Objective.确定在跑步机行走过程中获得腰椎和骨盆角运动一致性测量所需的熟悉期。一项在体研究，每2分钟重复测量10分钟。在跑步机上行走最初可能是一种不熟悉的体验。没有数据表明在测量腰椎和骨盆的角度运动之前，需要多长时间熟悉跑步机。熟悉期的影响，使用这种技术在临床测试。采用PEAK三维运动测量系统，对16名未经训练的正常受试者在自行车上以自选速度或自选速度的60%步行min，测量腰椎和骨盆的角运动。4分钟跑步机行走后，脊柱和骨盆角度测量的可靠性均大于0.83（ICC），4分钟后似乎没有增加。4分钟跑步机行走后，腰椎和骨盆角度运动的幅度没有变化，或跑步机行走2分钟后绝对差评分没有变化，在正常或慢速步行组。结论。腰椎和骨盆的角度运动是一致的4分钟后，正常受试者的跑步机行走，无论是在自我选择和缓慢的步行速度，表明这些参数的可靠测量，可以采取在那个时候.Relevanceangular运动的腰椎和骨盆可以可靠地测量在跑步机行走，提供了至少4分钟的熟悉。版权所有（C）1996爱思唯尔科学有限公司
Objective. To determine the familiarization period required to obtain consistent measurements of the angular movements of the lumbar spine and pelvis during treadmill walking.Design. An in vivo study with repeated measures every 2 min over 10 min.Background. Walking on a treadmill can initially be an unfamiliar experience. No data were available to indicate the length of time required for treadmill familiarization prior to taking measurements of the angular movements of the lumbar spine and pelvis. The familiarization period has implications for the use of this technique in clinical testing.Methods. The angular movements of the lumbar spine and pelvis were examined by the PEAK 3D motion measurement system in 16 untrained, normal subjects walking for in min on a treadmill at either self-selected or 60% of self-selected speed.Results. The reliability of the angular measurements of the spine and pelvis were all greater than 0.83 (ICC) after 4 min of treadmill walking and did not appear to increase after 4 min. No changes in the amplitudes of the angular movements of the lumbar spine and pelvis could be detected after 4 min of treadmill walking, or of the absolute difference scores beyond 2 min of treadmill walking, in either normal or slow-speed walking groups.Conclusions. Angular movements of the lumbar spine and pelvis were consistent after 4 min of treadmill walking by normal subjects, both at self-selected and slow walking speeds, indicating that reliable measurements of these parameters could be taken at that time.RelevanceAngular movements of the lumbar spine and pelvis can be reliably measured during treadmill walking, providing there has been at least 4 min of familiarization.
