Use of Gamification for Adult Physical Rehabilitation in Occupational Therapy; A Novel Concept?

AIM: This commentary discusses the concept of 'gamification' as referred to implicitly or explicitly in the occupational therapy literature. Although occasionally noted to be a new frontier for occupational therapy, our analysis suggests that game mechanics and gamification elements are, in fact, a 'road long traveled' by occupational therapists and that gamification evokes the core aims and vision of occupational therapy. Gamification has been implicitly incorporated into the occupational therapy literature for years, and its benefit of enhancing therapeutic outcomes is evident in many instances. We contend that a more explicit use of the term gamification within the occupational therapy literature will lead to a framework in which both practitioners and researchers can structure and evaluate therapeutic outcomes.

Lessons learned from a pediatric powered mobility lending program.

PURPOSE: To evaluate children's characteristics and impact of a powered wheelchair lending program including comparisons of diagnostic sub-groups, and validation of a predictive model of powered mobility proficiency. METHODS AND MATERIALS: This retrospective study included 172 children who participated in the ALYN powered mobility lending program from 3/2009-7/2022. Demographics and functional levels were measured via questionnaires; driving proficiency was evaluated when the wheelchair was returned, and parents and children were interviewed following their participation in the program. RESULTS: Two diagnostic groups were identified: cerebral palsy (CP) (n = 136, median = 9.75 yrs) and other neuromuscular diseases (NMD) (n = 30, median = 5.83 yrs). They differed significantly in the age they commenced PM training, the male/female ratio, walking ability and access mode. Fifty-seven percent of the participants with CP achieved powered mobility proficiency, a rate that was significantly lower than the 73% proficiency found for the NMD group. Four significant predictors were identified: communication, manual wheelchair operation, access mode and go-stop upon request. They predicted proficiency in approximately 80% of cases. Overall feedback from the parents and children indicated that their personal and family's quality of life improved as a result of their child's ability to use a powered wheelchair. CONCLUSIONS: A lending program provides children with opportunities to improve mobility skills in an appropriate powered wheelchair. Children who can communicate verbally, propel a manual wheelchair, use a joystick and go-stop upon request are significantly more likely to become proficient drivers; however, many who were unable to complete these tasks also improved and even became proficient drivers.

Children who are able to engage in verbal communication, propel a manual wheelchair for short distances, use a joystick and go-stop upon request are significantly likely to become a proficient powered wheelchair drivers.Children with cerebral palsy who have greater physical challenges (e.g., cannot walk at all or propel a manual wheelchair) can reach powered mobility proficiency following practice with a powered wheelchair borrowed from a lending program, although at a lower rate than those with other neuromuscular diseases; additional training strategies should be developed to increase the percent success for children with cerebral palsy.A multivariate logistic regression was able to correctly predict whether a child will become proficient driver in 80% of case.Training with a powered wheelchair from the lending program enabled parents to observe their children's independent mobility in their home environment; they reported improvement in the family's quality of life.

Designing Mobile Health Applications to Support Walking for Older Adults.

Physical activity is extremely important at an older age and has major benefits. There is a range of applications that help maintain physical activity. However, their adoption among older adults is still limited. The purpose of the study is to explore the key aspects of the design of mobile applications that support walking for older adults. We conducted a field study with older adults, aged 69-79 years, using a technology probe (a mobile application developed as an early prototype) with the purpose of eliciting requirements for mobile health applications. We interviewed the participants during and after the study period, asking them about their motivation for walking, usage of the application, and overall preferences when using such technologies. The findings suggest that mobile applications that support walking should address a range of walking variables, support a long-term learning process, and enable the user to take control and responsibility for the walk. In addition, we provide design guidelines concerning the motivation for walking and the data visualization that would make technology adoption easier. The findings from this study can be used to inform the design of more usable products for older users.

Hydrotherapy for Patients With External Fixation: Effect on Infectious Events.

BACKGROUND: Surgery to achieve long bone lengthening and deformity correction in skeletally immature patients is traditionally performed through external fixators. The incidence of infection during treatment is high. Hydrotherapy is highly beneficial during external fixation management, but the infection rates may impact its utilization. The objective of this paper is to document the incidence and duration of infection in patients who participated in a full hydrotherapy program when performed under medical supervision and in accordance with strict follow-up protocols. METHODS: In this retrospective study, we documented the key characteristics of patients who participated in hydrotherapy after lower limb external fixation surgery including age, sex, diagnosis and surgery site, the incidence and duration of pin site infections, and the percentage of cases, which were able to comply with a full hydrotherapy protocol. RESULTS: The hydrotherapy pool met all daily water quality metrics. Thirty-four children (19 males and 15 females) had a mean±SD age of 10.9±4.6 years. Of the cases, 80% were unilateral and 20% were bilateral. Diagnoses included congenital hereditary (eg, achondroplasia), congenital nonhereditary conditions (eg, fibular hemimelia), and acquired conditions (eg, traumatic). The location of osteotomy site was quite evenly spread between the femur and the tibia/fibula. Three out of the 34 patients were unable to receive hydrotherapy due to continuous secretions; 2 patients did not miss any sessions. The mean number of treatments was 3 per week. During the entire period, a total of 1200 treatments were performed for these patients with only 32 cancellations (about 3%) due to secretions or other signs of infection. Spearman correlation coefficients showed significantly high correlations between the duration of external fixation and the duration of hydrotherapy. There are no significant correlations between infections and other factors (sex, age segment, whether the problem is unilateral or /bilateral, diagnosis, and duration of treatment). CONCLUSIONS: This is the first report, to our knowledge, that documents the low prevalence of infectious events during hydrotherapy treatment and demonstrates its feasibility. LEVEL OF EVIDENCE: Level III; retrospective, comparative study.

Pediatric powered mobility training: powered wheelchair versus simulator-based practice.

METHOD: Participants included 30 children and adolescents (23 males, 13 females) with cerebral palsy and other neuromuscular diseases, aged 6-18. Data were collected and compared at baseline and after 12 weeks of home-based practice via a powered wheelchair or a simulator. Powered mobility ability was determined by the Powered Mobility Program (PMP), the Israel Ministry of Health's Powered Mobility Proficiency Test (PM-PT) and the Assessment of Learning Powered Mobility (ALP). RESULTS: All participants practiced for the required amount of time and both groups reported a similar user experience. Both groups achieved significant improvement following the practice period as assessed by the PMP and PM-PT assessments, with no significant differences between them. A significant improvement was found in the ALP assessment outcomes for the powered wheelchair group only. CONCLUSIONS: This is the first study, to our knowledge, that compares two different wheelchair training methods. Simulator-based practice is an effective training option for powered mobility for children with physical disabilities aged 6-18 years old, demonstrating that it is possible to provide driving skill practice opportunities safe, controlled environments.

Personalisation of a virtual gaming system for children with motor impairments: performance and usability.

PURPOSE: To demonstrate the potential role of virtual game personalisation for use as a therapeutic modality to improve upper extremity function in children with cerebral palsy (CP). METHODS: The study tested a convenience sample of 60 typically developing children (TD) aged 6-10 years and 20 children with CP aged 7-11 years. Children participated in a single 30-min session when they played the game in accuracy mode (virtual targets are hit as they become progressively larger or smaller) or dwell mode (virtual targets are hit when the users remains on them for progressively shorter or longer durations). These two modes can be played in conventional (non-personalised), personalised and with and without arm weights conditions; weights were used for the TD group in order to ensure that game play would be sufficiently challenging as to require personalisation. We measured performance variables (frequency of changes in game level difficulty and accuracy as measured by percent success of hitting the virtual targets) in each condition and usability variables (self-reported perceived effort and enjoyment). RESULTS: Comparisons between the usability of the conventional and personalised conditions among typically developing children showed that although children self-reported significantly more effort while playing the personalised game, the level of enjoyment remained high (no significant differences between conventional and personalised game play conditions). In addition, comparisons between playing the personalised game with and without weights by typically developing children, indicated that percent success was significantly higher for the game played without weights, suggesting that the system is sensitive to dynamic changes in performance. Comparisons between the TD and CP groups showed that when the game was played in personalised dwell mode (hovering over the target for several seconds) children with CP progressed significantly less quickly through different difficulty levels compared to typically developing children. In contrast, no significant differences were found in accuracy mode (immediate response on target hit), between the TD and CP groups in any of the experimental conditions. DISCUSSION: The personalised game approach was shown to be enjoyable for both groups of users and able to change the level of difficulty in real time. The results suggest that this approach to gaming can provide motor challenges while preserving a high level of enjoyment. CONCLUSION: Personalised virtual therapy shows promise as a tool for upper extremity therapy for children with motor impairment.Implications for RehabiliationIn recent years, there has been an increase in the use of assistive technologies including virtual gaming in the general area of health care and clinical practice.Virtual gaming provides an interactive, real-time experiences that are flexible and ecologically valid ways to improve specific cognitive and motor abilities.Personalisation of virtual games entails dynamic adaptation of the parameters in real time according to the user's functional level).The results have demonstrated that personalised virtual gaming is enjoyable and feasible for typically developing children and children with cerebral palsy.The results suggest that this approach to gaming can provide motor challenges while preserving a high level of enjoyment.

Adaptive control of a wheelchair mounted robotic arm with neuromorphically integrated velocity readings and online-learning.

Wheelchair-mounted robotic arms support people with upper extremity disabilities with various activities of daily living (ADL). However, the associated cost and the power consumption of responsive and adaptive assistive robotic arms contribute to the fact that such systems are in limited use. Neuromorphic spiking neural networks can be used for a real-time machine learning-driven control of robots, providing an energy efficient framework for adaptive control. In this work, we demonstrate a neuromorphic adaptive control of a wheelchair-mounted robotic arm deployed on Intel's Loihi chip. Our algorithm design uses neuromorphically represented and integrated velocity readings to derive the arm's current state. The proposed controller provides the robotic arm with adaptive signals, guiding its motion while accounting for kinematic changes in real-time. We pilot-tested the device with an able-bodied participant to evaluate its accuracy while performing ADL-related trajectories. We further demonstrated the capacity of the controller to compensate for unexpected inertia-generating payloads using online learning. Videotaped recordings of ADL tasks performed by the robot were viewed by caregivers; data summarizing their feedback on the user experience and the potential benefit of the system is reported.

Video modelling as a tool to evaluate self-perception of strategies used by adolescents during daily tasks.

INTRODUCTION: Metacognition is defined as the process of regulating behavior and having self-perception of own performance. An application of video modeling (VM) was used as a technological solution for assessing self-perception in daily situations among typical adolescents, compared to parental reports and to an objective performance-based assessment. METHOD: One hundred and three adolescents (30 boys, 73 girls, mean age =15.1, SD = 1.9), viewed five clusters of videotaped scenarios of teen actors performing daily activities entailing strategy use. Half of the scenarios were classified as "Type A" indicating a more organized approach to accomplishing a task, the other half were "Type B" scenarios indicated a less organized approach to accomplishing the same tasks. Participants were asked to choose the scenarios that best represent their own daily performance using the VM application. The participants then completed the WCPA, an executive function (EF) performance-based assessment. Their parents completed the BRIEF as an indication of EF behaviors in the home environment. RESULTS: 46% of the adolescents associated their performance with a less organized approach yet parental reports indicated adaptive daily performance and their ability to complete the WCPA was as correct as it was for the 56% of participants who associated their performance with a more organized approach. CONCLUSIONS: Unexpectedly, the participants who associated their ability as less organized presented successful behaviors in the home environment and successfully performed the WCPA. Therapists should be aware that clients may achieve success in daily tasks even though they may cope with cognitive challenges in unexpected ways.Implication for rehabilitationTherapists may expect adolescent clients to approach tasks in a variety of ways, using different strategies for coping with everyday cognitive challenge.Therapists need to acknowledge that there is no ideal strategy that provides a solution for all individuals.Mediating a guided discovery of strategies through use of VM technology may customize intervention for each client's needs, assuring a client-centered approach and may encourage a collaboration of therapists and clients in search for the strategies that work best for them.

Reliability and validity of pediatric powered mobility outcome measures.

PURPOSE: To determine the intra-rater and inter-rater reliability of the Powered Mobility Program (PMP) and the Israel Ministry of Health Powered Mobility Proficiency Test (PM-PT); to test inter-rater reliability of the Assessment of Learning Powered Mobility (ALP) tool; to determine the convergent validity of these measures for children with physical disabilities. MATERIALS AND METHODS: Participants included 30 children (mean 10 years, 6 months [SD 3 years, 7 months]; range: 6-18 years) with cerebral palsy and other neuromuscular disorders. Participants were non-proficient powered wheelchair drivers. Two blinded raters assessed the driving ability by viewing videos of the participants twice as they drove a pre-designed route at ALYN Hospital, Israel. They were assessed via the PMP, ALP and PM-PT outcome measures. Intra-class correlation coefficients (ICC2,1) were used to test intra-rater and inter-rater reliability and Spearman correlation coefficients were used to assess convergent validity. RESULTS: The PMP intra-rater reliability revealed ICCs2,1 of coefficients were 0.97/0.98 for both raters. For the PM-PT the ICC2,1 was 0.89/0.96 for both raters. The PMP inter-rater reliability ICC2,1 was 0.94/0.87 for the two tests, for the PM-PT the ICC2,1 was 0.91/0.87 for the two tests and for the ALP the ICC2,1 was 0.83. The convergent validity between the PMP and the PM-PT was rs=0.96, between the PMP and ALP was rs=0.89 and between the PM-PT and ALP was rs=0.87. CONCLUSIONS: The PMP and PM-PT intra and interrater reliability were good to excellent, the ALP inter-rater reliability was good and the convergent validity between all three measures was good to excellent.Implications for rehabilitationThere is evidence of validity and reliability for three tests of powered wheelchair proficiency (PMP, PM-PT and ALP).Children using powered mobility, aged 6-18 years, now have outcome measures with empirical evidence that was previously lacking.When time for assessment is limited, the shorter PM-PT can be used instead of the more comprehensive PMP.

Proximal and distal movement patterns during a graphomotor task in typically developing children and children with handwriting problems.

BACKGROUND: Therapists specializing in handwriting difficulties in children often address motor problems including both proximal and distal movements in the upper extremity. Kinematic measures can be used to investigate various aspects of handwriting. This study examined differences in movement patterns in proximal and distal joints of the upper extremity during graphomotor tasks between typically developing children with and without handwriting problems. Additionally, it explored relationships between movement patterns, speed, and legibility of writing. METHODS: Forty-one children, aged 7-11 years, were assessed with the Aleph Aleph Ktav Yad Hebrew Handwriting assessment and the Beery Test of Visual Motor Integration and, based on their scores, were divided into a research group (with handwriting difficulties) and a control group (without handwriting difficulties). Upper extremity joint movement patterns were analyzed with a motion capture system. Differences in the quality of shapes traced and copied on a graphics tablet positioned horizontally and vertically were compared. Between-group differences and relationships with speed and legibility were analyzed. RESULTS: In both groups, there was greater movement in the distal compared to the proximal joints, greater movement when performing the task in a horizontal compared to a vertical plane, and greater movement when tracing than copying. Joint movements in the arm executed scaled-down versions of the shapes being drawn. While the amount of joint displacement was similar between groups, children in the research group showed greater dissimilarity between the drawn shape and the shape produced by the proximal joints. Finally, the drawing measure on the tablet was a significant predictor of legibility, speed of writing, visual motor integration and motor coordination, whereas the dissimilarity measure of joint movement was a significant predictor of speed of writing and motor coordination. CONCLUSIONS: This study provides support for the role of the distal upper extremity joints in the writing process and some guidance to assist clinicians in devising treatment strategies for movement-related handwriting problems. While we observed differences in proximal joint movements between the children with and without handwriting difficulties, the extent to which they are responsible for the differences in drawing quality remains to be determined. Further studies should use a similar methodology to examine additional tasks such as drawing shapes of varying sizes.

Lessons Learned during a Naturalistic Study of Online Treatment for Pediatric Rehabilitation.

The COVID-19 pandemic forced many health care providers to modify their service model by adopting telehealth and tele-rehabilitation with minimal time to plan for its execution. ALYN-Pediatric Rehabilitation Hospital in Jerusalem, Israel, responded with alacrity by providing a broad range of rehabilitation services to young people via online therapy during the first 5 months of the pandemic. The objectives of this naturalistic study were: (1) to monitor usage and user experience of online rehabilitation provided to young people receiving out-patient sessions of physical therapy, occupational therapy, speech and language therapy and psychology and (2) to consider the advantages and disadvantages of retaining this model of online treatment in full or in part post-COVID-19. The online rehabilitation treatment program was provided to 147 young people, aged 3 months to 20 years (mean 8.5 y; SD 5.3), and monitored and evaluated via data from the medical records as well as interviews, questionnaires and focus groups. The results use descriptive and inferential statistics to analyze data on the types and frequencies of therapy provided to 147 young people. Over a five month-period, 2392 therapy sessions were provided, 61 therapists from four disciplines were involved and 56.4% of the young people received two or more types of therapies via online rehabilitation. A repeated measures ANOVA showed significant differences over time per therapy. Feedback and recommendations about the process from therapists, parents and young people were collected during two focus groups of the professional staff (n = 12), parents and young people (parents n = 5, young people n = 3). Tele-rehabilitation services were perceived to be beneficial and effective by the great majority of young people, their parents and the healthcare professionals. The results are discussed within the context of conventional therapy as well as in comparison to reports of other online services for similar populations. We conclude that a hybrid approach in which in-person therapy sessions are coordinated with synchronous, online sessions, will provide a best-case fit for young people with chronic disabilities.

Self-Feeding Kinematics in an Ecological Setting: Typically Developing Children and Children With Cerebral Palsy.

Assessment of self-feeding kinematics is seldom performed in an ecological setting. In preparation for development of an instrumented spoon for measurement of self-feeding in children with cerebral palsy (CP), the current work aimed to evaluate upper extremity kinematics of self-feeding in young children with typical development (TD) and a small, age-matched group of children with CP in a familiar setting, while eating with a spoon. METHODS: Sixty-five TD participants and six children diagnosed with spastic CP, aged 3-9 years, fed themselves while feeding was measured using miniature three-dimensional motion capture sensors (trakStar). Kinematic variables associated with different phases of self-feeding cycle (movement time, curvature, time to peak velocity and smoothness) were compared across age-groups in the TD sample and between TD children and those with CP. RESULTS: Significant between-age group differences were identified in movement times, time to peak velocity and curvature. Children with CP demonstrated slower, less smooth self-feeding movements, potentially related to activity limitations. CONCLUSIONS: The identified kinematic variables form a basis for implementation of self-feeding performance assessment in children of different ages, including those with CP, which can be deployed via an instrumented spoon.

Exploring hand dexterity in children with myelomeningocele.

PURPOSE: To assess hand dexterity in children with myelomeningocele (MMC) and to explore factors related to hand dexterity in these children. METHODS: Ninety-four children with myelomeningocele, aged 4 to 18 years, were assessed. Demographic characteristics, disease factors, visual perception (Beery test of Visual Motor Integration), cognition (WeeFunctional Independence Measure), and self-care (Pediatric Evaluation of Disability Inventory) were assessed in relation to the Nine-Hole Peg Test (9HPT) for hand dexterity using Spearmen correlations and linear regressions. RESULTS: The children's performance on the 9HPT in both hands was significantly slower than the norms for their age groups. Children without a shunt showed significantly better function in both hands (p = .005) than those with a shunt. Factors most related to hand dexterity were neurological spinal level of MMC, presence of shunt, age, cognitive ability, and years of mother's education. CONCLUSION: Children with MMC appear to have poorer hand skills than typically developed children, which was related to pathology as well as functional and environmental factors. When addressing hand dexterity in children with MMC, it is important that rehabilitation professionals continue to work with these children as they get older, and put greater emphasis on parent education using materials that are adapted to varying educational levels.

Effect of Age on the Touchscreen Manipulation Ability of Community-Dwelling Adults.

Assessment of touchscreen manipulation skills is essential for determining the abilities of older individuals and the extent to which they may benefit from this technology as a means to enhance participation, self-esteem, and quality of life. The aim of this study was to compare the touchscreen manipulation ability between community-dwelling older adults and middle-aged adults using a newly developed Touchscreen Assessment Tool (TATOO) and to determine the usability of this instrument. Convenience samples of two age groups were considered, one including 28 independent community-living older adults aged 81.9 ± 4.2 years with intact or corrected vision and with the abilities to walk independently with or without a walking aid and to understand and follow simple commands, and the other including 25 healthy middle-age adults aged 53.4 ± 5.9 years. The usability assessment was conducted during a single session using the System Usability Scale (SUS). Older adults demonstrated poorer touchscreen skills compared to middle-aged adults. Previous experience in manipulating a smartphone by the older adults did not affect their performance. The SUS results indicated good usability of the TATOO by both age groups. The TATOO shows promise as a user-friendly tool for assessing the specific skills needed to operate touchscreens. The outcomes of this study support the suitability of touchscreen devices and applications as well as the need for adapted accessibility for older adults. Researchers and clinicians will benefit from the availability of a rapid, low-cost, and objective tool to assess the skills required for touchscreen use.

Performance in complex life situations: effects of age, cognition, and walking speed in virtual versus real life environments.

BACKGROUND: Virtual reality (VR) enables objective and accurate measurement of behavior in ecologically valid and safe environments, while controlling the delivery of stimuli and maintaining standardized measurement protocols. Despite this potential, studies that compare virtual and real-world performance of complex daily activities are scarce. This study aimed to compare cognitive strategies and gait characteristics of young and older healthy adults as they engaged in a complex task while navigating in a real shopping mall and a high-fidelity virtual replica of the mall. METHODS: Seventeen older adults (mean (SD) age = 71.2 (5.6) years, 64% males) and 17 young adults (26.7 (3.7) years, 35% males) participated. In two separate sessions they performed the Multiple Errands Test (MET) in a real-world mall or the Virtual MET (VMET) in the virtual environment. The real-world environment was a small shopping area and the virtual environment was created within the CAREN™ (Computer Assisted Rehabilitation Environment) Integrated Reality System. The performance of the task was assessed using motor and physiological measures (gait parameters and heart rate), MET or VMET time and score, and navigation efficiency (cognitive performance and strategy). Between (age groups) and within (environment) differences were analyzed with ANOVA repeated measures. RESULTS: There were no significant age effects for any of the gait parameters but there were significant environment effects such that both age groups walked faster (F(1,32) = 154.96, p < 0.0001) with higher step lengths (F(1,32) = 86.36, p < 0.0001), had lower spatial and temporal gait variability (F(1,32) = 95.71-36.06, p < 0.0001) and lower heart rate (F(1,32) = 13.40, p < 0.01) in the real-world. There were significant age effects for MET/VMET scores (F(1,32) = 19.77, p < 0.0001) and total time (F(1,32) = 11.74, p < 0.05) indicating better performance of the younger group, and a significant environment effect for navigation efficiency (F(1,32) = 7.6, p < 0.01) that was more efficient in the virtual environment. CONCLUSIONS: This comprehensive, ecological approach in the measurement of performance during tasks reminiscent of complex life situations showed the strengths of using virtual environments in assessing cognitive aspects and limitations of assessing motor aspects of performance. Difficulties by older adults were apparent mainly in the cognitive aspects indicating a need to evaluate them during complex task performance.

Comparing children's driving abilities in physical and virtual environments.

PURPOSE: To compare children's driving abilities in a physical and virtual environment and to validate the McGill Immersive Wheelchair Simulator (MiWe-C) for the use of children with disabilities. MATERIALS AND METHODS: Participants included 30 children (17 males, 13 females; mean age 14 y 1 mo, [SD 3 y 6 mo]; range: 5-18 y) with cerebral palsy, neuromuscular disease and spinal cord injury. All children were proficient drivers with more than 3 months' experience, who had their own powered wheelchairs. Participants drove a 15-minute physical route and high-fidelity simulation of that route in a counterbalanced order. Performance of the two routes was compared using the 32 item Powered Mobility Programme (PMP). Differences between the driving modes were analyzed with the non-parametric Wilcoxon signed-rank test. Significance was set at α = 0.05. RESULTS: The scores for the total PMP score as rated during both simulator wheelchair driving and during physical driving were very high (M = 4.90, SD = 0.20; M = 4.96, SD = 0.12, respectively) with no significant difference between them (z= -1.69, p = .09). Five out of the 32 PMP tasks showed significant differences between driving modes (narrow corridors, crowded corridors, doorway, sidewalks), with higher scores for the physical driving mode. CONCLUSIONS: Having a validated powered mobility simulator for children provides a viable option for an additional practice mode. The MiWe-C simulator is affordable and a user-friendly simulator that can be used anywhere including at home and in school. Children can be independent when practicing even if they are not yet proficient drivers since continual adult assistance is not needed.Implications for rehabilitationHaving a validated powered mobility simulator for children provides a viable option for an additional practice mode.The MiWe-C is now validated to be used with children 5-18 years with physical disabilities.The MiWe-C is one of the few options for children to practice outside of a research environment.

DataSpoon: Validation of an Instrumented Spoon for Assessment of Self-Feeding.

Clinically feasible assessment of self-feeding is important for adults and children with motor impairments such as stroke or cerebral palsy. However, no validated assessment tool for self-feeding kinematics exists. This work presents an initial validation of an instrumented spoon (DataSpoon) developed as an evaluation tool for self-feeding kinematics. Ten young, healthy adults (three male; age 27.2 ± 6.6 years) used DataSpoon at three movement speeds (slow, comfortable, fast) and with three different grips: "natural", power and rotated power grip. Movement kinematics were recorded concurrently using DataSpoon and a magnetic motion capture system (trakSTAR). Eating events were automatically identified for both systems and kinematic measures were extracted from yaw, pitch and roll (YPR) data as well as from acceleration and tangential velocity profiles. Two-way, mixed model Intraclass correlation coefficients (ICC) and 95% limits of agreement (LOA) were computed to determine agreement between the systems for each kinematic variable. Most variables demonstrated fair to excellent agreement. Agreement for measures of duration, pitch and roll exceeded 0.8 (excellent agreement) for >80% of speed and grip conditions, whereas lower agreement (ICC < 0.46) was measured for tangential velocity and acceleration. A bias of 0.01-0.07 s (95% LOA [-0.54, 0.53] to [-0.63, 0.48]) was calculated for measures of duration. DataSpoon enables automatic detection of self-feeding using simple, affordable movement sensors. Using movement kinematics, variables associated with self-feeding can be identified and aid clinical reasoning for adults and children with motor impairments.

Effect of age on spatial memory performance in real museum vs. computer simulation.

BACKGROUND: Healthy older adults frequently complain on difficulty in recalling the locations of objects of everyday use. Cognitive abilities decline with normal aging; inefficiencies of information processing, as well as deterioration of neuronal structures, may impede the performance of complex cognitive skills such as spatial memory. Extraneous, task-irrelevant cognitive load in real environments is usually high and might interfere with spatial memory abilities of older adults. The purpose of this study was to determine (1) the extent to which older adults maintain their cognitive capacity during a spatial memory task as compared to young adults and (2) whether this capacity is affected by performance of the task in a real environment setting where the cognitive demands are similar to a simulation, but the physical demands (navigating via walking versus via a mouse) vary. METHODS: In the museum, participants physically moved between display stations to locate hidden tokens performing a task in which an ongoing representation of previous searches had to be remembered. A comparable task was implemented via mouse actions on a computer simulation. Seventeen healthy older (60-80 years) and twenty younger (20-45 years) adults performed both tasks in a counterbalanced order. RESULTS: The younger group was superior to the older group in terms of success rate and completion time for both conditions. All participants performed better during the simulated task. The delta between the total performance score in the two settings of the older group was significantly larger as compared to the younger group, suggesting a differential impact of setting on the groups. CONCLUSIONS: Our results highlight the importance and feasibility of experimentation in ecologically relevant settings: differences were found in the way the cognitive performance of older and younger adults was affected by setting. Older adults appear to preserve basic cognitive abilities required for successful performance of object-location memory tasks. However, real museum setting appeared to impose higher demands on the older adults.

Predictive model of proficiency in powered mobility of children and young adults with motor impairments.

AIM: To identify variables that can predict proficiency in powered mobility use for children in young adults. METHOD: Participants included 80 children and young adults (42 males, 38 females; mean age 10y 2mo, [SD 5y 1mo]; range: 2-22y) with cerebral palsy, neuromuscular disease, and spinal cord injury who participated in the ALYN Hospital Powered Mobility Lending Program from 2009 to 2016. Data were collected and compared before and after participation in the program and powered mobility levels were determined by the Israeli Ministry of Health (MOH) Powered Mobility Proficiency Test. Multivariate logistic regression analysis followed by a bootstrapping procedure that was based on 1000 samples were used to determine if the variables were predictive of success on the Israeli MOH Powered Mobility Proficiency Test. RESULTS: Significant variables for predicting success were identified: manual wheelchair propulsion, go-stop voluntarily upon request, and using a joystick. The model was able to correctly identify 80% of the children. INTERPRETATION: Children and young adults with the ability to go-stop upon request, propel a manual wheelchair short distances, and use a joystick to activate the powered wheelchair had a higher chance of becoming proficient. In countries where wheelchair proficiency is a requirement for powered wheelchair procurement, these findings may support policy changes, as they did in Israel. WHAT THIS PAPER ADDS: Using powered wheelchairs offers children earlier and more natural practice to determine driving proficiency. Manual wheelchair propulsion, go-stop voluntarily upon request, and using a joystick were predictors of powered mobility proficiency. More than 80% of children use a joystick with their hand to activate a powered wheelchair.

MODELO PREDICTIVO DE LA COMPETENCIA EN MOVILIDAD MOTORIZADA DE NIÑOS Y ADULTOS JÓVENES CON DEFICIENCIAS MOTORAS: OBJETIVO: Identificar variables que puedan predecir la capacidad de uso de la movilidad motorizada para niños en adultos jóvenes. MÉTODO: Fueron incluidos 80 niños y adultos jóvenes (42 varones, 38 mujeres; edad media 10a 2m, [SD 5a 1m]; rango: 2-22a) con parálisis cerebral, enfermedad neuromuscular y lesión de la médula espinal que participaron en el Programa de Movilidad Motorizada del ALYN Hospital del 2009 a 2016. Los datos se recopilaron y compararon antes y después de la participación en el programa y los niveles de movilidad impulsados ​​se determinaron mediante la Prueba de competencia de movilidad impulsada por el Ministerio de Salud de Israel. Se utilizó el análisis de regresión logística multivariable seguido de un procedimiento de arranque que se basó en 1000 muestras para determinar si las variables eran predictivas de éxito en la Prueba de Competencia de Movilidad Movida por MOH de Israel. RESULTADOS: Se identificaron variables significativas para predecir el éxito: propulsión manual en silla de ruedas, posibilidad de arranque y freno a la orden, y uso de un joystick. El modelo fue capaz de identificar correctamente al 80% de los niños. INTERPRETACIÓN: Los niños y adultos jóvenes que tienen la capacidad de detenerse cuando se lo requiere, que pueden impulsar una silla de ruedas manual a corta distancia y que pueden usar un joystick para activar la silla de ruedas motorizada tienen una mayor probabilidad de convertirse en expertos. En los países donde el dominio de las sillas de ruedas es un requisito para la adquisición de sillas de ruedas motorizadas, estos hallazgos pueden respaldar cambios en las políticas, como lo hicieron en Israel.

MODELO PREDITIVO DE PROFICIÊNCIA NA MOBILIDADE MOTORIZADA DE CRIANÇAS E ADULTOS COM DEFICIÊNCIAS MOTORAS: OBJETIVO: Identificar variáveis que podem predizer proficiência no uso da mobilidade motorizada para crianças e adultos jovens. MÉTODO: Os participantes incluíram 80 crianças e jovens adultos (42 do sexo masculino, 38 do sexo feminino; média de idade 10a 2m, [DP 5a 1m]; variação: 2-22a) com paralisia cerebral, doença neuromuscular, e lesão da medula espinhal que participaram do Programa de Mobilidade Motorizada do Hospital ALYN de 2009 a 2016. Os dados foram coletados e comparados antes e após a participação no programa, e os níveis de mobilidade motorizada foram determinados pelo Teste de Proficiência em Mobilidade Motorizada do Ministério da Saúde (MS) Israelense. Análise de regressão logística multivariada seguida por procedimento e bootstrapping baseado em 1.000 amostras foi usada para determiner se as variáveis eram preditivas do sucesso no Teste de Proficiência em Mobilidade Motorizada do MS Israelense. RESULTADOS: Variáveis significativas na predição de sucesso foram identificadas: propulsão da cadeira manual, capacidade de iniciar e parar voluntariamente quando solicitado, e uso de controle do tipo joystick. O modelo foi capaz de identificar corretamente 80% das crianças. INTERPRETAÇÃO: Crianças e adultos jovens com a capacidade de iniciar e parar quando solicitados, de impulsionar uma cadeira de rodas manual por distâncias curtas, e usar um joystick para ativar a cadeira de rodas tiveram maior chance de se tornar proficientes. Em países em que a proficiência na cadeira é um requisite para solicitar a cadeira de rodas motorizada, estes achados podem dar suporte a mudanças nas políticas empregadas, como ocorreu em Israel.
