智能吞咽障碍评测与训练系统对吞咽功能评估的重测信度

Test - retest reliability of swallowing assessment by digital accelerometry for swallowing imaging

目的研究智能吞咽障碍评测与训练系统(digital accelerometry for swallow imaging,DASITM)对吞咽功能评估的重测信度,为临床应用提供依据。方法 33例志愿者参与研究,其中老年人22例,均利用DASITM进行4次吞咽口水的测试,根据DASITM系统自带软件分析结果,记录4次测试的吞咽波峰、吞咽启动时间和吞咽持续时间平均值,并于1周内重复测试1次。将其数据利用SPSS17.0软件进行组内相关系数(ICC)检验分析。结果全部受试者的吞咽波峰和持续时间均具有极好的重测信度(ICC=0.767～0.914);全部受试者的吞咽启动时间具有中等程度的重测信度(ICC=0.410,),而老年受试者的启动时间重测信度较差(ICC为0.318)。结论 DASITM在吞咽波峰和持续时间上有极好的重测信度,在吞咽启动时间上重测信度为中等,该设备无创、便携、价廉,可以用于吞咽障碍患者的临床评估和治疗。

Objective To determine the test-retest reliability of swallowing function assessment by digital accelerometry for swallowing imaging(DASITM),specially for the elderly.Methods Thinty-three volunteers were assessed dry swallowing 4 times with DASITM,get the mean data of peak of swallowing(PS),onset of swallowing(OS) and duration of swallowing(DS) with the Software providing imaging and physiology measurements.Retest was performed in a week.Statistics using software SPSS 17.0 obtained the intraclass correlation coefficient(ICC) of AS,OS and DS.Results The ICC of AS and DS were 0.767-0.914(P < 0.01),had very good test-retest reliability.The all volunteers’ICC of OS was 0.410(P > 0.05),had medium test-retest reliability.The OS’test-retest reliability in the elderly was poor.Conclusions DASITM has good test-retest reliability in swallowing assessment,it is non-invasive,portable,cheap,and feasible for most dysphagia patients.
