Description

Shoulder joint rehabilitation training device

Technical Field

The invention relates to the technical field of medical instruments, in particular to a shoulder joint rehabilitation training device.

Background

With the aging population and the increase of physical exercise population, the incidence of rotator cuff injury also increases year by year. Rotator cuff injury is one of the most common shoulder joint diseases, the incidence rate of the rotator cuff injury accounts for 17% -41% of shoulder joint diseases, the symptoms of rotator cuff injury comprise pain, weakness, abnormal sound in joints and limited movement, and the functional disorder caused by rotator cuff injury seriously affects the life quality of patients. It is good for young people and middle aged and elderly people, and is mainly caused by incorrect posture during physical exercise and physical labor. Once the rotator cuff is damaged, not only can the normal shoulder movement of a patient be influenced, but also the ischemia and the oxygen deficiency of local tissues can be induced to cause neuritis, so that the patient can feel stronger physical pain.

The arthroscopic rotator cuff prosthesis has the advantages of small wound, quick recovery and the like, is widely applied clinically and achieves satisfactory treatment effect. The glenohumeral joint adhesion is easily caused by the healing process of the rotator cuff after the rotator cuff is fixed to the 'footprint region' of the greater tubercle during the operation treatment, in addition, because rotator cuff injury repair is a 'shoulder joint contraction' process, the risk of shoulder joint adhesion after the operation is possibly increased, an ideal function is achieved in a short time, and reasonable and effective functional exercise after the operation is an important guarantee that the function of the shoulder joint is recovered to the maximum degree after the operation. However, some patients are afraid of functional exercise caused by factors such as incision cracking, pain and lack of professional exercise equipment after operation, which can cause fibrous liquid exudation of local muscles and cause adhesive scapulohumeral periarthritis.

At present, rehabilitation training after rotator cuff injury surgery has various forms, but mainly comprises three categories, namely a physiotherapy and intra-articular activity technique; training with rehabilitation instruments; three types of rehabilitation exercises without instruments have advantages and disadvantages. The existing shoulder joint trainer is not suitable for early patients after rotator cuff injury operation, is easy to cause the defects of secondary fracture of shoulder repair tendons and the like, and can not meet the requirements of the majority of patients; the shoulder training exercise without the apparatus is simple and easy to operate, and convenient to apply, but the patient compliance and the mastering method are not good enough, the training effect is not widely accepted, and the shoulder training exercise is suitable to be used as an auxiliary means of a rehabilitation training apparatus; the physical therapy and the intra-articular movement technology need the participation of a rehabilitation teacher and are not suitable for popularization and application. Therefore, the multifunctional shoulder trainer is designed to be applied to functional exercise of patients after rotator cuff injury operation, and is very important.
