Frozen shoulder is a common shoulder problem caused by inflammation of the soft tissues (bursa) of the shoulder joint, also known as “50 shoulder” or “frozen shoulder”, which usually occurs in people over 50 years old and has a higher incidence in women. According to medical literature, the real cause of frozen shoulder is unknown, but a history of trauma or long-term strain on the shoulder joint (heavy lifting/wrong posture), as well as a decrease in normal shoulder activity, such as after a stroke, surgery on tissues near the shoulder, or a fracture of the upper extremity, may increase the chance of developing frozen shoulder. Symptoms: The duration of frozen shoulder varies from a few months to several years depending on the individual’s condition, such as the presence of other factors that slow recovery. Initially, the pain in the shoulder joint increases and affects the patient’s inability to move the shoulder. After the pain decreases, the joint gradually becomes stiff and the shoulder movement is reduced and obstructed. Physical therapy for frozen shoulder includes cold/hot compresses, electrotherapy, ultrasound, manual therapy, and acupuncture to reduce pain and accelerate tissue recovery. As instructed by the physiotherapist, improve the posture of the neck and practice home exercises to maintain mobility to facilitate early recovery. Home care methods: 1. Minimize the use of the painful hand to carry heavy objects; 2. Avoid concentrating or repeatedly using the same shoulder joint when working or doing housework; alternate the use in turns; 3. Dress the painful hand first and then the good hand; 4. Avoid sleeping on the side of the painful hand; 5. Apply a hot compress for 10-15 minutes before sleeping or exercising to increase local blood circulation and reduce the pain level; 6. Exercise regularly: the pain is the heaviest Patients can do light shoulder exercises such as “pendulum exercises” to increase local blood circulation, relax muscles and reduce pain. After the pain is relieved, the patient should follow the instructions of the physical therapist to perform appropriate joint movement exercises. The following joint stretching exercises for patients with frozen shoulder are suitable for general practice to move the shoulder joint. Pendulum Exercise: Upper body in front of A, upper limbs relaxed, like a pendulum swinging in different directions for 5-8 minutes 2. Climbing Wall Exercise: Facing or recognizing the earthworm sword yelling music grain Kiri Γ. Lead the painful side upward to pull tight, stay for 10 seconds and then relax, repeat 10 times 5.
