In the field of medicine, measuring the range of motion (ROM) is an important aspect in the diagnosis of medical conditions. The common tool for this task is the universal goniometer, but its use requires skill and is prone to errors from the user due to poor placement. In recent years, several proposals have emerged, such as photogrammetry and human pose tracking, to ease the measurement and automation of this task. This document proposes an app GoDante that seeks to implement both photogrammetry and computer vision to automate the measuring of ROM in patients. Twenty-four subjects were enrolled in the study to measure 24 angles in different joints. Although clinical trials are still pending, preliminary tests were conducted by two physical therapists. Student’s t-tests were performed to evaluate the performance of the GoDante measurement versus the use of a conventional goniometer, revealing differences mainly due to the variability in measurement techniques between the physical therapists. The results of these tests showed that the average ROM values fell within the expected range, with minimal physical contact required during use. These findings demonstrate the feasibility and comfort of the device for ROM measurement, along with its user-friendly interface and ease of use.
