Assessment of Stress, Depressive and Anxiety Symptoms in Patients with COPD during In-Hospital Pulmonary Rehabilitation: An Observational Cohort Study.

Background and Objectives: The relationship between physical health and mental health has been considered for years. A number of studies have shown a correlation between depressive states and the progress of somatic diseases. It seems that the proper cooperation of specialists may result in the improvement of the patient's well-being and a positive effect on the course of the rehabilitation process. The aim of this study was to assess the symptoms of depression, anxiety, and stress in patients with chronic obstructive pulmonary disease (COPD) as well as the assessment of the relationship of psychological symptoms with sociodemographic factors and physical condition. Materials and Methods: The study enrolled 51 COPD patients who underwent a three-week pulmonary rehabilitation program. After admission to the rehabilitation department, the subjects were asked to complete the Hospital Anxiety and Depression Scale (HADS) questionnaire, the Perception of Stress Questionnaire (PSQ), and a sociodemographic questionnaire. Results: Anxiety states were diagnosed in 70% of respondents and depressive states were diagnosed in 54% of patients. Some of the respondents (14%) also showed a tendency to experience various grounded stresses. Additionally, there were correlations between the mental state and the results of fitness and respiratory tests. Conclusions: Patients with COPD are at risk for mental disorders, which may adversely affect their general health and significantly limit their physical and respiratory efficiencies. The development of widely available therapeutic solutions to reduce symptoms associated with depression, anxiety, and stress seems to be an important challenge for the management of patients with COPD.

Training Using a Commercial Immersive Virtual Reality System on Hand-Eye Coordination and Reaction Time in Young Musicians: A Pilot Study.

The implementation of virtual reality (VR) opens up a wide range of possibilities for the development of dexterity, speed and precision of movements. The aim of this study was to investigate whether immersive VR training affected the hand-eye coordination and reaction time in students of the state music school. This study implemented a single-group pre-post study design. This study enrolled 14 individuals, submitted to a 15 min training session of the immersive music game "Beat Saber", once a day for 5 consecutive days. The plate-tapping test (PTT) and the ruler-drop test (Ditrich's test) were used to assess the reaction time. Trial-making test (TMT) A and TMT B were used to assess coordination and visual attention. Analysis of the results showed a statistically significant improvement in hand-eye coordination and reaction time of music school students using the TMT-A (p < 0.002), TMT-B (p < 0.001), Ditrich's test for the non-dominant hand (0.025) and PTT (0.0001) after applying a week-long training period in immersive VR. The results obtained in the present study show that the VR system, along with the immersive music game, has the potential to improve hand-eye coordination and reaction time in young musicians, which may lead to the faster mastering of a musical instrument.
