Obese people are prone to foot deformities such as flat feet. Foot management programs are important to prevent them. This study investigated the effects of two foot-ankle interventions on balance ability, foot arch, ankle strength, plantar fascia thickness, and foot functions in obese people with pes planus for four weeks. The experiment was designed as a randomized controlled trial. Twenty-four participants who met the inclusion criteria were selected, and they were randomly assigned to either a short foot group (SFG) or proprioceptive neuromuscular facilitation group (PNFG) according to foot-ankle intervention. Two interventions were commenced three times a week for 20 min over four weeks. The tests were conducted at two intervals: pre-intervention and at four weeks. The tests were conducted in the following order: the patient-specific functional scale test (PSFS), an ultrasound of the plantar fascia, the navicular drop test, balance test, and the four-way ankle strength test. Two groups showed significant differences in balance ability, foot arch, ankle strength, plantar fascia thickness, and foot functions between pre-test and post-test ( < 0.05). PNFG had significantly higher dorsiflexor and invertor strength than SFG ( < 0.05). SF and PNF interventions were effective to improve balance ability, foot arch, ankle strength, plantar fascia thickness, and foot functions in obese people with pes planus. Additionally, PNF intervention is more beneficial in increasing the dorsiflexor and invertor strength compared to SF intervention.
肥胖者容易出现扁平足等足部畸形。足部管理计划对于预防这些畸形很重要。本研究调查了两种足踝干预措施对扁平足肥胖者的平衡能力、足弓、踝关节力量、足底筋膜厚度和足部功能的影响，为期四周。该实验设计为随机对照试验。选取了24名符合纳入标准的参与者，并根据足踝干预措施将他们随机分为短足组（SFG）或本体感觉神经肌肉促进组（PNFG）。两种干预措施每周进行三次，每次20分钟，持续四周。测试在两个时间段进行：干预前和四周后。测试按以下顺序进行：患者特定功能量表测试（PSFS）、足底筋膜超声检查、舟骨下垂测试、平衡测试和四向踝关节力量测试。两组在测试前和测试后在平衡能力、足弓、踝关节力量、足底筋膜厚度和足部功能方面均显示出显著差异（<0.05）。PNFG的背屈肌和内翻肌力量明显高于SFG（<0.05）。短足和本体感觉神经肌肉促进干预措施对于改善扁平足肥胖者的平衡能力、足弓、踝关节力量、足底筋膜厚度和足部功能是有效的。此外，与短足干预相比，本体感觉神经肌肉促进干预在增加背屈肌和内翻肌力量方面更有益。
