Abstract

Background

Posterior tibialis tendon dysfunction is a chronic musculoskeletal disorder characterized by a progressive flatfoot deformity which negatively impacts health-related quality of life. Custom foot orthoses modify walking biomechanics in individuals with posterior tibialis tendon dysfunction, but no studies have investigated their effects on stair climbing biomechanics in this population. This cross-sectional study aimed to compare the effects of prefabricated foot orthoses and two models of custom foot orthoses on the biomechanics of individuals with posterior tibialis tendon dysfunction during stair climbing.

Methods

Fourteen individuals with painful posterior tibialis tendon dysfunction were recruited to undertake a stair climbing task under four experimental conditions: shoes alone, prefabricated foot orthoses, neutral custom foot orthoses and custom varus foot orthoses with a 5° medial wedge and a 4 mm medial heel skive. Hip, knee, ankle and foot angles and moments were compared between conditions, using one-dimensional statistical non-parametric mapping.

Findings

Forefoot dorsiflexion was decreased for neutral custom foot orthoses compared to shoes (P < 0.001). Both custom foot orthoses decreased hindfoot eversion compared to shoes (P < 0.001). Greater ankle eversion moments were observed for both custom foot orthoses compared to shoes (P < 0.001) and prefabricated foot orthoses (neutral custom: P < 0.001).

Interpretation

Neutral custom and custom varus foot orthoses seem appropriate to attenuate biomechanical deficits in individuals with posterior tibialis tendon dysfunction. Longer-term effects of foot orthoses on lower limb biomechanics and clinical meaningfulness of these changes remain to be determined.

预制和定制足矫形器对爬楼梯时胫骨后肌腱功能障碍患者下肢生物力学的影响。

背景：胫后肌腱功能障碍是一种慢性肌肉骨骼疾病，其特征是进行性扁平足畸形，对健康相关的生活质量产生负面影响。定制足部矫形器可以改变胫骨后肌腱功能障碍患者的行走生物力学，但尚未有研究调查其对该人群爬楼梯生物力学的影响。本横断面研究旨在比较预制足部矫形器和两种定制足部矫形器模型对爬楼梯时胫骨后肌腱功能障碍患者生物力学的影响。方法选取14例疼痛性胫骨后腱功能障碍患者，分别在单独穿鞋、预制足部矫形器、中性定制足部矫形器和带5°内侧楔形和4 mm内侧后跟滑动的定制内翻足部矫形器4种实验条件下进行爬楼梯任务。使用一维统计非参数映射，比较不同条件下髋关节、膝关节、踝关节和足部的角度和力矩。结果：与普通鞋相比，中性定制足部矫形器减少了前足背屈(P <；0.001)。与鞋子相比，两种定制足部矫形器都减少了后脚外翻(P <；0.001)。与鞋子相比，定制足部矫形器的踝关节外翻力矩更大(P <；0.001)和预制足部矫形器(中性定制：P <；0.001)。中性定制和定制内翻足矫形器似乎适合于减轻胫骨后肌腱功能障碍患者的生物力学缺陷。足部矫形器对下肢生物力学的长期影响和这些变化的临床意义仍有待确定。

期刊介绍： Clinical Biomechanics is an international multidisciplinary journal of biomechanics with a focus on medical and clinical applications of new knowledge in the field. The science of biomechanics helps explain the causes of cell, tissue, organ and body system disorders, and supports clinicians in the diagnosis, prognosis and evaluation of treatment methods and technologies. Clinical Biomechanics aims to strengthen the links between laboratory and clinic by publishing cutting-edge biomechanics research which helps to explain the causes of injury and disease, and which provides evidence contributing to improved clinical management. A rigorous peer review system is employed and every attempt is made to process and publish top-quality papers promptly. Clinical Biomechanics explores all facets of body system, organ, tissue and cell biomechanics, with an emphasis on medical and clinical applications of the basic science aspects. The role of basic science is therefore recognized in a medical or clinical context. The readership of the journal closely reflects its multi-disciplinary contents, being a balance of scientists, engineers and clinicians. The contents are in the form of research papers, brief reports, review papers and correspondence, whilst special interest issues and supplements are published from time to time. Disciplines covered include biomechanics and mechanobiology at all scales, bioengineering and use of tissue engineering and biomaterials for clinical applications, biophysics, as well as biomechanical aspects of medical robotics, ergonomics, physical and occupational therapeutics and rehabilitation.
