Effect Of Floss Band Training On Shoulder Joint Function In Patients With Rotator Cuff Injury

Objectives: Rotator cuff injury is a common sports injury,accounting for 17%-41%of shoulder disorders.Currently,the main conservative treatments for rotator cuff injury are exercise therapy,physical therapy and medication,but there are limitations in their clinical application and there is no optimal treatment plan.Recent studies have found that this is a very popular strategy for athletes by using floss band,not only increase joint range of motion,strengthen injury prevention and rehabilitation but also improve athletic performance.Therefore,in this study,the effects of floss band training on pain,joint mobility,shoulder function,muscle strength,and quality of life in patients with rotator cuff injury were observed by contrasting them with conventional rehabilitation training in order to offer patients with rotator cuff injury some new ideas of rehabilitation and promote the further application of floss band training in musculoskeletal disorders.Methods: Thirty-eight subjects with rotator cuff injury were screened by recruitment and randomly allocated to control and experimental groups:（1）the control group underwent conventional rehabilitation training（arthrodesis + rotator cuff strength training）3 times a week for 6 weeks;（2）the experimental group underwent flossband training（flossband + arthrodesis + rotator cuff strength training）3 times a week for 6weeks.Both groups were systematically evaluated before and after the 6-week intervention,including: visual pain analogue scoring scale（VAS）,shoulder mobility（ROM）,shoulder pain and dysfunction scale（SPADI）,isomed2000 isometric muscle strength test,and quality of life scale（SF-36）.The data obtained were processed by SPSS version 26.0 statistical software,and t-test and non-parametric test were used for statistical analysis.P<0.05 indicates that the difference is significant.Results:（1）A total of 38 subjects eventually completed the experimental study,19 in each group.Before the intervention,all evaluation indexes of the differences between the two groups were no statistical significance（P>0.05）.（2）Pain assessment:（1）the values in VAS and SPADI pain scale were significantly lower in both control and experimental groups contrasted with those before the intervention（P<0.05）;（2）compared between groups,the pain scores of subjects in the experimental group after 6 weeks of intervention were prominently superior to the control group（P<0.05）.（3）Shoulder joint mobility assessment:（1）The joint mobility of both the control group and the experimental group was prominently improved contrasted with that before the intervention（P<0.05）;（2）After 6 weeks of intervention,the improvement in mobility of the subjects in the experimental group was prominently superior to the control group（P<0.05）.（4）Shoulder joint dysfunction assessment:（1）The dysfunction scores of both control and experimental groups were prominently improved contrasted with those before the intervention（P<0.05）;（2）compared between groups,the improvement of dysfunction scores of subjects in the experimental group was prominently superior to the control group after 6 weeks of intervention（P<0.05）.（5）Isometric muscle strength assessment:（1）The shoulder joint forward flexion,abduction,internal rotation,external rotation peak moments and maximum work done in the control and experimental groups were prominently increased contrasted with those before the intervention（P<0.05）,and no obvious difference could be found in the two groups（P>0.05）.（2）The external to internal rotation ratio increased in both the control and experimental groups compared with that before the intervention,and all were within the normal range（0.70～0.80）.（6）Quality of life assessment: all SF-36 scores in both control and experimental groups increased prominently contrasted with those before the intervention（P<0.05）,and the difference between the groups was not statistically prominent（P>0.05）,but in terms of increase,the experimental group showed a more significant upward advantage.Conclusion:（1）Both floss band training and conventional rehabilitation training prominently improved the pain,increased the patients with rotator cuff injury in range of motion,shoulder function and muscle strength,and life quality.（2）Compared with conventional rehabilitation training,floss band training was more effective in improving the pain,increasing the range of motion and improving the function of the rotator cuff injury.（3）There was no significant difference in the improvement of muscle strength and life quality between floss band training and conventional rehabilitation training for patients with rotator cuff injury,but floss band training was more advantageous to a certain extent.
