Unbalanced movements between the bilateral sides may lead to dyskinesia and reduced motor function. The upper limbs are the most complex joints with different rate of usage between the limbs. The dominant side is repeatedly used more than the contralateral side for better dexterity and musculoskeletal utility. Such imbalance between the two bilateral sides may lead to further difference in movement ability. This study aimed to observe the feasibility of the mirror feedback method in the upper limb movements in the old people with mild cognitive impairment. Twenty-seven-old people with history of stroke were selected. Motion sensors were used to assess the location and motion of two limbs in synchronized lateral raise that include the abduction and adduction motions during the mirror feedback and no feedback trials. The results of the mirror feedback showed comparatively similar motions between the left and right upper limbs. The results of the study may indicate possible recommendation of mirror feedback method for synchronizing exercise motion of the upper limbs for the old people with mild cognitive impairment.
双侧之间的不平衡运动可能导致运动障碍和运动功能下降。上肢是最复杂的关节，肢体之间的使用频率不同。优势侧比非优势侧反复使用得更多，以获得更好的灵活性和肌肉骨骼效用。双侧之间的这种不平衡可能导致运动能力进一步差异。本研究旨在观察镜像反馈方法在轻度认知障碍老年人上肢运动中的可行性。选取了27名有中风病史的老年人。使用运动传感器评估双侧肢体在同步侧举中的位置和运动，包括镜像反馈和无反馈试验期间的外展和内收运动。镜像反馈结果显示左右上肢运动相对相似。研究结果可能表明，对于轻度认知障碍老年人，镜像反馈方法可能是同步上肢运动锻炼的推荐方法。
