They are compared with a method requiring only a 3D gyroscope and assessed with a reference system. The good reported accuracies make this system suitable for clinical evaluation.Quaternion-based fusion of gyroscopes and accelerometers to improve 3D angle measurementtext::journal::journal article::research article
