The purposes of this study were to assess a) the effectiveness of Masai Barefoot Technology (MBT) shoe in reducing knee pain in persons with knee osteoarthritis (OA) and (b) changes in balance, ankle and knee ROM, and ankle strength compared with a high-end walking shoe for 12 wk.
The research design was a randomized controlled trial (123 subjects, knee OA). Subjects were randomized to a MBT (N = 57) or a control shoe (N = 66). A Western Ontario and McMaster Universities (WOMAC) OA index, BMI, balance, active ROM, and ankle torque were quantified at week 0, 3, 6, 9, and 12. Two-sample t-tests were done for between-group comparisons.
There was no significant difference between groups in total pain score. A significant reduction over the 12-wk period was found for both shoe conditions (-42/500 or 25.6% MBT, -46.2 or 27.1% control). There was no significant group difference in pain during walking (t = -1.09, P = 0.28). Pain during walking was significantly reduced by 5.2/100 mm in the MBT and 9.7/100 mm in the control group. Total pain showed a significant reduction for the MBT -27.4/500 (-16.6%) and the control group -28.9/500 (-17.0%) between baseline and week 3. Between week 3 and 6, there was a significant reduction for the MBT group only (-27.2/500 or -20.0%). There was a significant increase in the static balance between baseline and 12 wk in the MBT group only, although the difference between groups was not significant.
The results indicate that special shoe interventions can reduce pain in subjects with moderate knee OA.
本研究的目的是评估：a）玛氏赤足技术（MBT）鞋对减轻膝骨关节炎（OA）患者膝关节疼痛的有效性；b）与高端步行鞋相比，12周内MBT鞋在平衡、踝关节和膝关节活动度（ROM）以及踝关节力量方面的变化。
研究设计为随机对照试验（123名膝OA受试者）。受试者被随机分为MBT组（N = 57）或对照组（N = 66）。在第0、3、6、9和12周时，对西安大略和麦克马斯特大学（WOMAC）OA指数、体重指数（BMI）、平衡、主动活动度和踝关节扭矩进行量化。采用两样本t检验进行组间比较。
两组间总疼痛评分无显著差异。两种鞋类情况在12周期间均有显著降低（MBT组降低42/500或25.6%，对照组降低46.2或27.1%）。步行时疼痛的组间差异不显著（t = -1.09，P = 0.28）。MBT组步行时疼痛显著降低5.2/100 mm，对照组降低9.7/100 mm。基线至第3周期间，MBT组总疼痛显著降低27.4/500（-l6.6%），对照组降低28.9/500（-17.0%）。仅在第3至6周期间，MBT组有显著降低（-27.2/500或-20.0%）。仅MBT组在基线至12周时静态平衡有显著增加，尽管组间差异不显著。
结果表明，特殊鞋类干预可减轻中度膝OA患者的疼痛。
