世界卫生组织给mobility(活动能力)一词所下定义为“个体在其周围环境中有效地四处走动之能力。”最近Bennekom等提出更为广义的定义:“活动能力是移动自己以及改变和维持体位的过程。”对活动能力进行评定能对医师的诊疗工作有所帮助。本项研究的目的在于比较临床上评定活动能力常用的4种方法的效度和信度。 WHO defines the term mobility as “the ability of individuals to effectively move around in their surroundings.” Recently Bennekom et al. Proposed a more generalized definition: “Mobility is the ability to move and change and maintain Position of the process. ”The ability to assess the activities of the physician’s diagnosis and treatment can be helpful. The purpose of this study was to compare the validity and reliability of the four commonly used methods for assessing activity in the clinic.
