Normative reference values for functional, lateral, and oblique direction reach tests in Saudi children aged six to 15 years old and psychometric properties of the oblique direction reach test.

To establish normative values for functional, lateral, and Oblique Direction Reach Tests (ODRT) and to assess the validity and reliability of the ODRT in Saudi children of age 6-15 years. Three hundred Saudi children of age 6-15 years children were recruited by using snowball sampling. Children were measured for distance reached in forward, lateral, and oblique direction on a graph paper, which was mounted on a wall/cardboard. The Mean ± SD for forward, lateral and oblique direction reach was 25.63 ± 6.95, 18.91 ± 5.66, 22.08 ± 5.98 cm respectively. The Intraclass Correlation Coefficient values of intra and inter-rater reliability of ODRT shown to be 0.94 and 0.91, respectively. Concurrent validity of ODRT with forward and lateral reach test is 0.87 and 0.84, respectively. : We established the normal values for functional, lateral, and ODRT in 6-15 years of Saudi children. We found that ODRT is a valid and reliable for measuring limits of stability in oblique direction.
