The objective was to conduct a methodological pilot study to analyze wheelchair propulsion upper limb kinematics in standard competitive play considering the functional classification of each athlete. Ten basketball players with a functional classification ranging from 1 to 4 were included in the study. Four camcorders (Kinescan-IBV) and a treadmill for wheelchairs were used. Temporal parameters were analyzed and the upper limb kinematics was obtained using ISB recommendations. The value of the temporal parameters such as push phase duration, the ratio of push phase/recovery phase, contact, and propulsion angle seems to reduce as the functional classification increases. A methodological protocol has been developed that allows the analysis of kinematic characteristics of wheelchair propulsion in basketball players taking into account their functional classification.
目的是进行一项方法学试点研究，以分析在标准竞技比赛中考虑每位运动员功能分级的轮椅推进上肢运动学。该研究纳入了10名功能分级为1至4级的篮球运动员。使用了四台摄像机（Kinescan - IBV）和一台轮椅跑步机。分析了时间参数，并根据国际生物力学学会（ISB）的建议获取了上肢运动学数据。随着功能分级的增加，诸如推阶段持续时间、推阶段/恢复阶段的比率、接触角和推进角等时间参数的值似乎会降低。已经制定了一种方法学方案，该方案能够在考虑篮球运动员功能分级的情况下分析轮椅推进的运动学特征。
