Description
Technical field
The present invention relates to a kind of medical diagnosis device, relate in particular to a kind of test platform that can carry out turning in the ankle joint in the normal walking process of safe simulation state.
Background technology
Ankle joint instability is the damage of clinical common motion relevance, is the sprained ankle common sympton, is common in that the sprained ankle acute stage is not correctly diagnosed and the timely patient for the treatment of, only in the U.S., have every year more than 1,200,000 person-time owing to this damage is gone to a doctor.If ankle joint instability can not get in time correct processing, ligament around the ankle joint can not get repairing and relaxes, muscular strength around the whole ankle joint descends, and the proprioreceptor damage is easy to cause occur repeatedly spraining, have a strong impact on motor function in addition orthobiosis quality.Document shows, approximately 6% ankle joint instability patient finally can not return to original occupation, and still can there be Career Obstacle in the patient of 13%-15% in wound in rear 9 months to 6 years.
In view of its common property with to health larger hazardness being arranged, how effectively to treat ankle joint instability and be all the time the focus in the medicine in field of sports medicine, also is the difficult point of research.
The pathological change of ankle joint instability comprises that laceration of ligament, balance defective, somesthetic sensibility disappearance, diseased lateral reflection Stable Defects, ankle motion are learned and the change of dynamic (dynamical) change and range of motion.Operation (comprising that ligament tightens stitching, ligament reconstruction and ankle arthroscopy etc.) can well be processed clear and definite structural damage (such as laceration of ligament, synovitis etc.), and obtained good effect, but operation can only be processed the damage of structural damage such as ligament, cartilage, synovial membrane etc., can not process the functional unusual of a series of unstructuredness, and these may affect patient's motor function unusually, make the patient can not recover the function of ankle joint fully.
Therefore, how feeding back timely the dislocation of ankle joint degree is very important for treatment and the rehabilitation of ankle joint instability, the disclosed ankle high-frequency ultrasonic examination sac tape of for example disclosed a kind of ankle joint laxity determinator of patent CN201863905U, and patent CN202051727U.But, existing technology can only test patient various dysfunctions in static or normal walking process, but can not detect the patient at the interior functional defect that climbs in the journey.
Therefore those skilled in the art is devoted to develop and a kind ofly can simulates safely the test platform that the experimenter turns over state in when normally walking, and can be used for the purposes such as Clinical detection, rehabilitation and scientific research of ankle joint instability.
