Children with visual impairments may have altered joint movement: an observational case-control study

Abstract

To assess the articular range of motion in children with congenital visual impairment. Were evaluated 75 children between five and twelve years old, 49 with normal visual acuity and 26 visually impaired. Two evaluators performed the measure of active and passive range of motion by goniometry of shoulder and hip in all axes of motion. All examiners made a test of correlation between data obtained, to determine the inter-rater reliability, using the intraclass correlation coefficient (ICC). In individuals with visual impairments was statistically significant difference, with higher range of motion in individuals with visual impairments to medial and lateral rotation of shoulder and hip lateral rotation. Were found: high correlation in the inter-rater reliability (ICC>0.70) for 9 (22.5%) groups of articular range of motion, moderate correlation (0.7>ICC>0.5) for 25 (62.5%) groups and low correlation to 6 (15%) groups ranges of motion. Sampled children with congenital visual impairment showed greater joint mobility for rotational range of motion of the shoulder and hip than children with normal visual acuity, although they have also shown lower values for articular range of motion in abduction and extension in shoulders.
