Goniometer based to computer

A goniometer based to computer has been developed focused on the measurements of angles of the arms. Universal goniometers are commonly used during physical assessments of patients under physiotherapeutical treatments, but the measurement accuracy is influenced by its own quality and also by the differences among articulations being assessed. In order to ease the specialist´s work, a goniometer based to computer fixed to the patient has been designed to give the angle of the arms, allowing a faster evaluation of the patient´s progress. The angle is measured using an optical encoder and its value is properly interpreted by the PC and presented on the monitor. The use of a computer also allows an adequate recording of the data, which may be later analysed with ease, precision and readability as compared to the conventional method.
