Trunk function is a core factor to allocate Boccia players with cerebral palsy in BC1 and BC2 sport classes, according to the Boccia International Sports Federation (BISFed). However, the appropriateness of the current test to assess trunk function has never been studied to determine its reliability, validity and sensitivity to discriminate between different levels of impairment. Thirty-six players (BC1 = 13 and BC2 = 23) took part in this study. Trunk control was assessed through the BISFed trunk function scale (TFS) and a posturographic test battery consisting of two static and three dynamic tasks. The inter-rater reliability for the BISFed TFS was set at 94.44% of agreement. Moderate-to-high correlations were obtained between posturographic tasks (0.39 < r < 0.96; < 0.05-0.01), while the BISFed TFS only correlated with two of the dynamic tasks and the overall dynamic score (-0.38 < r < -0.51; < 0.05). The BISFed TFS was not able to discriminate between sport classes, whereas the static posturographic task did so ( = 0.004). Even though the current BISFed TFS presented good inter-rater reliability, it does not seem to have enough sensitivity to discriminate between BC1 and BC2. Although the static posturographic tasks were able to discriminate between sports classes, it seems necessary to develop new field tests assessing participants' trunk stabilization abilities.
根据 boccia 国际体育联合会（BISFed）的说法，躯干功能是将脑瘫 boccia 运动员分配到 BC1 和 BC2 运动级别的核心因素。然而，目前用于评估躯干功能的测试的适用性从未被研究过，以确定其可靠性、有效性和区分不同损伤水平的敏感性。三十六名运动员（BC1 = 13 名，BC2 = 23 名）参与了这项研究。通过 BISFed 躯干功能量表（TFS）和由两项静态和三项动态任务组成的姿势描记测试组来评估躯干控制。BISFed TFS 的评分者间信度设定为一致性的 94.44%。姿势描记任务之间获得了中度到高度的相关性（0.39 < r < 0.96；< 0.05 - 0.01），而 BISFed TFS 仅与两项动态任务和总体动态得分相关（-0.38 < r < -0.51；< 0.05）。BISFed TFS 无法区分运动级别，而静态姿势描记任务可以做到（= 0.004）。尽管当前的 BISFed TFS 表现出良好的评分者间信度，但它似乎没有足够的敏感性来区分 BC1 和 BC2。虽然静态姿势描记任务能够区分运动级别，但开发新的现场测试来评估参与者的躯干稳定能力似乎是必要的。
