We investigated the effects of full-length carbon fiber (FCF) insoles on gait, muscle activity, kinetics, and pain in patients with midfoot osteoarthritis (OA).
We enrolled 13 patients with unilateral midfoot OA (mild: Visual Analog Scale [VAS] range, 1-3; moderate, VAS range, 4-7) and healthy controls. All participants were asked to walk under two conditions: with and without FCF insole. The outcome measures were ground reaction force, quantitative gait parameters, electromyography activities and pain severity (VAS).
In the patients with moderate midfoot OA, significantly longer gait cycle and higher muscle activity of lower limb during loading-response phase were observed while walking without FCF insoles. In the mild midfoot OA group, there was no significant difference in VAS score (without, 2.0 ± 1.0 vs. with, 2.0 ± 0.5) with FCF insole use. However, significantly reduced VAS score (without, 5.5 ± 1.4 vs. with, 2.0 ± 0.5) and muscle activity of the tibialis anterior and increased muscle activity of gastrocnemius were observed in the moderate midfoot OA group by using an FCF insole (P < 0.05).
Full-length carbon fiber insoles can improve pain in individuals with moderate midfoot OA, which might be associated with changes in the kinetics and muscle activities of the lower limb. Taken together, the results of the present study suggest that FCF insoles may be used as a helpful option for midfoot OA.
我们研究了全长碳纤维（FCF）鞋垫对中足骨关节炎（OA）患者步态、肌肉活动、动力学和疼痛的影响。
我们招募了 13 名单侧中足 OA 患者（轻度：视觉模拟评分 [VAS] 范围为 1-3；中度，VAS 范围为 4-7）和健康对照组。所有参与者均要求在两种情况下行走：使用和不使用 FCF 鞋垫。评估指标为地面反作用力、定量步态参数、肌电图活动和疼痛严重程度（VAS）。
在中度中足 OA 患者中，在不使用 FCF 鞋垫行走时，观察到步态周期明显延长，负重反应期下肢肌肉活动增加。在轻度中足 OA 组中，使用 FCF 鞋垫时 VAS 评分（无，2.0 ± 1.0 与有，2.0 ± 0.5）无显著差异。然而，中度中足 OA 组使用 FCF 鞋垫后 VAS 评分（无，5.5 ± 1.4 与有，2.0 ± 0.5）显著降低，胫骨前肌和腓肠肌的肌肉活动增加（P < 0.05）。
全长碳纤维鞋垫可改善中度中足 OA 患者的疼痛，这可能与下肢动力学和肌肉活动的变化有关。综上所述，本研究结果表明，FCF 鞋垫可能是治疗中足 OA 的一种有益选择。
