Theological engagement with artificial intelligence has largely focused on applied ethics, addressing bias, governance, and labor displacement. While indispensable, this framing often presumes that algorithmic systems operate as external instruments acting upon already constituted subjects. This article argues that contemporary predictive architectures intervene at a deeper anthropological level by structuring attention, expectation, and habituation prior to deliberative judgment. It introduces the concept of ordo extractionis to designate a technologically mediated regime of formation characterized by behavioral trace extraction, probabilistic modeling, and recursive projection of statistically inferred continuity. Drawing on Augustine’s account of ordered love and temporality and Aquinas’s doctrine of habitus and the invisible mission of the Spirit, the article distinguishes algorithmic projection from sanctification as divergent pedagogies of temporal formation. Predictive systems stabilize continuity by extrapolating from measurable past behavior; sanctification reorders desire teleologically toward a final end not deducible from prior pattern and grounded in non-competitive divine causality. Algorithmic mediation is therefore interpreted pedagogically rather than metaphysically: it does not rival divine agency but participates creaturely in shaping the ecology within which habituation unfolds. Engagement with contemporary AI research on recommender systems, reinforcement learning, and generative models situates the argument within technological realism and resists determinism. The digital twin is analyzed as a probabilistic representation that acquires institutional authority when operationalized in ranking, profiling, and evaluative systems, without constituting a metaphysical competitor to the imago Dei. In response to anticipatory closure, Eucharistic anamnesis and epiclesis are developed as practices that re-situate memory and expectation within eschatological promise. The article concludes that the central theological question posed by AI is not whether machines can think, but how formative sovereignty over desire is exercised within technologically mediated modernity.

Background: Facial movement symmetry is an important indicator of neuromuscular function, with asymmetries associated with neurological disorders, trauma, and surgery. Quantitative symmetry assessment supports diagnosis, therapy monitoring, and surgical planning. This study proposes a marker-based approach to improve tracking stability and investigates whether dynamic facial movement descriptors can distinguish symmetric from asymmetric exercise execution. Methods: Videos were recorded using a low-cost acquisition setup during two facial exercises: eyebrow raising and smiling (75 patient; mean age 14 ± 4 years). Seventeen ArUco markers were placed at predefined facial landmarks. The dataset comprised 134 recordings labeled as symmetric (S) or asymmetric (AS). The processing pipeline included marker and face detection, symmetry axis estimation, feature extraction, and statistical analysis. Features were based on distances between paired markers and the estimated facial symmetry axis, yielding two dynamic descriptors: VertDist (vertical displacement) and Ratio (relative position across facial halves), along with their first derivatives. Results: Group differences between S and AS movements were analyzed using Welch’s t-test with effect sizes quantified by Hedges’ g. Statistically significant differences were found primarily in the first derivatives of VertDist and Ratio. For eyebrow raising, VertDist showed large effects (Hedges’ $\left|g\right|=1.41-1.42$) and Ratio moderate effects ($\left|g\right|=0.75-0.87$). For smiling, VertDist demonstrated moderate effects ($\left|g\right|=0.87-0.93$), while Ratio exhibited large effects ($\left|g\right|=1.14-1.21$). Conclusions: The proposed marker-based method enables reliable, low-cost quantitative assessment of facial movement asymmetry. Dynamic descriptors derived from VertDist and Ratio effectively differentiate symmetric and asymmetric facial movements. Full article

Introduction: Disc displacement with reduction (DDwR) and myalgia are among the most common temporomandibular disorders, frequently affecting young adults. While conservative therapy is considered the first-line approach, the evidence on long-term outcomes is still limited. Case Presentation: A 22-year-old female had a 7-month history of left-sided TMJ clicking, deviation to the left during opening, and 2 months of bilateral masticatory pain, which was worsened by mastication. During clinical examination, reproducible left TMJ clicking and tenderness of the masseter and temporal muscles were observed. Based on DC/TMD Axis 1, DDwR with myalgia diagnosis was made. Intervention and Results: A full maxillary stabilization splint was constructed and delivered together with patient education, dietary adjustments, and guided mandibular exercises. At baseline, pain intensity was VAS 6/10 with a maximum unassisted mouth opening of 41 mm and reproducible joint clicking. After 2 weeks, the patient reported a decrease in pain, VAS 2/10, mouth opening was 44 mm, and joint sounds were absent. After 1 year, the patient was asymptomatic (VAS 0/10) with stable function, preserved mouth opening, and completion of daily activities without limitations. Clinical Relevance and Conclusions: This case shows that multi-directional non-invasive therapy can result in complete and long-term remission of DDwR with myalgia. It emphasizes the need for careful diagnosis, through standardized instruments such as DC/TMD, and the need for personalized treatment to ensure durable clinical success. Full article

Background: Conservative treatment for adolescent idiopathic scoliosis (AIS) includes physiotherapeutic scoliosis-specific exercises (PSSE) and bracing. One PSSE-based approach is the Rigo Concept, which emphasizes three-dimensional (3D) postural correction, expansion techniques, muscle activation, and postural integration. Recently, increasing interest has been directed toward incorporating whole-body vibration (WBV) into physiotherapy. WBV is a reflex-based neuromuscular training method shown to improve muscle strength and power and enhance proprioception, which may be beneficial in the treatment of AIS. Objectives: This study aimed to assess the effects of physiotherapy based on the Rigo Concept combined with WBV on sagittal spinal curvatures, trunk symmetry, and the angle of trunk rotation (ATR) in girls with AIS. Methods: This prospective controlled experimental study included 45 girls (12.8 ± 1.7 years) with AIS who participated in a 5-day physiotherapy session based on the Rigo Concept. Of these, 22 participants additionally received WBV using a Galileo Med 35 platform (3 × 3 min/day, frequency 25 Hz, peak-to-peak displacement 2 mm), forming the Rigo–WBV group. The remaining participants received the Rigo Concept alone (Rigo–ONLY). Participants were allocated to the study groups using a quasi-random method based on the order of enrollment. ATR was defined as the primary endpoint, while thoracic kyphosis, lumbar lordosis, sacral slope, coronal balance, and scapular position were considered secondary outcomes. All outcomes were assessed before and after the intervention. Results: Neither the Rigo–WBV nor the Rigo–ONLY intervention affected sagittal spinal curvatures (p > 0.05). Coronal balance improved in both the Rigo–WBV (Δ 0.5 cm, p < 0.001) and Rigo–ONLY groups (Δ 0.4 cm, p = 0.005). In the Rigo–ONLY group, an improvement in scapular height asymmetry was observed (Δ 1.1°, p = 0.010). Following the Rigo–WBV intervention, ATR decreased in the main thoracic (Δ 1.9°, p < 0.001), thoracolumbar (Δ 1.9°, p < 0.001), lumbar curve (Δ 2.1°, p < 0.001), and pelvis (Δ 1.0°, p < 0.001). In the Rigo–ONLY group, a reduction in ATR was observed only in the thoracolumbar curve (Δ 1.9°, p < 0.001). Conclusions: In terms of clinical and postural changes, five-day physiotherapy based on the Rigo Concept, with or without WBV, does not influence sagittal spinal curvatures in girls with AIS. Both interventions may improve coronal balance. Moreover, the Rigo Concept combined with WBV may reduce ATR. Full article

Sedentary behavior contributes to obesity and metabolic dysfunction, yet few interventions individualize exercise intensity using fuel-based metrics such as the respiratory exchange ratio (RER; VCO₂/VO₂). This study investigated the effects of metabolically guided walking combined with whole-food, plant-based nutrition on body composition and metabolic outcomes in sedentary overweight and obese women. Forty-four women mean age 43 years; BMI 30.1 kg·m⁻²) were randomized to low-intensity continuous training (LICT; RER ≈ 0.75), moderate-intensity intermittent training (MIIT; RER ≈ 0.85), or high-intensity continuous training (HICT; RER ≈ 0.95). Following a 2-week dietary lead-in with an individualized ~200 kcal·day⁻¹ energy deficit, participants completed an 8-week RER-guided walking program (5 sessions·week⁻¹; 15–50 min·session⁻¹). Assessments included air-displacement plethysmography (BodPod) body composition, resting metabolic rate and substrate utilization, and oxygen uptake at the first ventilatory threshold (VT1). Data were analyzed using ANCOVA, mixed-factorial ANOVA, and Pearson correlations. Percent body fat decreased significantly across participants (p < 0.0001, η² = 0.827), with MIIT demonstrating the most favorable integrated outcomes. MIIT elicited the largest reductions in total body mass (−11.2%), fat mass (−25.9%), and percent body fat (−17.1%), alongside improvements in VT1 VO₂ (Δ = 1.487 ± 0.895 L·min⁻¹; p = 0.038). Resting respiratory quotient (RQ) declined in LICT and MIIT but increased in HICT, corresponding with increased fat oxidation in LICT and MIIT and reduced fat oxidation in HICT. Changes in RQ were significantly associated with changes in percent body fat (r = 0.316, p = 0.039). Metabolically guided moderate-intensity intermittent walking combined with whole-food, plant-based nutrition produced the most consistent improvements in adiposity, substrate utilization, and submaximal fitness, supporting the public-health feasibility of a community-deliverable, substrate-informed walking prescription.

Background: Neoprene knee sleeves are commonly used to enhance joint stability and mechanical performance during resistance training. However, the specific influence of sleeve density on the force–velocity–power (F–V–P) profile during multi-joint lower-body exercises such as the back squat remains unclear. This study aimed to compare the theoretical F–V–P parameters derived from back squat performance while wearing low-density (LD) versus high-density (HD) knee sleeves. Methods: Fifteen resistance-trained males completed an incremental back squat test under both LD and HD conditions. A linear position transducer recorded barbell displacement and velocity. Individual force–velocity relationships were modelled to determine maximal theoretical force (F₀), velocity (V₀), power (Pmax), and the F–V slope. Paired-sample t-tests, linear mixed models, and Cohen’s d effect sizes were calculated. Clinical relevance was assessed using a threshold defined as 0.2 × the standard deviation of the HD condition. Bayesian analyses were conducted to estimate the probability and magnitude of the observed effects. Results: No statistically significant differences were observed between sleeve conditions for F₀, V₀, Pmax, or F–V slope (p > 0.05, d ≤ 0.37). Nonetheless, HD sleeves yielded slightly higher mean values for F₀, V₀, and Pmax, exceeding the predefined threshold for practical relevance. Bayesian models showed moderate probabilities (~0.80) that HD sleeves outperformed LD, though with limited chances of crossing the clinical significance threshold. Conclusions: Although HD sleeves do not produce systematic changes in F–V–P parameters, their increased material stiffness may provide small yet practically meaningful mechanical advantages in high-force resistance training contexts.

Background: Obesity, defined as an abnormal accumulation of body fat, is becoming a global epidemic. Individuals with obesity may present with increased abdominal fat, which is associated with hypertension, altered respiratory mechanics, higher resting heart rate, and may contribute to an increased cardiovascular risk. Physiological parameters, such as heart rate, blood pressure, respiratory rate, and oxygen saturation, can change hours before the occurrence of a clinically relevant adverse event. Thus, physiological parameters can be considered good predictors of clinical deterioration. Obesity is also associated with physical dysfunctions that can impair physical performance. The non-pharmacological therapeutic strategy for the treatment of obesity involves lifestyle modifications, including a healthy diet and regular physical exercise. Whole-body vibration (WBV) exercise, a type of physical activity, has demonstrated benefits in several specific populations, including obese individuals. Objectives: The objective of this study was to evaluate the immediate effects of a single whole-body vibration (WBV) exercise session, consisting of 15 sets, using a vibration platform (VP) with alternating vertical or lateral displacement, on physiological parameters, perceived exertion, strength, and functionality in obese adults. Methods: Seventy-two obese adult participants were randomly divided into three groups (vertical group, alternating lateral group, and placebo group). Physiological parameters were assessed before, during, and after the intervention, in addition to perceived exertion, functionality, and muscle strength. Results: When comparing the results before and after the intervention, the heart rate–pressure product increased significantly in the alternating lateral group (p = 0.005), and heart rate increased significantly (p = 0.0001) and then decreased significantly (p = 0.030) only in the alternating lateral group. Post hoc analysis revealed a significant increase in perceived exertion in the lateral alternation group, from the period before the intervention to the 10th set (p = 0.006) and from the period before to the period after the intervention (p = 0.011). In the vertical group, a significant increase was observed from the period before the intervention to the 10th set (p = 0.020). Conclusions: In conclusion, considering all the findings of this study, whole-body vibration (WBV) exercise promoted some immediate changes in physiological parameters and perception of effort in obese adults. WBV exercise with the alternating vibration platform induced significant fluctuations in heart rate and increased the heart rate–blood pressure product, although with values within the normal range. Perception of effort increased in all groups. Considering the absence of discrepant changes in physiological parameters, impact on the cardiovascular system, and fatigue, the WBV exercise intervention in side-alternating or vertical vibration vibratory platforms can be considered a viable non-conventional exercise option for the obese population.

Background: Post-exercise recovery involves coordinated metabolic restoration and redox rebalancing. Although dietary polyphenols have been proposed to facilitate recovery, the metabolic mechanisms underlying their effects—particularly during the recovery phase—remain insufficiently characterized. This study aimed to investigate how polyphenol supplementation modulates post-exercise metabolic recovery using an integrative metabolomics approach. Methods: We conducted a secondary analysis of publicly available longitudinal human LC–MS metabolomics datasets from exercise intervention studies with polyphenol supplementation. Datasets were obtained from the NIH Metabolomics Workbench and MetaboLights repositories; study-level metadata were used as provided by the original investigators. Global metabolic trajectories were assessed using principal component analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA). Targeted analyses focused on purine degradation intermediates and redox-related metabolites. Correlation-based network and pathway enrichment analyses were applied to characterize recovery-phase metabolic reorganization. Results: Exercise induced a pronounced global metabolic perturbation in both placebo and polyphenol groups. During recovery, polyphenol supplementation was associated with a partial reversion of the metabolome toward the pre-exercise state, whereas placebo samples remained metabolically displaced. Discriminant metabolite analyses identified purine degradation intermediates and oxidative stress-related lipid species as key contributors to group separation during recovery. Polyphenol supplementation attenuated recovery-phase accumulation of hypoxanthine, xanthine, and uric acid and was associated with a sustained suppression of the uric acid-to-hypoxanthine ratio. Network analyses revealed weakened correlations between purine metabolites and oxidative stress markers, along with reduced network centrality of stress-responsive metabolic hubs. Conclusions: These findings indicate that polyphenol supplementation is associated with accelerated metabolic normalization during post-exercise recovery, potentially through modulation of purine-associated oxidative pathways and system-level metabolic network reorganization.

Adam Smith’s The Theory of Moral Sentiments (1759) and The Wealth of Nations (1776) offer a distinctive perspective on moral development that avoids succumbing to the limitations of capitalism and utilitarianism by supporting both moral agency and the importance of enabling structures and systems in commerce. Corruption of moral sentiments cannot be averted by enforcing only mechanical structures and systems of compliance with governance rules, regulations, and disciplinary processes to control employees. Compliance then follows a means-to-an-end logic for maximising profit, which becomes a barrier for autonomous moral development or is even incapable of moral decision-making, as suggested by Hannah Arendt. Smith’s originality lies in grounding this analysis with an affirmative view of human nature and liberty, which enables him to move beyond purely legalistic or moralistic approaches to understand and counter moral failure. Smith offers a distinctive perspective on moral development in commerce, integrating human cognition, moral philosophy, and enabling structural and systemic design that avoids the displacement of responsibility noted by Albert Bandura. For Smith, the corruption of moral sentiments is distorted by the natural need for praise from others at all costs, as opposed to praiseworthy conduct. His remedy is a two-fold process of moral education in which the impartial spectator extends the natural desire for praise to prioritise honour and integrity in behaviour that is praiseworthy. However, moral education also requires a structural social space that is not prescriptive or legalistic to enhance the freedom to develop morally by exercising the choice to strive towards ethical behaviour. In this manner, self-interest enables moral development through natural means that prioritise honourable conduct and perpetuates sympathetic sentiment in which the well-being of others is considered.

Study Objective: This study aimed to examine the effects of a short-term (three times a week for a total of four weeks) low-load elastic exercise program on sarcopenia-related parameters and the contractile properties of the vastus lateralis in twenty older adult women. Methods: All participants underwent assessments for sarcopenia-related parameters, including body composition, strength, and functional performance. Tensiomyography was utilized to evaluate the contractile properties of the vastus lateralis. A paired samples t-test was employed to compare pre-and post-exercise intervention measurements. Results: Except for body weight, all parameters associated with sarcopenia showed a significant difference following low-load elastic exercise program (p < 0.05). Tensiomyography of the vastus lateralis indicated a considerable increase in contraction time after low-load elastic exercise program (p < 0.05); however, there were no significant differences in maximum radial displacement or velocity of contraction. Conclusions: Our findings suggest that a short-term low-load elastic exercise program may be associated with improvements in sarcopenia–related indicators, including muscle strength and muscle contraction characteristics, in older adults, while being time-efficient.

Temporomandibular disorders (TMD) are increasingly prevalent in the adult population. Given the multifactorial and often chronic nature of TMD, the ideal therapeutic approach must be multimodal and personalized, with a preference for conservative treatments. However, standardized protocols combining occlusal devices and biobehavioral therapy for internal derangement (ID) are still lacking. Case Presentation: A 20-year-old male patient presented with bilateral anteromedial reducible disc displacement, with intermittent locking on the right. He reported joint noises, difficulty chewing, and occasional painful mouth opening. A comprehensive diagnostic workup, including clinical, functional, and radiographic evaluations, was performed. The patient underwent a biobehavioral gnathological therapy involving two oral devices: RA.DI.CA. and By-Te ® Reali. The protocol included personalized exercises, patient education, and behavioural counselling. Results. The patient achieved full remission of pain, disappearance of joint noises, and restoration of mandibular function, without dental movement. Pre- and post-treatment MRI and condylography confirmed improved condyle-disc relationships, increased intra-articular space, and better symmetry of movements, particularly on the right. Conclusion. The combined use of RA.DI.CA. and by-Te ® Reali devices, supported by a personalized functional programme, appears effective in managing TMD with ID. Further studies on larger populations are needed to confirm the efficacy and safety of this protocol. Full article

Background/Objectives: The COVID-19 pandemic limited access to in-person physiotherapy, raising concerns about post-operative rehabilitation outcomes. This prospective observational study, without a control group, evaluated whether a self-rehabilitation protocol following a mini-open Learjet procedure influenced short-term clinical outcomes in active military personnel. Materials and Methods: We prospectively enrolled 18 patients (19 shoulders) undergoing mini-open Latarjet between May and October 2020. Patients performed a standardized self-rehabilitation protocol starting on the first post-operative day, with progressive range-of-motion (ROM) exercises added at two weeks. Pain was assessed using the Visual Analog Scale (VAS), ROM was recorded at each follow-up, complications were noted, and patient satisfaction was evaluated at 12 weeks. Results: A total of eighteen patients were prospectively enrolled in the study. At 12 weeks, mean VAS decreased from 1.2 ± 0.6 at week 1 to 0 at week 4 onward. The mean drug consumption was 2.5 ± 0.7 tablets/day only for the first week. Mean assisted forward flexion improved from 155° ± 10° at week 1 to 180° in all patients by week 4. External rotation reached 60° ± 5°at 4 weeks, 75° ± 4° at 8 weeks, and 80° ± 3°at 12 weeks, with no deficits compared to the contralateral side. Internal rotation improved to the T7 level by week 8 and remained stable in week 12. No complications, recurrent instability, or graft displacements were reported. Patient satisfaction at 12 weeks was assessed using a 0–10 numeric rating scale, with a mean score of 9.5 ± 0.4. Conclusions: Implementation of a self-rehabilitation protocol after mini-open Latarjet surgery was associated with favorable short-term outcomes in young military patients, including early recovery, high satisfaction, and absence of complications. Further validation of these findings will require larger, rigorously controlled studies. Full article

Jumping exercises are widely applied in sport performance and conditioning due to their crucial role in enhancing neuromuscular function and lower-limb power. Acute effects related to contractile properties measured by tensiomyography (TMG) remain insufficiently explored. This study aimed to examine the acute effects of two jump types—bilateral countermovement jumps (CMJs) and stiffness jumps (STs)—on the contractile properties of the vastus medialis (VM) and medial gastrocnemius (GM) muscles. Twenty-nine kinesiology students (fourteen males, fifteen females; age 19.4 ± 0.7 years) performed CMJ and ST protocols in a randomized order. Muscle contractile characteristics were measured before and immediately after each protocol and analyzed using a mixed-model repeated-measures ANOVA. Significant pre–post changes were found in both muscles. In the VM, contraction (Tc) and delay (Td) times decreased (p < 0.01), indicating faster responses, whereas relaxation time (Tr) increased and sustain time (Ts) decreased (p < 0.05), suggesting temporary fatigue. Maximal displacement (Dm) increased (p < 0.01), indicating reduced stiffness. In contrast, the GM showed greater responsiveness after stiffness jumps, characterized by shorter Tc and Td (p < 0.01), and reduced endurance after CMJs. These findings highlight muscle specific neuromuscular adaptations and provide practical insights for optimizing warm-up, training, and rehabilitation protocols through targeted jump selection.

Primary mitral regurgitation (PMR) is the most common mitral valve disorder in clinical practice. Although several prognostic indicators derived from resting transthoracic echocardiography (TTE) and exercise stress echocardiography (ESE) are available, patient outcomes remain highly variable, with substantial differences in complication rates and mortality. Identifying individuals at lower cardiovascular risk is therefore clinically relevant, as they represent a large proportion of cases. Current guidelines recommend an integrative approach—combining qualitative, semi-quantitative, and quantitative indices—to determine the timing of intervention, but they do not specifically address risk stratification in low-risk PMR populations. Recent studies have highlighted the potential prognostic value of chest wall configuration, assessed noninvasively using the Modified Haller Index (MHI). Defined as the ratio of latero-lateral thoracic diameter to the antero-posterior (A-P) sternum–spine distance, MHI appears to influence myocardial deformation indices obtained by speckle-tracking echocardiography (STE). Patients with PMR due to mitral valve prolapse (MVP) often show a reduced A-P thoracic diameter caused by sternal depression. Among these, those with an MHI > 2.5 or A-P diameter ≤ 13.5 cm display greater impairment in global and basal strain, particularly in longitudinal and circumferential directions. These abnormalities likely reflect extrinsic geometric constraints and cardiac displacement leading to apparent dyssynchrony rather than intrinsic myocardial dysfunction. A reduced A-P diameter was also independently associated with mitral annular disjunction (MAD) in MVP and emerged as a determinant of impaired strain in this subgroup. In a retrospective cohort of 424 symptomatic MVP patients with moderate MR undergoing ESE, positive tests and exercise-induced severe MR were uncommon. Importantly, an MHI > 2.5 or an A-P diameter ≤ 13.5 cm was associated with a favorable medium-term prognosis, with few adverse cardiovascular events. This narrative, non-systematic review, based on a structured but non-PRISMA literature search, summarizes current evidence on conventional and novel echocardiographic prognostic markers and their implications for risk stratification in PMR. As such, it carries inherent limitations, including potential selection bias, incomplete retrieval of unpublished or negative studies, and reliance on single-center observational data. The findings should therefore be interpreted cautiously and validated through larger, independent, multicenter investigations. Full article

An important aspect of medical rehabilitation using exoskeletons is objective monitoring of the effectiveness of the exercise program. This control is most often manual and relies on the attention of a rehabilitation physician, but advanced rehabilitation systems also use computer vision technology. Topological skeletons generalize large areas of digital images, representing a virtual internal framework of the analyzed object. The patient and the exoskeleton are described either as a set of spatially disparate (but not explicitly related to either the patient or the exoskeleton) topological skeletons, or as branches of a single topological skeleton which does not allow for objective monitoring of joint displacements. A method to solve this problem for medical rehabilitation using an upper-limb exoskeleton is proposed. It includes the following stages: (I) identifying the exoskeleton, as well as upper and lower parts of the patient’s body; (II) independent construction of three topological skeletons (separately for the exoskeleton and for the upper and lower parts of the patient’s body); (III) their integration. This approach allows for accurate, real-time analysis of movements in the upper-limb joints and prompt notification to the rehabilitation physician of any significant deviations in the technique of performing prescribed exercises.
