反馈式吸气肌训练对脑卒中患者平衡及步行能力的影响OA

Objective:To observe the effects of feedback inspiratory muscle training on balance and walking ability in stroke patients,and to analyze the correlation between the inspiratory function indicator maximum inspiratory pressure(MIP)and balance and walking ability.Methods:A total of 40 hemiplegic patients with a stroke duration of 3 to 12 months were enrolled and randomly divided into an experimental group(n=20)and a control group(n=20)using a random number table.Both groups received conventional treatment(including range of motion training,balance training,etc.).The experimental group additionally received feedback inspiratory muscle training twice daily,30 sets per session.The Berg Balance Scale(BBS),a balance assessment and training system,the Timed"Up&Go"(TUG)test,and MIP were used to evaluate outcomes before and after the intervention.Results:After 8 weeks of intervention,both groups showed statistically significant changes in BBS scores,center of gravity displacement trajectory length under eyes-open and eyes-closed conditions,ellipse area,stability index,and TUG(P<0.05).After the intervention,the experimental group demonstrated significantly greater improvements in center of gravity displacement trajectory length under the eyes-open condition,ellipse area,and TUG time compared with the control group(P<0.05).MIP was negatively correlated with center of gravity displacement trajectory length during static standing balance(r=-0.794,P<0.001)and positively correlated with the stability index(r=0.668,P<0.001).Conclusion:Balance trainer-based training combined with feedback inspiratory muscle training can better improve balance and walking ability in stroke patients.Feedback inspiratory muscle training has clinical application value in improving balance and walking ability in stroke patients.
