Insights
This review maps wheelchair outcome measures for children, finding most focus on manual wheelchair propulsion. Key areas like responsiveness and intra-rater reliability need more research for better clinical practice.
Area of Science:
- Rehabilitation research
- Pediatric assistive technology
- Measurement science
Background:
- Outcome measurement instruments are crucial for evaluating wheelchair interventions in children.
- A comprehensive understanding of existing instruments is needed to guide research and clinical practice.
- Previous reviews have not systematically mapped the landscape of wheelchair outcome measures for pediatric users.
Purpose of the Study:
- To conduct a scoping review to explore and map wheelchair outcome measurement instruments used for children.
- To identify the characteristics and psychometric properties of these instruments.
- To highlight gaps in the current literature regarding pediatric wheelchair outcome measurement.
Main Methods:
- A scoping review following the Joanna Briggs Institute (JBI) methodology.
- Inclusion of children (≤18 years) who use manual or motorized wheelchairs.
- Systematic search of nine electronic databases and grey literature, with descriptive analysis of extracted data.
Main Results:
- 33 instruments across 27 studies were identified, predominantly for manual wheelchair users.
- Performance-based outcomes and construct validity/test-retest reliability were most frequently assessed.
- Responsiveness and intra-rater reliability were least reported psychometric properties.
Conclusions:
- Current wheelchair outcome measures for children primarily target manual wheelchair users and propulsion performance.
- There is a significant underreporting of responsiveness and intra-rater reliability, indicating a need for future research.
- Standardized methodologies and detailed reporting are essential for advancing pediatric wheelchair research and clinical application.
Purpose:
This scoping review aimed to explore and map wheelchair outcome measurement instruments for children in the literature.
Materials And Methods:
A scoping review was conducted following the Joanna Briggs Institute (JBI) methodology. The review focused on children (≤18 years) manual or motorised wheelchair users, and included primary sources of literature on wheelchair outcome measurement instruments. A search was conducted in nine electronic databases, including grey literature. Data on general characteristics, psychometric properties (validity, reliability, responsiveness) were extracted and analysed descriptively.
Results:
A total of 27 studies and 33 instruments were included, mostly focused on manual wheelchair users (n=23). Performance-based outcomes instruments were the most common (n=15). Construct validity (n=19) and test-retest (n=19) were the most assessed psychometric property. Responsiveness (n=3) and intra-rater (n=3) were the least reported. The most frequently conducted statistical analyses were: minimal detectable difference (MDD) (n=12), standard error of measurement (SEM) (n = 12), intraclass correlation coefficient (ICC) (n=16) and Pearson correlation (n=9). The most common construct was propulsion perfomance in a manual wheelchair (n=6).
Conclusion:
Wheelchair outcome measurement instruments for children mainly assess manual wheelchairs, emphasising propulsion perfomance as the primary outcome. Responsiveness and intra-rater are underreported, highlighting a gap for future research. Standardised methodologies and detailed reporting, including sample size specifications, are essential for advancing research and clinical practice.
