Dual-task gait training often improves walking ability in stroke patients, but its effect on lower-limb coordination and the effects of different training types remains unclear. Improving lower-limb coordination could decrease fall risk during walking.
To observe the rehabilitation effect of cognitive dual-task gait training (CDTG) and motor dual-task gait training (MDTG) on lower-limb coordination during walking in subacute stroke patients.
Thirty-five subacute stroke patients were randomly assigned to the CDTG group (n = 18) and the MDTG group (n = 17), receiving cognitive dual-task gait training and motor dual-task gait training, respectively, three times a week for 4 weeks. If training benefits lower-limb coordination, a larger mean continuous relative phase (MCRP) and smaller variability (MCRPV) should be observed during walking.
After training, the MCRP of the bilateral hip joints increased during the stance phase of the affected side in both groups (P = 0.034), while the MCRPV of the bilateral hip joints decreased significantly (P = 0.024). During the swing phase of the affected side, the MCRPV between the hip and knee joints of the unaffected side (P = 0.001), the knee and ankle joints of the unaffected side (P = 0.011), and the two knee joints (P = 0.048) all decreased. There was no difference between the two groups before and after training.
Four weeks of cognitive dual-task gait training and motor dual-task gait training can effectively improve lower-limb coordination in subacute stroke patients, and there is no difference in the effects of the two training methods.
双任务步态训练通常可改善中风患者的行走能力，但其对下肢协调性的影响以及不同训练类型的效果仍不明确。改善下肢协调性可降低行走时的跌倒风险。
观察认知双任务步态训练（CDTG）和运动双任务步态训练（MDTG）对亚急性中风患者行走时下肢协调性的康复效果。
35例亚急性中风患者被随机分为CDTG组（n = 18）和MDTG组（n = 17），分别接受认知双任务步态训练和运动双任务步态训练，每周3次，共4周。如果训练有益于下肢协调性，那么在行走过程中应观察到更大的平均连续相对相位（MCRP）和更小的变异性（MCRPV）。
训练后，两组患侧站立期双侧髋关节的MCRP均增加（P = 0.034），而双侧髋关节的MCRPV显著降低（P = 0.024）。在患侧摆动期，非患侧髋关节与膝关节之间（P = 0.001）、非患侧膝关节与踝关节之间（P = 0.011）以及双侧膝关节之间（P = 0.048）的MCRPV均降低。两组训练前后无差异。
四周的认知双任务步态训练和运动双任务步态训练均可有效改善亚急性中风患者的下肢协调性，且两种训练方法的效果无差异。
