Conceptual design of a tracking system for musculoskeletal rehabilitation processes

The physical rehabilitation process seeks to restore features in muscles that have been lost due to injury, illness, or surgery. Having a measure to quantify the patient's progress would mean improvements in the rehabilitation process. These effects would become more noticeable when therapies are performed unaccompanied by a health professional. In this case, there is no way to know if the exercises are being well executed. Also, it is not possible to determine if the patient is evolving, regressing in the rehabilitation process or even whether the patient is doing the exercises. This work presents the conceptual development, design and functional tests of a system to monitoring rehabilitation processes. As a result, a system is obtained to capture EMG signals related to the rehabilitation process. A circuit with amplification and filtering stages is proposed. It is necessary to improve the acquisition system by using other types of electrodes.
