Introduction: This study aimed to compare the dual-task and cognitive skills of problematic video gamers and non-problematic video gamers based on the fact that cognitive skills (e.g., inhibition, decision-making, attentional control, time perception) and dual-task performance may be positively affected in individuals who play games. Methods: The study was conducted on 62 individuals. The study group (n=33) consisted of individuals who played games, and the control group (n=28) consisted of non-gamers. Their scores on exercise benefits and barriers perception, cognitive performance, cognitive skills, and dual-task performances were measured. The Montreal Cognitive Assessment (MoCA) scale was used to evaluate cognitive function, and the Trail Making Test (TMT) was used to determine attention, speed, and better motor performance. The Stroop test was used to evaluate executive functioning. Results: It was determined that the problematic game players group was faster at the Stroop 1 and Stroop 2 test times (respectively p=0.020, p=0.005). In the comparison of dual task-cognitive 10-meter walking) test times of both groups, it was seen that individuals in the problematic game players group were faster than the control subjects (p=0.044). Conclusion: It can be said that playing digital games improves the cognitive dual-task cost (DTC) and the executive functioning of individuals.

Background: This study aims to examine the relationship between the post-earthquake anxiety status of victims of the Kahramanmaraş-centered earthquake and sleep problems, low back and neck pain. Materials and Methods: Individuals with a mean age of 27.9±9.1 years who experienced the Kahramanmaraş-centered earthquake were included in the study. The individuals included in the study was evaluated with the Beck Anxiety Inventory (BAI), the Oswestry Disability Index (ODI), the Neck Disability Index (NDI), and the Pittsburgh Sleep Quality Index (PSQI). Results: Of the participants, 67% were determined to have mild, moderate, and severe anxiety, and all of them had poor sleep quality (6.9±3.8). While the mean PSQI score of 57% of the participants sheltered in their own homes was 5 and above, this rate was 75% for those sheltered outside their homes. Of the individuals sheltered in their own homes, 27% and 37% of those sheltered outside their own homes had the ODI score percentages above 20%. A statistically moderate correlation was determined between the BAI score and the ODI score, the NDI score, and the PSQI score (r=0.511, r=0.604, r=0.539, respectively). Conclusions: Post-earthquake anxiety was revealed to be associated with sleep problems and low back and neck pain. Considering the relationship between the presence of anxiety, sleep problems, low back and neck pain in the support approaches to be adopted toward earthquake victims, approaches involving these parameters should be planned.

Objective: Muscle viscoelastic properties remain incompletely investigated in patients with chronic obstructive pulmonary disease (COPD). This study aimed to compare the viscoelastic properties of the accessory respiratory muscles and peripheral muscles between COPD patients and healthy individuals. Method: Sixty males were included in the study: patients with stable COPD and healthy adults (n=30 each). Pulmonary function was assessed using spirometry. Muscle viscoelastic properties, including tone (Hz), stiffness (N/m) and elasticity (E, inverse of logarithmic decrement), were quantified using MyotonPRO®. Result: Compared to the healthy group, the tone values of sternocleidomastoid muscles (SCM), left deltoid muscle (D), and left biceps brachii (BB) muscles were higher in the COPD group (bilateral SCMs; p < 0.001, left D; p = 0.014, left BB; p = 0.006). The stiffness values of SCMs (p < 0.001), as well as the left D (p = 0.008), and left BB muscles (p = 0.044) were also higher in the COPD group. The logarithmic decrements for the SCM, upper trapezius (UT), pectoralis major (PM), and D muscles bilaterally were higher in the COPD group (p = 0.031/p = 0.009; p < 0.01/p < 0.01; p = 0.006/p = 0.018; p = 0.005/p = 0.014, respectively, right/left side). Conclusion: Reduced elasticity of the respiratory muscles, particularly the SCM muscle, along with increased tone and stiffness, reflects a change in muscle viscoelastic properties in patients with COPD. Further studies are needed to assess the impact of COPD on the viscoelastic properties of lower extremity muscles.
