Efficacy of Augmented Feedback on Lumbar Postural and Movement Control During Physiotherapy and Home Exercise

An inertial measurement unit (IMU) system is the basis of the augmented feedback (AF) system, where the IMU-system communicates with a laptop using a bluetooth dongle. The corresponding software includes therapeutic games. Movements of the lower back and pelvis by the patient are used to control an avatars movement or the graphical interface in computer exercises. The AF-system provides real-time feedback regarding the patient's performance and helps to rectify incorrect execution of the exercises. The intervention took place at a physiotherapy clinic and in an home environment. In the physiotherapy clinic the patients exercised under the supervision of the physiotherapists. They continued the exercises at home as home exercises.
