Background and Aim: As many experts believe that the importance of accuracy of measuring devices in the physical education results, especially in the measurement of the arc of the spine, the aim of the present study is to determine reliability and validity of ultrasonic wave arc detector device in measurement of lumbar lordosis angle compared with the golden standard X-Ray method. Materials and Methods: After making the device, lumbar lordosis angle of 31 participants were measured by three examiners three times in at least two hours intervals with the device for determining of its reliability lumbar lordosis angle of15 participants were measured through radiographic and proposed techniques in order to measure the device validity. The participants were selected from available individuals, and volunteers' people of Birjand city. Results: Reliability of the first, second and third examiners were 0.97, 0.98 and 0.98 respectively and reliability between examiners periods were 0.96, 0.97 and 0.95 respectively, the significant correlation (p≤0.05) between the proposed method and the reference one was r=0.95. Conclusion: the high reliability and validity of the proposed method can be due to the least interference of examiner in measurement process and use of high-precision engineering and computational methods. So this method can be used for measurement of lumbar lordosis angle along with other non-invasive methods can be used as stable and reliable method.
