为了保持健康的生活方式，成年人依靠他们的行走能力，同时管理挑战他们协调能力的多项任务。本研究探讨了认知双重任务对21名健康年轻人在步态启动和稳态步态时下肢肌肉活动的影响。我们利用无线肌电图传感器来测量肌肉活动，沿着与三维运动捕捉系统和测力板检测步态启动和稳态步态的阶段。参与者被要求以自己选择的速度行走，我们比较了单任务和双任务条件。我们分析了股二头肌、股外侧肌、腓肠肌和胫骨前肌的平均肌肉激活和共激活。研究结果表明，在步态启动与双任务条件下，有一个减少，平均肌肉激活和增加之间的摆动和站立肢体的平均肌肉共激活相比，单任务条件。在稳态步态中，与单任务条件相比，双任务条件下的平均肌肉激活也有所减少。当参与者在步态启动期间进行双重任务活动时，观察到平衡能力降低的早期指标。此外，在双任务稳态步态期间，膝关节稳定器肌肉表现出激活改变的迹象，导致平衡不稳定。
To maintain a healthy lifestyle, adults rely on their ability to walk while simultaneously managing multiple tasks that challenge their coordination. This study investigates the impact of cognitive dual tasks on lower-limb muscle activities in 21 healthy young adults during both gait initiation and steady-state gait. We utilized wireless electromyography sensors to measure muscle activities, along with a 3D motion capture system and force plates to detect the phases of gait initiation and steady-state gait. The participants were asked to walk at their self-selected pace, and we compared single-task and dual-task conditions. We analyzed mean muscle activation and coactivation in the biceps femoris, vastus lateralis, gastrocnemius, and tibialis anterior muscles. The findings revealed that, during gait initiation with the dual-task condition, there was a decrease in mean muscle activation and an increase in mean muscle coactivation between the swing and stance limbs compared with the single-task condition. In steady-state gait, there was also a decrease in mean muscle activation in the dual-task condition compared with the single-task condition. When participants performed dual-task activities during gait initiation, early indicators of reduced balance capability were observed. Additionally, during dual-task steady-state gait, the knee stabilizer muscles exhibited signs of altered activation, contributing to balance instability.
