To determine if ulnar length is superior to arm span when used in developing prediction equations for pulmonary function parameters among children.
Children aged 6–18 years without any significant respiratory illness or spine deformities were asked to perform a complete pulmonary function test. arm span and ulnar lenght were also taken and correlated with standing height.
Both armspan and ulnar length have a strong correlation with height. however, armspan has a stronger positive correlation (r2=0.98762) compared to ulnar lenght (r2=0.94238).
Armspan is superior to ulnar length in developing prediction equations for pulmonary function in children and may be used as a surrogate for height.ulnar length is of comparable accuracy in developing prediction equations for pulmonary function in children and may be used with a certain degree of accuracy in predicting pulmonary functions when measurement of armspan is not feasible.
This method can be used in predicting pulmonary function in debilitated children, in children with spinal deformities ,contractures and the like. this method can help in monitoring these patients’ pulmonary progress or deterioration during treatment.
