The handgrip strength test is widely used by clinicians; however, little has been investigated about its reliability when used in subjects with Parkinson disease (PD). The purpose of this study was to investigate the test-retest reliability of the handgrip strength test for subjects with PD.
The PD group consisted of 15 patients, and the control group consisted of 15 healthy subjects. Each patient performed 3 pain-free maximal isometric contractions on each hand on 2 occasions, 1 week apart. Intraclass correlation coefficient (ICC), standard error of measurement (SEM), and 95% limits of agreement (LOA) were calculated. The 2-way analysis of variance (ANOVA) was conducted to determine the differences between sides and groups.
Test-retest reliability of measurements of grip strength was excellent for dominant (ICC = 0.97; P = .001) and non-dominant (ICC = 0.98; P = .001) hand of participant with PD and (ICC = 0.99; P = .001) and (ICC = 0.99; P = .001) respectively, of healthy group.
The Jamar hand dynamometer had fair to excellent test-retest reliability to test grip strength in participants with PD.
握力测试被临床医生广泛使用；然而，关于其在帕金森病（PD）患者中使用时的可靠性研究较少。本研究的目的是调查PD患者握力测试的重测可靠性。
PD组由15名患者组成，对照组由15名健康受试者组成。每位患者在两只手上各进行3次无痛的最大等长收缩，分两次进行，间隔1周。计算组内相关系数（ICC）、测量标准误差（SEM）和95%一致性界限（LOA）。进行双向方差分析（ANOVA）以确定两侧和两组之间的差异。
PD患者优势手（ICC = 0.97；P = 0.001）和非优势手（ICC = 0.98；P = 0.001）以及健康组优势手（ICC = 0.99；P = 0.001）和非优势手（ICC = 0.99；P = 0.001）的握力测量重测可靠性均极佳。
Jamar握力计在测试PD患者握力时具有较好至极佳的重测可靠性。
