ABSTRACT
Different techniques have been used in the recent past to capture and analyze locomotion, in order to characterize and improve body postures, and detect early stages of pathologies that cause mobility difficulties (Z. Yuting et al., 2011). Probably the most popular, the technology based on Vision makes use of cameras to capture the spatial location of special identifiers that are attached to the lower limbs. There exist other approaches, such as recording kinematic variables by using accelerometers and gyroscopes fastened to body segments. Electromyography is also used to monitor the muscle activity in the lower limbs. These systems, when combined may give very important information to the professionals. However the present solutions have a major drawback: These systems are expensive and complex, difficult to apply by healthcare staff, difficult to use and uncomfortable for the patient.
