    The use of serious game tools in training of medical professions is steadily growing. However, there is a lack of reliable performance assessment methods to evaluate learner's outcome. The aim of this study is to determine whether functional near infrared spectroscopy (fNIRS) can be used as an additional tool for assessing the learning outcome of virtual reality (VR) based learning modules. The hypothesis is that together with an improvement in learning outcome there would be a decrease in the participants' cerebral oxygenation levels measured from the prefrontal cortex (PFC) region and an increase of participants' serious gaming results. To test this hypothesis, the subjects were recruited and divided into four groups with different combinations of prior virtual reality experience and prior Basic Life Support (BLS) knowledge levels. A VR based serious gaming module for teaching BLS and 16-Channel fNIRS system were used to collect data from the participants. Results of the participants' scores acquired from the serious gaming module were compared with fNIRS measures on the initial and final training sessions. Kruskal Wallis test was run to determine any significant statistical difference between the groups and Mann-Whitney U test was utilized to obtain pairwise comparisons. BLS training scores of the participants acquired from VR based serious game's the learning management system and fNIRS measurements revealed decrease in use of resources from the PFC, but increase in behavioral performance. Importantly, brain-based measures can provide an additional quantitative metric for trainee's expertise development and can assist the medical simulation instructors.

    OBJECTIVE Virtual reality programs, which have developed rapidly with the advancement of technology, have led to the development of alternative treatment methods preferred in rehabilitation. This study aimed to investigate the acute effects of a video game-based exercise program applied after breast cancer surgery on the upper extremity functionality, pain severity, and the level of fatigue. METHODS Fifteen female patients aged between 30 and 60 years (50.13 +/- 8.79) who completed their 12th week after breast cancer surgery and were received adjuvant chemotherapy treatment were randomly included in this pre-test and post-test study. The patients were performed a 30-min video game-based exercise program. The muscle strength, range of motion (ROM), pain and fatigue level assessments were performed before and after the video game-based exercises. The level of exercise pleasure was determined with the modified visual analog scale. RESULTS Shoulder flexion, abduction, and external rotation ROM significantly increased after video game-based exercise program. No difference was detected for shoulder abduction muscle strength (p>0.05) and pain level significantly increased (p<0.05). The average exercise pleasure level is 4.5/5 and the average fatigue level was 11.13/20. CONCLUSION Video game-based exercises provided improvement in ROM of the shoulder joint without causing fatigue. Studies with different treatment durations are needed to minimize the increase in pain level.
