The Function Analysis And The Application Research Of Core Muscles In The Occupational Low Back Pain Patients

With the development of social economy, people's quality of life have been improving, while their bodies' health problems have also been highlighted. Currently in clinic, the incidence of low back pain which has become one of the most common disease rank only second to the cold, and people with low back pain has a tendency to gradually close to the young. The occupational low back pain are associated with personal career. Due to the nature of work, people's physical need to keep the same posture so that spinal load overweight and maintaining the stability of the core muscles are under stress for a long time, especially the low back muscle fatigue appear easily over time leading to physical symptoms of low back pain. Low back pain and restricted movement cause the fall of professionals working ability and professional quality of life.In view of the current severe social situation of low back pain, this study aims to determine the influence of the occupational low back pain on professional crowd muscle group and the corresponding prevention measures. This study selected rehabilitation therapists as experimental group from rehabilitation center of Baoding city and selected healthy college students as control group from Bebei university. Based on the analyzing of two groups, this study advances the corresponding prevention measures. The main studying contents of this article includes these aspects:First, based on the methods of surface electromyography technology, this study collected the surface electromyogram signal of the core muscles from rehabilitation therapists and healthy people in six kinds of action. By extracting and analyzing the time domain characteristic value of sEMG- root mean square and integral electrical values, this study compare the sEMG changes of patients group and control group subjects' core muscles.Second, regarding the influence of occupational low back pain on the core muscles, this paper puts forward a kind of rhythmic activity of waist and back muscle- riding a bike. This research adopts Fast Fourier Transform algorithm obtaining the power spectrum and extracts the sEMG frequency domain characteristic values- the Median Frequency. Through analyzing the spinal muscular activity state changes of subjects in the course of cycling, this article proved that riding a bike could produce certain incentives to the low back. At the same time the conclusion also provide certain theoretical support for peoples' daily bicycle exercise and rehabilitation.Third, the pathogenesis of low back pain is complex, but the wrong body posture is one of the important causes of low back pain. Thus, adjusting the body posture is very important to prevent the onset of low back pain. Based on the above two chapters, this article verifies the feasibility of using squatting down instead of bending forward to prevent back muscles from low back pain. Similarly, this research adopts Fast Fourier Transform algorithm obtaining the power spectrum of sEMG from erector spinae and vastus lateralis and extracts the sEMG frequency domain characteristic values- the Median Frequency. By analyzing the muscle activities of ES and VL in the two position state, the results show that VL are more prone to fatigue than ES in the process of squatting down, however, ES is easier to produce fatigue in the process of bending forward. This conclusion verifies that to a certain extent, squatting down can transfer the waist muscle strength so that protect the waist.This research provides certain theory basis and support for rehabilitation medicine and rehabilitation exercise in the occupational low back pain patients.
