The effect of walking with an assistive device and using a wheelchair on school performance in students with myelomeningocele

RESNA position on the application of power mobility devices for pediatric users

This paper serves as an update to the previous RESNA Position on the Application of Power Wheelchairs for Pediatric Users with more current and additional scientific literature. This document contains typical clinical applications and best evidence from the literature supporting the application of power mobility (PM) for young children and to assist practitioners in decision-making and justification. It is RESNA' s position that age, limited vision or cognition, behavioral issues, and the ability to walk or propel a manual wheelchair short distances should not, in and of themselves, be used as discriminatory factors against providing PM for children. RESNA recommends early utilization of PM for children with mobility limitations as medically necessary, to promote integration and psycho-social development, reduce passive dependency, and to enhance participation, function, and independence.

Orthopedic management of myelomeningocele with a multidisciplinary approach: a systematic review of the literature

Background

Myelomeningocele (MMC) is the most common and severe form of spina bifida and imposes a significant burden on patients and the healthcare system. Recently, the multidisciplinary management of MMC has become popular. Herein, we aimed to review the orthopedic management, outcomes, and complications of the of patients with MMC eyeing a multidisciplinary approach.

Methods

We searched PubMed and EMBASE to find relevant studies published before August 2020. All studies that included clinical management of MMC patients and published earlier than 2000 were considered for review on the condition that they reported at least one orthopedic intervention and the rate of complications. We excluded review articles, case reports, case series, letters, commentaries, editorials, and conference abstracts. The primary and secondary goals of our review were to report the outcomes and complication rates of multidisciplinary management for MMC patients.

Results

Twenty-six studies included data for the management of 229,791 patients with MMC and were selected. Sixteen studies reported multidisciplinary management in addition to orthopedic management. From those, 11 (42.31%) included urologic management, 13 (50%) neurosurgical management, 11 (42.31%) neurologic management, and 5 (19.23%) gastrointestinal management. All studies included postnatal operations and related management. No randomized clinical trial was found in our search.

Conclusion

Orthopedic approaches play a key role in MMC management by alleviating spinal deformities, particularly scoliosis, and hip, foot, and ankle complications. However, the most appropriate management, whether surgical or non-surgical, may vary for different patients, given disease severity and the age of patients.

Use of single-subject research designs in seating and wheeled mobility research: a scoping review

Background: Evidence-based practice (EBP) in seating and wheeled mobility practice is often hindered by a dearth of published research.Purpose: The purpose of this review was to explore and critically appraise the use of single-subject research designs (SSRDs) in seating and wheeled mobility studies published between January 1995 and May 2018.Study Selection: Primary source, peer-reviewed SSRDs focused on exploring the impact of a seating and wheeled mobility intervention were included in the review.Data Extraction: Relevant data extraction, determination of level of evidence, evaluation of methodological rigor, and assessment of the risk of bias were each independently performed.Data Synthesis: The review yielded 19 studies (2 Level III, 15 Level IV, and 2 Level V). A majority of these studies incorporated a withdrawal-type of SSRD and involved subjects representing patient populations with seating and wheeled mobility needs. Methodological rigor/quality features most commonly absent in the included studies included: blinding/masking, inter-rater or intra-rater reliability, >5 data points in each phase, planned replication (≥3 subjects), procedural fidelity methods, randomization, stability of the data during baseline, statistical analyses and use of subject selection criteria. The limited number of published SSRDs, combined with the lower levels of evidence (Levels III-V) provided by these studies, indicates that the use of SSRDs in seating and wheeled mobility research is in the early stages of development.Conclusions: Increasing the methodological quality and rigor as well as reporting methods in future SSRDs involving seating and wheeled mobility interventions may help to support EBP in this area.Implications for RehabilitationSingle-subject research designs (SSRDs) offer both researchers and clinicians the opportunity to contribute to the existing knowledge base in ways that reflect actual clinical practice.SSRDs provide flexibility in adapting and modifying seating and wheeled mobility-related assistive technology devices to meet the individual needs of specific subjects.SSRDs preserve individual responses to seating and wheeled mobility-related assistive technology devices.SSRDs may help to enhance evidence-based practice (EBP) in seating and wheeled mobility practice by spanning the divide between research and practice.Increasing the methodological quality and rigor as well as reporting methods in future SSRDs may help to support EBP in seating and wheeled mobility practice.

Power-Up: Exploration and Play in a Novel Modified Ride-On Car for Standing

PURPOSE

The purpose of this study was to compare the physical activity and play behaviors of preschoolers without disabilities and 1 preschooler with physical disability.

METHODS

Participants were 42 preschoolers without disabilities and 1 preschooler with physical disability (Child A). Child A used either crutches or a modified ride-on car while in the gymnasium and playground.

RESULTS

In the gymnasium, Child A engaged in less solitary play and more parallel play while using the modified ride-on car compared with crutches. On the playground, Child A engaged in more sitting and less running while using crutches compared with preschoolers without disabilities. On the playground, Child A engaged in more peer interaction and less teacher interaction when using the modified ride-on car compared with crutches.

CONCLUSIONS

For children with disabilities who may use assistive devices, clinicians, families, and teachers are encouraged to embrace a "right device, right time, right place" approach.

Past and current use of walking measures for children with spina bifida: a systematic review

OBJECTIVES

To describe walking measurement in children with spina bifida and to identify patterns in the use of walking measures in this population.

DATA SOURCES

Seven medical databases-Medline, PubMed, Embase, Scopus, Web of Science, CINAHL, and AMED-were searched from the earliest known record until March 11, 2014. Search terms encompassed 3 themes: (1) children; (2) spina bifida; and (3) walking.

STUDY SELECTION

Articles were included if participants were children with spina bifida aged 1 to 17 years and if walking was measured. Articles were excluded if the assessment was restricted to kinematic, kinetic, or electromyographic analysis of walking. A total of 1751 abstracts were screened by 2 authors independently, and 109 articles were included in this review.

DATA EXTRACTION

Data were extracted using standardized forms. Extracted data included study and participant characteristics and details about the walking measures used, including psychometric properties. Two authors evaluated the methodological quality of articles using a previously published framework that considers sampling method, study design, and psychometric properties of the measures used.

DATA SYNTHESIS

Nineteen walking measures were identified. Ordinal-level rating scales (eg, Hoffer Functional Ambulation Scale) were most commonly used (57% of articles), followed by ratio-level, spatiotemporal measures, such as walking speed (18% of articles). Walking was measured for various reasons relevant to multiple health care disciplines. A machine learning analysis was used to identify patterns in the use of walking measures. The learned classifier predicted whether a spatiotemporal measure was used with 77.1% accuracy. A trend to use spatiotemporal measures in older children and those with lumbar and sacral spinal lesions was identified. Most articles were prospective studies that used samples of convenience and unblinded assessors. Few articles evaluated or considered the psychometric properties of the walking measures used.

CONCLUSIONS

Despite a demonstrated need to measure walking in children with spina bifida, few valid, reliable, and responsive measures have been established for this population.

Estimating energy expenditure for different assistive devices in the school setting

PURPOSE

This case report describes a simple means of estimating energy costs for a child with cerebral palsy using different assistive devices within a school setting.

KEY POINTS

A 9-year-old boy, Gross Motor Function Classification Scale level III, was assessed over 8 ambulation trials using a posterior walker and using forearm crutches. Each trial was followed by a fine motor accuracy task. An energy expenditure index (EEI) was calculated for each device. For the posterior walker, EEI was 47% higher overall compared with forearm crutches. Fine motor accuracy and task completion time were similar for both devices.

CONCLUSION

EEI was a straightforward method of estimating the energy costs of different assistive devices. Measurement procedures described in this case were time efficient in the field and provided a reasonable estimation of energy expenditure to help decide objectively which assistive device would best fit the needs of the student.

Better walking performance in older children with cerebral palsy

BACKGROUND

Children with cerebral palsy (CP) often walk with a slower speed and a higher energy cost. Their walking performance and choice of mobility method may vary in different environments. Independent mobility is important for activity and participation.

QUESTIONS/PURPOSES

We described walking performance at different distances and environments in relation to gross motor function, CP subtype, and age.

PATIENTS AND METHODS

We performed a cross-sectional study including all 562 children 3 to 18 years with CP living in southern Sweden during 2008. Data were extracted from a Swedish CP register and healthcare program. The Functional Mobility Scale (FMS) was used for rating mobility at home (5 m), at school (50 m), and in the community (500 m). The FMS scores were analyzed in relation to Gross Motor Function Classification System (GMFCS) level, CP subtype, and age.

RESULTS

In this population, 57% to 63% walked 5 to 500 m without walking aids and 4% to 8% used walking aids. We found a correlation between FMS and GMFCS. The walking performance varied between the subtypes from 96% to 98% in those with spastic unilateral CP to 16% to 24% in children with dyskinetic CP. An increased proportion of children walked independently on all surfaces in each successive age group.

CONCLUSIONS

The overall walking performance increased up to 7 years of age, but the proportion of children walking independently on uneven surfaces was incrementally higher in each age group up to 18 years. The ability to walk on uneven surfaces is important for achieving independent walking in the community.

Use of manual and powered wheelchair in children with cerebral palsy: a cross-sectional study

BACKGROUND

Mobility is important for the cognitive and psychosocial development of children. Almost one third of children with cerebral palsy (CP) are non-ambulant. Wheelchairs can provide independent mobility, allowing them to explore their environment. Independent mobility is vital for activity and participation and reduces the dependence on caregivers. The purpose of this study was to describe the use of manual and powered wheelchair indoors and outdoors in relation to the degree of independent wheelchair mobility or need for assistance in a total population of children with CP.

METHODS

A cross-sectional study was performed including all children aged 3-18 years with CP living in southern Sweden during 2008. Data was extracted from a register and health care programme for children with CP (CPUP). There were a total of 562 children (326 boys, 236 girls) in the register. Information on the child's use of manual and powered wheelchair indoors and outdoors and the performance in self-propelling or need for assistance were analysed related to age, CP subtype and gross motor function.

RESULTS

Wheelchairs for mobility indoors were used by 165 (29%) of the 562 children; 61 used wheelchair for independent mobility (32 using manual only, 12 powered only, 17 both) and 104 were pushed by an adult. For outdoor mobility wheelchairs were used by 228 children (41%); 66 used a wheelchair for independent mobility (18 using manual only, 36 powered only, 12 both) and 162 were pushed. The use of wheelchair increased with age and was most frequent in the spastic bilateral and dyskinetic subtypes. Most powered wheelchairs were operated by children at GMFCS level IV.

CONCLUSION

In this total population of children with CP, aged 3-18 years, 29% used a wheelchair indoors and 41% outdoors. A majority using manual wheelchairs needed adult assistance (86%) while powered wheelchairs provided independent mobility in most cases (86%). To achieve a high level of independent mobility, both manual and powered wheelchairs should be considered at an early age for children with impaired walking ability.

Pediatric physical therapists' perceptions of their training in assistive technology

BACKGROUND AND PURPOSE

Availability of assistive technology (AT) and federal legislation promoting greater use of AT for children with disabilities have increased substantially. The purpose of this study was to determine the perceived adequacy of previous training in AT, specific training needs, preferred methods of training, and the confidence level of pediatric physical therapists in providing AT.

SUBJECTS AND METHODS

Three hundred eighty pediatric physical therapists responded to a survey questionnaire mailed to a random sample of members of the Section on Pediatrics of the American Physical Therapy Association. The survey was used to determine training needs of therapists in the area of AT, their confidence in delivering AT services, preferred methods of training, and challenges in becoming trained.

RESULTS

The therapists reported having less-than-adequate training in AT and a lack of confidence in delivering AT services. They also reported that they would like accessible and affordable training that focuses on funding technology and services, knowledge of specific devices, and assessment and evaluation methods.

DISCUSSION AND CONCLUSION

The findings underscore the need to develop pre-service, in-service, and continuing education training opportunities in AT for providers working with children who have disabilities.

Use of strutter orthoses for an adolescent with myelodysplasia

PURPOSE

To describe the functional gains made through the use of the Strutter Functional Orthosis System (SFOS) in an adolescent with myelodysplasia.

SUMMARY

A 12-year-old boy with lumbar level myelodysplasia was not functional when ambulating with Lofstrand crutches. He required a wheelchair for community mobility because of complaints of fatigue and upper extremity discomfort. He was introduced to the SFOS and became a functional community ambulator, reporting greater walking endurance and decreased pain.

CONCLUSIONS

This report provides some case evidence to suggest that the SFOS can improve functional mobility in a child with myelodysplasia. With the SFOS this child progressed from being nonfunctional when ambulating to being classified as a "community ambulator," resulting in physiological, functional, and psychosocial gains.

RECOMMENDATIONS

We suggest future investigations to explore the reasons for greater walking ability with the SFOS.

Lightweight and ultralight wheelchairs: propulsion and preferences of two young children with spina bifida

PURPOSE

This study compared the influence of two wheelchair styles, an ultralight rigid frame and a lightweight folding frame, on preference and propulsion in young children with spina bifida.

PROCEDURE

Speed, distance, energy expenditure, and perceived exertion of two girls were studied in an A-B-A single subject design. Questionnaires were used after the three phases to obtain parent and child preference.

RESULTS

Visual inspection of the data favored the ultralight wheelchair for all variables, except the first child's speed with classmates and perceived exertion. Parents and children indicated preference for the ultralight wheelchair on all questions but one by Child 1. Using two standard deviation band width (2SDBW) analyses, 12 of 16 comparisons between the phases differed significantly. 2SDBW comparison was not used in the other four phase comparisons because of autocorrelations.

CONCLUSION

This study presents initial evidence supporting the use of ultralight rigid-framed wheelchairs by young children.

Unmet Need for Therapy Services, Assistive Devices, and Related Services: Data From the National Survey of Children With Special Health Care Needs

OBJECTIVE

To estimate the prevalence of unmet needs for therapy services, vision and hearing care or aids, mobility aids, and communication aids and to investigate the association between predisposing, enabling, need, and environmental factors and unmet needs.

METHODS

Using the National Survey of Children with Special Health Care Needs, we generated national prevalence estimates and performed bivariate and logistic analyses, accounting for the complex survey design.

RESULTS

Nationally, the prevalence of unmet needs ranged from 5.8% among children with special health care needs (CSHCN) with a reported need for vision care or glasses to 24.7% among CSHCN with a reported need for communication aids. In logit analyses, CSHCN without insurance coverage were significantly more likely to have a reported unmet need for therapy services (adjusted odds ratio [OR]: 2.08, confidence interval [CI]: 1.39-3.12), vision care or glasses (OR: 3.94, CI: 2.64-5.86), and mobility aids (OR: 5.17, CI: 1.86-14.37). Children in families at or below 100% of the federal poverty level were significantly more likely to have a reported unmet need for vision care or glasses (OR: 4.51, CI: 2.86-7.12) and hearing aids or hearing care (OR: 3.61, CI: 1.70-7.65). For each of the services studied, more-severely limited children were significantly more likely to have an unmet need reported.

CONCLUSION

Our findings demonstrate that a minority of CSHCN have unmet needs for therapy services, assistive devices, and related services. Parents of children with more-severe ability limitations were more likely to report having unmet needs. Our findings highlight the importance of insurance coverage in ensuring access to therapy services, assistive devices, and related services.

Evidence-based practice: methods to evaluate individual patient improvement

The expectations and demands associated with evidence-based practice in medical rehabilitation require the use of research procedures that are practice based and practitioner oriented. Traditional research methods, including randomized clinical trials, are powerful techniques for determining the efficacy of rehabilitation interventions; however, randomized clinical trials have some practical and ethical limitations when applied to many research questions important to the field of medical rehabilitation, and alternative methods are needed to fully examine the effectiveness of treatment techniques for individual patients and to document clinical accountability. This paper examines the use of single-system designs and N of 1 research strategies. The advantages and limitations of single-system methods are described, and examples relevant to the documentation of clinical outcomes in medical rehabilitation are presented.

Single-subject research in rehabilitation: a review of studies using AB, withdrawal, multiple baseline, and alternating treatments designs

OBJECTIVE

To review the "methodologic rules" for using single-subject research designs (SSRDs) and to review the use of SSRDs in rehabilitation research of the past decade.

DATA SOURCES

CINAHL and MEDLINE searches using "single subject" and "single system" as key words for the period 1985-1995 yielded 61 articles related to rehabilitation.

STUDY SELECTION

Studies were selected for review if they described one of four commonly used SSRDs, specifically AB, withdrawal, multiple baseline, or alternating treatments.

DATA EXTRACTION

Studies cited were identified by consensus and either exemplify adherence to the experimental rules of SSRDs or illustrate errors that result in threats to the validity of stated findings.

DATA SYNTHESIS

All four types of SSRDs have been reported in rehabilitation studies, sometimes incorrectly.

CONCLUSIONS

SSRDs, with their client-centered focus, are ideally suited for researching human behavior in the rehabilitation practice environment. Although numerous sources clearly identify the methodologic requirements for single-subject experiments, several studies violate the basic rules, threatening the validity of the results of these studies. Other properly applied SSRDs illustrate the strengths of this approach, which can produce empirical support for rehabilitation interventions.

Physical therapy interventions for patients with movement disorders due to cerebral palsy

The purpose of this paper is to present evidence of the efficacy of physical therapy interventions for patients with cerebral palsy and identify goals for these patients. Studies suggest that neurodevelopmental treatment and Vojta techniques improve postural control. Little evidence supports the efficacy of early intervention, but researchers have not yet studied effects on the family. Strengthening, electrical stimulation, the use of orthoses, and seating show positive effects in studies of small numbers of subjects. For severely involved children, ease of care and comfort are important goals, as well as prevention of deformity, which is important for all children. To the extent possible, therapy should prepare a child for independent adult life. In early intervention through school age, therapy focuses on promoting communication, self-care, and mobility. Independence is a key issue for adolescents transitioning into adulthood. The rehabilitation and health needs of adults with cerebral palsy need to be addressed. Research needs to determine the effects of physical therapy not only on impairment but also on function and disability.

Physical conditioning in children with arthritis: Assessment and guidelines for exercise prescription

OBJECTIVE

To review the literature in the area of physical fitness and conditioning programs for individuals with chronic illnesses, and increase the awareness of the need to include fitness testing and conditioning programs in the therapeutic management of children and adolescents with chronic arthritis.

METHODS

This article provides a review of original research reports, information from principal texts, and review articles related to physical fitness testing and training in children.

RESULTS

Several factors limit the exercise capacity of children with chronic arthritis, and studies report that these children have lower aerobic endurance and muscle performance than their peers. Preliminary studies suggest that fitness testing is safe for most children with arthritis, and physical conditioning programs, which appear to benefit adults with arthritis and children with other chronic illnesses, may also benefit children with arthritis. Easily administered, inexpensive field tests of fitness are available. Guidelines for prescribing physical conditioning programs are provided. The risks and benefits of increased exercise are discussed.

CONCLUSIONS

Assessment of exercise capacity and muscle function and individualized prescription of physical conditioning programs are indicated for children with chronic arthritis, soon after diagnosis.

Spina bifida: the transition into adulthood begins in infancy

Many concerns surround the preparation of a person with spina bifida for a successful transition into adult life and responsibilities. A model of intervention must be based on developmental concerns and timely issues from infancy through all stages of development to young-adult life. This article discusses, within a developmental framework, issues of transition in relation to physical, social, emotional, and educational/vocational needs; it also presents a conceptual framework for the transition into adulthood. Guidelines were developed by incorporating expected outcomes of people with spina bifida and using a philosophical framework that encompasses the achievement of a balance among dependence, independence, and interdependence. This model is based on developmental issues from infancy through all stages of development to young-adult life. Using this framework for care, the rehabilitation nurse can feel confident that the needs of clients with spina bifida and similar chronic conditions are being met.
