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 control 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 Extremities (FMA-LE) before and after training, and measured static balance posture trajectory, stability limits, gait analysis 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 experimental 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 training (|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 experimental 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.
