Effect Of Core Area Stabilization Training On Muscle Function Of Sports Students With Non-specific Low Back Pain

Non-specific low back pain(NSLBP)is one of the most common,costly and disability-causing health problems in adults.Recent guidelines for the treatment of low back pain emphasize that exercise therapy is the preferred treatment,and exercise therapy has a variety of forms.Based on this,this study firstly studied the changes of core muscle function of sports students with chronic nonspecific low back pain,and laid a theoretical foundation for the second part of the study.In order to provide theoretical and empirical basis for the rehabilitation treatment of non-specific low back pain,the core area stability training was used to intervene the non-specific low back pain of sports students,and the effect of core area stability training on the rehabilitation effect and muscle function of non-specific low back pain of sports students was discussed.The purpose of the first part of the experiment is to explore the changes of muscle function in the core area of non-specific low back pain sports students,and to provide theoretical basis for the second part of the study.Methods: Sports students with non-specific low back pain were recruited in the College of Physical Education of Guangxi Normal University and Lijiang College,and 20 male sports students were randomly selected;another 20 normal male sports students were randomly selected.The muscle fitness of core area was measured,including the strength of back muscle,static strength and static strength endurance(prone upper rise holding time)of core area,dynamic strength and dynamic strength endurance of abdominal muscle of core area(number of supine sit-ups),static strength and static strength endurance(supine belly rolling holding time,supine leg lifting holding time);and the back muscle and abdomen of core area were collected.Surface EMG signal of muscle.Result: The back strength,prone upper rise holding time and the number of sit-ups completed,supine abdominal curling holding time and supine leg raising holding time in the non-specific low back pain group were significantly lower than those in the normal group(P < 0.05),and the IEMG of the dorsal and abdominal muscles in the core area were significantly higher than those in the normal group(P< 0.05).CONCLUSION: The function of core muscles of non-specific low back pain sports students is obviously weaker than that of normal sports students.The second part of the experiment aims to explore the effect of stability training in the core area on non-specific low back pain and muscle function in the core area of sports students.Methods: 41 non-specific low back pain sports students were recruited in Physical Education College of Guangxi Normal University and Lijiang College,and eventually included in the study,both male and female.Forty-one sports students were divided into experimental group(core area stability training group)and control group(conventional strength training group)according to sex,andthen randomly divided into two groups.The experimental group and the control group were trained for 8 weeks.VAS score and pain symptom score were assessed,and muscle fitness in core area was assessed,including dorsal muscle strength,static strength and static strength endurance(prone upper rise holding time)and dynamic strength and dynamic strength endurance(number of sit-ups),static strength and static strength endurance(supine roll holding time,supine roll holding time)of abdominal muscle in core area.The changes of indexes such as leg-raising retention time,surface EMG signals of dorsal and abdominal muscles in the core area were collected,and the clinical efficacy was evaluated,and the cured students were followed up for 4 months.Data were collected and processed by statistics.Results:(1)After the experiment,the VAS scores and pain symptom scores of the experimental group were significantly lower than those before the experiment.The back strength,prone upper rise holding time and the number of sit-ups completed,supine abdomen curling holding time and supine leg holding time of the experimental group were all better than those before the experiment(P < 0.05).The lumbar vertebral function score and IEMG of the dorsal and abdominal muscles in the core area were also significantly lower than those before the experiment(P < 0.05).(2)After the experiment,the scores of VAS and pain symptoms in the control group were significantly lower than those before the experiment(P < 0.05).The scores of back strength,prone upper-rise holding time and the number of sit-ups completed,supine abdomen curling holding time and supine leg raising holding time in the control group were significantly better than those before the experiment(P < 0.05),and the scores of lumbar vertebral function were also significantly higher than those before the experiment(P < 0.05).(3)After the experiment,the VAS score,pain symptom score and recurrence rate of the experimental group were significantly lower than those of the control group(P < 0.05).The static holding time of supine curling abdomen and prone rising were significantly longer than those of the control group(P < 0.05).The IEMG of lumbar spine function score,back of core area and abdominal muscle group were significantly lower than those of the control group(P <0.05).In addition,the evaluation of clinical efficacy grade was also significantly lower.It is superior to the control group.CONCLUSION:(1)Core area stability training can alleviate pain,improve lumbar function,and enhance core muscle strength and endurance of non-specific low back pain sports students;(2)Core area stability training is superior to routine strength training in the efficacy of non-specific low back pain and the improvement of core area muscle function;and the recurrence rate is also lower than routine strength training...
