Home Videos for Remote Assessment in Children with Disabilities: A Scoping Review

Background: Analysis of parent-provided home videos is a mode of technology that can facilitate a telehealth assessment, allowing observation of function in the child's natural home environment. This scoping review investigated areas of use of home videos for functional assessment by health professionals with a pediatric population with disabilities. Methods: Four databases were searched for articles in which parent-provided home videos were employed by health professionals for functional assessment in children with disabilities. Articles published from 2013 to 2023 were included in the review if they met the inclusion criteria, and the data were extracted into an Excel file. Results: After screening 3,019 articles, 30 articles were included in the data extraction. The majority of studies utilized home videos for diagnosis of autism, followed by assessment of motor development in infants. Studies found that using home videos for assessment is feasible and empowers parents. The validity and reliability of various home video platforms were demonstrated. Conclusions: Analysis of home videos can aid in making a timely diagnosis for prompt intervention, and can be used to assess various body functions, interchangeable with a live clinic assessment. It is important to provide parents with clear instructions when using this method. Future studies are necessary to determine whether parent-provided home videos can be utilized by a multidisciplinary team to assess diverse factors, including activity, participation, and the environment, in a variety of populations of children with disabilities, thus extending services beyond the physical borders of the clinic.

Development of a new tool: progression of paediatric powered mobility- 3PM

PURPOSE

To develop a tool to assess the progression of powered mobility skills for children and determine its psychometric properties.

METHOD

A three-phase, the mixed-method design included: I) conceptualisation based on international specialists' input through a focus group or interview to generate initial items; II) tool development using a two-round Delphi survey and III) evaluation of psychometric properties from eight video recordings of children. The Progression of Paediatric Powered Mobility (3PM) was validated via Intraclass correlation coefficients (ICC) calculated from conventionally powered mobility assessments: the Powered Mobility Program, the Assessment of Learning Powered Mobility tool, and the Powered Mobility Proficiency test.

RESULTS

Content derived from 20 clinical experts led to the development of the first version consisting of 19 demographic and 61 driving skill items. Following two Delphi rounds, the final tool included 14 demographic and 41 driving skill items. Internal consistency was excellent (Cronbach alpha = 0.96) as was the inter-rater reliability (ICC = 0.96, 95% confidence interval = 0.95-0.96). Pearson correlation coefficients between the 3PM and other PM assessments demonstrated good convergent validity.

CONCLUSION

The 3PM, created through international collaboration with experts in PM, has excellent psychometric values as a valid measure that can be used reliably to assess children's powered mobility skills.Implications for rehabilitationThe 3PM reflects the three stages of powered mobility development: exploratory, operational, and functional stages.Input from clinical experts in PM mobility contributed to the identification of the key driving skills important to include in the 3PM.A reliable and valid tool can facilitate assessment and tailored intervention in paediatric powered mobility.

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.

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.

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.

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.

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.

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.

A new locus for autosomal dominant posterior polar cataract in Moroccan Jews maps to chromosome 14q22-23

BACKGROUND

Posterior polar cataract is a clinically distinctive opacity located at the back of the lens. It is commonly acquired in age related cataract, and may infrequently occur in pedigrees with congenital cataract. To date, five loci for autosomal dominant congenital posterior polar cataract have been identified. These include two genes, CRYAB and PITX3, on chromosomes 11q and 10q respectively, and three loci with as yet unknown genes on chromosomes 1p, 16q and 20p.

PURPOSE

To find the chromosomal location of a gene causing autosomal dominant congenital posterior polar cataract in three Moroccan Jewish families.

METHODS

A whole genome scan was performed using microsatellite markers spaced at approximately 10 cM intervals. For fine mapping, five additional microsatellite markers were genotyped. Two-point lod scores were calculated using MLINK software, from the LINKAGE program package. After linkage was established, several positional candidate genes were assessed by PCR based DNA sequencing.

RESULTS

The new cataract locus was mapped to an 11.3 cM interval between D14S980 and D14S1069 on chromosome 14q22-23. A maximum two point lod score of 5.19 at theta = 0 was obtained with the markersD14S274. The positional and functional candidate genes SIX1, SIX4, SIX6, OTX2, and ARHJ were excluded as the cause of cataract in these families.

CONCLUSION

An as yet unidentified gene associated with posterior polar cataract maps to the long arm of chromosome 14q22-23.

In Vivo Muscle Stiffening Under Bone Compression Promotes Deep Pressure Sores

Pressure sores (PS) in deep muscles are potentially fatal and are considered one of the most costly complications in spinal cord injury patients. We hypothesize that continuous compression of the longissimus and gluteus muscles by the sacral and ischial bones during wheelchair sitting increases muscle stiffness around the bone-muscle interface over time, thereby causing muscles to bear intensified stresses in relentlessly widening regions, in a positive-feedback injury spiral. In this study, we measured long-term shear moduli of muscle tissue in vivo in rats after applying compression (35 KPa or 70 KPa for 1∕4–2 h, N=32), and evaluated tissue viability in matched groups (using phosphotungstic acid hematoxylin histology, N=10). We found significant (1.8-fold to 3.3-fold, p<0.05) stiffening of muscle tissue in vivo in muscles subjected to 35 KPa for 30 min or over, and in muscles subjected to 70 KPa for 15 min or over. By incorporating this effect into a finite element (FE) model of the buttocks of a wheelchair user we identified a mechanical stress wave which spreads from the bone-muscle interface outward through longissimus muscle tissue. After 4 h of FE simulated motionlessness, 50%–60% of the cross section of the longissimus was exposed to compressive stresses of 35 KPa or over (shown to induce cell death in rat muscle within 15 min). During these 4 h, the mean compressive stress across the transverse cross section of the longissimus increased by 30%–40%. The identification of the stiffening-stress-cell-death injury spiral developing during the initial 30 min of motionless sitting provides new mechanistic insight into deep PS formation and calls for reevaluation of the 1 h repositioning cycle recommended by the U.S. Department of Health.
