Study On The Relationship Between The Waist Abdomen Muscle Endurance And Clinical Symptoms Of Chronic Nonspecific Low Back Pain

Objective:To investigate the chronic nonspecific low back pain(CNLBP)score correlation patients with waist and abdomen muscle endurance and normal population diversity and JOA and low back pain.Method: 120 patients met the inclusion criteria were from Sichuan Province Hospital Department of orthopedics disease center to test the waist and abdomen muscle endurance to DAVID spinal rehabilitation system and their ratio was calculated.At the same time for patients with CNLBP JOA score,the three part respectively and calculate the total score(9 points): subjective symptoms,clinical signs(6 points)and daily activity limitation(14 points).The three part analysis the differences between the CNLBP group and the normal group,CNLBP group and abdomen muscle endurance and the ratio of JOA score and the correlation between each part score and total score.Results:CNLBP patients with waist and abdomen muscle endurance was significantly lower than that of the normal population,the ratio of normal abdominal muscle endurance and waist muscle endurance are the number 0.383,the standard deviation of 0.087,and the ratio of CNLBP with a standard deviation of 0.135,significantly higher than that of normal group dispersion between groups for independent T test,the difference was statistically significant(P<0.05).Spearman correlation analysis showed that: the clinical signs of subjective symptoms,JOA score,the most indicators of daily activities limited and total scores were associated with the waist muscle endurance and abdominal muscle endurance was positive(P <0.05);JOA Low back pain score in the total score and the abdomen and waist muscle endurance ratio was negatively correlated with the absolute value of the difference between 0.383(P<0.05),and no correlation between other indexes(P>0.05).Multiple linear regression analysis showed: multiple linear regression analysis showed that clinical signs of lumbar muscle force and JOA resistance back pain score in subjective symptoms,and there were positive correlation between daily activity limitation and score(r =0.494,P=0.006;r =0.276,P =0.001;r =0.398,P =0.005;r=0.365,P=0.000);there is positive correlation between the total score and abdominal muscle endurance(r =0.276,P=0.005);the ratio of waist and abdominal muscle endurance and 0.383 of the absolute value of the difference was a negative linear relationship with JOA score of low back pain score(r=-0.365,P=0.025).Conclusion: The rehabilitation system of two groups of patients DAVID spinal muscular endurance test showed that CNLBP patients with waist and abdomen muscle endurance were lower than the normal population,the ratio of abdominal muscle endurance and waist muscle endurance near 0.383 waist stress relative balance,the waist and abdomen muscle endurance and the ratio can be used as the basis for determining the clinical diagnosis and curative effect of CNLBP patients,Exercise therapy for CNLBP patients based on muscle endurance.
