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.

Supported standing and stepping device use in young children with cerebral palsy, gross motor function classification system III, IV and V: a descriptive study

This study described and compared use of supported-standing and stepping devices by young children with cerebral palsy, Gross-Motor Function Classification System (GMFCS) levels III-V following power mobility introduction. Data was collected at two time-points, 5-6 months apart, for 42 participants, aged 18-80 months, using the Home Use of Technology for CHildren (HUTCH). Supported-standing and stepping device choice, and time in each device remained stable over 6 months. Associations between device use and three functional classifications were examined. Children with more impaired motor, postural and manual abilities were more likely to use a supine stander rather than a prone/upright stander or no stander. Children at GMFCS V tended to use hands-free stepping devices, while support-arms stepping devices were more common for children at GMFCS IV. Only children at GMFCS III used convertible stepping devices. Using power mobility, standers and supported-stepping devices was feasible and 19/34 classified at GMFCS IV/V used all three devices over 6 months. A key finding was that introduction of power mobility did not reduce use of supported-stepping devices at any GMFCS level. Use of multiple upright positioning and mobility devices may assist children with limited mobility to be actively engaged and participate in daily life.

Feasibility Study of a Therapeutic Mobility Summer Camp for Children with Severe Cerebral Palsy: Power Fun

Aim: Powered mobility has positive effects on development of children with limited independent locomotion, but many are deprived of this opportunity due to their limitations. This study aimed to evaluate the feasibility of Power Fun, a therapeutic summer camp, for students with severe cerebral palsy (CP).Methods: Five students with CP, ages 11-15, received personally adapted powered wheelchairs and participated daily in the camp. The camp ran five days a week during three weeks and included two mobility sessions daily. Assessments were conducted three weeks prior to the camp (T1), at baseline (T2), post-intervention (T3) and six weeks follow-up (T4). Measures used were Power Mobility Program (PMP), Assessment of Learning Power mobility use (ALP), Wheelchair Outcome Measure for Young People (WhOM-YP), Goal Attainment Scaling (GAS) and Dimensions of Mastery Questionnaire (DMQ).Results: All participants finished the camp. Outcome measures showed no change between T1-T2 but improved significantly (p<.05) after the intervention (T2-T3), and gains were maintained at T4 (Wilcoxon signed-rank test). Goals improved to slightly above the expected outcome (GAS average 0.11).Conclusions: Power Fun shows good feasibility and significant improvement in mobility skills and goals of children with severe CP. Further studies are warranted.

Powerful or Powerless? Children's, Parents', and Occupational Therapists' Perceptions of Powered Mobility

Aim: In Québec, Canada, the prevalence of children using powered mobility (PM) is not reflective of evidence supporting its use and for achieving developmental milestones. The aim of this study was to explore the perceptions of four key stakeholder groups in a metropolitan area regarding daily use, barriers, facilitators, and clinical practice associated with use of PM. Methods: Using convenience sampling, semi-structured qualitative interviews were conducted with children (n = 6), parents (n = 2), rehabilitation center occupational therapists (OTs; n = 4), and special needs school-based OTs (n = 6). Drawings were used as a supplemental data collection strategy with children. Interviews were audio recorded and transcribed verbatim to conduct thematic analysis. Results: Three overarching themes were identified: (1) "A sense of liberty, except…", highlighting environmental obstacles reducing social participation; (2) "A necessity, for better or for worse," covering benefits and drawbacks of PM; and (3) "First choice versus last resort," raising clinical differences related to provision, assessment, and training. Conclusions: Stakeholders' perceptions illustrated benefits of PM, yet use is contingent on the physical, institutional, and societal environments, leading stakeholders to feel both powerful and powerless as users, parents, or clinicians.

The meaning ascribed to wheeled mobility devices by individuals who use wheelchairs and scooters: a metasynthesis

PURPOSE

To synthesize qualitative study findings on the meaning ascribed to wheelchairs and wheeled mobility devices (WMD) by WMD users.

METHOD

Bibliographic databases were systematically searched up to January 2015 to identify relevant papers. Reviewers selected studies, assessed methodological quality and thematically synthesized findings using a metasynthesis process described by Thomas and Harden (2008).

RESULTS

Twenty articles were included. Four descriptive themes emerged: physical environment interaction; sociocultural experiences; participation in activities and occupations; and WMD-self relationship. WMD use was found to be a complex experience that can fluctuate through interaction with aspects of the environment and opportunities for participation. The analytic theme, dynamic duality of WMD experience, addressed the simultaneous enabling and disabling aspects of WMD use.

CONCLUSIONS

Metasyntheses enable researchers to gain a deeper understanding of issues by examining findings across studies. Findings of this study provide a framework for understanding the complexity of WMD use. The framework has practical applications for clinicians and users of WMD in understanding the experience of WMD to be neither singular nor static. Implications for Rehabilitation The meaning of wheeled mobility device (WMD) use is dynamically influenced by the environment and opportunities afforded for occupational and social participation. A duality of experiences can emerge for WMD users, where wheeled mobility use can be at the same time positive and negative, based on the interaction with the environment. Clinicians need to determine the meaning that each individual user ascribes to the WMD, and to consider how that meaning may change over time. By understanding the meaning ascribed to WMD use by individuals, clinicians can be better prepared to work with the WMD users to address negative reinforcers of the experience in physical and sociocultural environments as well as highlighting the positive experiences.

Rare diseases: matching wheelchair users with rare metabolic, neuromuscular or neurological disorders to electric powered indoor/outdoor wheelchairs (EPIOCs)

PURPOSE

To describe the clinical features of electric powered indoor/outdoor wheelchair (EPIOC) users with rare diseases (RD) impacting on EPIOC provision and seating.

METHOD

Retrospective review by a consultant in rehabilitation medicine of electronic and case note records of EPIOC recipients with RDs attending a specialist wheelchair service between June 2007 and September 2008. Data were systematically extracted, entered into a database and analysed under three themes; demographic, diagnostic/clinical (including comorbidity and associated clinical features (ACFs) of the illness/disability) and wheelchair factors.

RESULTS

Fifty-four (27 male) EPIOC users, mean age 37.3 (SD 18.6, range 11-70) with RDs were identified and reviewed a mean of 64 (range 0-131) months after receiving their wheelchair. Diagnoses included 27 types of RDs including Friedreich's ataxia, motor neurone disease, osteogenesis imperfecta, arthrogryposis, cerebellar syndromes and others. Nineteen users had between them 36 comorbidities and 30 users had 44 ACFs likely to influence the prescription. Tilt-in-space was provided to 34 (63%) users and specialised seating to 17 (31%). Four users had between them complex control or interfacing issues.

CONCLUSIONS

The complex and diverse clinical problems of those with RDs present unique challenges to the multiprofessional wheelchair team to maintain successful independent mobility and community living. Implications for Rehabilitation Powered mobility is a major therapeutic tool for those with rare diseases enhancing independence, participation, reducing pain and other clinical features. The challenge for rehabilitation professionals is reconciling the physical disabilities with the individual's need for function and participation whilst allowing for disease progression and/or growth. Powered wheelchair users with rare diseases with a (kypho) scoliosis require a wheelchair system that balances spine stability and movement to maximise residual upper limb and trunk function. The role of specialised seating needs careful consideration in supporting joint derangements and preventing complications such as pressure sores.

Recipients of electric-powered indoor/outdoor wheelchairs provided by a national health service: a cross-sectional study

OBJECTIVE

To describe the characteristics across all ages of powered wheelchair users and the assistive technology prescribed by a regional specialist wheelchair service.

DESIGN

Cross-sectional study.

SETTING

Regional wheelchair service.

PARTICIPANTS

Electric-powered indoor/outdoor wheelchair (EPIOC) users (N=544) with 262 boys and men (mean age ± SD, 41.7±20.7y; range, 8-82y) and 282 girls and women (mean age ± SD, 47.2±19.7y; range, 7-92y).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Demographic, clinical/diagnostic details of EPIOC recipients, including pain, (kypho)scoliosis, and ventilators. Technical features, including specialized (adaptive) seating, tilt in space, and modified control systems. Factors were related to age groups: 1 (0-15y), 2 (16-24y), 3 (25-54y), 4 (55-74y), and 5 (≥75y).

RESULTS

Neurologic/neuromuscular conditions predominated (81%) with cerebral palsy (18.9%) and multiple sclerosis (16.4%). Conditions presenting at birth or during childhood constituted 39%. Of the participants, 99 had problematic pain, 83 had (kypho)scoliosis, and 11 used ventilators. Specialized (adaptive) seating was provided to 169 users (31%); most had cerebral palsy or muscular dystrophy. Tilt in space was used by 258 (53%) participants. Younger people were more likely to receive tilt in space than older ones. Only 92 had specialized (adaptive) seating and tilt in space (mean age ± SD, 29±17.8y; range, 8-72y). Of the participants, 52 used modified control systems.

CONCLUSIONS

The diversity of EPIOC users across age and diagnostic groups is shown. Their complex interrelations with these technical features of EPIOC prescriptions are explored. Younger users were more complex because of age-related changes. This study provides outcomes of the EPIOC prescription for this heterogeneous group of very severely disabled people.
