Title: Direct feedback application for training with Osteoarthritis affected to the lower extremities
Authors: Carlberg, Emelie
Abstract: This master’s thesis covers the development of an application for patients and healthcare providers training to alleviate Osteoarthritis symptoms. The method used in this application to judge if the training is performed in a safe and correct manner is by using angles. These angles are measured using the smartphone accelerometers, magnetometer and gyroscope. These signals are used to provide direct feedback to the user, using Euler angles and a complementary filter. The results indicate that the smartphone application can measure the angles of interest with good precision. There is still need for further development due to the problems of gimbal locking using Euler angles. Conclusions from the work is that there is great potential using the application both from a patient perspective and as a long term method for healthcare providers to follow up without physical visits.
