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.

Aims: 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. Methods: 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. Results: 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. Conclusion: 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.
