Abstract

Background

This study quantified thumb movement in patients with trapeziometacarpal osteoarthritis and carpal tunnel syndrome and examined the characteristics of each disorder using three-dimensional motion analysis.

Methods

Twenty-three hands of 23 patients with trapeziometacarpal osteoarthritis, 88 hands of 73 patients with idiopathic carpal tunnel syndrome, and 29 hands of 20 healthy volunteers were included in this study; three-dimensional thumb kinematics were measured during the circumduction task using a retroreflective surface-based marker method.

Findings

Trajectory of thumb tip reduced in both patient groups compared to healthy controls, with carpal tunnel syndrome exhibiting the flattening shape. Trapeziometacarpal osteoarthritis patients had decreased range of motion in all directions at the trapeziometacarpal joint, while maintaining flexion-extension at the metacarpophalangeal and interphalangeal joints. Carpal tunnel syndrome patients showed reduced motion particularly in metacarpophalangeal and interphalangeal flexion-extension. Joint contribution analysis revealed decreased trapeziometacarpal involvement and increased compensatory metacarpophalangeal and interphalangeal movements in trapeziometacarpal osteoarthritis, while carpal tunnel syndrome showed impaired metacarpophalangeal abduction.

Interpretation

This study provides novel insights into the distinct kinematic characteristics of trapeziometacarpal osteoarthritis and carpal tunnel syndrome, offering potential for improved screening and assessment of thumb motor impairments in these conditions.

Evidence Level: Diagnostic LEVEL III.

腕管综合征与斜跖骨关节炎拇指运动的差异

本研究量化了梯形腕骨关节炎和腕管综合征患者的拇指运动，并使用三维运动分析检查了每种疾病的特征。方法选取23例斜跖骨关节炎患者的23只手、73例特发性腕管综合征患者的88只手和20名健康志愿者的29只手进行研究；在绕行任务期间，使用基于反射表面的标记方法测量了三维拇指运动学。研究发现：与健康对照组相比，两组患者的拇指尖轨迹均有所减少，腕管综合征患者的拇指尖呈扁平状。梯形腕骨关节炎患者在梯形腕关节各方向的活动范围减小，而在掌指关节和指间关节保持屈伸。腕管综合征患者表现为活动减少，特别是掌指关节和指间屈伸。关节贡献分析显示，在梯形腕骨关节炎中，梯形腕关节受累减少，代偿性掌指关节和指间运动增加，而腕管综合征表现为掌指关节外展受损。解释：本研究提供了关于斜方骨性关节炎和腕管综合征的独特运动学特征的新见解，为改进这些疾病中拇指运动损伤的筛查和评估提供了潜力。证据等级：诊断III级。

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.
