Abstract:
Hardware and software development from scratch of a low-cost Electrogoniometer for the kinematic analysis of the range of movement from the different joint angles of the body. It was also made a validation of the system and a real-world medical case study with arthrodesis patients. The hardware used was arduino while for software was python. The first test was aimed to get the first contact with the system and to prove that the model was viable, the second test consisted of the validity of the prototype with elbow healthy samples. Finally, the prototype got involve on a clinical case study. For the validity, the EG signal was compared with the goal standard and validated system Kinovea. The main result was the error obtained which was of ± 2.86º out of a 0º to 140º range of movement. This compared with the acceptance error of ± 11.5º from the last review and validation of the classical goniometry is a satisfactory result.
