To compare the effectiveness of functional foot orthoses and unshaped (flat) orthotic material on plantar pressure redistribution, forefoot pain reduction and walking ability in rheumatoid arthritis (RA) patients.
Forty patients with RA were randomised to receive unshaped material (UM) (n = 20) or functional foot orthoses (n = 20). Plantar pressure measurement was performed with an F-scan system. Foot pain was assessed by the pain subscale of the Foot Function Index. Walking ability was assessed by the 6-min walking test. Investigations were performed at baseline, 1 week after the patient received shoes with orthoses and 6 months later.
Plantar pressures were significantly higher at painful than at non-painful foot areas. No differences in plantar pressure redistribution were found between the groups. Notable reduction of pain and improvement of activity (walking ability) was observed in both groups. Foot pain has moderate impact on the walking ability of RA patients.
The study showed no clear advantage of functional foot orthoses over UM.
比较功能性足部矫形器与未塑形（扁平）矫形材料对类风湿关节炎（RA）患者足底压力重新分布、前足疼痛减轻及行走能力的效果。
40例RA患者被随机分为两组，分别接受未塑形材料（UM）（n = 20）或功能性足部矫形器（n = 20）。使用F-scan系统进行足底压力测量。通过足部功能指数的疼痛子量表评估足部疼痛。通过6分钟步行试验评估行走能力。在基线、患者接受带矫形器的鞋子后1周以及6个月后进行调查。
疼痛足部区域的足底压力显著高于无疼痛区域。两组之间在足底压力重新分布方面未发现差异。两组均观察到疼痛显著减轻且活动（行走能力）有所改善。足部疼痛对RA患者的行走能力有中度影响。
该研究表明功能性足部矫形器相较于未塑形材料并无明显优势。
