To develop a model of the dynamics of functioning, disability and contextual factors which harmonises with the International Classification of Functioning, Disability and Health (ICF).
Model parts based on ICF were identified and a model drawing from engineering concepts was developed. The conceptual and practical applicability of the model was discussed.
The so called Friction Model was created, which incorporates the ICF entities capacity, performance, environmental factors, health condition, body functions and structures, and personal factors. Friction describes the interaction between a person and his or her environment. The coefficient of friction is defined as the ratio between capacity and performance.
Carrying conceptual strengths and limitations, the Friction Model appears to offer opportunities for practical applications, including ICF-based alternatives to health-economic analyses. Harmonising with the ICF model and terminology, the model uses friction to describe the interaction between a person and the environment. The coefficient of friction can be used as a simple measure of how facilitating an environment is. The applicability is not limited to functioning of people with impairments.
开发一个与国际功能、残疾和健康分类（ICF）协调一致的功能、残疾和情境因素动态模型。
确定基于 ICF 的模型部分，并开发源自工程概念的模型。讨论了模型的概念和实际适用性。
创建了所谓的摩擦模型，其中包含了 ICF 实体的能力、表现、环境因素、健康状况、身体功能和结构以及个人因素。摩擦描述了人与环境之间的相互作用。摩擦系数定义为能力与表现的比值。
尽管存在概念上的优势和局限性，摩擦模型似乎为实际应用提供了机会，包括基于 ICF 的健康经济分析替代方案。该模型与 ICF 模型和术语协调一致，使用摩擦来描述人与环境之间的相互作用。摩擦系数可用作描述环境促进程度的简单指标。其适用性不仅限于有残障人士的功能。
