本研究的目的是探讨听觉节律和手臂运动对中风患者在行走过程中节段间协调的影响。11名受试者在跑步机上行走：（1）在系统性速度增加期间，（0.22-1.52米/秒），（2）在节拍器频率系统性增加期间，（1-2.2 Hz），以及（3）具有指令：在节拍器频率的系统性增加过程中，（1 ~ 2.2Hz），测量上、下身体节段的运动幅度、臂、腿运动的频率协调性、上、下身体节段之间的相位关系。随着节拍移动手臂和腿导致手臂摆动沿着增加，手臂和腿之间的频率协调为1：1，并且观察到骨盆和胸部横向旋转之间的相位关系更大。口头指示移动手臂节拍器的节拍导致增加手臂摆动，增加步幅，但需要进一步的研究来检查手臂运动的变化动力学，以提高上肢运动功能障碍如何影响行走过程中的节段间协调的理解。(C)2006 Elsevier B.

The objective was to investigate the effects of auditory rhythms and arm movement on inter-segmental coordination during walking in persons who have suffered a stroke. Eleven subjects walked on a treadmill: (1) during systematic increases in velocity (0.22-1.52 m/s), (2) with instructions to 'step to the beat' during systematic increases in metronome frequency (1-2.2 Hz), and (3) with instructions: 'move the arms and legs to the beat' during systematic increases in metronome frequency (1-2.2 Hz).Movement amplitude of upper and lower body segments, frequency coordination between arm and leg movements, phase relation between upper and lower body segments were measured. Moving the arms and legs to the beat resulted in increased arm swing along with 1:1 frequency coordination between the arm and leg, and a more out-of-phase relation between transverse pelvic and thoracic rotation was observed with larger pelvic and thoracic rotations. Verbal instructions to move the arms to the beat of a metronome leads to increased arm swing, increased stride length, but further study is needed to examine the dynamics of the changes in arm movement, to enhance understanding of how upper extremity movement dysfunction affects inter-segmental coordination during walking.
