Effect Of Nustep-T4 Trainning On Pulmonary Rehabilitation In Patients With Chronic Obstructive Pulmonary Disease In Stable Phase

Objective:Explore the effect of Nustep-T4 training on pulmonary rehabilitation in patients with COPD in stable phase and provide new techniques and methods for pulmonary rehabilitation in patients with COPD.Method:64 patients with COPD in stable phase were selected and randomly divided into a control group and an experimental group（Nustep-T4 training group）with 32 samples in each group.All enrolled patients received standard COPD medication and corresponding pulmonary rehabilitation knowledge and education;the control group maintained daily activity on this basis;On this basis,the experimental group also received Nustep-T4 training for eight weeks and two times a week.Pulmonary function assessment（lung function measurements）,exercise endurance assessment（6MWD）,quality of life assessment（CAT）,assessment of dyspnea（mMRC、Borg）,and BODE index were performed before and after the intervention in both groups.Results:1.Pulmonary function assessment:（1）FEV₁/FVC（%）:before the intervention in the control group（43.09±7.25）%and after the intervention（42.88±6.81）%;before the intervention in the experimental group（44.87±7.93）%and after the intervention（43.80±8.03）%.There was no significant difference in FEV₁/FVC between the two groups before intervention（P>0.05）.（2）FEV₁（L）:before the intervention in the control group（0.98±0.34）L and after the intervention（0.96±0.33）L;before the intervention in the experimental group（0.99±0.3）L and after the intervention（1.02±0.28）L.There was no significant difference in FEV₁between the two groups after intervention（P>0.05）.2.Exercise endurance assessment（6 MWD）:before the intervention in the control group 357.5（310³80）m,after the intervention 350（305³71.25）m;before the intervention in the experimental group362.5（300⁴00）m,after the intervention 422.5（348.75⁴60）m.The6 MWD in the experimental group significantly increased after the intervention,and the exercise endurance increased,the difference was statistically significant（P<0.05）;between the groups,the 6MWD after the intervention in the experimental group was significantly increased after the intervention,the difference was statistically significant（P<0.05）.3.The quality of life assessment（CAT）:before the intervention in the control group（20.77±4.88）and after the intervention（21.03±4.75）;before the intervention in the experimental group（19.70±3.85）,and after the intervention（14.23±3,45）.After the intervention of the experimental group,the CAT score was lower than before the intervention,and the quality of life was improved compared with before（P<0.05）.Compared between the groups,the score of the CAT after the intervention of the experimental group was lower than that of the control group and the difference was statistically significant.（P<0.05）.4.Assessment of dyspnea:（1）mMRC:before the intervention in the control group 2（2³）and after the intervention 2（2³）;before the intervention in the experimental group 2（2³）and after the intervention1（1²）.The mMRC score was lower after the intervention in the experimental group than before the intervention,and the symptoms of dyspnea were improved earlier than before（P<0.05）.The comparison between the two groups showed that the mMRC score after the intervention in the experimental group was lower than that after the intervention in the control group.The difference was statistically significant.（P<0.05）.（2）Borg:before the intervention in the control group 5（4⁶）and after the intervention 5（4⁶）;before the intervention in the experimental group 5（4⁵）and after the intervention 3（3⁴）.The Borg score was lower in the experimental group than before the intervention,and the symptoms of dyspnea were improved earlier than before（P<0.05）.The Borg score after the intervention in the experimental group was lower than that after the intervention in the control group,and the difference was statistically significant（P<0.05）.5.BODE index:before the intervention in the control group 4.5（3⁶）and after the intervention 5（3⁶）;before the intervention in the experimental group 4（3.75⁵）and after the intervention 3（3⁴）.After the intervention of the experimental group,the BODE index decreased compared with that before the intervention,suggesting that the severity of COPD patients was improved compared with before（P<0.05）.After the intervention of the experimental group,the BODE index decreased after the intervention of the experimental group.The difference was statistically significant（P<0.05）.Conclusion:Nustep-T4 training can reduce the symptoms of dyspnea in patients with COPD in stable phase,improve exercise endurance and quality of life,and there is no significant improvement in Pulmonary function of patients.
