Insights
The Functional Mobility Scale (FMS) and Gillette Functional Assessment Questionnaire - walking scale (FAQ) accurately measure mobility in pediatric neurorehabilitation patients. These scales are valid tools for assessing functional mobility in this population.
Area of Science:
- Pediatric Rehabilitation
- Neuroscience
- Biomedical Engineering
Background:
- Assessing functional mobility is crucial for children undergoing neurorehabilitation.
- Validated tools are needed to accurately track mobility improvements in pediatric neurorehabilitation settings.
Purpose of the Study:
- To determine the concurrent validity of the Functional Mobility Scale (FMS) and the Gillette Functional Assessment Questionnaire - walking scale (FAQ).
- To evaluate the FMS and FAQ as reliable measures of functional mobility in pediatric inpatient neurorehabilitation.
Main Methods:
- Cross-sectional study of 71 children with neuromotor gait impairments.
- Concurrent validity assessed using Spearman correlations against established mobility measures.
- Data collected by independent physiotherapists within a 7-day period.
Main Results:
- Both FMS and FAQ demonstrated strong correlations with comparator measures (0.58-0.79 for FMS, 0.69-0.73 for FAQ).
- Study hypotheses regarding correlation strength and direction were supported for both scales.
- The FMS captured a broad spectrum of mobility levels.
Conclusions:
- The Functional Mobility Scale (FMS) and Gillette Functional Assessment Questionnaire - walking scale (FAQ) are valid instruments for assessing functional mobility.
- These scales are suitable for use in pediatric inpatient neurorehabilitation settings.
- The findings support the use of FMS and FAQ for evaluating mobility outcomes in children with neuromotor impairments.
Aims:
To investigate the concurrent validity of two mobility performance measures, the Functional Mobility Scale (FMS) and the Gillette Functional Assessment Questionnaire - walking scale (FAQ) in an inpatient pediatric neurorehabilitation setting.
Methods:
Cross-sectional data were collected on 71 children (mean age 12.7 years) with neuromotor gait impairments who participated in an inpatient rehabilitation program to evaluate aspects of concurrent validity of the FMS and FAQ. Physiotherapists independently performed ratings. Comparator instruments included the walking item of the Functional Independence Measure for children, 10-m and 6-minute walking tests, and Gross Motor Function Measure-88 dimension E. All tests were completed within 7 days. Spearman correlation coefficients were calculated to test a priori formulated hypotheses regarding the strength and direction of the measures relationships.
Results:
The children had a broad spectrum of mobility levels, including all levels of FMS and levels 2-10 of FAQ. Spearman correlation coefficients with comparator measures varied between 0.58-0.79 for the FMS and 0.69-0.73 for the FAQ. Hypotheses concerning correlation strengths and directions were met for FMS and FAQ.
Conclusions:
The findings demonstrate that the FMS and FAQ are valid to evaluate functional mobility in pediatric inpatient neurorehabilitation.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
