Increasing interest in upper extremity biomechanics has led to closer investigations of both segment movements and detailed joint motion. Unfortunately, conceptual and practical differences in the motion analysis protocols used up to date reduce compatibility for post data and cross validation analysis and so weaken the body of knowledge. This difficulty highlights a need for standardised protocols, each addressing a set of questions of comparable content. The aim of this work is therefore to open a discussion and propose a flexible framework to support: (1) the definition of standardised protocols, (2) a standardised description of these protocols, and (3) the formulation of general recommendations.
Proposal of a framework for the definition of standardized protocols.
The framework is composed by two nested flowcharts. The first defines what a motion analysis protocol is by pointing out its role in a motion analysis study. The second flowchart describes the steps to build a protocol, which requires decisions on the joints or segments to be investigated and the description of their mechanical equivalent model, the definition of the anatomical or functional coordinate frames, the choice of marker or sensor configuration and the validity of their use, the definition of the activities to be measured and the refinements that can be applied to the final measurements. Finally, general recommendations are proposed for each of the steps based on the current literature, and open issues are highlighted for future investigation and standardisation.
Standardisation of motion analysis protocols is urgent. The proposed framework can guide this process through the rationalisation of the approach.
人们对上肢生物力学的兴趣日益浓厚，这促使对节段运动和详细关节运动进行更深入的研究。不幸的是，迄今为止使用的运动分析协议在概念和实践上存在差异，降低了数据后期处理和交叉验证分析的兼容性，从而削弱了知识体系。这一困难凸显了对标准化协议的需求，每个协议都应解决一组具有可比内容的问题。因此，本研究的目的是展开讨论并提出一个灵活的框架，以支持：（1）标准化协议的定义；（2）这些协议的标准化描述；（3）一般性建议的制定。
提出一个用于定义标准化协议的框架。
该框架由两个嵌套的流程图组成。第一个流程图通过指出其在运动分析研究中的作用来定义什么是运动分析协议。第二个流程图描述了构建协议的步骤，这需要对要研究的关节或节段做出决策，并描述其力学等效模型，定义解剖学或功能坐标框架，选择标记物或传感器配置及其使用的有效性，定义要测量的活动以及可应用于最终测量的细化方法。最后，根据当前文献对每个步骤提出一般性建议，并突出未决问题以供未来研究和标准化。
运动分析协议的标准化迫在眉睫。所提出的框架可以通过方法的合理化来指导这一过程。
