Comparison of short-stretch bandage and long-stretch bandage for post-traumatic hand edema
Full text linkIntroduction and importance: Hand edema is a common post-surgical or traumatic complication in orthopedic
patients, necessitating effective treatment interventions. This study aimed to investigate the effects of two
different types of bandages, along with finger flexion exercises, on managing hand edema.
Case presentation: Our orthopedic patients with post-surgical or traumatic hand edema and three non-edematous
hands were enrolled in the study. A mixed model effect with fixed factors of time (pre-post) and bandage type (M,
C, N), and random factors of hand, edema, fingers, and phalanges was applied. The bandage types were circular
with short elastic bandage (M) and circular with elastic bandage (C). Finger flexion exercises involved alternating
contractions of extrinsic and intrinsic flexors. Randomization ensured unbiased allocation to bandage types.
Clinical discussion: The M bandage demonstrated a significant reduction in hand edema by effectively moving free
fluids, reinforcing tissue hydrostatic pressure, and facilitating venous and lymphatic flow. On the other hand, the
C bandage did not produce significant pre-post differences in hand circumference.
Conclusions: The combination of a circular bandage with finger flexion exercises shows promise in reducing hand
edema in orthopedic patients. Particularly, the stiff bandage M exhibited superior efficacy compared to the
elastic one C in reducing hand circumference. These findings provide valuable insights for clinical practice,
offering an effective strategy for managing hand edema and promoting better patient outcome

Introduzione alla Statistica per Psicologia Settima Edizione
No full textNel Manuale sono trattati i fondamenti della statistica con particolare attenzione all'applicazione per la ricerca in psicologia. Sono approfondite le tecniche statistiche di base sia in campo descrittivo e inferenziale con esempi di applicazioni e riferimenti al software SPSS. Il manuale riporta in modo dettagliato sia la logica di base che il procedimento per test statistici semplici quali i t test e test dei ranghi fino a test più complessi come l'analisi della varianza e la regressione lineare
Il ruolo dei movimenti oculari nella percezione del movimento
No full textLa letteratura non ha ancora chiarito quale sia il ruolo dei movimenti oculari nella percezione del movimento in assenza di possibilità di inseguimento degli stimoli. In questo studio abbiamo registrato i movimenti oculari di quaranta partecipanti durante un compito di «motion coherence» che impediva l’inseguimento, per indagare se e in che modo i movimenti oculari contribuissero all’accuratezza nella percezione del movimento. L’abilità di discriminare la direzione del movimento è stata studiata in funzione della velocità dei movimenti oculari misurati mediante videoculografo a infrarossi. I risultati confermano che la velocità dei movimenti oculari predice l’accuratezza nella percezione del movimento. Ciò fa supporre che sussista un processo iniziale che accomuna i sistemi atti a governare i movimenti oculari e la percezione del movimento

Italian adaptation of the System Usability and Acceptance Model scale: application to MatriKS a new digital test for fluid intelligence assessment
No full textThe perceived ease of use and attitude towards new technologies are particularly
relevant for the effectiveness and implementation of new digital neuropsychological tests.
Nevertheless, to date there are no instruments specifically targeted for developmental
age that encompass both the features of usability and acceptability. The present work
aims to describe the psychometrics properties of the Usability and Attitude Scale (UAS),
an Italian adaptation of the System Usability Scale (SUS; Brooke,1995) and Technology
Acceptance Model Scale (TAM; Venkatesh & Bala, 2008; Davis, 1989). Furthermore, the
study aimed at assessing the usability and attitude of MatriKS, a new computerized test
for the evaluation of fluid intelligence. The UAS was administered to a sample of 1,239
participants aged 4 to 70 (47% males and 53% females, M=19.43, SD=16.86) of the
general population. All participants completed different versions of MatriKS according to
their age and then completed the UAS. Overall, UAS showed good content validity and
internal consistency. Moreover, the results obtained using the Curved Grading Scale
Method (CGS; Sauro & Lewis, 2012;2016), confirmed the positive reception of MatriKS,
indicating that test-takers perceived the assessment as a positive experience.
Specifically, the usability resulted “excellent” for the version tailored to the younger
population, while the usability score of the other version resulted between “sufficient” and
“good”. Concerning the acceptability perceived by participants, the results obtained with
the CGS method, confirm positive ratings like those found for usability. In conclusion, the
UAS showed good psychometric properties and feedback provided by test-takers
suggest that the MatriKS is promising and deserves further research
AdapTol: un nuovo strumento computerizzato per discriminare tra sviluppo tipico e disturbi del neurosviluppo
No full textNumerosi studi dimostrano che i disturbi del neurosviluppo (DNS) sono caratterizzati da alterazioni delle funzioni esecutive (FE). Esistono, tuttavia, evidenze contrastanti, spiegate dalla forte eterogeneità e variabilità interindividuale. In questo scenario, gli strumenti digitali permetterebbero di valutare campioni ampi, rappresentando meglio tale eterogeneità.
AdapTol è un nuovo strumento per valutare le FE in modalità computerizzata. Questo studio preliminare indaga la capacità di AdapTol di discriminare tra popolazioni con DNS e a sviluppo tipico (TD). Sono stati valutati 719 bambini tra 4 e 14 anni (374 femmine) mediante AdapTol, di cui 61 con DNS. L’accuratezza ed il numero di violazioni sono state analizzate mediante analisi della varianza multivariata, con diagnosi di DNS come fattore tra i soggetti ed età come covariata. I risultati mostrano che il gruppo DSN ha prestazioni significativamente inferiori per l’accuratezza (F=8.4; p=.004) ma non per il numero di violazioni (F=1.5; p=.22) rispetto ai TD; l’età ha un effetto marginalmente significativo soltanto per l’accuratezza, mostrando un miglioramento con l’aumentare dell’età (F=7.1; p=0.08).
Complessivamente, i bambini con DNS riescono a completare le prove, suggerendo una buona usabilità di AdapTol. Inoltre, nonostante la variabilità di prestazione nella popolazione clinica, AdapTol sembra un efficace strumento per discriminare tra popolazione clinica e TD
Developmental trajectories of accuracy and type of errors in Fluid intelligence assessment as detected by a new digital tool: MatriKS.
No full textFluid intelligence (FI) is the ability to think logically and solve problems in new situations. It is generally assessed through nonverbal reasoning tests (e.g.,Raven’s Matrices). Studies assessing FI through standard tests highlighted that this skill improves during development. Moreover, prior research showed that the matrices’ complexity is influenced by several factors - such as the number of elements, perceptual characteristics, rules number, and complexity. Yet, to date few evidence exists on changes in different types of errors during development.
This study aims to evaluate the developmental trajectories of MatriKS, a new digital tool for the evaluation of FI. We analysed the total accuracy and the different types of errors (i.e., repetition, wrong principle, difference, incomplete correlate). MatriKS was administered to N=590 typically developing participants (males = 311, females = 279) aged 4-11 years old (M = 8.39, SD = 2.19).
Results of generalised linear model (glm) on accuracy showed that children’s performance significantly improves with age (z = -29.06, p<0.001). Results of glm on error types showed an overall decrease of errors number with age (z = -23.58, p<.001). To better investigate the relation between changes in the different types of errors and age, we divided the sample in 2 years-step age groups and performed an ANOVA. Results showed significant main effects of error type (F(5,561)=30,91, p<0.001) and age (F(4,561)=89.64, p<0.001), as well as a significant interaction (F(11,1300)=5.94, p<0.001). Specifically, the number of errors significantly decreases with age in all the distractor types, but not in “Difference”.
In conclusion, MatriKS proves to be a tool capable of detecting differences based on age, both on accuracy and error types. Information about the characteristics of errors and how they change with age is pivotal for planning targeted and individualized interventions in several clinical populations
