To summarize and critically appraise the quality of studies investigating psychometric properties of pinch strength assessment.
Medical literature up to February 2024 was searched for studies reporting on at least one measurement property of pinch strength assessment. The quality of the evidence and the risk of bias were rated using COSMIN 2018 guidelines.
Thirty-three studies (1962 participants) were included. The majority (16/19) of reliability studies were of adequate to very good quality. Seven of 12 studies of validity were rated as adequate or very good. The quality of the eight responsiveness studies was adequate. Reliability was good to excellent (ICC > 0.75) for neurological conditions, and excellent (ICC > 0.90) for musculoskeletal disorders and healthy participants. Pinch strength showed strong to very strong correlations with grip strength ( = 0.72-0.92), moderate to strong correlations with assessments of dexterity ( = 0.78-0.80), and weak to moderate correlation with patient-reported outcome measures ( = 0.03-0.50). Varied results were found for pinch strength responsiveness in a small number of studies.
Pinch strength assessment is reliable. Validity and responsiveness are less reported, but there is a strong correlation between pinch and grip strength, and a moderate correlation with dexterity.
总结并批判性评估关于捏力评估心理测量特性的研究质量。
检索截至2024年2月的医学文献，查找报告捏力评估至少一项测量特性的研究。使用COSMIN 2018指南对证据质量和偏倚风险进行评级。
纳入33项研究（1962名参与者）。大多数（16/19）可靠性研究质量为良好至非常好。12项有效性研究中有7项被评为良好或非常好。8项反应度研究质量良好。神经疾病的可靠性良好至优秀（组内相关系数>0.75），肌肉骨骼疾病和健康参与者的可靠性优秀（组内相关系数>0.90）。捏力与握力呈强至非常强的相关性（r = 0.72 - 0.92），与灵巧性评估呈中度至强相关性（r = 0.78 - 0.80），与患者报告结局指标呈弱至中度相关性（r = 0.03 - 0.50）。少数研究中捏力反应度的结果各异。
捏力评估是可靠的。有效性和反应度的报告较少，但捏力与握力之间存在强相关性，与灵巧性存在中度相关性。
