Lumbar muscle strain, a common clinical disease, also known as functional lumbago, chronic lower back injury, lumbar gluteal fasciitis, etc., is actually a chronic injury inflammation of the lumbar muscles and their attachment points fascia or periosteum, is one of the common causes of lumbar pain, strain injury is mostly chronic onset, the main symptoms are lumbar or lumbosacral distension, soreness, recurrent episodes, pain can change with climate change or the degree of exertion, such as daytime exertion aggravated, after rest The pain can be aggravated by daytime exertion, but can be alleviated after rest. Differential diagnosis The disease is similar to the symptoms of lumbar disc herniation, and is mainly differentiated from the following aspects. 1, patients with lumbar muscle strain mostly have only lumbar pain, while lumbar disc herniation is mostly accompanied by leg pain in addition to lumbar pain; 2, pressure points of lumbar muscle strain are mostly on the sides of the spine, but pressure points of lumbar disc herniation are mostly in the middle of the spine or poorly described; 3, patients with lumbar muscle strain generally have little effect on lumbar mobility, and usually low back pain is triggered and intensified when getting up in the morning or standing up after sitting for a long time, and can be significantly relieved after activity. However, patients with lumbar disc herniation often have difficulty bending in at least one direction, such as forward, backward, left and right. Improve the usual movements and posture to prevent lumbar muscle strain Improper posture in daily life such as standing, sitting, bending and picking up things may have an effect on the muscles of the lumbar region, and correct posture is the key to preventing lumbar muscle strain (some exercises are similar to lumbar disc herniation). Correct and incorrect posture for picking up objects (above) Correct and incorrect posture for sitting can be done by putting a small cushion between the back of the chair and the back, as shown below. Correct and incorrect standing posture treatment 1. Take proper rest, change your posture regularly (as shown above), and avoid bending over to hold objects, etc. Use a lumbar brace at work if necessary (it should be lifted at rest to avoid causing disuse muscle atrophy and further aggravating the instability of the lumbar segment of the spine). At the same time, lumbar muscle strength should be trained (below) to increase the compensatory adjustment of undamaged muscles. Those who have the conditions can use the exercise ball (below) Another better way is to stretch, raise the arms, body back, stretch the waist, and the opposite of the posture of ambulation. Moreover, too soft lying equipment to keep the back muscles contracted for a long time, it is difficult to get a good rest. Patients with chronic low back pain are recommended to sleep on a hard bed, because when sleeping on a hard bed, the thoracic back and sacrum of the human body are on the bed, the waist is suspended, maintaining the physiological forward flexion of the waist, and this position puts the lumbar muscles in the best resting position, which is conducive to the relief of low back pain. 2.Physiotherapy for pressure pain areas, as well as massage and tui-na with appropriate techniques and strength (if the cause of low back pain has not been determined, this method should be chosen with caution). 3.Adrenocorticotropic hormone injection treatment at the pressure pain site. 4.Patients whose pain obviously affects their work can use non-steroidal anti-inflammatory drugs, local topical muscle relaxants and sedatives like diazepam as appropriate.
