OBJECTIVE: Reusi Dat Ton, also known as Thai Yoga, is a traditional therapeutic exercise recognized for its potential in managing health issues such as office syndrome and stress. This study aimed to evaluate the effects of Reusi Dat Ton on neck and shoulder range of motion (ROM) using inertial measurement unit (IMU) technology, and on stress levels assessed via heart rate variability and the Suanprung Stress Test-20 (SPST-20).METHODS: Forty-five participants (21 males, 24 females) with a mean age of 35.73 years and a mean body mass index of 23.49 were evaluated pre and post intervention in a 20-minute five specific Reusi Dat Ton therapeutic exercises. Stress levels were assessed using the SPST-20 and a cardiac health monitor, while ROM was measured using the Ultium Motion system with IMU technology.RESULTS: The Reusi Dat Ton intervention led to significant reductions in SPST-20 scores (p < 0.001) and heart rate (p < 0.001), along with significant improvements in stress resilience (p < 0.01) and right shoulder flexion (p < 0.05).CONCLUSION: Reusi Dat Ton effectively reduced stress levels, enhanced stress resilience, and improved right shoulder mobility. These findings support its use as a therapeutic exercise for individuals with office syndrome and related conditions.

Background: Individuals with lower-limb amputations are highly dependent upon prostheses to perform daily activities and adapt to environmental changes. Transtibial prosthesis (TTP) users in particular, experience greater challenges in motor control and demonstrate impaired cognitive functions, when compared to able-bodied persons. The identification of neural mechanisms underlying adaptation or compensation may contribute to the development and expansion of rehabilitation strategies. Objective: To examine neuroplasticity changes in transtibial amputees by analyzing event-related potentials (ERPs) obtained from Electroencephalogram (EEG) during Go/No-Go tasks to assess cognitive control and neural adaptations. Methods: Twenty-eight TTP users and twenty-eight able-bodied persons were recruited. EEG was recorded in eyes-open resting states, and ERPs during a Go/No-go task. Results: Our findings demonstrate that, during the resting-state, the TTP users group exhibited no significant differences in brain activity across regions. However, during Go/No-go task, an increase of N2 amplitude was observed, and significant reduction in the amplitude of P3 amplitude was noted when compared to able-bodied group. Conclusion: These findings demonstrated neural modifications by individuals with transtibial amputation, particularly in relation to inhibitory control, which is essential for effective attentional control. Deficits in inhibitory control may interfere with decision-making processes, thereby impairing the execution of daily activities that require sustained attention and cognitive flexibility. Based on these findings of neural adaptions, it may be necessary to consider targeted interventions aimed at enhancing cognitive control and incorporating specific cortical training strategies for TTP users.

The psychological states are essential to maintain a healthy balance and optimize performance, especially in athletes. Sex-related differences in elite athletes are one of the important factors, which are ambiguous. This study aims to explore sex differences in psychological states of 36 professional athletes (12M/24F, 21.6±3.9 y, 166.3±8.9 cm, 56.4±11.3 kg, mean±SD) in the lead-up to a major international competition using objective (quantitative electroencephalogram, QEEG) and subjective measures (Athletic Coping Skills Inventory, ASCI-28). Participants included fifteen gymnasts, eleven swimmers, and ten e-sports players. QEEG measurements were collected during 5 minutes at rest before athletes completed the ASCI-28 scale. Data were obtained during training camp within 3 months before the competition. QEEG data were analyzed using a generalized linear mixed modeling (GLMM) to report the linear predictor of QEEG in brain areas (random) and sex (fixed). A multivariate analysis of variance (MANOVA) was applied to ACSI-28 subscales data to compare sex groups. Female athletes exhibited higher EEG activity in the theta power in the parietal and occipital areas and the beta power in the pre-frontal and temporal areas. Furthermore, significant sex differences were found in the coping with adversity (p =0.038) and goal setting/mental preparation subscales of the ACSI-28. The correlations between the QEEG and questionnaire scores were low to moderate correlations for female athletes, and moderate correlations for male athletes. A significant correlation was observed in both male and female athletes between activity in the temporal region within theta and beta frequency bands (QEEG), and the coping with aversity subscale (questionnaire). These findings provide valuable insights for sports psychologists to design appropriate psychological interventions and for future studies examining the impact of differential psychological interventions for male and female athletes to optimize well-being and performance.

Single-leg drop landing (SLDL) and jump landing (SLJL) are frequently used as assessment tools for identifying potential high-risk movement patterns; thus, understanding differences in neuromuscular responses between these types of landings is essential. This study aimed to compare lower extremity neuromuscular responses between the SLDL and SLJL. Thirteen female participants performed an SLDL and SLJL from a 30-cm box height. Vertical ground reaction force (vGRF), time to peak vGRF, and surface electromyography (sEMG) data were collected. Continuous neuromuscular responses, peak vGRF, and time to peak vGRF were compared between the tasks. Statistical parametric mapping (SPM) analysis demonstrated that the SLJL had a significantly higher sEMG activity in the rectus femoris (RF), vastus lateralis (VL) and vastus medialis (VM) within the first 10% of the landing phase compared with SLDL. At 20–30% of the landing phase, sEMGs in the RF and VL during the SLDL were significantly higher compared with SLJL (p < 0.05). A higher peak vGRF and shorter time to peak vGRF was observed during SLJL (p < 0.05). In conclusion, our findings highlight that SLJL exhibited greater RF, VL, and VM activities than SLDL at initial impact (10% landing), coinciding with a higher peak vGRF and shorter time to attain peak vGRF. Our findings support the role of the quadriceps as the primary energy dissipator during the SLJL.
