客观的。确定降低步行速度是否是膝关节骨关节炎（OA）的一种策略，以减少最大的膝盖内收时刻。通过使用Kellgren/Lawrence等级评估的44例内侧胫骨内侧OA患者的自我选择的步行速度和最大的膝关节内收肌发动机与44位无症状对照受试者相匹配的疾病严重程度不同。重量。自选择的正常步行速度的差异仅解释了膝关节OA患者组最大膝关节内收时变量的8.9％。疾病的严重程度影响了内收时速度的速度关系。与无症状匹配的对照组相比，严重的OA患者中这种关系的个别斜率明显大。无论严重程度如何，膝盖OA患者之间的自我选择的步行速度和无症状控制受试者之间没有差异。但是，具有更高的OA的膝盖具有明显更大的内收力（平均+/- SD 3.80 +/- 0.89％体重x高），并且比具有较少渗透者的膝盖的变量比对更高（6.0 +/- 4.5度）。 OA（2.94 +/- 0.70％体重X高度；分别为0.0 +/- 2.9度）。结论。 OA较少重度的患者适应了步行风格，其与患有多重点OA和对照的患者不同。这种步行风格与减少速度较慢行走的内收时刻的潜力有关，并且可能与疾病严重程度降低有关。
Objective. To determine whether reducing walking speed is a strategy used by patients with knee osteoarthritis (OA) of varying disease severity to reduce the maximum knee adduction moment.Methods. Self-selected walking speeds and maximum knee adduction moments of 44 patients with medial tibiofemoral OA of varying disease severity, as assessed by using the Kellgren/Lawrence grade, were compared with those of 44 asymptomatic control subjects matched for sex, age, height, and weight.Results. Differences in self-selected normal walking speed explained only 8.9% of the variation in maximum knee adduction moment for the group of patients with knee OA. The severity of the disease influenced the adduction moment-walking speed relationship; the individual slopes of this relationship were significantly greater in patients with less severe OA than in asymptomatic matched control subjects. Self-selected walking speed did not differ between patients with knee OA, regardless of the severity, and asymptomatic control subjects. However, knees with more-severe OA had significantly greater adduction moments (mean +/- SD 3.80 +/- 0.89% body weight x height) and were in more varus alignment (6.0 +/- 4.5degrees) than knees with less-severe OA (2.94 +/- 0.70% body weight x height; and 0.0 +/- 2.9degrees, respectively).Conclusion. Patients with less-severe OA adapt a walking style that differs from that of patients with more-severe OA and controls. This walking style is associated with the potential to reduce the adduction moment when walking at slower speeds and could be linked to decreased disease severity.
