Harm caused by long-term stiffness of the trapezius muscle
Prolonged stiffness of the trapezius muscle may lead to conditions such as muscle strain, shoulder periarthritis, and cervical spondylosis, causing discomfort in the neck and shoulder areas.
1. Muscle Strain
Chronic stiffness of the trapezius muscle leads to sustained muscle tension. Without proper recovery, this can easily trigger local aseptic inflammation, resulting in muscle strain and symptoms such as recurrent local soreness and restricted movement.
2. Shoulder Periarthritis
Prolonged trapezius stiffness can cause degeneration of shoulder joint soft tissues and reduced load-bearing capacity, leading to chronic overuse injury. If not effectively treated, it may damage the shoulder joint capsule, as well as surrounding ligaments, tendons, and bursae, resulting in shoulder periarthritis, which manifests as shoulder pain and limited range of motion in the shoulder joint.
3. Cervical Spondylosis
Long-term trapezius muscle stiffness can impair local blood circulation, potentially accelerating degeneration of the cervical intervertebral discs, leading to narrowed disc spaces and decreased cervical spine stability. This may ultimately compress or irritate adjacent spinal cord, nerves, and blood vessels, causing cervical spondylosis and symptoms such as neck and shoulder pain, sensory disturbances, and restricted movement.
In addition, prolonged trapezius muscle stiffness may also contribute to cervicobrachial syndrome, causing neck and shoulder pain, as well as arm pain. Patients can improve symptoms through treatments such as massage and stretching of the trapezius muscle under medical guidance.
