我们调查了9名健康受试者在机器人服HAL的帮助下步行后对跑步机步行运动模式的可能后效。在以3.5 km/h的速度在跑步机上行走180 s作为先决条件后，每个受试者在机器人辅助下以相同的速度行走600 s至双腿的髋关节和膝关节。受试者在辅助行走后进行正常行走300 s作为后置条件。与正常步行前相比，辅助步行期间步态周期持续时间和步长显著增加。在辅助行走期间增加的步态周期持续时间和步长在后条件开始后不久恢复到前条件期间。与此相反，在一个步骤周期内的活动范围（ROM）在最初的60秒的后处理期间逐渐增加的髋关节，但不是在膝关节。与术后最初10 s的平均髋关节ROM相比，在右腿20-60 s的4个阶段和左腿20-50 s的3个阶段中，观察到平均ROM每10 s显著增加。虽然在本研究中没有观察到强烈的后效的机器人援助的运动模式，小的适应性变化，只看到髋关节ROM在最初的正常行走阶段后立即辅助行走。
We investigated the possible aftereffects on the locomotor pattern of treadmill walking after walking with the assistance of a robot suit HAL in nine healthy subjects. After walking on a treadmill at a speed of 3.5 km/h for 180 s as a pre-condition, each subject walked with robotic assistance to the hip and knee joints of both legs at the same speed for 600 s. The subjects performed normal walking for 300 s as a post-condition after the assisted walking. Compared with normal walking in the pre-condition, gait cycle duration and step length increased significantly during the assisted walking period. The increased gait cycle duration and step length during the assisted walking period returned to that of the pre-condition period soon after the start of the post-condition. In contrast, the range of motion (ROM) within one step cycle during the initial 60 s of the post-condition period gradually increased in the hip joint, but not in the knee joint. Compared with the mean hip ROM in the initial 10 s of the post-condition, significant increases in mean ROM every 10 s were observed in 4 phases of 20-60 s each in the right leg and in 3 phases of 20-50 s each in the left leg. Although strong aftereffects of the robotic assistance on the locomotor pattern were not observed in the present study, small adaptive changes were seen only in hip ROM during the initial normal walking phase immediately after assisted walking.
