Neck, shoulder, lumbar and leg pain are a group of symptoms. The common clinical symptoms are: cervical spine syndrome, fallen pillow, shoulder periarthritis, lumbar disc herniation, acute lumbar sprain, posterior lumbar joint dysfunction and chronic lumbar muscle strain. Cervical spine syndrome is referred to as cervical spondylosis. It is mainly a joint dysfunction caused by degeneration of the cervical spine due to acute injury or chronic strain on the back of the neck, or secondary injury to the soft tissues around the cervical spine due to damage to the bones and joints of the cervical spine such as osteophytes. The main pathological change of frozen shoulder is chronic degeneration of the soft tissues around the joint. It can be secondary to cervicothoracic spine osteoarthrosis or periapical tenosynovitis, bursitis and fibrositis, and is related to local wind and cold and injury; sometimes it is also related to poor sleeping posture and endocrine disorders. Acute lumbar sprain is mainly due to improper body posture, improper force, or fall, weight-bearing, strenuous exercise, bending over for objects and impact on the lumbar region during activities. As a result, the lumbosacral muscles, fascia or ligaments are damaged and cause lumbago. Chronic lumbar muscle strain is a common type of low back pain. It can be the sequelae of acute lumbar sprain due to lack of adequate treatment. It is caused by local congestion and exudation after ligament or fascia injury, and without adequate treatment. The fibrous degeneration occurs, resulting in adhesions within the muscle ligaments or joints. This causes chronic low back pain and lumbar synostosis, which is caused by the rupture of the fibrous ring between the two lumbar vertebrae or the treatment of lumbar and sacral vertebrae, and the protrusion of the nucleus pulposus, which compresses the nerve roots of the spinal cord. Due to trauma and degenerative degeneration of the intervertebral disc, causing the rupture of the intervertebral disc fibrous annulus and the protrusion of indistinguishable tissues into the fire intervertebral foramen of the spinal canal, the symptoms of nerve root irritation can be produced. Physical therapy is the treatment of choice for neck, shoulder, lumbar and leg pain. Once the neck, shoulder, lumbar and leg pain has attacked, it is difficult for drugs to act locally and pain relief is poor. Physiotherapy can act directly on the local area to improve circulation, strengthen the nutritional status of local tissues, relieve muscle spasm, reduce pain, reduce inflammatory exudation, eliminate edema and adhesions, reduce or eliminate nerve irritation symptoms; strengthen muscle strength, reduce muscle atrophy, prevent muscle contracture, and improve joint mobility.
