A number of tests for evaluating dysphagia without using videofluoroscopic examination of swallowing (VF) or videoendoscopic evaluation of swallowing (VE) have been developed. The simple swallowing provocation test (SSPT) is unique because it is performed while in a supine position and does not require the patient's cooperation. However, whether the SSPT detects aspiration or penetration correctly is unclear because its validity determined by VF or VE has not been evaluated. Therefore, we determined the sensitivity, specificity, and predictive accuracy of SSPT followed by VF in 45 patients. The sensitivities of the first-step and the second-step SSPT for the detection of aspiration, silent aspiration, or penetration were 72-75% and 13-17%, respectively; the specificities of the first-step and the second-step SSPT were 38-44% and 80-89%, respectively; and the predictive accuracies of the first-step and the second-step SSPT were 58-67% and 31-49%, respectively. These data suggest that SSPT has limited applicability as a screening tool for aspiration, silent aspiration, or penetration because of its low sensitivity. This test may be useful for patients who cannot undergo other tests due to cognitive and/or linguistic dysfunction.
已经开发出了许多无需使用吞咽荧光透视检查（VF）或吞咽视频内镜评估（VE）的吞咽障碍评估测试。简单吞咽激发试验（SSPT）是独特的，因为它是在仰卧位进行的，不需要患者的合作。然而，SSPT 是否能正确检测到误吸或渗透尚不清楚，因为其通过 VF 或 VE 确定的有效性尚未得到评估。因此，我们在 45 名患者中确定了 SSPT 后 VF 的敏感性、特异性和预测准确性。第一阶段和第二阶段 SSPT 对误吸、无声误吸或渗透的检测的敏感性分别为 72-75%和 13-17%；第一阶段和第二阶段 SSPT 的特异性分别为 38-44%和 80-89%；第一阶段和第二阶段 SSPT 的预测准确性分别为 58-67%和 31-49%。这些数据表明，由于敏感性低，SSPT 作为误吸、无声误吸或渗透的筛选工具的适用性有限。对于因认知和/或语言功能障碍而无法进行其他测试的患者，该测试可能有用。
