Description

A device for improving the range of motion of periarthritis of the shoulder

technical field

The invention relates to the technical field of medical devices, in particular to a device for improving the range of motion of periarthritis of the shoulder.

Background technique

Periarthritis of the shoulder, referred to as periarthritis of the shoulder, is due to a wide range of chronic aseptic inflammatory reactions in the joint capsule of the shoulder joint and the soft tissue around the joint, which causes extensive adhesion of the soft tissue and limits the activities of the shoulder joint.

At present, the treatment for this disease is mainly based on acupuncture, massage, oral administration of traditional Chinese medicine, external application of traditional Chinese medicine, physical therapy, intra-articular injection, nerve block, manual release under anesthesia, open surgery or arthroscopic release. Joint mobilization technique is one of the basic skills in modern Western rehabilitation treatment techniques. It is a very practical and effective manipulation skill used to treat joint dysfunction such as joint pain, limited joint mobility or joint stiffness. When applying joint mobilization technology, the physiological movement and accessory movement of the joint are often selected as the treatment means. The physiological movement of the joint refers to the movement completed by the joint within the physiological range, such as joint flexion, extension, adduction, abduction, rotation, etc., which can be completed actively or passively. The accessory movement of the joint refers to the movement that the joint completes within the range allowed by itself and its surrounding tissues, and is an indispensable movement to maintain the normal activities of the joint.

At present, there are not many rehabilitation devices for frozen shoulder. After consulting the relevant patent documents of frozen shoulder, it is found that the external application prescription for frozen shoulder and the shoulder protector for frozen shoulder are the main ones. Clinically, methods such as local sealing, massage, external application, acupuncture, and surgery are commonly used to treat frozen shoulder, but the disadvantages are that the course of treatment is long, the treatment is not thorough, and the recurrence rate is high.

Chinese patent document: CNCN200710168510.X, application date 2007.11.28, patent name: shoulder joint rehabilitation training device. Disclosed is a wearable shoulder joint rehabilitation training device. The device has the characteristics of exercise flexibility, wearing comfort and training safety. The device is composed of a movement mechanism and a support adjustment mechanism. The support adjustment mechanism is used to adjust the position of the movement mechanism relative to the shoulder joint of the human body, and fix the entire rehabilitation training device at an appropriate position on the back of the human body. The driver of the motion mechanism is 4 pneumatic muscles in a vertical motion state, which can respectively control the two groups of movements of the upper arm around the shoulder joint, flexion and extension, abduction and adduction, and the compound movement of these two groups of movements. With the cooperation of the angular displacement and the tension sensor, the active and passive coordinated movement of the movement mechanism and the upper arm can also be realized.

The above-mentioned document adopts a shoulder joint rehabilitation training device, which utilizes the movement mechanism to drive the upper arm movement by means of two passively moving sliders to overcome the problem of upper limb movement difficulties caused by the misalignment of the movement center of the mechanism and the shoulder joint, ensuring Comfort during rehabilitation and safety during training.
