Abstract:
Objective To investigate whether the combination of conventional respiratory training and articulatory visual feedback training can improve respiratory function and diaphragmatic function in stroke patients.Methods This single-blind randomized controlled trial recruited a total of 30 stroke patients who were admitted to Department of Rehabilitation Medicine,Zhongshan Hospital,Fudan University,from Nov 2022 to Aug 2023,and divided them into two groups:a experimental group(n=15)and a control group(n=15).The experimental group received conventional respiratory training combined with articulatory visual feedback training,and the control group received conventional respiratory training.The training in the 2 groups was conducted 5 times per week for 4 weeks.Results Both groups significantly improved in maximum inspiratory pressure(MIP),peak inspiratory flow(PIF),maximum phonation time(MPT),maximum counting ability(MCA),and peak expiratory flow(PEF)in each of the two groups improved significantly after training(P<0.05).After training,compared with the control group,the experimental group showed significant differences in MIP[(46.04±13.58)cmH2O vs.(63.46±16.96)cmH2O;P=0.004;95%CI:-28.91,-5.93;effect size(ES)=1.13],PIF[(144.00±43.81)L/min vs.(190.20±75.01)L/min;P=0.049;95%CI:-1.54,0;ES=0.75],MCA[(7.06±3.25)s vs.(10.30±4.89)s;P=0.041;95%CI:-6.34,-0.13;ES=0.77],forced vital capacity(FVC)[(1.74±0.76)L vs.(2.26±0.57)L;P=0.04;95%CI:-1.03,-0.03;ES=0.77],forced expiratory volume in one second(FEV1)[(1.10±0.40)L vs.(1.60±0.50)L;P=0.004;95%CI:-0.85,-0.18;ES=1.1],and PEF[(83.40(55.80)L/min vs.171.12(94.80)L/min;P=0.012)].However,there were no statistically significant differences after training between the two groups in the maximum phonation time(MPT),vital capacity(VC),maximum voluntary ventilation(MVV),diaphragm mobility of the nonparetic side and paretic side,thickening fraction of the nonparetic side and paretic side.Conclusion Compared with conventional respiratory training alone,the combination of articulatory visual feedback training with conventional respiratory training is more effective in enhancing respiratory and lung function in stroke.
