Background: Social media platforms have become important spaces for the circulation and discussion of health information. X (formerly Twitter) is one such space where traditional, complementary, and integrative medicine (TCIM)–related terms circulate in public health discourse. However, longitudinal TCIM-related mention patterns on social media, particularly during the COVID-19 pandemic period, remain poorly documented. Objective: The study aimed to characterize temporal mention patterns of TCIM-related terms on X across English, Spanish, and French between 2015 and 2024, including the COVID-19 pandemic period. Methods: We conducted a retrospective observational infodemiology study using raw, nonnormalized annual mention counts from Brandwatch-indexed public X content in English, Spanish, and French that contained 39 predefined TCIM-related terms from 2015 to 2024. Descriptive analyses summarized cumulative mentions and annual mention counts. Exploratory trend analyses were restricted to the 2015 to 2019 prepandemic period. For each term-language combination, ordinary least squares regression was fitted with annual mention count as the dependent variable and calendar year as the independent variable. Exploratory linear trend signals were retained when R2≥0.70 and an exact permutation test on the slope yielded P≤.05 (120 permutations). Results: Cumulative mentions of the 39 TCIM-related terms totaled 191,994,848 over 2015 to 2024. The most frequently mentioned terms were “yoga” (79,618,183), “meditation” (55,560,372), and “mindfulness” (18,915,377), together accounting for 80.3% (154,093,932/191,994,848) of all mentions. Raw cumulative mentions were predominantly indexed in English (170,100,867/191,994,848, 88.6%) compared with Spanish (17,171,541/191,994,848, 8.9%) and French (4,722,440/191,994,848, 2.5%). Between 2019 and 2020, “meditation” showed the largest absolute increase in raw mention counts (1,935,949/3,627,557, 53.4%), whereas “ayurveda” showed the largest relative increase (400,624/214,901, 186.4%). Exploratory 2015 to 2019 trend analyses identified 14 linear trend signals in English (n=13, 92.9% decreasing; n=1, 7.1% increasing: “intermittent fasting,” 161,584/70,496, 229%), 11 in French (n=5, 45.5% increasing), and 8 in Spanish (3 increasing). “Reiki” and “reflexology” decreased in all 3 languages. Conclusions: Between 2015 and 2024, raw TCIM-related mention counts on X were highly concentrated in a small set of wellness and mind-body labels and were predominantly in English compared with Spanish and French. No sustained aggregate surge was evident in the raw descriptive data during the COVID-19 pandemic period, although some terms such as “ayurveda” showed short-term fluctuations. These findings should be interpreted as platform-specific raw mention patterns, not as evidence of normalized public interest, sentiment, user attitudes, professional practice, or actual TCIM use.

BACKGROUND Over the past decade, the rise of social media has profoundly transformed the ways health information is disseminated and discussed. Social media platforms such as Twitter/X have become key spaces where users can share their experiences and opinions regarding traditional, complementary, and alternative medicines (TCAM). However, trends on social media, particularly during the COVID-19 pandemic, remain poorly documented. OBJECTIVE The study aimed to characterize temporal trends in TCAM-related discourse on X (formerly Twitter) across English, Spanish, and French between 2015 and 2024. METHODS We conducted a retrospective observational analysis of annual mention counts in public X posts in English, Spanish, and French that contained 39 main TCAM-related terms over the 2015-2024 period. Descriptive analyses summarized cumulative mentions. Inferential trend analyses were restricted to the 2015-2019 period and used term-wise ordinary least squares regression. Trends were retained if R² ≥ 0.70 and an exact permutation test on the slope yielded P≤.05 (120 permutations, exhaustive given 5 observations). Uncertainty around 2015-2019 relative changes was quantified using 95% bootstrap percentile confidence intervals. RESULTS Cumulative mentions of the 39 TCAM-related terms totalled 191,994,848 over 2015-2024. The most frequently cited terms were “yoga” (79,618,183), “meditation” (55,560,372), and “mindfulness” (18,915,377), together accounting for 80.3% of all mentions. Cumulative mentions were predominantly in English (88.6%) compared to French (8.9%) and Spanish (2.5%). For example, “yoga” was used 71,203,218 times in English, 7,370,196 in Spanish, and 1,044,769 in French. Annual trajectories showed no order-of-magnitude surges among the top 10 terms; the largest year-to-year increase from 2019 to 2020 was observed for “ayurveda” (+186%). Trend analyses over 2015-2019 identified 14 significant terms in English (13 decreasing; 1 increasing +229% “intermittent fasting”), 8 in Spanish (3 increasing), and 11 in French (5 increasing). The terms “reiki” and “reflexology” decreased in all three languages. CONCLUSIONS Between 2015 and 2024, the text-based analyses related to TCAM on X (formerly Twitter) were highly concentrated in a small set of body-mind practice labels and in English compared to Spanish and French. No peak was observed across the overall TCAM corpus during the COVID-19 pandemic, although isolated terms such as “ayurveda” showed marked short-term increases. The results indicate a relative stability of TCAM-related needs and concerns. These findings reflect mention frequency only and cannot be interpreted as indicators of professional practice or actual consumer use.

De nombreuses théories de l’apprentissage se sont construites à partir d’observations des corps et des objets en coprésence. Au-delà d’une coprésence, c’est un véritable couplage que certains travaux mettent en évidence. À partir de la littérature concernant ce que nous choisissons d’appeler « incorporation d’objets », et de certains résultats d’expérimentations en psychologie et d’observations de type ethnographique, nous nous interrogeons sur trois points : 1. la place des objets dans les apprentissages, notamment dans les apprentissages moteurs ; 2. les étapes du processus d’incorporation ; 3. les liens entre incorporation et expertise. Nous espérons ainsi, à travers cet article aux orientations interdisciplinaires fortes, contribuer à enrichir cette réflexion partagée par de nombreux chercheurs sur les liens entre apprentissage et objets matériels.

Long-range correlations have been evidenced in a number of experiments, generally using overlearned and overpracticed tasks. The authors hypothesized that long-range correlation could represent the byproduct of learning. They analyzed the series of periods produced by a group of expert and a group of novices during prolonged trials on a ski simulator. Results showed a very low variability in expert's series, as compared to novices. Fractal analyses showed that fluctuations were significantly more structured and correlated in experts. These results suggest that learning could be conceived as the progressive installation of complexity in the system.

Lors de la prise de contrôle d’une classe en EPS, des « zones de rencontre » se construisent selon des modèles de rites d’interaction (Goffman, 1974). Elles renvoient à un espace de rencontre entre l’enseignant et ses élèves qui participe de la construction de l’identité professionnelle. La méthodologie comporte un questionnaire (13 questions ouvertes, 20 sujets enquêtés) permettant de modéliser des profils. L’analyse de contenu fait apparaître trois conduites typiques d’enseignants : (le « protecteur », le « transmetteur » et l’« acteur ») s’appuyant sur trois logiques : sociale, corporelle et professionnelle. Les conduites ainsi identifiées dévoilent une dialectique entre la construction du sujet professionnel et celle des rituels de rencontre avec les élèves, dialectique présentant une dimension adaptatrice et créative. Les « zones de rencontre » caractérisent les profils d’enseignants dans l’exercice de leur métier.
