Acupoint-stimulated knee orthosis

Abstract

The invention provides an acupoint stimulation type knee orthosis, which relates to the technical field of rehabilitation engineering. The knee orthosis body is used for fixing, correcting and supporting the knee joint, and the knee joint orthosis body is in close contact with the dense tissue of the knee joint; a plurality of acupoint stimulation electrode sheets are arranged at the acupoint contact point between the knee orthosis body and the knee joint, and the acupoint stimulation electrode sheets are of a multi-layer structure, comprising an adsorption layer, a conductive layer and a release membrane layer, wherein the conductive layer is provided with an outer interface; a therapeutic apparatus is electrically connected to the external interface through a wire for providing a low frequency pulse current to stimulate acupoints at the knee joint. The acupoint stimulation type knee orthosis provided by the invention utilizes the electric stimulation of the combined acupoints to enhance the therapeutic effect on knee osteoarthritis, can also exert the effect in the exercise, and can shorten the wearing time of the orthosis and increase the analgesic effect.

Description

technical field [0001] The invention relates to the technical field of rehabilitation engineering, in particular to an acupoint stimulating knee orthosis. Background technique [0002] According to the World Health Organization survey, the incidence rate of osteoarthritis is about 50% for people over 50 years old, and 80% for people over 55 years old. According to statistics from the Committee on Aging: At the end of 2013, my country's elderly population (people over 60 years old) was 202 million. If calculated according to the above incidence rate, about 160 million people in my country suffer from osteoarthritis. The knee joint is the largest load-bearing joint. During daily walking, the contact pressure between the tibia and femur is 8 to 9 times the body weight. Osteoarthritis is the most prone to occur, causing knee pain, quadriceps muscle weakness and proprioception Decreased sensitivity and increased postural sway affect quality of daily life. Among different types...

AI Technical Summary

Problems solved by technology

The operation is expensive, the postoperative recovery period is long, and there are many postoperative complications, and even a second operation is required. The elderly have serious bone and joint degeneration, and the condition is prone to recurrence, so it is not suitable for surgical treatment

So far there is no fundamental drug to cure osteoarthritis and it is expensive

In terms of auxiliary tools, there are physical therapy instruments such as knee joint therapy instruments in clinical practice, but they can only be used before or after exercise, and the effect is still relatively limited.

However, the effect of simply using the valgus knee joint is slow, and the pain relief effect has not been significantly improved in the short term.
