An Active Rehabilitation System for Adhesive Capsulitis

Adhesive capsulitis is a stick of shoulder capsule that causes stick due to acute or chronic inflammation. It will cause serious impacts on patient’s daily life. Rehabilitation agencies used a shoulder abduction ladder, Pulley System for Upper Limb rehabilitation. Without electronics, networking is its drawback. The system digitizes an upper extremity rehabilitation equipment, and records the patient's rehabilitation information, such as the ability to lift the upper limbs, rehabilitation time and frequency, and so on. In addition, the system uses the Gray relational analysis to evaluate the rehabilitation efficacy. Physicians can know the patient's condition to improve his rehabilitation strategy. Patients can also know their rehabilitation effects so to encourage their rehabilitation psychology, so the arms can be recovered early. Introduction In the area of treatment of shoulder disease, the emphasis is on the reconstruction of the function of the shoulder to restore its mobility, such as shoulder extension, loosening (such as arthroscopic surgery) and physical therapy (such as ice packs, heat packs, ultrasound, Far infrared, etc.) and so on. Commonly used exercises rehabilitation [1] for Shoulder joint diseases are finger climbing wall movement, scapula activity, pendulum movement, end plate movement, pull rod movement, behind raised his hand movement; for patients who cannot lift the upper limbs, physicians or therapists will ask patients to perform rehabilitation using the Wall finger ladder and Shoulder abduction ladder. [2,3]. The traditional shortening rehabilitation apparatus in Figure 1 has the following disadvantages: (1) It does not have the ability to lift the upper extremity, the number and time of rehabilitation and other immediate measurement display device. (2) Without the function of rehabilitating information record and monitoring. (3)Without the database function, the patient's rehabilitative data cannot be stored in the storage device for a long time. (4) It cannot provide quantitative indicators as a reference to assess the effect of rehabilitation. The main purpose of this system is to construct a new set of active frozen shoulder rehabilitation systems to improve the above-mentioned shortcomings of conventional finger ladder rehabilitation equipment listed in Figure 1 to record the patient's rehabilitation information for a long time, such as the ability of the upper limbs to lift, the time and frequency of rehabilitation, and so on. System Architecture The main objective of this system is to improve some of the traditional ladder-like rehabilitation equipment, and to redesign a set of active frozen shoulder rehabilitation equipment with electronization and networking, which has the functions of rehabilitation of the upper limbs. The system architecture block diagram shown in Figure 2 has the rehabilitation of people standing in front of the rehabilitation platform, with the index finger or middle finger hard touching the bottom of the flat-panel button, and slowly moving up along the flat-panel buttons, upper extremities as much as possible, and then slowly scrolling back to the bottom flat button. Each flat button should be pressed and stay for a period of time to achieve Isometric contraction movement purposes.
