An index for quantifying deviations from normal gait.

A method is derived to calculate the amount by which a subject's gait deviates from an average normal profile, and to represent this deviation as a single number. The method uses principal component analysis to derive a set of 16 independent variables from 16 selected gait variables. The sum of the square of these 16 independent variables is interpreted as the deviation of the subject's gait from normal. Statistical tests of the method's validity and an initial demonstration of its clinical utility are included. It is found that using this index, increasing clinical involvement corresponds to increasing index score.

Reliability and validity of the Gillette Functional Assessment Questionnaire as an outcome measure in children with walking disabilities.

A 10-level, parent-report walking scale encompassing a range of walking abilities from nonambulatory to ambulatory in all community settings and terrains was developed at Gillette Children's Specialty Healthcare (GCSH) as part of the Gillette Functional Assessment Questionnaire (FAQ). The reliability and validity of the walking-scale portion of the FAQ were tested on a group of individuals seen in the Motion Analysis Laboratory at GCSH between May 1996 and January 1997. A complete data set on 41 individuals with neuromuscular conditions represented the community ambulation levels (6-10) of the walking scale. Good test-retest reliability among parents and good interrater reliability between parents and community caregivers was demonstrated. Content and concurrent validity were also high, as assessed by correlation to standardized functional outcome measures, energy expenditure, and gait-analysis information. A reliable and valid scale specific to the task of walking such as the FAQ can assist clinicians in documenting functional change in children with chronic neuromuscular conditions.
