Biofeedback and Modern Imaging Methods for Rehabilitation

abstract

English

Nowadays, assessment of functional changes of human musculoskeletal system is based primarily on subjective evaluation of physiotherapists, orthopaedist and rehabilitation specialists. Expert community lacks appropriate objective methods for quantification of functional changes such as muscular imbalance or uncoordinated posture of a body segment. Specialists also lack a possibility to objectively assess effects of targeted rehabilitation. Since it is impossible to objectively evaluate positive changes of conservative therapy, arthroscopic surgery is oftentimes performed, irreversibly disrupting surrounding tissues. Besides the direct invasive intervention in the integrity of the body segment, there are other disadvantages of surgical intervention: the surgery itself is expensive and time demanding, and convalescence of patients is long. Thus our goal is creation of new possibilities of non-invasive diagnostics of ankle-joint and in-depth assessment of functional posture of extremities in static posture, potentially in dynamic posture too. Basic requirement is establishment of external referential points on the lower extremity. Mutual spatial arrangement of these points will provide predictive value about the position of internal structure. Such referential points will be recorded by modern imaging sensors. One of the possible suitable sensors is Kinect One from Microsoft. Contrary to common colour cameras, Kinect One allows in-depth 3D sensing of the scene which enables high quality reconstruction of the scanned part of the patient’s body, especially more faithful kinematic bone model. Compared to other typically used optical proximity sensors, Kinect One is cheaper while providing sufficient parameters important for the given application (space as well as length resolution, framerate, latency, etc.).
