Study On The Effect Of Sling Exercise Therapy Cure Chronic Low Back Pain

Objective:To investigate the efficacy of the sling exercise therapy cure chronic low back pain.Methods:15 healthy subjects aged 31⁴0 years old and15 healthy subjects aged 41⁵0 years old were recruited,who were divided into A₁ group and A₂ group respectively.30 cases of patients aged 31⁴0years old with chronic low back pain and 30 cases of patients aged 41⁵0years old with chronic low back pain who were treated in department of rehabilitation medicine of the first hospital of Shanxi Medical Universityfrom July 2016 to December 2017 were selected.The patients aged 31⁴0 years old randomly divided into B₁ group（15 cases）and C₁ group（15 cases）and the patients aged 41⁵0 years old randomlydivided into B₂ group（15 cases）and C₂ group（15 cases）.B₁ groupand B₂ group received conventional drug treatment,C₁ groupand C₂ group treated with the SET.Before and 4 weeks after treatment,through the MyoTrac Encoder instrument measuring FR ratio of spinal erectors of the subjects Measuring the patients’subjective index of the degree of pain,dysfunction and lumbar dysfunction degree by VAS,ODI and RMQ scale.Through the tape measure measuring lumbar active motion（the Range of motion,ROM）,with manual muscle testing method to assess the subjects trunk inflexional and outstretched strength,with a stopwatch to determine subjects trunk inflexional and outstretched endurance.Results:（1）4 weeks after treatment,FR ratio of spinal erectors,trunk inflexional and outstretched strength,trunk inflexional and outstretched endurance,each direction of lumbar motion,ODI score,RMQ score,VAS score of B₁ group and C₁ group were significantly ameliorated（P<0.01）,and the C₁ group amelioratedmore significantly（P<0.05）,which was closer to the A₁ group.（2）4 weeks after treatment,FR ratio of spinal erectors,trunk inflexional and outstretched strength,trunk inflexional and outstretched endurance,each direction of lumbar motion,ODI score,RMQ score,VAS score of B₂ group and C₂ group were significantly ameliorated（P<0.01）,and the C₂ group ameliorated more significantly（P<0.05）,which was closer to the A₂ group.（3）After 4 weeks of treatment,B₁ group was significantly better than that of B₂ group in lumbar flexor and extensor muscle endurance and lumbar left flexion ROM（P<0.05）.（4）After 4 weeks of treatment,C₁ group was significantly better than that of C₂ group inlumbar extensor muscle endurance,lumbar left and right flexion ROM,lumbar stretching back ROM,ODI score and RMQ score（p<0.05）.（5）The FR ratio of the spinal erectors was negatively correlated with the ODI score,VAS score and RMQ score,and was positively correlated with the lumbar anterior flexion ROM and the lumbar extension ROM.Conclusion:（1）The routine therapy and SET have promoting effect for ameliorated the patients’FR ratio of spinal erectors,trunk inflexional and outstretched strength,trunk inflexional and outstretched endurance,each direction of lumbar motion,lumbar disability and degree of pain,and the SET is better.（2）Under conventional drug therapy,the younger patients with chronic low back pain,the more obvious the improvement of the flexor and extensor muscle endurance of the trunk and the left flexion of the lumbar spine.（3）In the treatment of SET,the younger patients with chronic low back pain,the better of the lumbar extensor muscle endurance,lumbar left and right flexion ROM,lumbar stretching back ROM and lumbar disability.（4）FR ratio of spinal erectors was increased with the decrease of lumbar disability and degree of pain,and increased with the increase of lumbar anterior flexion ROM and lumbar extension ROM.
