This paper reports the results of a study of the gait of 102 patients with osteoarthritis of the knee. Functional status was measured by a 6-min test of walking distance; the stride characteristics associated with the walk test were assessed. Stride characteristics were measured by a Stride Analyzer. Patients were randomized to an 8-week educational and walking program (the intervention group) or to a weekly telephone survey (the control group). The intervention group patients had a 15% increase in walking distance (P < 0.0001) and increases of 9.1% in stride length at free walking speeds (P < 0.007) and 17% in stride length at fast walking speeds (P < 0.01) compared to the control group. The results of this study have shown that the walking and educational program was effective in improving gait function in patients with osteoarthritis of the knee.
本文报告了一项对102例膝骨关节炎患者步态的研究结果。通过6分钟步行距离测试来衡量功能状态；评估与步行测试相关的步幅特征。步幅特征由步幅分析仪测量。患者被随机分为8周的教育和步行计划组（干预组）或每周电话调查组（对照组）。与对照组相比，干预组患者的步行距离增加了15%（P<0.0001），自由步行速度下步幅长度增加了9.1%（P<0.007），快速步行速度下步幅长度增加了17%（P<0.01）。这项研究结果表明，步行和教育计划对改善膝骨关节炎患者的步态功能有效。
