Normal mean values of FR and LR range from 22.7 cm to 37 cm and 16.3 cm to 22.5 cm, respectively. Height significantly correlates with both FR and LR.

Background: Assessment and management of abnormal lumbar spine mobility are essential in the clinical setting. There are limited studies carried out to obtain lumbar range of motion values in children of the Indian population and to explore the anthropometric measurements on it. Purpose: The purpose was to find any association of anthropometric measurements, hamstring muscle length with lumbar range of motion in school age children from South India. Methodology: Active flexion, extension, and right-and left-side bending, and rotation of the lumbar spine were measured using modified Schober's test for 294 normally developing school going children 6-12 years (147 girls, 147 boys) from Mangalore, Karnataka, India. Means were determined for each motion by age and sex. Further, the correlation between spinal mobility and individual factors such as body mass index and hamstring flexibility was explored. Results: Females were identified as have a significantly higher forward flexion, lateral flexion, and rotation range of motion than males. Age, anthropometric parameters, and hamstring length were significant correlates of lumbar spinal mobility. Conclusion: This study provides the reference values for lumbar spinal flexibility in healthful school going children (6-12 years) from India. Females were found to have a considerably higher forward flexion, lateral flexion, and rotation range of motion than males. Age, anthropometric parameters, and hamstring length were significant correlates of lumbar spinal flexibility.How to cite this article: Varangaonkar VC, Ganesan S, Kumar KV.
