“…In contrast, very few simulators assess skills used in microsurgery [20]- [22]. More importantly, effective assessment parameters to measure basic microsurgical skill have not been clearly identified, and are still under study [23]- [25]. Hand motion analysis, such as Imperial College Surgical Assessment Device (ICSAD), is a device proposed for use in objective assessment of microsurgical skill [26]- [28].…”

<span>This study aims to identify measurable parameters that could be used as objective assessment parameters to evaluate surgical dexterity using computer-based assessment module. A virtual reality module was developed to measure dynamic and static hand movements in a bimanual experimental setting. The experiment was conducted with sixteen subjects divided into two groups: surgeons (N = 5) and non-surgeons (N = 11). Results showed that surgeons outperformed the non-surgeons in motion path accuracy, motion path precision, economy of movement, motion smoothness, end-point accuracy and end-point precision. The six objective parameters can complement existing assessment methods to better quantify a trainee’s performance. These parameters also could provide information of hand movements that cannot be measured with the human eye. An assessment strategy using appropriate parameters could help trainees learn on computer-based systems, identify their mistakes and improve their skill towards the competency, without relying too much on bench models and cadavers.</span>

“…Among eye disorders, cataract is the most common cause of blindness worldwide. (1) Cataract prevalence is 50% in the age group of 65–75 years, reaching to 70% in those older than 75 years old. Currently, surgical intervention is the only treatment for cataract, with one million cataract surgeries annually performed in the United States.…”

Background: The patients under cataract sur-gery often experience anxiety not only during the surgery, but also prior to the surgery.Purpose: We sought to determine the effects of slow-stroke back massage on anxiety in patients undergoing cataract surgery. Setting: The study was conducted in the Amiral-momenin Hospital of Zabol city, south-east of Iran.Participants: A total of 60 candidates of cataract surgery participated in the study.Research Design: The participants were ran-domly allocated to either control or intervention groups. The intervention group received slow-stroke back massages, while patients in control group received routine interventions.Intervention: The slow-stroke back massage was performed on the patients assigned to the interven-tion group. The intervention was performed in the morning of the surgery day at 30 minutes before the surgery. The researcher performed each mas-sage session in a sitting position. The duration of each massage session was 15 minutes. Main Outcome Measures: Anxiety was assessed in the both groups in the morning of the surgery, before and immediately after the intervention. In-dependent samples Student’s t test, paired samples Student’s t test, and chi-squared test were used to analyze the data.Results: Anxiety was not significantly different between the two groups before and after the mas-sage (p = .816). On the other hand, paired samples Student’s t test showed a significant difference comparing the anxiety scores before (49.7±5.43) and after (45.16±3.89) the massage in the interven-tion group (p < .001). Conclusions: Based on our results, slow-stroke back massage, which is a low-cost and safe method, reduced anxiety in patients who were candidates for cataract surgery.

Este artículo describe el diseño y construcción de un entorno de realidad virtual inmersiva con una secuencia de escenas interactivas que recrean la composición de movimientos de una partícula para instruir el principio de superposición de movimientos en estudiantes de Física en ingeniería. El entorno virtual se ha desarrollado en Unity y permite la interacción por medio de las manos con visualización a través de un Head Mounted Display. Este artículo muestra la etapa de diseño, la programación y las principales características del entorno inmersivo logrado. Para probar el entorno inmersivo final se ha interactuado con una población de 20 estudiantes usando un test de 9 preguntas antes y después del uso del entorno inmersivo en cada estudiante. La ganancia normalizada que produce su uso en el grupo de estudiantes, sin acompañamiento y sin interacción social, es 〈g〉=0.08.
