Occupational therapy practitioners need modern tools for the assessment of maximal grip strength in clinical and remote settings.
To establish the (1) interrater reliability and (2) precision of the GripAble among three raters with different expertise in occupational therapy when testing healthy participants, and to (3) evaluate the relative reliabilities of different approaches to estimating grip strength (i.e., one trial, mean of two trials, and the mean of three trials).
Measurement study.
Minnesota Translational Musculoskeletal and Occupational Performance Research Lab, University of Minnesota, Minneapolis.
Thirty volunteers, age ≥18 yr, without any hand problems.
Using GripAble, three occupational therapy raters with varied experience measured the maximal grip strength of the dominant and nondominant hands of all participants. Using the mean of three trials when testing grip strength with GripAble adds precision.
GripAble has excellent interrater reliability (i.e., intraclass correlation coefficient > .75) and acceptable precision (minimal detectable change < 15%) among healthy adults.
GripAble allows occupational therapy practitioners with different experiences to assess grip strength in healthy hands quickly, precisely, and with excellent reliability. Additional research is needed on its psychometrics in clinical populations and capacities in remote monitoring and exergaming. Plain-Language Summary: The results of this study show that grip strength, an important biomarker and commonly assessed construct in occupational therapy, can be evaluated reliably, precisely, and rapidly with GripAble. The use of GripAble by occupational therapy practitioners in clinical settings may help to build an infrastructure for remote measurements and exergaming interventions in the future.
职业治疗师在临床和远程环境中评估最大握力时需要现代工具。
在测试健康参与者时，确定（1）三位职业治疗师的 GripAble 之间的组内信度和（2）精度，以及（3）评估不同方法估计握力的相对可靠性（即一次试验、两次试验的平均值和三次试验的平均值）。
测量研究。
明尼苏达州转化肌肉骨骼和职业表现研究实验室，明尼苏达大学，明尼阿波利斯。
30 名志愿者，年龄≥18 岁，无手部问题。
使用 GripAble，三位经验不同的职业治疗师评估了所有参与者的惯用手和非惯用手的最大握力。当使用 GripAble 测试握力时，三次试验的平均值可增加精度。
GripAble 在健康成年人中具有出色的组内信度（即，组内相关系数>.75）和可接受的精度（最小可检测变化< 15%）。
GripAble 允许具有不同经验的职业治疗师快速、精确且可靠地评估健康手中的握力。需要进一步研究其在临床人群中的心理测量学以及远程监测和运动游戏中的能力。
这项研究的结果表明，握力作为职业治疗中一个重要的生物标志物和常用评估指标，可以通过 GripAble 可靠、精确和快速地进行评估。职业治疗师在临床环境中使用 GripAble 可能有助于为未来的远程测量和运动游戏干预建立基础设施。
