The purpose of this study was to analyze the relationship between the quality and speed of handwriting and the process characteristics of the handwriting of children in the second grade of elementary school considered as a function of age and gender. A sample of 57 children (mean age 7.25 years, SD 0.43) participated in the study. The Concise Assessment Method for Children’s Handwriting (BHK) was used to assess the quality and speed of handwriting. The characteristics of the process of handwriting were assessed using MovAlyzeR® software. The handwriting of boys showed a significantly greater number of strokes and slanted more to the right than the handwriting of girls. Handwriting quality and speed significantly correlated with several process characteristics: the number of strokes, reaction time, duration, relative pen-down duration, average pen pressure, vertical size, horizontal size, road length, and average absolute velocity. This research contributes to the construction of normative values in the process characteristics of the handwriting of elementary school children and provides a promising step towards the early identification of difficulties that can lead to dysgraphia, thus preventing later difficulties in handwriting.

Background/Objectives: Gait performance in aging relies heavily on cognitive resources, yet the extent to which short-term interventions can mitigate dual-task costs in institutionalized populations remains understudied. This study aimed to compare single and dual-task gait performance between older adults with and without suspected cognitive impairment and to evaluate the effects of an 8-week multicomponent exercise program on functional mobility. Methods: Institutionalized older adults (n = 42) were stratified into two groups: suspected cognitive impairment (n = 26) and no suspected impairment (n = 16), based on MMSE and Clock Drawing Test screening. Participants performed the Timed Up and Go (TUG) and Dual-Task TUG (TUG-DT) at baseline and post-intervention. Results: At baseline, the suspected impairment group exhibited significantly poorer performance on both tests (p < 0.001) compared to the non-impaired group. Following the 8-week intervention, the suspected impairment group demonstrated large, significant improvements in both TUG (r = −0.73) and TUG-DT (r = −0.59), whereas the non-impaired group remained stable. Notably, while the single-task TUG showed the greatest responsiveness to the exercise program, the TUG-DT continued to reveal a significant cognitive-motor load. Conclusions: Multicomponent exercise effectively enhances functional mobility in cognitively vulnerable older adults, reversing declines in both single and dual-task conditions. Significance: These findings support the implementation of dual-task screening to unmask latent functional deficits and validate the use of accessible, short-term multicomponent exercise programs as a vital strategy to preserve autonomy in institutionalized older adults.

A significant number of institutionalized children have behavior problems. Socio-emotional skills are fundamental for their adaptation and success throughout life and are usually weakened in this population. Equine-assisted services (EAS) are a form of therapeutic mediation that facilitates and requires the practitioner’s participation, contributing to the promotion of various psychomotor and socio-emotional dimensions. This study was developed during 17 sessions of EAS with a psychomotor intervention, which took place individually and weekly and lasted approximately 45 min, with three institutionalized children. A quantitative and qualitative assessment was carried out before and after the intervention to study the effects of an EAS intervention on socio-emotional competencies in the three institutionalized children. There was an improvement in skills, with an impact on intrapersonal skills and marked improvement in self-regulation and self-control, in addition to an improvement in the intentionality of movement and adequacy of gesture to the context. This type of intervention underlies a renewed educational and therapeutic approach, contributing to mental health promotion in this population.

Background: Handwriting is a hierarchical cognitive–motor activity requiring the integration of motor execution, visuospatial processing, working memory, and executive control. Digital handwriting technology enables simultaneous assessment of process (kinematics) and product (performance outcomes), offering a theoretically grounded approach to detecting cognitive vulnerability in aging. Methods: This study examined whether kinematic handwriting features differentiate institutionalized older adults with and without cognitive impairment and whether these features predict handwriting product performance under varying cognitive–motor demands. Fifty-eight participants (20 cognitively healthy; 38 cognitively impaired), classified using education-adjusted MMSE cutoffs, completed pen-control tasks (DOTS, LINES) and four handwriting-speed tasks (two copy, two dictation) on a digitizing tablet. Nine standardized kinematic variables were analyzed using logistic and multiple linear regression models with correction for multiple comparisons. Results: Pen-control tasks (DOTS, LINES) did not significantly discriminate between the two groups, the handwriting-speed tasks, particularly dictation, revealed significant group differences. Temporal efficiency and stroke organization variables (e.g., Duration, Number of Strokes) significantly contributed to classification in high-demand tasks. Among cognitively healthy participants, associations between kinematic and product measures were limited, suggesting preserved compensatory mechanisms. Conversely, cognitively impaired individuals exhibited stronger process–product coupling, with Start Time, Vertical Size, and Duration significantly predicting handwriting performance in dictation tasks. Conclusion: Handwriting kinematics, especially temporal and stroke-related features, are sensitive indicators of cognitive impairment when assessed under high cognitive–motor load. These findings support the use of digitally mediated handwriting tasks—particularly dictation paradigms—as ecologically valid, low-cost tools for screening and monitoring cognitive decline in older adults.

This article describes the translation and cultural adaptation process of the WRITIC (Writing Readiness Inventory Tool in Context) into European Portuguese. We examined the content and convergent validity, test-retest, and interrater reliability on the norm-referenced subdomain of the Portuguese (PT) WRITIC Task Performance (TP). To establish content validity, we consulted six experts in handwriting. Internal consistency was found with 70 children, test-retest reliability with 65, inter-rater reliability with 69, and convergent validity with 87. All participants were typically developing kindergarten children. Convergent validity was examined with the Beery–Buktenica Developmental Test of Visual-Motor Integration (Beery™VMI-6) and the Nine Hole Peg-Test (9-HPT). On content validity, we found an agreement of 93%, a good internal consistency with Cronbach’s alpha of 0.72, and an excellent test-retest and inter-rater reliability with ICCs of 0.88 and 0.93. Correlations with Beery™VMI-6 and 9-HPT were moderate (r from 0.39 to 0.65). Translation and cross-cultural adaptation of WRITIC into European Portuguese was successful. WRITIC-PT-TP is stable over time and between raters; it has excellent internal consistency and moderate correlations with Beery™VMI-6 and 9-HPT. This analysis of the European Portuguese version of WRITIC gives us the confidence to start the implementation process of WRITIC-PT in Portugal.
