研究的目的是检验基于目标追逐的协调施力能力的试行和日常可靠性和敏感度，要求30名大学生使用条形图和波形形式的两个视觉图像，将他们的握力与个人计算机显示器上显示的不断变化的需求值相匹配。这个变量是随着时间的推移，要求的握力和产生的握力之间的差值之和。分析表明，条形图和波形显示的组内相关系数(ICC)很高(ICC=0.87，ICC=0.95)。对于稳定个体的三次测量之间的差异的95%的间隔，对于条形图是−14.8%到99.3%，对于波形显示是−3.5%到113.6%。每日测量的单尾配对t检验显示，条形图和波形显示均有显著改善(p<；0.05)。对于条形图和波形显示，日常测量的ICCS为低到中等(ICC=0.33到0.71，ICC=0.48到0.76)。对于日常测量，两个试验的测量之间的一致限度为条形图的−112.2至218.6%和波形显示的−139.2至352.8%。条形图和波形显示的试验间和日常测量的重复性系数分别为141和173%，152和176%。每项测试之间的一致性范围相对较大。我们认为，这些直观地引导力量反应的测试，对于客观地记录协调施加武力的能力是有用的。
The purpose was to examine trial-to-trial and day-to-day reliability and sensitivity for measurements of the ability to coordinate exertion of force based on target-pursuit, 30 college students were required to match their grip strength to a changing demand value appearing on the display of a personal computer, using two visual images in the form of a bar chart and waveform. The variable was the sum of the differences between demanded and produced grip strength over time. Analysis indicated high intraclass correlation coefficients (ICC) for bar chart and waveform displays (ICC = .87, ICC = .95, respectively). The limits of agreement, designating the interval comprising 95% of the differences between three measurements in a stable individual, were −14.8 to 99.3% for the bar chart and −3.5 to 113.6% for the waveform displays. One-tailed, paired t tests of the day-to-day measurements showed significant (p < .05) improvement in both the bar chart and waveform displays. ICCs for day-to-day measurements were low-to-moderate for bar chart and waveform displays (ICC = .33 to .71, ICC = .48 to .76, respectively). The limits of agreement between measurements of two trials for day-to-day measurements were −112.2 to 218.6% for the bar chart and −139.2 to 352.8% for the waveform displays. The repeatability coefficients of trial-to-trial and day-to-day measurements for bar chart and waveform displays were 141 and 173%, and 152 and 176%, respectively. The limits of agreement between each test were relatively wide. We believe that these tests, on which the force response is visually guided, can be useful in objectively documenting the ability to coordinate exertion of force.
