title: Spinal mobility in young children. A normative study.
abstract: The purpose of this study was to collect values of back mobility on healthy children between the ages of 5 and 9 years. Normative values of back mobility have not been established for children under 10 years of age. Measurements of anterior and lateral spinal flexion were obtained from 282 children, using a standard flexion measurement procedure. Intraclass correlation estimates of reliability ranged from .77 to .89, indicating acceptable agreement and stability across and within raters. Girls demonstrated greater mobility than boys in all three measurements. Post hoc trend analyses revealed consistent increases in left and right lateral flexion with increasing age. No linear trend existed for anterior flexion. Using these data, we developed normative values of back mobility for each sex and age grouping. These measures of back mobility will provide the clinician with an empirically validated comparison to help identify early restrictions in back mobility in children with juvenile arthritis and other pediatric populations who are at risk for restrictions in back mobility. Early identification may lead to better prevention and more timely and effective treatment programs.
