.4 vs. 25.6 ± 29.8 when V-sessions vs. B-sessions, with p < 0.01). Age was positively correlated with the improvement in VAS, whereas gender, residency, and the underlying medical conditions were not correlated with the improvement in pain score. The use of visual stimulation might be beneficial to both genders, in an older age group regardless of the underlying medical conditions. This is the pioneer use of visual stimulation as a non-pharmacological adjuvant to pain relief among a local Chinese population. The study will certainly add knowledge to the existing pain relief methods.published_or_final_versio

The effect of visual stimulation via the eyeglass display and the perception of pain

Hospitalization involves anxiety and pain for many people. Unfamiliar hospital settings, various diagnostic and therapeutic procedures, and the sight and sounds of medical procedures exacerbate pain and anxiety. By blocking off the anxiety-inducing sights and sounds of the hospital surroundings and creating a pleasant environment, an eyeglass display might be able to change the sensation and perception of pain. In this randomized, controlled, crossover study, 72 healthy university student volunteers were asked to wear a light-weight eyeglass that projected a feeling of watching a 52-inch television screen at 6 1/2 feet in distance while pain was produced by a modified tourniquet technique. Subjects were randomly assigned to participate in a V-session or B-session first, with subsequent cross-over. In a V-session, subjects were instructed to wear the eyeglass and watch the soundless display of natural scenery during the inflation. In a B-session, the eyeglass that subjects wore would project a static blank screen. During V-sessions, there was a significant increase in pain threshold (p < 0.001) and pain tolerance (p < 0.001). The degree of immersion was positively correlated with improvement in pain threshold, whereas the anxiety level was negatively correlated with improvement in pain threshold. These findings have implications for using visual stimulation as a positive adjunct to other methods of pain relief and for different pain conditions. This study was considered to be the pioneer use of visual stimulation in the local Chinese community as an adjunct to pain relief.published_or_final_versio

Virtual learning object for the simulated evaluation of acute pain in nursing students

This study aimed to evaluate the results of the application of a virtual learning object for the simulated evaluation of acute pain in the learning of undergraduate nursing students and to verify the opinions of the students regarding the quality of the technology. This was a quasi-experimental, non-randomized, before and after study performed with 14 students in the seventh phase of the undergraduate nursing course of the Federal University of Santa Catarina. The pre (8.84) and post-test (9.31) means revealed significant differences in learning after the intervention (p=0.03). In the qualitative evaluation the flexibility of access, access independent of time/place, freedom to decide the best learning route and the similarity with reality were highlighted. It constitutes a promising educational tool, an interactive experience, similar to reality, dynamic and constructive learning. The application of the technology has brought positive results for learning about pain evaluation, contributing to fill the gap in the teaching of the thematic.El objetivo del estudio fue evaluar los resultados de la aplicación de un objeto virtual de aprendizaje para evaluación simulada de dolor agudo en el aprendizaje de estudiantes de graduación en enfermería y verificar su opinión sobre la calidad de la tecnología. Se trata de un estudio casi experimental, no aleatorio, del tipo antes y después, realizado con 14 estudiantes de la séptima fase de la graduación en enfermería de la Universidad Federal de Santa Catarina. Los promedios de la prueba, antes (8,84) y después (9,31), revelaron diferencia significativa en el aprendizaje después de la intervención (p=0.03). En la evaluación cualitativa se destacaron la flexibilidad de acceso, el acceso independiente de tiempo/lugar, libertad para decidir el mejor curso de aprendizaje y la semejanza con la realidad. Constituye una promisora herramienta educacional, una experiencia interactiva, semejante a la realidad, dinámica y constructiva de aprendizaje. La aplicación de la tecnología presentó resultados positivos para el aprendizaje de la evaluación del dolor, contribuyendo para llenar un vacío en la enseñanza de la temática.O objetivo do estudo foi avaliar os resultados da aplicação de um objeto virtual de aprendizagem para avaliação simulada da dor aguda na aprendizagem de estudantes de graduação em enfermagem e verificar sua opinião sobre a qualidade da tecnologia.
