Quadrupedal nature of arm and leg coupling during rhythmic human locomotion

虽然大脑是身体的指挥中心，但脊髓内的连接调节着有节奏的活动，如行走。大脑有助于这种运动，但脊髓回路可以自己协调肌肉活动，依靠肢体运动的反馈来调节模式。虽然我们人类是两足动物，用两条腿走路，但有人建议我们在走路时使用四足协调。最近，我的研究已经解决了人类在行走过程中手臂之间以及手臂和腿之间的协调问题。总体情况表明，与其他动物非常相似的控制机制有助于人类行走时看到的有节奏的手臂和腿部运动模式。我的研究重点是了解神经系统在有节奏的运动任务中协调手臂和腿的具体方式，如步行，跑步和游泳。* 最终，从这项研究中获得的新知识可能会带来更有效的方法来改善大脑或脊髓损伤后的运动协调。****

While the brain is the body's command centre, connections within the spinal cord regulate rhythmic activities like walking. The brain contributes to such movements, but spinal cord circuits can coordinate muscle activity on their own, relying on feedback from moving limbs to regulate the pattern.****Although we humans are bipeds and walk on two legs it has been suggested that we use quadrupedal coordination during walking. Recently, the issue of coordination between the arms and between the arms and legs of humans during walking has been addressed by my research.****The overall picture suggests that control mechanisms very similar to those found in other animals contribute to the pattern of rhythmic arm and leg movement seen during human walking.****The focus of my research is on understanding the specific way in which the nervous system coordinates the arms and legs during rhythmic movement tasks like walking, running, and swimming. ****Eventually, new knowledge gained from this research may lead to more effective methods of improving motor coordination following brain or spinal cord injury. ****
