The Shoulder posterior circumflex humeral artery Pathology and digital Ischemia - questionnaire (SPI-Q) has been developed to enable periodic surveillance of elite volleyball players, who are at risk for digital ischemia. Prior to implementation, assessing reliability is mandatory. Therefore, the test-retest reliability and agreement of the SPI-Q were evaluated among the population at risk. A questionnaire survey was performed with a 2-week interval among 65 elite male volleyball players assessing symptoms of cold, pale and blue digits in the dominant hand during or after practice or competition using a 4-point Likert scale (never, sometimes, often and always). Kappa (κ) and percentage of agreement (POA) were calculated for individual symptoms, and to distinguish symptomatic and asymptomatic players. For the individual symptoms, κ ranged from "poor" (0.25) to "good" (0.63), and POA ranged from "moderate" (78%) to "good" (97%). To classify symptomatic players, the SPI-Q showed "good" reliability (κ = 0.83; 95%CI 0.69-0.97) and "good" agreement (POA = 92%). The current study has proven the SPI-Q to be reliable for detecting elite male indoor volleyball players with symptoms of digital ischemia.
肩旋肱后动脉病理与手指缺血问卷（SPI-Q）已被开发出来，用于对有手指缺血风险的精英排球运动员进行定期监测。在实施之前，评估其可靠性是必不可少的。因此，在有风险的人群中评估了SPI-Q的重测可靠性和一致性。对65名精英男性排球运动员进行了问卷调查，间隔两周，使用4分李克特量表（从不、有时、经常、总是）评估他们在训练或比赛期间或之后优势手出现手指发冷、苍白和发蓝症状的情况。计算了个体症状的kappa（κ）值和一致性百分比（POA），以区分有症状和无症状的运动员。对于个体症状，κ值范围从“差”（0.25）到“好”（0.63），POA范围从“中等”（78%）到“好”（97%）。为了对有症状的运动员进行分类，SPI-Q显示出“好”的可靠性（κ = 0.83；95%CI 0.69 - 0.97）和“好”的一致性（POA = 92%）。当前研究已证明SPI-Q在检测有手指缺血症状的精英男性室内排球运动员方面是可靠的。
