Background/Objectives: Accurate plantar pressure assessment is essential for injury prevention and rehabilitation monitoring in sports. Wearable sensor technologies, such as DAid^® Smart Socks, offer portable, real-time biomechanical feedback and enable data collection in field conditions. However, there is limited evidence on their level of agreement with a gold standard in measuring the foot plantar center of pressure (CoP) in football-specific tasks. This study aimed to determine the preliminary validity of DAid^® Smart Socks compared with a gold-standard force platform in measuring plantar center of pressure (CoP) during functional football FIFA 11+ Part 2 exercises. Methods: Ten male volunteer youth football players (mean age 12.2 ± 0.42 years; height 158.7 ± 7.72 cm; weight 46.46 ± 8.78 kg; shoe size EU 39.8 ± 2.68) from the Latvian Football Federation Youth League participated. Eight players had right-leg dominance, two had left-leg dominance; three reported past lower-limb injuries. Plantar pressure was measured simultaneously using DAid^® Smart Socks and a 1.5 m entry-level force platform with a calibration factor of 3.2. Center of pressure (CoP) data from the force platform were recorded using Footscan software version 9.10.4. Participants performed two selected FIFA 11+ Part 2 exercises—a single-leg squat (unilateral) and a squat with heel raise, performed bilaterally—under standardized conditions. Each exercise was performed twice, with sock removal and reapplication between trials. Agreement between the DAid^® Smart Socks and the force platform was examined using waveform synchronization, root mean square error (RMSE), Bland–Altman analysis, and Lin’s Concordance Correlation Coefficient (CCC) to quantify both relative waveform correspondence and absolute CoP measurement accuracy. Results: Across 160 paired recordings, the DAid^® Smart Socks showed moderate-to-high correlation with the force platform for relative CoP dynamics, with 79% of waveforms demonstrating CCC ≥ 0.60. Absolute agreement was limited, with only 16% of recordings reaching CCC ≥ 0.90, and RMSE values ranging from 2.1 to 18.9 mm (X) and 4.3–34.2 mm (Y). Conclusions: DAid^® Smart Socks showed moderate-to-high correspondence with the force platform in capturing the directional and temporal characteristics of plantar CoP during functional football tasks, with agreement varying across individuals.

Background/Objectives: This study explores the perceived usefulness and use of artificial intelligence (AI)-based technologies as informational and emotional support among university students with and without disabilities. Methods: The sample consisted of 358 students from the University of Alicante, aged between 16 and 30 years; 88 participants identified as having a disability, while 270 reported no disability. The gender distribution was balanced, with 53% women and 47% men. An ad hoc questionnaire was applied to evaluate familiarity, frequency of use, and perceived usefulness of AI as a means of obtaining informational and emotional support. Results: The results of the multivariate analyses indicated that students without disabilities reported greater familiarity with and more frequent use of AI tools compared to students with disabilities. Significant differences were found in perceived usefulness for obtaining both informational and emotional support, with higher ratings among students without disabilities, and a moderate effect size. Moreover, frequency of use was positively associated with perceived usefulness in both groups, suggesting that practical experience influences users’ evaluations. Discussions: The findings suggest that students perceive AI as a useful resource for informational and emotional support. However, as with other technologies, addressing accessibility and perception gaps is crucial to promote effective inclusion in university settings.

Background/Objectives: Return to work (RTW) after an industrial accident is crucial for an individual’s well-being and socioeconomic recovery. This study investigated factors influencing RTW among workers who sustained physical or brain lesion-related disabilities following industrial accidents. Methods: Using five-year panel data (2018–2022) from the Panel Study of Workers’ Compensation Insurance of South Korea, we analyzed 340 individuals with physical or brain lesion-related disabilities sustained from industrial accidents. We used logistic regression models to identify factors associated with RTW and return to employed (RTE) status. Results: The RTW and non-RTW groups comprised 160 and 180 participants, respectively. Factors associated with non-RTW included female sex (adjusted odds ratio [aOR], 0.33; 95% confidence interval [CI], 0.13–0.86; p = 0.023), injury caused by disease (aOR, 0.18; 95% CI, 0.05–0.66; p = 0.010), long recovery periods (aOR, 0.27; 95% CI, 0.10–0.72; p = 0.009), low self-confidence (aOR, 0.16; 95% CI, 0.07–0.35; p < 0.001), and older age (aOR, 0.08; 95% CI, 0.02–0.34; p = 0.001). Workers with no blood pressure problems (aOR, 2.21; 95% CI, 1.11–4.38; p = 0.024) and longer employment durations (aOR, 3.84; 95% CI, 1.15–12.81; p = 0.029) had a higher chance of RTW. Similar factors were associated with RTE, with more emphasis on older age, long recovery periods, low self-confidence, and injury caused by disease. Conclusions: Our findings contribute to developing targeted support services and informing policy decisions to improve RTW for workers with physical or brain lesion-related disabilities caused by industrial accidents.
