Abstract：Objective To investigate the effect of cognitive-motor dual-task training on balance and gait in patients within six months post stroke.
Methods From May,2022 to April,2023,68 stroke patients in Beijing Puren Hospital were randomly divided into con-trol group(n=34)and experimental group(n=34).Both groups received conventional rehabilitation training.The control group received single-task walking training,and the experimental group received cognitive-walking dual-task training,in addition,for four weeks.They were assessed with Fugl-Meyer Assessment-Lower Extremi-ties(FMA-LE)before and after training,and measured static balance posture trajectory,stability limits,gait anal-ysis with Pro-kin and OptoGait in both single-task and dual-task states.
Results After training,the scores of FMA-UE increased in both groups(|t|>10.239,P<0.001),and no difference was found between two groups(P>0.05).In single-task state,all the parameters of balance improved in both groups after training(|t|>2.934,P<0.01),and the length of movement locus with eyes closed was longer in the experi-mental group than in the control group(t=3.330,P=0.001);all the parameters of gait improved in both groups after training(|t|>6.823,P<0.05),and the walk speed was better in the experimental group than in the control group(t=2.355,P=0.022).In dual-task state,all the parameters of balance improved in both groups after train-ing(|t|>2.472,P<0.05),expect the length of trajectory with eyes open in the control group(P>0.05),and no difference was found in other parameters between two groups(P>0.05);and all the parameters of gait improved in both groups after training(|t|>2.238,P<0.05),and the stride length and walk speed were better in the experi-mental group than in the control group(t>2.443,P<0.05).
Conclusion Cognitive-motor dual-task training can effectively improve lower limb motor function,balance function and walking ability in convalescent stroke patients,and it is superior to single-task walking training in improving some gait parameters.
