Lower-limb prosthesis alignment and gait analysis auxiliary system adopting foot pressure sensing technology

Abstract

The invention provides an auxiliary system which is capable of assisting a limb prosthesis orthopedic doctor to assemble lower-limb prosthesis and helping an amputee to improve gait on the basis of a foot pressure signal of the amputee. The auxiliary system comprises a main circuit box, a sole pressure sensor assembly and an interface program, and the interface program is applied to a user interface. According to the auxiliary system, the main circuit box and the sole pressure sensor assembly are used together and are transmitted to the user interface in a wireless mode. The auxiliary system mainly operates on the basis of the principles of computing and displaying standing and swinging times of the amputee during walking as well as a reference pressure center path during walking and standing, and comparing with corresponding standard data, so as to suggest the orthopedic doctor in the adjustment of the lower-limb prosthesis alignment and the gait of the amputee. The auxiliary system disclosed by the invention is helpful for the limb prosthesis orthopedic doctor in the adjustment of the lower-limb prosthesis alignment, the assessment of the gait of the amputee after alignment and in the gait training of the amputee.

Description

technical field [0001] The invention relates to the field of clinical prosthetic lower limb assembly and evaluation equipment, in particular to an auxiliary system that utilizes foot pressure signals of amputee to assist prosthetic orthopedists to assemble artificial lower limbs and help amputee improve gait. Background technique [0002] According to the national census of persons with disabilities, physical disabilities account for about 30% of the total number of persons with disabilities, making them the group with the highest proportion of persons with disabilities. More than 2 million of them require amputation. On the other hand, as diabetes becomes more common, it is estimated that the number of amputations due to "diabetic foot" will increase day by day. Under the premise of continuous improvement of living standards and extensive rehabilitation work, not only the disabled themselves, but also all fields of society and scientific research will have higher and highe...
