Effects Of Costo-diaphragmatic Breathing Training On Upper-crossed Syndrome

Objective: Upper-crossed syndrome not only decrease the life quality of morden people,but also leading to the problem of cervical and shoulder dysfunction and breathing impairment.In theory,costo-diaphragmatic breathing training is a method to correct breathing model and improve upper trunk posture.The purpose of this investigation is to observe the influence of costo-diaphragmatic training on pateints with upper-crossed sydrome.Method: 36 female college students(not major in sports)with upper-crossed syndrome were selected as subjects,who were randomly allocated to experimental group and control group.After the intervention,there were 16 subjects in expairmental group and 15 subjects in control group.NRS,cervical active ROM,muscle quality and lung function were tested in all subjects.Under the instruction of instructors,subjects in experimented group received costo-diaphragmatic training for 4 weeks and 3 sets per day,10 times per set.While subjects in control group received no intervention and mantain ordinary life conditon.After four-week intervention,indexes above were tested again.Result:(1)Left rotation in cervical showed improvement significantly in experimental group(p<0.05).The change of flexion motion in experimental group improved more significant than control group(p<0.05).(2)The elasticity of upper trapezius improved more than before in control group(p<0.05).There were no significant changes in experimental group(p>0.05).There were no significant differences between two groups(p>0.05).(3)MVV improved significantly in experimental group(p<0.05),and improved more than control group(p<0.05).(4)NRS decreased significantly in experimental group,and improved more significantly than control group.Conclusions:(1)Costo-diaphragmatic breathing training can improve the ROM of flexion and left rotation of female college students with upper-crossed syndrome.(2)Costo-diaphragmatic breathing training can improve MVV level of female college students with upper-crossed syndrome(3)Costo-diaphragmatic breathing training can decrease pain level of famele college students with upper-crossed syndrome.
