背景：膝盖内收时刻的增加是内侧膝关节骨关节炎的危险因素之一。这项研究检查了膝关节内收时刻与自我报告的疼痛与残疾之间的关系。我们还调查了疼痛对膝关节内收时刻与步态表现和残疾之间关系的影响。方法：三十八名日本膝关节骨关节炎的日本女性参加了这项研究（6637年（41-79岁））。步态分析涉及在立场持续时间和3个姿势分子中测量外膝关节内收矩脉冲的测量。确定了日本膝关节骨关节炎的总体，疼痛和僵硬和身体功能。调查：疼痛和僵硬，身体功能和总得分与立场持续时间的膝盖内收动力脉冲正相关，初始和第二个双重双重脉冲支撑间隔和单肢支持间隔。立场持续时间内的膝盖内收力冲动与疼痛和僵硬的量表和步态速度有关。疼痛和僵硬的子量表与身体功能子量表有关。解释：我们的结果表明，膝盖内加力矩脉冲的增加，这是膝盖内侧隔室的代理，这与体重减轻活动中的疼痛增加有关作为步行，从而限制步行性能并通过降低步态速度来造成残疾。因此，步态过程中膝关节内收时脉冲的减少可能导致疼痛缓解，并且可以作为保守的治疗选择，并具有减轻疾病的潜力。 （c）2010 Elsevier Ltd.保留所有权利。
Background: An increase in the knee adduction moment is one of the risk factors of medial knee osteoarthritis. This study examined the relationship between knee adduction moment and self-reported pain and disability. We also investigated the influence of pain on the relationships between knee adduction moment and gait performance and disability.Methods: Thirty-eight Japanese women with medial knee osteoarthritis participated in this study (6637 years (41-79 years)). Gait analysis involved the measurement of the external knee adduction moment impulse in the stance duration and during 3 subdivisions of stance. The total, pain and stiffness, and physical function Japanese Knee Osteoarthritis Measure scores were determined.Findings: The pain and stiffness, physical function, and total scores were positively correlated with the knee adduction moment impulses in the stance duration, and initial and second double support interval, and single limb support interval. The knee adduction moment impulse during the stance duration was related to the pain and stiffness subscale and gait velocity. The pain and stiffness subscale was related to the physical function subscale.Interpretation: Our results suggest that increasing in the knee adduction moment impulse, a proxy for loading on the medial compartment of the knee, is related to increased pain during weight-bearing activities such as walking, thereby restricting walking performance and causing disability by reducing gait velocity. Thus, the reduction in the knee adduction moment impulse during gait may result in pain relief and may serve as a conservative treatment option with disease-modifying potential.
