Compliant shoulder rehabilitation exoskeleton

Abstract

The invention discloses a compliant shoulder rehabilitation exoskeleton. The compliant shoulder rehabilitation exoskeleton can also be used for independent acromioclavicular and scapular rehabilitation on the basis of shoulder rehabilitation. The compliant shoulder rehabilitation exoskeleton comprises a base, a shoulder self-alignment mechanism, a shoulder rehabilitation mechanism and a connectingpiece; the shoulder rehabilitation mechanism can achieve equivalent training of shoulder abduction/adduction, forward extension/backward swing and inward rotation/outward rotation. The self-alignmentmechanism guarantees that the rotating center of the shoulder rehabilitation mechanism is aligned with the rotating center of the humerus of the human body in the rehabilitation process, so that discomfort or secondary injury caused by extra force and torque is avoided; meanwhile, the self-alignment mechanism can be switched into a shoulder girdle rehabilitation mechanism to drive a shoulder girdle to do forward stretching/backward and upward lifting/downward pressing exercises, and therefore, exercise forms are increased, and the rehabilitation effect is improved.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a compliant shoulder rehabilitation exoskeleton. Background technique [0002] With the intensification of my country's population aging, the proportion of the elderly in the population is getting higher and higher. By the end of 2018, my country's elderly population over 60 years old was 249 million, accounting for 17.9% of the total population. By 2025, my country's population over the age of 60 will reach 300 million, becoming a super-aged country. Because after the end of the 1970s, the family planning work was strengthened, and the aging process of my country's population will reach its peak in 2040. The prolongation of human life expectancy will inevitably lead to physiological decline and reduced flexibility of limbs, and with the frequent occurrence of cerebrovascular diseases and nervous system diseases among the elderly, symptoms of hemiplegia may appear, affecting the n...

AI Technical Summary

Problems solved by technology

Relying on the traditional method of exoskeleton to drive the humerus can exercise the effect of shoulder girdle to a certain extent, but because the range of motion of the humerus set by the exoskeleton is limited, the effect of exercising the shoulder girdle is often not sufficient

Because the rotator cuff of patients with hemiplegia often loses the restraint function of the humerus, excessive lifting and abduction of the humerus may cause acromion impingement or rotator cuff tearing, resulting in subacromial pain syndrome, so the general rehabilitation of exoskeletons requires Inability to move the shoulder girdle sufficiently to elevate and abduct the humerus within safe limits
