AbstractSmartphones have become a very important thing in the digitaly year. Their function not only for communication tool but also as a lot of another function as their value add such as a healthcare tool to helping professional healthcare to measure range of motion of human body movement. G-Pro is one of digitaly goniometric application for helping healthcare professional to measure the range of motion of upper and lower extremity. Occupational therapy students in University of Indonesia using this technology to learning how to measure the range of motion of human body, but actually there is no research about validity and reliability of this tool in Indonesia. The purpose of this research is to analyze the reliability and validity of a G-Pro app as compared with traditional goniometry. 21 subjects of occupational therapy students in University of Indonesia, in 2018 had 4 measurements of their degree of shoulder extension for a randomly chosen shoulder position: 2 by universal goniometry (UG) and 2 by the Goniometer-Pro (G-Pro) application. A different evaluator made each measurement. The difference between mean intra-group values was 3,148Âº (Â±2,669Âº) and 2,476Âº (Â±2,638Âº) for G-Pro. The difference between the mean intra-group values was 5.45Âº. Inter-observer consistency for UG was 0,990 and 0,993 for G- Pro; As regards validity, the values obtained were 0,976 for UG and 0,992 for G-Pro. The Goniometer-Pro app seems to be a reliable and accurate tool for determining the values of shoulder extension. The values obtained are slightly more accurate than those of traditional goniometry. This study intend to promote the use of apps of systemic form in the health system, as a component integrated into the management of the health. This work not only compares the reliability of two methods of measurement, compare the reliability or validity with a gold standard, as it is the radiological measurement.
