长期卧床高龄老年人握力的重测信度

Test-retest Reliability of Grip Strength Assessment in Bed-ridden Senile Patients

目的探讨长期卧床80岁以上高龄老年人握力的重测信度。方法对20例卧床时间超过1年的80岁以上老年人取卧姿,采用JAMAR握力器分别测试其左、右手的握力。第1次测试结束7d后,在同一时间段由同一测试者重复测试1次。结果左手握力和右手握力的组内相关系数(ICC)分别为0.985和0.970。结论长期卧床高龄老年人的握力测试具有较高的重测信度。

Objective To study the test-retest reliability of grip strength assessment in the bed-ridden elders above 80 years old. Methods The left and right grip strength of 20 patients who were bed-ridden for more than 1 year, older than 80 years were measured on the lying position with the JAMAR Hand Dynamometer, and they were measured again in the same way by the same conner a week later. Results The intraelass correlation coefficient were 0. 985 and 0. 970 in the grip strength of left and right hands, respec- tively. Conclusion The assessment of grip strength showed good test-retest reliability in the bed-ridden elders above 80.
