Performance of Computerised Self-Reported Medical History-Taking and HEAR Score for Safe Early Rule-Out of Cardiac Events in Acute Chest Pain Patients: The CLEOS-CPDS Prospective Cohort Study

Abstract Objective A simplified version of the History, ECG, Age, Risk factors, Troponin (HEART) score, excluding troponin, has been proposed to rule out major adverse cardiac events (MACE). Computerised history taking (CHT) provides a systematic and automated method to obtain information necessary to calculate the HEAR score. We aimed to evaluate the efficacy and diagnostic accuracy of CHT in calculating the HEAR score for predicting MACE. Methods Prospective study including clinically stable adults presenting with chest pain at the emergency department of Danderyd University Hospital (Stockholm, Sweden), in 2017-2019. Participants entered their medical histories on touchscreen tablets using CHT software. HEAR and HEART scores were calculated from CHT data. 30-day MACE and ACS outcomes were retrieved, and the diagnostic accuracy was assessed. Logistic regression was used to determine the most predictive components of the HEAR score. Results Among 1,000 patients, HEART and HEAR scores could be calculated from CHT data in 648 and 666 cases, respectively, with negative predictive values (95% CI) of 0.98 (0.97–0.99) and 0.99 (0.96–1.00). Two patients with HEAR score <2 experienced a 30-day MACE. The Age (OR 2.75, 95% CI 1.62–4.66) and History (OR 2.38, 95% CI 1.52–3.71) components of the HEAR score were most predictive of MACE. ACS outcomes provided similar results. Conclusions HEAR score acquired by CHT identifies very-low risk patients with chest pain in the ED, safely ruling out ACS and MACE. This highlights the value of computerised history-taking by patients, which may reduce unnecessary tests and hospital admissions. Trial Registration ClinicalTrials.gov NCT03439449.

Abstract B142: The impact of financial toxicity as a barrier to access and participation in early phase clinical trials for underrepresented populations using the COST–FACIT tool

Abstract Background: ASCO has reaffirmed critical role of early phase (EP) clinical trials (CT) in cancer research and treatment that patients (pts) may achieve improvement in quality of life, experience psychological and direct medical benefits. Disparities in access and participation to CT exist and are more profoundly seen in EP CT with challenge of engaging underrepresented populations (UP) in EP CT which are often complex and only available at larger cancer centers in metropolitan areas. NCI’s Create Access to Targeted Cancer Therapy for Underserved Populations (CATCH-UP.2020) helped bring EP CT to UP. To determine the impact of financial toxicity (FT) as a barrier specific to EP CT participation of UP, the validated COST-FACIT tool was used to survey cancer pts undergoing treatment at the University of Kansas Cancer Center. Methods: This study was approved by our Institutional Review Board (Study 00150640). During routine scheduled visits, pts completed COST-FACIT survey on touch screen tablet. A list of validated questions on EP CT awareness, access, and willingness to participate were included in the survey. Pts responded to 12-item COST-FACIT questionnaire describing the relationship between financial stress and treatments (scale 0 to 4). The score was computed using responses captured from COST-FACIT. Based on literature, scores <26 were determined to be higher FT. Two-sided Fisher's Exact Tests were used to test for a significant association at an alpha level of 0.05. UP included racial and ethnic minorities, low socioeconomic status, low education, and rural. Results: Of 108 pts, 101 completed surveys. 45% identified as female and 55% as male. 11.2% 18–35 years (yrs) of age, 13.9% 36 –50 yrs, 24% 51–65 yrs and 54% >65 yrs. 62.4% were white, 17.8% black, and 19.8% others (Asian or Native American). 8.9% completed <12th grade, 23.8% completed high school, 29.7% have some college experience, 22% completed college and 16% have master’s/doctoral degree. COST-FACIT mean score was 25.7 (SD 10.4, r^2 of 0.48) showing significant financial stress. 46% of pts had scores <26. Pts 18-35 yrs (p=0.02), 36–65 yrs (p=0.00), had yearly incomes of >150,000 (p=0.02) or unaware of their yearly income (p=0.05) were more likely to have significant FT. Pts with < 12th grade (14.89%) or some college experiences (34.09%) were likely to have significant FT. Pts identifying as Asian or Native American were more likely to experience FT than white or black. Conclusion: Almost half of our pts suffer from significant FT creating disparities in EP CT access and participation. Data suggest ages 35-65 yrs, low levels of education, and races other than white and black experience higher levels of FT that is a barrier to EP CT participation. These data support our ongoing efforts to bring innovative EP CT to everyone including the VA and our other outreach partners with higher concentrations of UP. Data on rural and health professional shortage areas will be reported during the meeting. This project was supported in part by The University of Kansas Cancer Center P30CA168524.

Accuracy of Reaction Time Measurement on Automated Neuropsychological Assessment Metric UltraMobile.

This observational study examined the accuracy of simple reaction time (RT) measurements on various touchscreen tablet devices using the Automated Neuropsychological Assessment Metric (ANAM) UltraMobile test battery. The study investigated the implications of interpreting ANAM UltraMobile with laptop-based normative data by analyzing the magnitude and variability of RT accuracy across devices. RT accuracy on 10 different tablets was assessed using a photodetector and robotic arm to respond to stimuli at predetermined response times. The recorded RT was compared with the true RT obtained from the robotic arm to calculate the RT error. ANAM UltraMobile recorded slower RTs than the laptop version. Additionally, RT error varied considerably among the 10 tablet models, suggesting psychometrically significant implications that could lead to interpretive errors when using laptop-based normative data. Relative to the RT error from the laptop-based version of ANAM, tablet data from ANAM UltraMobile are significantly slower and exhibit large variability between devices. These differences may have clinically significant implications for the comparability of the two versions. The findings suggest that further research with human participants is needed to assess the equivalence of ANAM UltraMobile with its predecessor.

A Digital Clock Drawing Test on Tablet for the Diagnosis of Neurocognitive Disorders in Older Adults.

The diagnosis of neurocognitive diseases is an important health issue for patients, families and healthcare professionals. The need to develop rapid, high-performance screening tools would improve access to care. The Clock Drawing Test (CDT) is widely used and validated with the older adults, and its digital version is becoming increasingly widespread. We propose to confirm its validity in a population of old patients hospitalized in a geriatric unit, and secondly to verify its performance in comparison with the reference diagnosis made by a specialized team in a memory consultation. CDTs were collected from older hospitalized patients, both in paper form and digitally on a touchscreen tablet. The results show good agreement between the paper and digital versions (kappa coefficient = 0.81). Sensitivity and specificity of the digital CDT were 0.84 and 0.59 respectively for the diagnosis of major cognitive disorders. The corresponding values were 0.72 and 0.59 for the diagnosis of mild neurocognitive disorders. User questionnaires indicate that older participants find the digital tablet easy to use. However, they prefer to use paper, even if they are open to learning how to use the tablet.

The Dual Task Ball Balancing Test and Its Association With Cognitive Function: Algorithm Development and Validation.

Dual task paradigms are thought to offer a quantitative means to assess cognitive reserve and the brain's capacity to allocate resources in the face of competing cognitive demands. The most common dual task paradigms examine the interplay between gait or balance control and cognitive function. However, gait and balance tasks can be physically challenging for older adults and may pose a risk of falls. We introduce a novel, digital dual-task assessment that combines a motor-control task (the "ball balancing" test), which challenges an individual to maintain a virtual ball within a designated zone, with a concurrent cognitive task (the backward digit span task [BDST]). The task was administered on a touchscreen tablet, performance was measured using the inertial sensors embedded in the tablet, conducted under both single- and dual-task conditions. The clinical use of the task was evaluated on a sample of 375 older adult participants (n=210 female; aged 73.0, SD 6.5 years). All older adults, including those with mild cognitive impairment (MCI) and Alzheimer disease-related dementia (ADRD), and those with poor balance and gait problems due to diabetes, osteoarthritis, peripheral neuropathy, and other causes, were able to complete the task comfortably and safely while seated. As expected, task performance significantly decreased under dual task conditions compared to single task conditions. We show that performance was significantly associated with cognitive impairment; significant differences were found among healthy participants, those with MCI, and those with ADRD. Task results were significantly associated with functional impairment, independent of diagnosis, degree of cognitive impairment (as indicated by the Mini Mental State Examination [MMSE] score), and age. Finally, we found that cognitive status could be classified with >70% accuracy using a range of classifier models trained on 3 different cognitive function outcome variables (consensus clinical judgment, Rey Auditory Verbal Learning Test [RAVLT], and MMSE). Our results suggest that the dual task ball balancing test could be used as a digital cognitive assessment of cognitive reserve. The portability, simplicity, and intuitiveness of the task suggest that it may be suitable for unsupervised home assessment of cognitive function.

Cognitive testings on a touch-screen tablet for older adults: A feasibility study

Cognitive testings on a touch-screen tablet for older adults: A feasibility study

Mobile Media Content Exposure and Toddlers’ Responses to Attention Prompts and Behavioral Requests

With personalized touch-screen tablets, young children can choose content and engage in play-like activities. However, tablets may also reduce shared engagement as the action of viewing or touching the screen is often not visible to nearby adults. This may impact communicative gazing and pointing, which is critical to the formation of shared awareness and in turn supports language development. To assess the association of tablet media content with toddlers' responses to joint attention prompts and behavioral requests. This cohort study took place at a behavioral research laboratory and included toddlers who were aged 18 to 32 months with neurotypical development who were recruited from a volunteer and community sample. Toddlers engaged with a real toy or 3 different types of tablet content (ie, viewing video of toy play, playing with a digital toy, or playing a commercial game) while an experimenter delivered joint attention prompts. Data were acquired from June 2021 November XX 2022, and data analysis occurred from January 2023 to May 2024. Main outcomes included child response to joint attention (number of prompts with joint attention response per number of prompts delivered) and child response to behavioral request (ie, the prompt on which the child responded to the behavioral request). Measures included crossed random effects, Wald tests, and likelihood ratio tests. In this study, 63 toddlers were enrolled, and data from 62 were included (31 female [49%]; mean [SD] age, 26.1 [3.4] months; median [IQR] age, 25.0 [18.6-32.6] months). When toddlers were playing a commercial game on a tablet, they responded to fewer joint attention prompts (crossed random effects model, -0.15; 95% CI, -0.24 to -0.06 prompts) and male toddlers took longer to acknowledge a behavioral request (interaction of content and sex, -0.75; 95% CI, -1.36 to -0.17). The negative impact of the tablet game was larger as child age increased (τ = -2.30; 95% CI, -0.05 to 0; P = .03). Greater media use at home was associated with decreased responding to joint attention prompts during the tablet game (ρ = -0.47; P < .001), while better language skills were associated with more joint attention during play with a real toy (ρ = 0.31; P = .02). In this cohort study, a touch-screen tablet game was associated with decreased joint attention among toddlers and they were less likely to respond to a behavioral request. In a laboratory setting, it was difficult for toddlers to engage in social-communicative interactions with adults when using a tablet media device.

Wear + Touch: An Exploration of Wearables for Vibrotactile Feedback During Touchscreen Input

Vibrotactile feedback is known to have a positive impact on the user performance and experience of touchscreen input. Unfortunately, not all touchscreen devices have built-in haptics capabilities, public displays being a notable example, while the design options for vibrotactile feedback on conventional mobile devices, such as smartphones and tablets, are still limited. In this work, we propose leveraging commodity wearable devices, such as smartwatches, rings, and armbands, to enable vibrotactile feedback as closely as possible to the touch point when the touchscreen does not natively support haptics, and to complement existing haptics capabilities when the touchscreen already features them. To this end, we introduce Wear + Touch, a set of four interaction techniques designed to augment touchscreen input with vibrations delivered through wearable devices, from substituting to complementing, extending, and expanding on-screen vibrotactile feedback. We demonstrate Wear + Touch with several practical implementations involving a large touchscreen display, smartphone, tablet, smartwatch, smart ring, and armband as well as a custom wearable device that we designed for vibrations delivered simultaneously on the user’s index finger, wrist, and forearm. We also report empirical results from two controlled experiments involving a total of 40 participants, conducted to understand the multi-faceted user experience of vibrotactile feedback delivered through the Wear + Touch techniques. In the first experiment, we reveal a favorable user experience of vibrations delivered on the index finger, wrist, and forearm, in this order, when the touchscreen lacks haptics capabilities. In the second experiment, we reveal benefits of reinforcing and expanding on-screen vibrations with vibrotactile feedback on the index finger, wrist, and arm, respectively. We use our findings to suggest future work opportunities for combined vibrotactile feedback involving both touchscreens and wearable devices.

A 5-week Digital Intervention to Reduce Attention Problems in Children With ADHD: A Double-Blind Randomized Controlled Trial

Objective: Growing evidence suggests digital interventions may provide neurocognitive benefits for children with ADHD. This study aimed to investigate the efficacy of a digital attention intervention in children with ADHD. Method: In this double-blind randomized controlled trial 55 children with ADHD (5–9 years) were allocated to the intervention (N = 28) or control program (N = 27). Both programs were delivered via touchscreen tablets at home 5 days a week for 5 weeks. The primary outcome was change in the Test of Variables of Attention (TOVA) Attention Comparison Score (ACS) from pre- to post-intervention. Results: Participants who received the intervention had significantly greater improvements in the TOVA ACS from pre- to post-intervention than those in the control (p < .044). No intervention effects were observed on secondary outcomes assessing executive functioning, ADHD symptoms, or functional impairment. Conclusion: Collectively these findings provide insufficient evidence for the implementation of digital attention interventions for children with ADHD.

Association between the use of mobile touchscreen devices and the quality of parent-child interaction in preschoolers

The early use of mobile touchscreen devices (MTSDs), including smartphones and tablets, may reduce the frequency and quality of social interactions between children and parents, which could impact their relationship and have negative consequences on children's socio-cognitive development. In this study, we applied a parental questionnaire and a behavioral observational method in a laboratory setting (free and structured play sessions) to examine the association between preschool MTSD use and the quantity and quality of parent–child relationships. Our findings revealed that preschoolers who regularly use MTSDs (n = 47, aged 4–7 years, engaging in MTSD use for at least 2 h per week) are spending less time with their parents and exhibited lower quality interactions compared to non-users (n = 25). However, shared offline leisure time with parents serves as a protective factor among MTSD-users. Furthermore, our study demonstrated a positive association between parents' and children's media use. The results suggest that preschool MTSD use may have unfavorable effects on parent–child interactions, both in terms of quantity and quality. Alternatively, lower quantity and quality of parent–child interaction may lead to higher MTSD use in the child. Based on the results, the importance of engaging in sufficient offline family interactions besides digital media use should be emphasized to parents of preschoolers, and health organizations and governments should include this in their recommendations and policies concerning childhood digital media use.

The Evolution of Spinal Endoscopy: Design and Image Analysis of a Single-Use Digital Endoscope Versus Traditional Optic Endoscope.

Spinal endoscopy has evolved significantly since its inception, offering minimally invasive solutions for various spinal pathologies. This study introduces a promising innovation in spinal endoscopy-a single-use digital endoscope designed to overcome the drawbacks of traditional optic endoscopes. Traditional endoscopes, despite their utility, present challenges such as fragility, complex disinfection processes, weight issues, and susceptibility to mechanical malfunctions. The digital endoscope, with its disposable nature, lighter weight, and improved image quality, aims to enhance surgical procedures and patient safety. The digital endoscope system comprises a 30-degree 1000 × 1000 pixel resolution camera sensor with a 4.3 mm working channel, and LED light sources replacing optical fibers. The all-in-one touch screen tablet serves as the host computer, providing portability and simplified operation. Image comparisons between the digital and optic endoscopes revealed advantages in the form of increased field of view, lesser distortion, greater close-range resolution, and enhanced luminance. The single-use digital endoscope demonstrates great potential for revolutionizing spine endoscopic surgeries, offering convenience, safety, and superior imaging capabilities compared to traditional optic endoscopes.

TECH preserves global cognition of older adults with MCI compared with a control group: a randomized controlled trial

BackgroundCognitive training using touchscreen tablet casual game applications (apps) has potential to be an effective treatment method for people with mild cognitive impairment (MCI).AimsThis study aimed to establish the effectiveness of ‘Tablet Enhancement of Cognition and Health’ (TECH), a novel cognitive intervention for improving/preserving cognition in older adults with MCI.MethodsA single-blind randomized controlled trial with assessments pre-, post-, and at 6-month follow-up was conducted. TECH entailed 5 weeks of daily self-training utilizing tablet apps, facilitated by weekly group sessions. Global cognition was assessed by the Montreal Cognitive Assessment (MoCA), and specific cognitive components were assessed using WebNeuro computerized battery. Short Form Health Survey (SF-12) assessed health-related quality of life (HRQoL). Intention-to-treat analysis was conducted and the %change was calculated between pre–post and between pre–follow-up. Cohen’s d effect size was also calculated.ResultsSixty-one participants aged 65–89 years were randomly allocated to TECH (N = 31, 14 women) or to standard care (N = 30, 14 women). Pre–post and pre–follow-up MoCA %change scores were significantly higher in TECH than control (U = 329.5, p < .05; U = 294.5, p < .05) with intermediate effect size values (Cohen’s d = .52, Cohen’s d = .66). Forty percent of TECH participants versus 6.5% of control participants achieved a minimal clinical important difference in MoCA. Pre–post between-group differences for specific cognitive components were not found and HRQoL did not change.Discussion and conclusionsTECH encouraged daily self-training and showed to preserve global cognition of older adults with MCI. The implementation of TECH is recommended for older adults with MCI, who are at risk for further cognitive decline.

The Impact of Touch Screen Tablet Caring Games on Empathic Concern and Compassion in Young Children

Tablet apps that simulate caring for virtual characters have gained considerable popularity among preschoolers. These games involve taking care of virtual pets, babies, or distressed characters on touch screens. Although there are claims that these games enhance empathy and prosocial behavior, there is little research on their impact. The two experiments here explored whether playing touch screen tablet games that involve caring for virtual characters had an influence on preschoolers’ compassion and how young children’s emerging theory-of-mind and developing emotional regulation abilities moderate the relationship between these caring games and compassion towards real others. In both experiments, 3 to 6-year-olds were randomly assigned to one of three game conditions (caring, violent, or neutral). Children’s empathic concern and prosocial behavior towards distressed characters were assessed on laboratory tasks and on vignettes after playing the game. Experiment 1 (N = 192) showed that playing a caring game led to higher levels of empathic concern and helping behavior towards a distressed experimenter than violent or neutral games. In Experiment 2 (N = 188), playing a caring game resulted in higher levels of empathy and prosocial behavior towards hypothetical same-aged peers in need, as compared to the violent or neutral game conditions. Compassion after playing the caring game increased the most in children who scored low on theory-of-mind, or who scored high on emotional regulation abilities. These results suggest that playing caring touch screen games lend weight to the assumption that they may promote empathic concern and compassionate behavior towards distressed others in early childhood.

Effect of touch screen tablet use on fine motor functions in children with hemiparetic cerebral palsy: A randomized controlled trial.

Cerebral palsy is the most frequent condition affecting the central nervous system and causing large disability. To determine the impact of touch screen tablet upon fine motor functions in children with hemiparesis. This was a randomized controlled trial involving 60 children, ranging in age from 5 to 7 years old, randomized into two groups: intervention or control group (30 children per group). Both groups were given 12 consecutive weeks of designed fine motor tasks. Additionally, for thirty minutes, the intervention group was given a fine motor exercise program on a touch screen tablet. Upper limb function, finger dexterity and pinch strength were measured pre and post the recommended treatment program using the quality of upper extremity skill test (QUEST), Nine-Hole Peg Test and Jamar hydraulic pinch gauge, respectively. All outcome measures were equivalent between intervention groups at admission (P > 0.05). Significant improvements were found in all assessed variables within the two groups. Meanwhile, the intervention group had significantly higher improvements (P < 0.05) in finger dexterity, pinch strength, and upper limb function when compared with the control groups. Including a touch screen smart tablet application with a specially designed fine motor program is an effective method that helps children with U-CP perform more effectively with their fine motor skills.

Young children’s transfer of learning on a touchscreen tablet is determined by similarities between tasks and between digital contexts

Transfer of learning is influenced by transfer distance, i.e., the degree of correspondence of contexts as well as of the content to be transferred between a main task and a transfer task (Barnett & Ceci, 2002; Klahr & Chen, 2011). A long tradition of research has used either similarity of tasks or similarity of contexts designs to test transfer distance in problem-solving in children. To our knowledge, no study to date has experimentally varied the degree of similarities between tasks and between contexts jointly, which is the aim of this study. In the present study, we varied the degree of similarity between tasks, by presenting different versions of the Tower of Hanoi (ToH), and between digital learning contexts, by presenting different graphical interfaces. One hundred children aged 6 to 7 years old were divided into four conditions, High similarity of tasks/High similarity of contexts (H/H); High similarity of tasks/Low similarity of contexts (H/L); Low similarity of tasks/High similarity of contexts (L/H); Low similarity of tasks/Low similarity of contexts (L/L). Inhibitory control was also measured, as it may be involved in transfer of learning (Clerc, Miller, & Cosnefroy, 2014; Thibaut, French, Vezneva, Gérard, & Glady, 2011). Transfer of the solving procedure was accompanied by a performance decrement in the L/L and H/L conditions, whereas no such decrement was observed in the L/H and H/H conditions, showing the role of the similarity of digital contexts. Furthermore, inhibition scores predicted transfer performance. Results are discussed considering the theoretical framework of similarities between tasks and between contexts, and the role of inhibition.

Touchscreens can promote infant object-interlocutor reference switching

We re-examine whether the type of object played with influences parent-infant joint attention. A within-participants comparison of 24 parent-9-month-old dyads, used head-mounted eye-tracking to measure parental naming and infant attention during play with touchscreen apps on a touchscreen tablet or matched interactive toys. Infants engaged in sustained attention more to the toy than the tablet. Parents named objects less in toy play. Infants exhibited more gaze shifts between the object and their parent during tablet play. Contrasting previous studies, these findings suggest that joint tablet play can be more interactive than with toys, and raise questions about the recommendation that infants should not be exposed at all to such technology.

Using a digital ‘pocket atelier’ for creative teamwork: What is the impact of digital costume sketching on the professional competence of costume designers?

This practice-led research sheds light on the potential for digital sketching in the field of costume design. This project provides an opportunity to advance our understanding of the impact of ongoing digital transformation on costume design processes and other design processes related to sketching and creative teamwork. The material for the research was collected from interviews with Finnish professional costume designers about their costume sketching practices. Interviews concentrated on designers who preferred using digital sketching methods in their process. This study focuses on costume sketching, which is when a costume designer creates a costumed character using tactile sketching techniques on a tablet touch screen. The portable device acts as a digital sketchbook for the costume designer; this study assesses the effects of this digital ‘pocket atelier’ through the lens of professional competence. Professional competence in this context refers to the ability of designers to perform work-related tasks within a creative team, such as expressing and communicating ideas by generating costume sketches. When asked about the impact of digital costume design methods, most participants commented that they have found their own way of expressing ideas and visions through digital means, which has increased their sense of professionalism. They further described the use of digital tools as making them feel more valued as members of a creative team. The research results indicate that the digital transformation of the design process has changed costume designers’ perception of their own skills as better matching the needs of the work environment.

Bridging the Gap of Graphical Information Accessibility in Education With Multimodal Touchscreens Among Students With Blindness and Low Vision

Introduction: Informational graphics and data representations (e.g., charts and figures) are critical for accessing educational content. Novel technologies, such as the multimodal touchscreen which displays audio, haptic, and visual information, are promising for being platforms of diverse means to access digital content. This work evaluated educational graphics rendered on a touchscreen compared to the current standard for accessing graphical content. Method: Three bar charts and geometry figures were evaluated on student ( N = 20) ability to orient to and extract information from the touchscreen and print. Participants explored the graphics and then were administered a set of questions (11–12 depending on graphic group). In addition, participants’ attitudes using the mediums were assessed. Results: Participants performed statistically significantly better on questions assessing information orientation using the touchscreen than print for both bar chart and geometry figures. No statistically significant difference in information extraction ability was found between mediums on either graphic type. Participants responded significantly more favorably to the touchscreen than the print graphics, indicating them as more helpful, interesting, fun, and less confusing. Discussion: Accessing and orienting to information was highly successful by participants using the touchscreen, and was the preferred means of accessing graphical information when compared to the print image for both geometry figures and bar charts. This study highlights challenges in presenting graphics both on touchscreens and in print. Implications for Practitioners: This study offers preliminary support for the use of multimodal, touchscreen tablets as educational tools. Student ability using touchscreen-based graphics seems to be comparable to traditional types of graphics (large print and embossed, tactile graphics), although further investigation may be necessary for tactile graphic users. In summary, educators of students with blindness and visual impairments should consider ways to utilize new technologies, such as touchscreens, to provide more diverse access to graphical information.

Efectividad de una aplicación de telerrehabilitación para tableta en pacientes con fractura de extremo distal del radio

IntroductionTo assess whether, in patients with distal radius fracture feedback-guided exercises performed on a tablet touchscreen reduce healthcare usage and improve clinical recovery, more than the conventional home exercise program prescribed on paper. Material and methodsA multicentre, parallel, two-group, pragmatic, controlled trial with assessor blinding and intention-to-treat analysis. Forty-six patients with distal radius fracture were recruited in Andalusian Public Health System. Participants in the experimental and control groups received the same in-patient physiotherapy sessions. Experimental group received a home exercise program using the ReHand tablet application and control group received an evidence-based home exercise program on paper. The primary outcome was the number of physiotherapy sessions tallied from hospitals data management system. Secondary outcomes included: the face-to-face rehabilitation consultations with a physiatrist, and clinical outcomes such as functional ability, grip strength, dexterity, pain intensity and range of motion. ResultsThe experimental group required fewer physiotherapy sessions (MD: −16.94; 95%CI: −32.5 to −1.38) and rehabilitation consultations (MD: −1.7; 95%CI: −3.39 to −0.02) compared to the control group. ConclusionsIn patients with distal radius fracture, prescribing feedback-guided exercises performed on a tablet touchscreen provided by ReHand reduced number of physiotherapy sessions and rehabilitation consultations.

Experiences of Older Adults with Mild Cognitive Impairment from Cognitive Self-Training Using Touchscreen Tablets.

Background: "Tablet Enhancement of Cognition and Health" (TECH) is a cognitive intervention that includes two components: 5 weeks of daily self-training using puzzle-game apps on a touch screen tablet and weekly group sessions. This study aimed to (i) explore experiences of older adults with mild cognitive impairment (MCI) following their participation in TECH, (ii) identify hindering and enabling factors to self-training, and (iii) describe participants' perceived and objective cognitive changes and examine factors associated with their satisfaction from TECH. Materials and Methods: We used quantitative and qualitative measures; a phenomenological qualitative design using focus groups and interviews of 14 older adults with MCI and a focus group of the TECH facilitators. Satisfaction with TECH, self-training time, and perceived and objective cognitive changes (using the Montreal Cognitive Assessment) were evaluated. Results: Qualitative data were classified into three categories: Memory problems, Hindering and enabling factors to self-training, and Meaningful group sessions. The TECH facilitators reported positive changes, less cognitive complaints, and commitment and satisfaction of the participants. Participants reported overall satisfaction from TECH and performed a median interquartile range of 22.6 (19.9-42.8) self-training hours. Higher satisfaction was correlated with a higher objective cognitive change (r = 0.95, P < 0.01) and less training time (r = -0.91, P < 0.01). Discussion and Conclusions: Participants in the current study actively engaged in daily self-training using touch screen-tablet-puzzle-game and functional apps, driven by both internal and external motivators. Despite the lack of cognitive improvement, they expressed satisfaction with their participation in TECH. Therefore, encouraging older adults to engage in meaningful cognitive stimulating activities is recommended.
