Summary of core muscle strength and surface electromyography in patients with chronic nonspecific low back pain

In recent years, with the changes in people's lifestyles, the prevalence of non-specific low back pain is on the rise in China. Among them, middle-aged and elderly women, postpartum women, athletes and long-term sitting workers are the majority. If the patient does not receive effective treatment, it will not only seriously endanger personal health and cause unnecessary troubles to work and life, but also increase the medical burden and cause serious social and economic problems. At present, many scholars believe that the decline of lumbar spine stability and the changes in the biomechanical structure of the human body are one of the important mechanisms for the occurrence and development of chronic non-specific low back pain. Due to the special anatomical structure, the lumbar spine becomes the most vulnerable part of the spine. When the patient is in a state of poor posture for a long time, the nucleus and muscles attached to the lumbar spine, especially the transverse abdominis and multifidus muscles, will appear to varying degrees." "Fatigue", when "fatigue" reaches a certain level, "disuse" or even atrophy occurs, muscle strength will further decrease, and the stability of the lumbar spine will decrease, causing abnormalities between the lumbar muscles and nerve signal transmission, and eventually causing pain. Therefore, it is of great significance to study the relationship between non-specific low back pain, waist and abdominal muscle strength, electromyography and pain. This study studied the relationship between the waist and abdominal muscle strength, myoelectric performance and pain in patients with non-specific low back pain. The conclusions were drawn from the research results, and at the theoretical level, it provides a theoretical basis for the clinical treatment of non-specific low back pain. On the practical level, it is helpful to remind people to maintain lumbar spine stability and prevent chronic low back pain.
